Who is it important that the lymphatic system operate separa

Solution

It is important that the lymphatic system operate separately from the cardiovascular system becuase lymphatic system is a closed circulatory system that consists of lymph capillaries, lymph vessels, and lymph nodes different to blood vessels. The lymph present in capillaries flows into lymphatic vessels, which are presented deep or superficial but blood vessels are deep innervating various parts of body to maintain pheripheral resistance & mean arterial blood pressure. Blood flows through three types of blood vessels (arteries, capillaries and veins) distributed throughout the body. Capillaries are the fine endings of blood vessels. These capillaries are responsible for the exchange of respiratory gases, nutrients and waste products. The molecules move across the capillaries through a process called “diffusion.” These lymph vessels combine to form lymphatic trunks that empty into the large collecting vessels of lymphatic system called “thoracic duct and right lymphatic duct.”

The lymphoid tissue is mostly composed of a reticular connective tissue (a type of loose connective tissue). The fibres of the reticular network contain macrophages. A number of lymphocytes from the postcapillary venule walls occupy this network and leave to the body again. This ensures the lymphocytes to identify the infected sites at a faster rate.

Lymphatic system is a closed circulatory system that consists of lymph capillaries, lymph vessels, and lymph nodes. Lymph is a tissue fluid, which is formed by the diffusion of substances from blood capillaries into tissue spaces. The lymph present in capillaries flows into lymphatic vessels, which are presented deep or superficial. These lymph vessels combine to form lymphatic trunks that empty into the large collecting vessels of lymphatic system called “thoracic duct and right lymphatic duct.”

It is important that the lymphatic system operate separately from the cardiovascular system due to the follwoing reasons and exerts differentail effects of innate immune system. The lymph is generated to produce defensive mechanisms via innate immunity include physical barriers, phagocytes, immune surveillance,interferons, complement system, inflammation and fever.

1. Fluid recovery: Filtration of the fluid into the tissue spaces from the blood capillaries will occur continuously. 85% of it will be absorbed by the blood capillaries. About 15% will be remained unabsorbed. This unabsorbed portion of the fluid is about 2-4 litres of water and 1/4^th to 1/2th of plasma protein. If this water protein and water does not reach the bloodstream, then the patient will die of circulatory failure. Lymphatic system will collect this excess fluid and return it to the blood stream.

2. Immunity: Lymphatic system will carry the excessive fluid from the tissue spaces. Along this fluid microorganism and pathogens will also enters the lymphatic system. This fluid will pass through the lymph nodes, where immune cells are present, which will activate the immune response against these pathogens.

3. Lipid absorption: Lacteals are the special lymphatic vessels present in the small intestine. These lacteals will absorb the lipids, which cannot be absorbed by the intestinal blood capillaries.
