The oxygen within the blood is depleted and needs to be returned to the lungs to be re-oxygenated.
the heart pumps the blood to different part of the body
blood flow is called circulation
You see, the sarcomere fills with endoplasmic filter that permits blood flow throughout the body
as the heart beats the pulses operate like a pump, and it drives the blood up and down the blood vessels.blood with fresh oxygen goes through the arteries, and comes back with CO2 through the veins.
yes
So that they can flow to different parts of your body quickly
B/c different parts of the body require different amounts of blood flow. If all vessels were equally sized and big, then blood would hardly more in those in parts of the body that only need a little flow. If all were equally sized and small, then blood would have to flow at a whopping pressure in parts needing a lot of blood flow. By having varying sizes the body can have similar pressures in both areas that need a lot of blood as in areas only needing a little.
Exercise, sexual arousal, and embarrassment can all cause increased blood flow to different parts of the body. Increased blood flow to the digestive organs happens after a meal.
Vessels
The haert pumps blood from the arteries and to the other parts of the body while the veins take blood into the heart.
you can get gangrene in all parts of the body that blood flows. gangrene is caused by the lack of blood flow.
"It is the whole body incuding the way of the blood flow."

To maintain blood flow to all parts of the body.
not entirely, if the blood flow stops,so does the heart, but the heart is mainly used to keep the blood flowing so it can get to different parts of the body. Electricity can keep a heart pumping if the correct amount of flow is being produced so blood can be replaced for the heart but cannot sustain a human body.

No.
