Pulmonary circulation is when blood is moved from the heart and through the lungs. The blood then is circulated back to the heart again.
The right ventricle receives blood that has circulated through the body via the right atria. it then pumps the blood through the pulmonic valve to the lungs where the blood becomes reoxygenated for circulation. :)
Arterial blood is blood that has picked up oxygen (oxygenated) in the lungs and is being circulated through the body. Venous blood is blood that has been circulated and is now de-oxygenated (low Oxygen content) and is being returned to the lungs to start the process over.
The blood runs through them
Oxygen (O2) enters the blood through inhalation and is circulated throughout the body. Carbon Dioxide (CO2) is filtered out of the blood as a waste product and exhaled.
when you breath in oxygen, it goes through the bronchi in your lungs, through the bronchioles and then to the alveoli from there it goes to the capillaries where the oxygen dissolves into the blood through tissue that is one cell thick. as that happens, the carbon dioxide that is in your blood already, dissolves out into the alveoli. then it travels through the bronchioles, bronchi, and to your lungs, then out your nose.
William Harvey first realized that blood circulated in 1491-1492
They carry blood from the arteries into the various organs and tissue's.They also bring the blood, that has already been circulated, back to the heart to be filtered ,and for more oxygen to permeate the blood for the next cycle.And its "vains" not "vines".
