Question

The important function of lymph is to
(a)Transport of oxygen to the brain
(b)Transport carbon dioxide to the lungs
(c)Return RBCs to the lymph nodes
(d)Return interstitial fluid to the blood

Answer 1

Hint: The immune cells are produced by the lymph and play an important role in nutrient transport and toxin elimination in our body.

Complete step-by-step answer:
There are several functions of the lymph but one of the key roles of it is to return the interstitial fluid to the blood. Lymph is the fluid part of the plasma as well as WBC.
The extracellular fluid (the fluid that is present outside the cell) is divided into the interstitial fluid (the fluid which is present between the tissues) and the plasma. Both plasma, as well as the interstitial fluid, are the same due to the constant exchange of several small solutes, ions, and water through the capillary walls of the tissues. The interstitial fluid will be collected by the lymphatic system and the remaining will get drained out. The drained fluid will move back to the blood vessels and the residual fluid will be collected via the capillaries of lymph.
Lymph is a fluid that is the pale white fluid that will circulate all over the lymphatic system. It will filter various microorganisms and organic wastes.
The key functions of lymph are:
-It helps in transporting oxygen, nutrients, and hormones to other body parts. Furthermore, it eliminates metabolic wastes present in the cell.
- Lymph transports antibodies and the lymphocytes to blood.
-Prevents the entry and the attack of microbes and allergens in the lymph node.
-It maintains the cells in moist conditions.
So, the correct answer is ‘Return interstitial fluid to the blood’.

Note: We all know that the lymph system carries away the microorganisms and other toxins from our body. Exercise, breathing exercise, drinking plenty of water, alternative hot and cold baths, avoiding tight dress and eating foods that will enhance the lymph flow are some of the steps that can be followed to keep our lymph system clean.
