Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does the lymphatic system help maintain homeostasis?
A
It returns lost fluids to the circulatory system to maintain blood volume and pressure
B
It pumps blood throughout the body
C
It aids in gas exchange with the lungs
D
In moves the skeletal muscles
Explanation: 

Detailed explanation-1: -Your lymphatic system has many functions. Its key functions include: Maintains fluid levels in your body: As just described, the lymphatic system collects excess fluid that drains from cells and tissue throughout your body and returns it to your bloodstream, which is then recirculated through your body.

Detailed explanation-2: -The primary function of lymphatic vasculature is to maintain interstitial fluid homeostasis. Lymphatic vessels absorb fluids that extravasate from blood vessels and return them to blood circulation. In addition, lymphatic vessels absorb digested lipids from the intestine and regulate inflammation.

Detailed explanation-3: -As the interstitial fluid begins to accumulate, it is picked up and removed by tiny lymphatic vessels and returned to the blood. As soon as the interstitial fluid enters the lymph capillaries, it is called lymph. Returning the fluid to the blood prevents edema and helps to maintain normal blood volume and pressure.

Detailed explanation-4: -It leaks out of the capillary walls because of pressure exerted by the heart or osmotic pressure at the cellular level. As the interstitial fluid accumulates, it is picked by the tiny capillary lymphatics, passes through the lymph nodes, and finally returns the fluid to the venous circulation.

Detailed explanation-5: -There are two major functions of the lymphatic system. The first is to drain interstitial fluid and maintain the fluid balance between blood and tissue fluid. The second is to fight infection and mediate immunity.
