- When you exercise, you need to move a lot, so you'll need more blood to carry oxygen and do gas exchange to transfer energy.

Does the stomach gets more blood during exercise?
No, the stomach and intestines get LESS blood during exercise. The blood is needed in the muscles being used and is shunted there instead of digestive organs
Why does blood flow to the gut and liver increases during strenuous exercise?
Because the blood is diverted to the working muscles instead, as they need the more blood in order to provide oxygen for aerobic respiration
Why does blood pressure increase during exercise?
As we exercise, we use our muscles. Our muscles need oxygen to function. Therefore, the more we exercise, or the harder we exercise, the more oxygen we need. In order for our muscles to get that extra oxygen, we need to breathe more. The oxygen then enters our blood and our hearts beat stronger and faster in order for the oxygen to reach the muscles as quickly as possible, thus why our blood pressure increases.
During exercise a lot more blood is distributed to the working muscles how is this achived?
heart pumps faster.
Why does blood flow slowly in a kidney during a vigorous exercise?
Blood flow to the kidneys and abdomen decreases duringexercise because the muscles need more oxygen, and so, the blood vessels in them dilate. This causes more blood to go to the muscles, leaving less blood in the rest of the body.
What happens to the cardiovascular system immediately during exercise?
the heart increases in rythm and pumps more blood to the muscles
How does the heart allow us to exercise?
it pumps the blood to the muscles to do more exercise
Does exercise get your blood flowing?
Yes, your muscles need more blood pumping to them when they are getting
Why does your face go red during exercise even though the sympathetic nervous system is activated which should divert your blood away from the skin and to your muscles instead?
The control of blood flow during exercise is more complicated than at first glance. At lower intensity exercise or at the start of exercise one of the main problems is heat. The blood carreis heat from the core to the skin allowing it to escape. During exercise heat would build up to dangerous levels is this system wasnt in place. However after more time the requirement of the muscles for oxygen outweighs the need to remove heat and so the blood flow to the skin is cut preserving more to flow to the the muscles.
Why do more blood flow during exercise?
Because during exercise more oxygen is required , so more blood is pumped to meet the requirement.
Why do peoples heart rates increase when exercising?
During vigorous exercise the heart is moving more oxygenated blood into the muscles, so it has to pump faster.
What happens to the heart when you exercise?
Muscles need more oxygen and glucose during exercise.They dilate their arteries to receive more blood . At the same time,working muscles push more blood in the veins to the heart.This increases the volume of blood reaching the heart.The heart therefore has to pump harder and faster.
