Name the blood cells, whose reduction in number can cause clotting disorder, leading to excessive loss of blood from the body.

A Erythrocytes
B Leucocytes
C Neutrophils
D Thrombocytes

Verified Solution

Answer & Solution

Correct Answer

(D) Thrombocytes

Step-by-step Solution

Detailed explanation

(d) : Thrombocytes are called blood platelets. They are minute discshaped cell fragments in mammalian blood. They are formed as fragments of larger cells found in red bone marrow; they have no nucleus. They play an important role in blood clotting and release thromboxane \(A_2\), serotonin and other chemicals, which cause a chain of events leading to the formation of a plug at the site of the damage, thus preventing further blood loss. A reduction in their number can lead to clotting factors which will lead to excessive loss of blood from the body.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
