Question

Give the functions of lymph? Differentiate between blood and lymph.

Answer 1

Blood and lymph are two types of circulatory fluids in our body. Blood circulates through the circulatory system, while lymph flows in the lymph system. Lymph is produced by interstitial fluid obtained from thin capillary ends in the intercellular spaces after blood is fenestrated.

Complete answer: Lymph performs a variety of essential roles. Few main lymph features are listed below:
It keeps the cells of the body moist.
It brings oxygen, hormones, and nutrients to various parts of the body and eliminates the metabolic waste from the cells.
It carries antibodies and lymphocytes to the blood.
Maintaining the composition of skin fluid and blood volume.
Absorption of fat from the small intestine by lymphatic vessels.
Prevents the invasion of bacteria and foreign substances in lymph nodes.
The differences are as follows:

Blood	Lymph
Blood is reddish in colour due to the presence of haemoglobin	It is colourless or slightly white in colour and lacks haemoglobin.
It passes into the blood vessels	It passes into lymph vessels
It consists of plasma, RBC, WBC and platelets.	It consists primarily of WBC and platelets.
It is intended for the exchange of gases such as oxygen, carbon dioxide, etc., nutrients, hormones, waste products, etc.	Its primary function is in the defence mechanism of our body.
The two connective tissue is accomplished in proteins such as albumin, globulin, etc., minerals and enzymes	The plasma of lymph no longer comprises huge protein molecules and minerals.
Its movement is swift and bi-directional	Its movement is slow.

Note: The number of WBCs in the lymph is comparatively smaller. It consists mainly of lymphocytes intended for defence mechanisms. It brings dead and rotting waste, contaminants and pathogens to lymph nodes for death.
