We distinguish between the superficial and the deep venous systems. Your venous system is a network of veins that carry blood back to your heart from other organs.

Arteries are the strongest thickest and most elastic of all the vessels.
Anatomy of venous system. Blood is the transport media of nearly everything within the body. Anatomy of the venous system the venous system is that part of the circulation in which the blood is transported from the periphery back to the heart. This system contains two fluids blood and lymph and functions by means of two interacting modes of circulation the cardiovascular system and the lymphatic system.
The anatomy and physiology of venous return are described with an emphasis on the differences between standing and walking and the interplay between the venous systems of both the foot and the calf. The physiology of venous return. When these systems are infected with a microorganism the network of vessels can facilitate the rapid dissemination of the microorganism to other regions of the body sometimes with serious results.
They are an important part of the calf muscle pump mechanism see ch. The arteries divide into smaller vessels called arterioles. The paired veins join into common trunks in the upper calf before forming the below knee popliteal vein.
As arterial blood flows into the leg distal superficial veins constantly fill venous blood is regularly emptied from the superficial system into the deep venous system via the sfj spj and perforators this blood is then returned to the right side of the heart through one way valves by calf muscle contraction. Both the fluid components and the vessels through which they flow reach their greatest elaboration and specialization in the mammalian systems and particularly in the human body. The soleal veins are deep venous sinuses and veins of the soleus muscle that drain into the popliteal vein.
They carry the blood at high pressure away from the heart. The circulatory and lymphatic systems are networks of vessels and a pump that transport blood and lymph respectively throughout the body. It transports hormones nutrients oxygen antibodies and other important things needed to keep the body healthy.
Veins carry deoxygenated blood to the lungs where they receive oxygen. Aorta is the largest artery.
