Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following describes the physiological relationship between blood capillaries and lymph capillaries?
A
Lymph capillaries meander around blood capillaries
B
Lymph capillaries absorb excess interstitial fluid leaking from blood capillaries and return it to the venous system
C
Lymph capillaries absorb excess interstitial fluid leaking from blood capillaries and return it to the arterial system
D
Blood capillaries absorb excess interstitial fluid leaking from Lymph capillaries and return it to the arterial system
E
Blood capillaries absorb excess interstitial fluid leaking from Lymph capillaries and return it to the venous system
Explanation: 

Detailed explanation-1: -Blood vessels deliver oxygen and nutrients to virtually all cells in developing mammalian embryos and adults, whereas lymphatic vessels drain the interstitial fluid that collects in tissues, and serve as a conduit for immune cell trafficking and fat absorption.

Detailed explanation-2: -The lymphatic system (lymph, lymph nodes and lymph vessels) supports the circulatory system by draining excess fluids and proteins from tissues back into the bloodstream, thereby preventing tissue swelling.

Detailed explanation-3: -Simply speaking, the difference between blood and lymph is that lymph, unlike blood, is colourless and it is a return fluid from tissues to the central circulation. Furthermore, interstitial fluid is present between the cells in the various tissues and it enters the lymph capillaries.
