Does the heart get oxygen and nutrients from the blood flowing through it?
no. it gets it from the lungs
Explain why the blood flowing to your lung is different from those are flowing out?
Answer:Blood flowing to your lungs is full of carbon dioxide, which gets exchanged in your lungs and the blood flowing out of your lungs is clean/purified with oxygen in it.
What does the alveole do?
Looks like a bubble in the lungs; its function is to exchange gasses between the air inhaled and the blood flowing through the lungs. (Mostly oxygen into blood and CO2 out of the blood.)
What is the flow of blood between the heart and lungs called?
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
Why are there four valves in the heart?
2 of these valves (one on each side) stop blood from flowing back into the atria chambers of the heart when the heart is contracting and expelling blood. The other two are there to stop blood flowing out of the ventricles when the heart is filling up with blood. One stops blood flowing through the aorta to supply the body and the other stops it flowing through the pulmonary artery to the lungs.
Is the blood flowing from the heart to the lungs rich or poor in oxygen?
poor
Does the blood from the head flow to the lungs first before flowing to the heart?
No. Blood from the head returns to the right side of the heart and is then pumped ino the lungs. The blood from the head returns to the heart and is then sent to the lungs. If it went to the lungs before returning to the heart, that would be wasteful becase then it would have gone through the lungs twice before going to where it was needed.
What gas enters the blood through the lungs?
oxigen is the gas that enters the blood through the lungs
Where is that blood flowing to the right artreium enter?
the deoxygenated blood from whole body enters in right atrium which is then pumped to right ventricle from which it goes to lungs for oxygenation through pulmonary artery
Where does oxygen into the blood and carbon dioxide pass out of the blood?
alveoli
How does blood flow through the lungs throughout the body?
Blood is pumped by the heart. Blood leaves the heart via the arteries and returns to the heart via the veins. Blood returning to the heart goes to the lungs where it is oxygenated then pumped around the arteries
Where does blood come to lungs?
Blood enters the lungs through the pulmonary arteries.
