Digestion System!!!!!

Do you what shape the stomach is? Why food doesn't go down your windpipe? Your will know after you learn about the DIGESTIVE SYSTEM! This is your digestive system. It is made of organs.
Now let's talk about the mouth.The mouth is the first step on the digestive system. Your teeth grind the food so it can be digested.Your spit serves has a part in the digestive system. Saliva is spit. Your spit breaks down the food.
Take a bite of food. Yes do it!As you chew saliva is breaking the food down. In a few seconds it will be different. Very different. When you swallow your epiglottis closes. Epiglottis is a flap of tissue. The rhythmic contractions of the muscular walls in the esophagus pushes the food bolus toward the stomach.

To stop food from coming up the esophagus a muscle called espohageal sphincter. Which is located right above the stomach.
Now it's to the stomach.
The stomach is has dangerous gasses that can burn through carpet. Your stomach has mucus that protects it. The mucus is replaced every 3 days.
When your stomach is rumbling that is your stomach muscles working before you eat.
That is your stomach. It is not very big. It is in the shape of a duck or a j. Now we will talk about the small instant but it is really big the small instant is 13 to 20 feet long! The small instant is 25 feet but the large intestine is only 5 feet. the large instant is wider so that is how it is called large.
This is your small instant. The small instant is only one inch thick.
If your small instant was not working you would not get energy.
Now let's learn about the large instant.When the body has food it does not need it goes to the large instant.
That is the large instant.
Your large intestine is called large because it is thicker than the small instant.
 The large instant takes the water away from the waist and sends it to the rectum. That is when you use the bathroom and the digestion process is complete. Here is a video.

The Circulatory System!!!!!!!!!!!!!!!!!

 I can't believe I get to make a Circulatory Blog! This is going to be so fun! Well I have to teach you about it!
Everything goes to the heart. This video will explain but I have to tell you more! The circulatory system is an organ system.
So the circulatory system is your whole body! How about a video?

The circulatory system is what keeps you alive!
Your veins connect to everything in your body! Even to your heart! Oxygen and blood get to heart like in the video. The circulatory system is always working!!! It never stops! It takes out the bad stuff too.
 Like co2. Your heart beats at a steady rate and pushes blood into arteries. The heart is the most helpful organ in your body! Your body would not be alive without your heart! Well, I have no more to say. Here's a picture!
That is your circulatory system (heart) and this is your body!
FAST Fact: Your heart has 4 pumps. It thakes one minute for blood to go to around your body.
Well this is it! So bye!

Super Natural!!

This is the best blog ever! I am going to tell you about super Natural ghost! Do you think this is real?
Does science explain everything? Can people see a ghost or talk to them? You will find out, but first do you think this is real?

 A story of a ghost encounter. I was in my bed and some ghost started to move the bed like bounced the bed. And I looked and saw and a ghost.Do you think this is real or can science explain that? Do you?
 This is the definition. According to traditional belief, a ghost is the soul or spirit of a deceased person or animal, taken to be capable of appearing in visible form or otherwise manifesting itself to the living.
Are ghosts real? I think they are. Do you?
Is this real? Can it be!
Do you see them? There are 4 orb's and 3 human ghosts.
I do believe in ghosts.Do you think this is real? Ghost are able to come back to life. If You don't belive in them you better!
This is proof ghosts are real. What? You don't believe me! Well, see this picture!

See! Another ghost! The topic of Super Natural started by people believing in weird things, but this is real! Man I hate it when mister Sellers creepes us scary us!
There are 2 main types of ghost. 1. a dog ghost and 2. a human ghost.
That is it. I guess. Bye. I think... THE END!

Tissue attack!!!!

Well folks we got tissues! These tissues are made of lots of cells!

The are the four types of tissues are epitheial tissues, nerve tissues, connective tissues, and muscle tissues. 

Muscle tissues are made up of cells that can become shortened.  The muscles of the human body can be categorized into a number of groups which include muscles relating to the head and neck. Our body is made up of muscles.

 Connective tissues holds parts of your body together. They attach to your bones to help you move. They even make you stand up! More connective tissues are Tendons and ligaments.Tendons keeps the foot , hand,back, and leg to together. Ligaments do the other bones.

Epithelial tissues contain cells that are packed tightly together. Your outer layer of you skin is epithelial tissues.The lining of your air passage is too! Epithelial tissue lines the internal organs, helping them to carry out their functions and protecting other tissues in the organ. Is that cool or what? 

I have one thing to say about the nerve tissues. You know when you touch  something hot. Well when your hand moves away. That is nerve tissues! They send messages to your brain! Nerve tissue is  found in the brain, the spinal cord, nerves, and sensory receptors.

Tissues are freaky!
Whoa! This is a cool picture!
I hope you learned about tissues!
Well that is all for now!

Plant like Protists V.S. Plants!!!

Well folks we have plant like protists and plants but plant like protists are not plants!! We are going to look at how they are alike. Plant like protists are not plants because they don't have leaves or roots. Also plant like plants are multicellular and plant like protists are singled celled.

Plant like protists produce there own food just like plants! You might be wondering what is a protists? Well protists are one of the six types of kingdoms in the world.They are microscopic creatures. They live every where!!!  Now let's explore different types of algae! Let's go!

This is green algae. This algae can make air. They make 75% of our air!
This is dionflagellates. They make red tides.

This is brown algae.These guys are seaweed.

Here is cool red algae!

 This red plant are one of the oldest groups of eukaryotic algae, and also one of the largest, with about 5,000-6,000 species  of mostly multicellular.

