Yeah, I definitely recall that systole refers to the heart beating and diastole is when it relaxes. So, I think the answer is C.

I'm not entirely sure, but I feel like systole and diastole might have something to do with blood pressure readings too.

I remember practicing a question about the cardiac cycle, and I think systole is when the heart contracts.

I think systole and diastole are related to the heart, but I can't remember which part exactly.

Okay, let me think this through step-by-step. Systole and diastole... those sound like they have to do with the cardiovascular system. The options mention the heart, breathing, and immune function, so I'll focus on the heart-related choices. I'm going to go with option C, "Heart beat".

Ah, I remember learning about this in my biology class! Systole and diastole are the phases of the heart's pumping cycle. Systole is the contraction of the ventricles, and diastole is the relaxation and filling of the ventricles. I'm confident I can get this one right.

I'm pretty sure this has to do with the heart, since the options mention things like "breathing cycle" and "heart beat". I'll try to remember that systole and diastole refer to the contraction and relaxation phases of the heart.

Hmm, I'm a bit confused on this one. I know systole and diastole are medical terms, but I can't quite recall what they specifically refer to. I'll have to think this through carefully and try to eliminate the options that don't seem right.

I'm a little confused by the wording of this question. Let me think through the Chatter features and how they might apply to this scenario. I want to make sure I select the best option.
