Answer & Solution
Correct Answer
(A) Tunica media
Step-by-step Solution
Detailed explanation
Opening of coronary sinus is guarded by Thebesian valve. Semilunar valves are present at the base of systemic aorta and pulmonary aorta. Mitral valve is also known as left atrioventricular or bicuspid valve. Opening of inferior vena cava is guarded by Eustachian valve.

- Two identical long parallel wires carry currents ' \(\mathrm{I}_1\) ' and ' \(\mathrm{I}_2\) ' such that \(\mathrm{I}_1>\mathrm{I}_2\). When the currents are in the same direction, the magnetic field at a point midway between the wires is \(8 \times 10^{-6} \mathrm{~T}\). If the direction of \(\mathrm{I}_2\) is reversed, the field becomes \(3.2 \times 10^{-5} \mathrm{~T}\). The ratio of \(\mathrm{I}_2\) to \(\mathrm{I}_1\) isMHT CET 2025 Medium
