Cross sectional area of veins is four times that of arteries This large cross sectional area plus large degree of compliance (yielding to pressure) implies that large amounts of blood can be stored in the veins with only minimal increase in pressure.
Veins have ability to store blood but arteries not so they are more some for blood storage and some for blood transport to right arteria.
No, renal veins carry blood that has been filtered by the kidneys to remove waste products, excess ions, and water. This filtered blood is then returned to the circulatory system to be recirculated through the body.
yes
While at rest, the greatest quantity of blood will be found in the veins, as they hold about 70% of the total blood volume in the body. This is due to the veins being able to store more blood and their compliance allowing them to hold a higher volume of blood at rest.
Extra blood is stored in the venous system, particularly in the veins of the liver, skin, and spleen. The liver acts as a blood reservoir due to its high vascularity and ability to store and release blood as needed. The skin also serves as a blood reservoir, with capillaries and venules able to hold excess blood. Additionally, the spleen can store blood in its sinuses and release it into circulation when necessary.
Elevating your legs can help alleviate discomfort from varicose veins by reducing swelling and improving blood flow. When you elevate your legs, gravity helps to drain excess blood and fluid from the veins, decreasing pressure and discomfort in the affected area.
yes - it means that they store/hold a lot of blood.

Veins
Veins return blood to the heart.The pulmonary veins.
Varicose veins form when blood pools in the veins.
Elevating your legs can help alleviate symptoms of varicose veins by reducing swelling and improving blood flow. When you elevate your legs, gravity helps to drain excess blood from the veins, reducing pressure and discomfort in the affected area. This can help to alleviate symptoms such as pain, swelling, and heaviness associated with varicose veins.
