What happens when blood flows past cells?
When blood capillaries flow past cells, diffusion of oxygen, wastes, and nutrients occurs. This transfer maintains cellular homeostasis.
Where does the respiratory system transfer oxygen to?
blood
What is the of aerobic dancing?
oxygen and blood flow
How countercurrent flow aids a fish in obtaining oxygen?
Many fish use countercurrent exchange in their gills to transfer oxygen from the surrounding water into their blood. This system moves water flowing across the gills, in an opposite direction to the blood flowing in gill capillaries creating the maximum efficiency of gas exchange. This flow ensures that blood is always brought near to water having a higher oxygen concentration.
The major regulator of regional blood flow in the brain is?
oxygen
How does fetal hemoglobin enhance oxygen transfer across the placenta from mother to fetus?
I'm not quite sure how it would ENHANCE oxygen transfer, but hemoglobin itself is what is in blood and is responsible for the carrying of oxygen to different parts of the body. So the hemoglobin in a fetus would just be what is used to get the oxygen from the mothers blood into its blood.
How exercise affects memory?
Exercise increases blood flow to the brain. The brain needs oxygen to function, so the more blood flow, the more oxygen, the better the brain works.
What happens when blood flows through capillaries?
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
How is coronary blood flow regulated?
Coronary blood flow is regulated by local metabolic factors. Adenosine, nitric oxide, and decreased oxygen all act as vasodilators which improve blood flow in coronary circulation.
Keep a one way flow through the heart?
It is important for blood to flow in one direction in the heart because blood can't flow backwards because it has oxygen rich blood and poor oxygen rich blood and these to types of blood cannot mix :)
What makes blood cellls?
they flow oxygen and nutrients to the organs and tissues in your body
Why does the blood flow into the lunges?
To expel Carbon Di-Oxide and collect Oxygen.
