A closed circulatory system means that the blood is carried through the vessels
A open circulatory system means that the blood is not carried through vessels it just bathes the organs in the space of the body
The blood that travels through the body is made up of two main things, fluid called plasma and cells that float in the plasma
Platelets have a specific roles when it comes to blood clotting. They activate a event that makes it possible for fibrinogen to change into threads called fibrin. Fibrin then creates a net that traps blood cells and platelets to form a clot.
Red Blood Cells and Hemoglobin
White Blood Cells and Lymphocytes
Make up 5% of blood volume
White Blood Cells fight off disease in your body so they are phagocytes which means they are good at eating viruses, bacteria, parasites, dead cells, and more.
They are also Lymphocytes which help defend your immune system
Lymphocytes come in two types of cells B-Cells and T-Cells
Red Blood Cells
White Blood Cells
B-cells make antibodies for specific viruses, bacteria, or other harmful things in your body
T-Cells have two roles. One is to help the B-cells and T-cells become helper t-cells that can divide and grow new cells.
The other role is to help cells that have been infected by a viruses
So we know that viruses can’t reproduce so they pretend to be parasites and go inside our cells . In order for helper T-cells to kill the cell that has be attacked they make Killer T-cells.
Red Blood Cell
I t has two pumps in one.
Right side receives blood from body and pumps it to the lungs
Left side receives blood from lungs and pumps it out to body
The heart has four chambers. The two right chambers at the top are called atria. They receive the blood from the body and lungs
The chambers on bottom are called ventricles they squeeze the blood out to body and lungs
The atria and ventricles work together while the atria is filling up with blood the ventricles are squeeze out blood
The heart as two heart values . The mitral value and tricuspid value let the blood flow from atria and ventricles. The aortic value and pulmonary value control the blood flow. They work together letting blood flowing forward and opening up to let blood move forward.
