When the heart pumps blood around the body it makes more blood available to all parts of the body, including the muscles

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.
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
Does increasing arterial blood pressure increases blood flow?
YES! Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end - diastolic pressure and volume. This increase in ventricular preload increases ventricular stroke volume by the Frank - Starling mechanism. An increase in right ventricular stroke volume increases pulmonary venous blood flow to the left ventricular, thereby increasing left ventricular preload and stroke volume. An increase in stroke volume then increases cardiac output and arterial blood pressure. answered by HappyNess0423
Why increasing the size of the afferent arteriole increase volume of filtrate and rate filtration?
It increases the volume of blood at filtration site , increases the filtration gradient, and increases time of contact of blood with filtration site.
Increased blood volume?
Endurance exercise, such as jogging, swimming and cycling, increases your blood volume over time.
What are the effects of the aerobic training on blood?
Aerobic training increases the volume of blood in the body.
Why do athletes have a higher cardiac output?
regular aerobic exercise strengthens heart muscles which increases stroke volume (the volume of blood ejected with each contraction). since cardiac output = stroke volume * heart rate, this ultimately increases cardiac output.
What can cause hyperemia?
Hyperemia can be caused byaldosterone hormone (which increases blood volume, therefore, icreases blood pressure). Either way by physical exercise -when someone is training,working out- which activates sympaticus and parasympaticus.
Why do red blood cells take oxygen to the working muscles?
Red Blood cells take oxygen to the working muscles as it is required for respiration.
What do red blood cells carry to the working muscles?
Oxygen
What is the rationale for reducing dietary salt for patients with high blood pressure?
Salt which is taken in by the body into the blood, causes the water in the body to follow salt into the blood vessels. This increased uptake of water into the circulatory system increases the volume of blood in the blood vessels. This increased volume increases blood pressure.
What happens to blood pressure when the smooth muscle of an arteriole contracts?
When the radius of the smooth muscle decreases the pressure increases. So the blood pressure becomes higher
