Question

Interstitial fluid is called tissue fluid
(a) True
(b) False

Answer 1

Hint: Interstitial fluid serves as a reenergizing center for cells as they provide nutrients for metabolism. Interstitial fluid is rich in glucose, ions, amino acids, and other minerals like calcium, potassium, and magnesium.

Complete answer:
The watery fluid that surrounds the cells, interchange of substances among the blood and tissue. Oxygen, carbon dioxide, amino acids, ions, salts, and waste products are the substances that are exchanged from blood tissues and tissues to the blood which is why it is called tissue fluid.

Additional information:
- The nutrients and minerals of the interstitial fluid is derived from the capillaries of blood. It can also sustain waste materials that are produced by metabolism.
- In a healthy adult's body the total water percentage is around a range of $50\% - 70\%$ of the complete body weight.
- Of all this, the interstitial fluid makes up almost one- third of the total fluid percentage, the intracellular fluid makes up two- thirds which is present inside the cells. The interstitial fluid is also a major component of extracellular fluid.
So the correct answer is ‘(a) True’.

Note:
- For diabetic patients, Continuous glucose monitors (CGM) can be used to analyze the glucose level of interstitial fluid by inserting a small sensor beneath the skin.
- Time to time, these sensors will read the glucose content present in the interstitial fluid and help in recording and monitoring the readings.
- Solid or semisolid substances that are secreted from the cells, other cellular components that are soluble substances along with dissolved oxygen and carbon dioxide, nutrients, and ions constitute interstitial fluid and helps the cells to maintain life.
