In the capillaries surrounding the alveoli in the lungs
Oxygen and other gases pass through the capillaries.
oxygen
What makes you pass out is the lack of oxygen you get if your taking to many hits too quickly and not breathing in between them or if you hold it in for long enough and you pass out from oxygen deficicency.
This would be the cardiovascular system. The heart is the pump and the blood travels through arteries carrying oxygen for the body and the veins return the de-oxygenated blood back to the heart. The blood must pass through the lungs to pick up the oxygen and release carbon dioxide.
oxygen from lungs pass to the blood capilleries in which it enter in red blood cells which carry 4 molecules of oxygen by combinig with one molecule of Hb Oxygen from blood transfer to cells where it helps in metabolic reaction and cellular respiration.
All of them
No, the cardiovascular system does not produce the red blood cells. It serves as a channel in which blood and other fluids pass through. It is the hematopeotic system that produces the blood in the bone marrow stimulated by erythropoietin produced by the kidneys in response to low oxygen perfusion.
The digestive system breaks down and absorbs food. The circulatory system circulates blood through your body. The respiratory system exchanges oxygen and carbon dioxide. With the help of the circulatory system it transfers these gases to and from your cells.
if you stop breathing due to blockages in the lungs or esophagus, then you cannot breathe, if you pass out, your natural body system kicks in and keeps you breathing.
