What else can I help you with?
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.
Why is blood flowing from lungs to the heartbrught red in color instead of dark red?
Blood flowing from the lungs to the heart is bright red because it is oxygenated. When blood passes through the lungs, it picks up oxygen, which binds to hemoglobin in red blood cells, causing the blood to appear bright red. In contrast, deoxygenated blood returning from the body to the heart is darker due to the lack of oxygen. This difference in color is primarily due to the chemical state of hemoglobin and its interaction with oxygen.
What is the last valve oxygen depleted blood must pass through before pumping to the lungs?
The last valve oxygen-depleted blood must pass through before being pumped to the lungs is the pulmonary valve. This valve separates the right ventricle from the pulmonary artery and prevents blood from flowing back into the heart. Once the blood passes through this valve, it enters the pulmonary artery and travels to the lungs for oxygenation.
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
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
