What is a normal venous return of blood flow?

In a resting individual, the average venous return is approximately 5 liters of blood per minute. This value can fluctuate depending on factors such as physical activity or medical conditions.

What is an antagonistic hormone to actions of aldosterone?
The hormone that antagonizes the actions of aldosterone is atrial natriuretic peptide (ANP). ANP inhibits aldosterone secretion and activity, promoting salt and water loss by the kidneys, which helps to reduce blood pressure and blood volume.
What actions allow blood to return to the heart?
The blood is able to move to and from the heart through the contraction of the heart muscle. These contractions build up pressure and cause you to have what is commonly known as blood pressure. That build up of pressure pushes the blood throughout the arteries and veins and enables it to circulate throughout the body.
Do capillaries have non return valves?
No, capillaries do not have non-return valves. Non-return valves are found in veins to prevent blood from flowing backwards. Capillaries function to allow the exchange of nutrients and waste products between blood and tissues.
How do the valves within the veins of the arms and legs help blood return to the heart?
