Question

Tissue fluid is also known as
A. Extracellular fluid
 B. Intracellular fluid
 C. Both A and B
 D. None of the above

Answer 1

Hint: Presence of water, amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, and cellular products in the case of the interstitial fluid. The main constituent of fluid outer to the cell is the interstitial fluid that surrounds the cell externally.

Complete answer:
Interstitial fluid is the fluid that fills the intercellular spaces. The main constituent of extracellular fluid is the interstitial fluid that surrounds the cells of the body. The main constituent of ECF is the intravascular fluid in the circulatory system called plasma of the blood.

Additional information: Fluid found in the spaces around cells. It comes from substances that leak from the blood capillaries (the smallest type of blood vessel). Helps transport oxygen and nutrients to cells and remove wastes from them. As new tissue fluid is produced, it replaces the old fluid that drains in the lymphatic vessels. After entering the lymphatic vessels, it is known as lymph. It is also known as interstitial fluid.
So, the correct option is ‘ C. Extracellular fluid and Intracellular fluid’.

Note: Lymph is a fluid formed by the immune system that consists of white blood cells that fight off infectious substances that have moved into the body. The meaning of Extracellular outside the cells. Lymph is extracellular as the fluid is traveled outside the cell but not inside the cells. Extracellular fluid (ECF) refers to all fluids of the body external to the cells of any multicellular organism. Total body water in healthy adults is approximately 60% (range 45-75%) of total body weight; women and obese people tend to have a lower percentage than thin men. Citation needed.
