In air through the passageways to the lungs, by diffusion through the alveoli into the blood, by diffusion out of the blood into the cells and through the cells into the mitochondria - where it ceases to exist as oxygen and becomes water.
A blood circuit is the pathway blood travels from the heart out of the aorta to the rest of the body (oxygenated blood), then (deoxygenated blood) returns back to the heart to be sent to the lungs to exchange CO2 for oxygen then returns back to the starting point to leave the heart through the aorta again. A blood circuit is the pathway blood takes from a certain point then eventually returning back to that point.
A vein. Your veins take blood back to the heart to be pumped to the lungs to get oxygen. When your veins flow blood back to the heart, it goes through the left side of your heart.
Describe the pathway of blood through the heart and lungs relating to pressure and volume? Describe the pathway of blood through the heart and lungs relating to pressure and volume?
Oxygen does not push blood through the body, the heart does.
Oxygen-poor blood enters the heart through the right atrium
Oxygen enters the respiratory system through the nose or mouth and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the tiny air sacs called alveoli and is then transported into the bloodstream by binding to hemoglobin in red blood cells. The oxygen-rich blood is pumped by the heart to the rest of the body, where it is delivered to cells for energy production.
The coronary pathway takes blood to the heart.Related Information:Coronary arteries surround the heart and provided the muscles of the heart with blood.
Oxygen rich blood travels through the Arteries and Oxygen poor blood travels through the Veins.EXCEPT: Oxygen poor Blood traveling from the heart to the lungs goes through the Pulmonary Arteries and Oxygen rich blood going back to the heart from the lungs travels through the Pulmonary Veins.
Blood carries oxygen through out your body. Your lungs inhale oxygen and the blood cells carry the oxygen to your heart. Then the heart makes more blood cells to carry more oxygen to pump more blood.
It pumps oxygen and blood through your system.
Oxygen enters the body through the nose or mouth, travels down the trachea into the lungs, where it is absorbed into the bloodstream through tiny air sacs called alveoli. The oxygen-rich blood is then pumped by the heart to all parts of the body, delivering oxygen to cells and tissues for energy production.
Yes, the blood from the lungs is rich in oxygen. Since you breathe in oxygen and nutrients through your nose/mouth to the lungs, the oxygen and nutrients are absorbed in the lungs and go through the blood stream into the heart
