hello friend,

We all know that whenever we take oxygen through our lungs to the heart, the heart filtrate the harmful oxygen into useful.

After filtration oxygen is used for making and in the help of other organs.After formation of blood Arteries carry the blood from the heart to all the parts and organs of the body which needs blood for their function Arteries supplies blood to them.

Then what is the function of Veins. The function of Veins is to carry the impure blood from all the organs of the body to the heart for the process of filtration.

This means Arteries carry the Deoxygenated blood from the body and Veins carry the Oxygenated blood to the body.

The circulatory system includes the combined functioning of the heart,blood and blood vessels to deliver oxygen and other nutrients to the different parts and organs system and also tissues of the body and to remove waste products from the blood of the body.

The lymphatic system is composed of an intricate system of lymphatic vessels and lymphatic tissues including lymph nodes,spleen and thymus. The main purpose of lymphatic vessels is to absorb and return lymph fluid from the body.

Capillaries are the smallest link between the Arteries and veins and this capillaries are formed by small Arteries called arterioles branching out to become progressively smaller in diameter.The thin wall of the capillaries enables an exchange of oxygen and nutrients into the body tissues and absorption of carbon dioxide and waste products back into the circulatory system.

The lymphatic system is closely associated with the blood system and represent an accessory route by which lymph fluid can flow from the body's tissues back into the blood stream.

Lymph vessels can be categorized into lymph capillaries,precollectors, lymph collectors and lymphatic trunk.Lymph capillaries represent the beginning of the lymphatic drainage system and originate in close proximity to blood capillaries.Lymph capillaries resemble blood capillaries but have a more irregular structure and their walls are more permeable than those of blood capillaries.

Because of their unique structure, lymph capillaries are able to absorb larger particles from the tissues, such as protein, cells, bacteria and other large substance, which cannot be absorbed by the blood capillaries.

On its way back to the blood lymphatic fluid travels through a successive number of lymph nodes, which filters out impurities from the lymph.

................I hope it will helps you............

jyoti155: but I think that artery carries the oxygenated blood and the vein carries oxygenated blood
jyoti155: It may be that it is misprint in the diagram