 Last photo... Here is euglenoids
Euglenoids have tails to move.

Now for the video I promised. Its is about protist in action!

Another way protists and plants are alike is they both need water and need sunlight.
Moving on from protists we have... Algae!
 Algae are a large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms, such as the giant kelp that grow to 65 meters in length! Wow! I did not know that! Yes there are red,green and brown! This video is about man made algae! Let's watch it!

Algae are found in the fossil record dating back to approximately 3 billion years.
That is cool! Do you want to know a cool fact about algae?
It makes air like plants do!!!  They also make red tides(Bloody tides yuck!).Well that is it thanks for watching and reading my article.

Protists smack down!!!!

Protists are not bacteria because they have a nucleus and bacteria don't. Amoeba have a fake foot to help them move around. They eat bacteria. They have to get food like we do! We have a food store and they don't!! Paramecium have a nucleus and they have to get their food.They are different, Paramecium do not have a fake foot.
See video.

Cool right? This fake foot is really cool!!!

Protists were traditionally subdivided into several groups based on similarities or movement.
Paramecium and amoeba are alike because they have a nucleus and they attack (or hunt) for their food.
We don't do that! They both feed of bacteria.

Well that is pretty much it... One thing, they are different sizes!!! Bye!!! ;)
See you next time!

Protists smack down!!!!

Protists are not bacteria because protists have a nucleus and bacteria don't.
Amoeba have to get their own food like attack there food! So do Paramecium!

The inside of a bacteria!

The bacteria is very complex. The cell   (one celled creature) has an flagella to make it move. The flagella is a tail that makes the bacteria move.
See picture

Cool right? The cell membrane is what keeps the cell together.
The cell wall is the protector of the cell,so the bacteria has some defence.
The chromosome is it's DNA, so when the cell splits it is like this.
See video

A plasmid is a DNA molecule that is separate from, and can replicate independently of, the chromosomal DNA.[1] They are double stranded and, in many cases, circular. Plasmids usually occur naturally in bacteria, but are sometimes found in eukaryote organisms.
Ribosomes are the components of cells that make proteins from amino acids.
 The chromosome is it's DNA, so when the cell splits it is like this. Well that is it That is..... I forgot! watch this video!

Has you saw bacteria grow fast! Well Thanks for listening and have a good day.

The Bacillus is coming! The Bacillus is coming!

The Bacillus is a bacteria that is responsible for anthrax disease! This disease is painful if you get it! You can die from this disease!
This is what it looks like! Gross right? Right!

This type lives in live stock and pest such as fleas and beetles.
This type can grow or reproduce very quick! They grow in tall grass. There is not much of a cell wall. Many people can get by Bacillus! Anthrax is a very common  today.

Anthrax is the name of the disease caused by anthrax bacteria, though the correct name for the bacterium is Bacillus anthracis. There's more on this and other interesting facts about anthrax in this article.

The Shape of Anthrax Bacteria

Bacillus anthracis is a large rod-shaped spore-forming Gram-positive bacterium. The sizes of the bacteria range from 3-9 micrometres in length and 1-1.2 micrometres in width. They were the first bacterium to be shown to cause disease. In 1877 the German physician Robert Koch isolated Bacillus anthracis and grew it in pure culture, demonstrating its ability to form endospores. He produced anthrax by injecting the microbe into animals.

Bacillus anthracis are soil-based microbes that usually exist in the endospore state. These spores are particularly robust in that they can survive for years, sometimes decades under extremes of temperature, or harsh chemical environments, and on substrates where there are low levels of nutrients.

Bacillus anthracis Pathogenesis

The potency of anthrax bacteria are due to their virulence factors which are coded for by two plasmids pX01 and pX02.

The pX01 plasmid codes for three toxins that can cause haemorrhage, necrosis, and oedema. The pX02 plasmid encodes three genes that are involved in the production of the polyglutamyl capsule that inhibits host phagocytosis of the vegetative form of the bacterium. Both plasmids are needed for the bacteria to be able to cause anthrax. If either are inhibited the bacteria are said to be attenuated. Infection with Bacillus anthracis occurs after a spore has either managed to get in via a break or cut in the skin or via mucosa.


Anthrax is a serious, sometimes fatal disease of animals and humans. It is not passed directly from one infected person or animal coming into contact with another; it is spread by spores. The illness can be treated by vaccines, and it sometimes responds to antibiotics.

Cutaneous anthrax

The most common form of anthrax is cutaneous anthrax, which accounts for about 95% of all cases. The spores can enter skin cuts, and people who work with dead animals, such as those in abattoirs are at most risk. The spores cause the formation of black necrotic lesions, and if left untreated they can cause blood poisoning.

Inhalation anthrax

Caused by the inhalation of endospores by humans or animals. It is a disease of the lungs and the spores are usually picked up by macrophages, and transported to the lymph nodes in the chest cavity. But the spores germinate to produce active bacteria which split the macrophages and release the toxins into the bloodstream that cause haemorrhaging and tissue decay.

Gastrointestinal anthrax

Caused when endospores enter the gastrointestinal tract, usually from the consumption of infected meat.

Deliberate Infection

Bacillus anthracis has been used by terrorists, various armed forces around the world, and perhaps most famously in the 2001 anthrax attacks in the United States, where letters containing anthrax spores were sent to media outlets and two Democratic senators. Five people were killed, and 17 injured. The FBI's prime suspect was identified in 2008. He was the late Dr Bruce Ivins, who worked at the army biological weapons laboratory in Fort Detrick, Maryland.
