Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).
Assertion (A): Albumin deficiency in plasma leads to the accumulation of fluid into the surrounding tissues, which is termed oedema.
Reason (R): Albumin is a plasma protein that regulates the movement of fluids between blood vessels and surrounding tissues and thus maintains osmotic balance.
In light of the above statements, choose the correct answer from the options given below.

Detailed Solution

Assertion (A) is true: Albumin deficiency in plasma can lead to the accumulation of fluid into the surrounding tissues, which is a condition termed oedema. Oedema occurs when the balance of fluid movement between blood vessels and surrounding tissues is disrupted, leading to excess fluid buildup in the tissues.
Reason (R) is true and provides the correct explanation for (A): Albumin is a plasma protein that plays a critical role in regulating osmotic balance. It maintains the osmotic pressure within blood vessels, which helps to retain fluid within the vessels. This osmotic pressure prevents excessive fluid from leaking out of blood vessels into the surrounding tissues. When albumin levels are low, the osmotic pressure decreases, causing fluids to move from blood vessels into the tissues, resulting in oedema.
(A) is true, and (R) is true, and (R) is the correct explanation for (A).
