At rest, not at all. BUT there would be less of an increase in cardiac output during exertion - which results in quick fatigue and lowered (maximum) activity.
Gravity slows down the return of blood to the heart.
The valves in veins assist blood is the movement of blood from the legs. This is slowed by gravity.
"The circulation of blood through the body is often compared to a plumbing system with the heart as the pump and the veins, arteries, and capillaries as the pipes through which the blood flows."
blood is pumped by a heart through vessels ....mean the volume of blood circulates faster (20 seconds in humans,
The part of the heart that opens when blood flows though is called the valve. There are four valves in the heart, two atrioventricular valves and two semilunar valves.
things that could affect the blood flow through the heart
upper chambers of the heart
the heart pumps through the through the body
moves from pulmonary veins to the left of the heart aorta
The pressure your heart creates by pulsing, pumps blood through the veins
it depends on the type of blood vessel if we say of veins so movement is in upward direction if we say about arteries so movement is downward.
Skeletal muscle movement and valves in the veins.
It's called the Circulation, as it is a flow from heart to lungs, back to heart, out around the body and back to the heart.
A normal echocardiogram shows a normal heart structure and the normal flow of blood through the heart chambers and heart valves
The Mitral Valve is in between the left atrium and the left ventricle of the heart. Oxygenated blood is pumped from left atrium to the left ventricle through that valve, mitral valve, then to the whole body through the Aorta artery. So problems with this valve may make the blood go back to the atrium during the contraction of the ventricle and this leads to decrease of the pressure of blood and the amount of it to the Aorta. This can affect the whole body.
contraction and relaxation of the heart muscles
whe blood go's through the heart it get oxganated
