Question

Blood pressure will be maximum in ______.

• A. Efferent renal arteriole
• B. Coronary sinus
• C. Pulmonary trunk
• D. Renal artery

Hint:

Blood pressure is highest in arteries closest to the heart and lowest in veins.

Answer 1

The Correct Option is C

Step 1: Understanding blood pressure distribution.
Blood pressure is highest in large arteries receiving blood directly from the heart and decreases as blood flows through smaller vessels and veins.
Step 2: Analysis of given structures.
Efferent renal arteriole has regulated but not maximum pressure.
Coronary sinus is a venous structure with very low blood pressure.
Pulmonary trunk receives blood directly from the right ventricle, hence has relatively high pressure compared to veins and arterioles listed.
Renal artery has high pressure but lower than the main arterial trunk emerging from the heart.
Step 3: Conclusion.
Among the given options, the pulmonary trunk has the maximum blood pressure.
