07.02 Respiratory and Circulatory
Transcript of 07.02 Respiratory and Circulatory
By Alex Orosa
The red blood cell is made in the
bone marrow were it's then encounters
into the blood. The blood has mostly red blood cells but it also has plasma and white blood cells as well.
The red blood cell then goes through the veins (deoxygenated blood) until it gets to the heart were its pumped into the lungs.
Once in the lungs it goes to the alveoli. Then the blood cell goes through the capillaries and lastly they go through a process called cellular respiration were it exchanges its carbon dioxide for oxygen. The hemoglobin of the cell makes oxygen engage to it. The cell then goes into the oxygenated blood.
Once the cell is oxygenated it could go into the pulmonary circulation where the oxygen rich cell goes to and from the lungs back to the heart to give the heart the oxygen and nutrients it needs to keep working. It can go into the fundamental circulation were it carries the oxygen rich blood away from the heart to the rest of the body through the arteries.
Once the cells goes through the body and reaches the capillaries that expand all over the body it releases the oxygen it holds and takes the carbon dioxide waste where it goes through the veins to the heart, then the lungs. Then repeats the process once more.
