Cardiac Cycle and Regulation

Opening of AV valves is caused by:

The correct answer is B: Atrial pressure > ventricular pressure. In Cardiac Cycle and Regulation, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, cause and effect line up with Atrial pressure > ventricular pressure — that is the mechanism or reason the stem is pointing to. That is why Atrial pressure > ventricular pressure is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Cardiac Cycle and Regulation

During isovolumetric relaxation, ventricular volume:

Pick C: Remains constant. Thinking about Cardiac Cycle and Regulation in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: Remains constant is the option that correctly names the structure, process, or principle asked for in Cardiac Cycle and Regulation. Hence Remains constant is correct. Treat this as a building block for the rest of Cardiac Cycle and Regulation; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.
