Question:
Assertion (A): Albumin regulates colloidal osmotic pressure of blood.
Reason (R): Heparin is the blood clotting protein.
Assertion (A): Albumin regulates colloidal osmotic pressure of blood.
Reason (R): Heparin is the blood clotting protein.
Reason (R): Heparin is the blood clotting protein.
Show Hint
Albumin maintains osmotic balance; heparin prevents coagulation.

- Both A and R are true and R is the correct explanation of A
- Both A and R are true but R is not the correct explanation of A
- A is correct but R is wrong
- A is wrong but R is correct
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand Albumin function.
Albumin is the most abundant plasma protein in blood and is responsible for maintaining colloidal osmotic pressure.
Step 2: Role of osmotic pressure.
It helps in retaining water within blood vessels and maintains fluid balance between blood and tissues.
Step 3: Evaluate Reason (R).
Heparin is not a blood clotting protein; instead, it is an anticoagulant that prevents blood clotting.
Step 4: Identify correct clotting factors.
Blood clotting involves fibrinogen, prothrombin, and other clotting factors, not heparin.
Step 5: Analyze relationship.
Since R is incorrect, it cannot explain A.
Step 6: Conclusion.
A is correct but R is wrong.
