Circulatory System

David Franke

The Overview


There are 4 main organs in the circulatory system. The heart. The lungs. The blood and blood vessels. and the lymph nodes.


The heart is responsible for pumping and circulating blood through the body and its organs.


The lungs breathe in air and supply the blood with it, so the blood can deliver it to the organs.

Lymph Nodes

The lymph nodes are responsible for serving as filters for the blood to dispose of the waste its carrying.

Blood Vessels

the blood and blood vessels are a fluid that transports oxygen and nutrients to the body and carry out waste products.

My Organ

My organ was the blood. here are the tissues and functions that it serves in the body


The 4 main tissues in the blood are the red blood cells, white blood cells, plasma, and platelets.


Some of the important functions that the blood performs are protecting the body from disease, carrying the DNA, and keeps you from bleeding to death from a paper cut.


There are many diseases associated with the blood. With things from a common cold, to a deadly brain bacteria. The 4 diseases I chose were, Atherosclerosis - a clogged artery leading to a heart attack, Angina Petrosis - A sharp chest pain caused by a small artery. Rhinovirus - a common cold caused by a bacteria, lastly meningitis.


Meningitis is a bacteria that destroys the layer of skin protecting you brain from bacteria and disease. Its caused by spreading a bacteria called neisseria meningitidis through kissing, coughing, or sneezing. the symptoms can be as severe as mumps, or as small as forgetting where you put something. other symptoms are Fever, severe headache, neck pain, vomiting, and seizures. The preventions are pretty basic. Vaccination, antibiotics, and a cochlear implant which restores the lost brain tissue.

Keeping Healthy

The easiest way to stay healthy with your blood is to exercise and to keep a healthy diet without too much fats.

With or Wothout?

It would be completely impossible to live without any part of this system because you would always be sick, bleed to death, unable to breathe, and unable to move.


so far the only significant advances are heart helpers that help your heart pump blood, and blood transplants.


the blood is responsible to keep the body functioning. it transports oxygen from the lungs. it gives nutrients to the brain, and it provides oxygen to the liver.


For my enrichment I found a blood cancer called multiple myeloma. This produces mutated plasma cells called myeloma cells. these cause tumors in your bone marrow and other soft tissues around it. this can lead to fatal blood clots, vomiting, easily broken bones, and constant infection.
