The average blood volume of adults is about ... litres?
ব্যাখ্যা
The average blood volume of adults is about 7% of body weight, or about 5 litres. About 60% of the blood is plasma and 40% is red blood cells, but these percentages can vary considerably in different people, depending on sex, weight, and other factors.

Dehydration increases the plasma concentration of all the following hormones except -?
ব্যাখ্যা
ANP is called Hypervolemia hormone. It secretion increased during hypervolemia and decreased secretion during dehydration and volume depletion.

Tetany occurs when plasma calcium level falls below …mg/dl
ব্যাখ্যা
Hypoparathyroidism leads to hypocalcemia, by decreasing the resorption of calcium from bones. Hypocalcemia causes neuromuscular hyperexcitability, resulting in hypocalcemic tetany. Normally, tetany occurs when plasma calcium level falls below 6 mg/dL from its normal value of 9.4 mg/dL.
৯.
Thirst centre is stimulated by-?
ব্যাখ্যা
Thirst center is stimulated by-
-Intracellular dehydration
-Hypovolemia
-Angiotensin-2 in circulation
১০.
About what % of human body is fluid?
ব্যাখ্যা
60% of TBW is fluid where 40% is ICF & 20 is ECF
১১.
What is not the example of transcellular fluid-?
ব্যাখ্যা
Transcellular fluids are-
-CSF
-Synovial fluid
-Peritoneal fluid
-Pleural fluid
-pericardial fluid
-Intraocular fluid (Aqueous humor)
-Fluids in the lumen of GIT
-Fluid in lumen of nephron(urine)&Sweat
Oedema fluid is not transcellular fluid.
১২.
What is the basic differentiating point between plasma & ISF in case of composition?
ব্যাখ্যা
Interstitial fluid is three-fourths of the ECF. Thus, it is one-fourth of TBW. The composition of interstitial fluid is the same as that of plasma except that it has little protein. Thus, interstitial fluid is an ultrafiltrate of plasma.

২২.
Which of the following substances or combinations of substances could be used to measure interstitial fluid volume?
ব্যাখ্যা
Interstitial fluid volume is measured indirectly by determining the difference between extracellular fluid (ECF) volume and plasma volume. Inulin, a large fructose polymer that is restricted to the extracellular space, is a marker for ECF volume. Radioactive albumin is a marker for plasma volume.
২৩.
The percentage of TBW is highest in...
ব্যাখ্যা
Total body water (TBW) is approximately 60% of body weight. Body water is inversely proportional to body fat. The percentage of TBW is highest in newborns then in adult males and lowest in adult females and in adults with a large amount of adipose tissue.

Which of the following causes increased aldosterone secretion?
ব্যাখ্যা
Explanation-
★ Decreased blood volume stimulates the secretion of renin (because of decreased renal perfusion pressure) and initiates the renin–angiotensinaldosterone cascade. Angiotensin-converting enzyme (ACE) inhibitors block the cascade by decreasing the production of angiotensin II. Hyperosmolarity stimulates antidiuretic hormone (ADH) [not aldosterone] secretion. Hyperkalemia, not hypokalemia, directly stimulates aldosterone secretion by the adrenal cortex.
