Question

lo 3.10. what does systolic blood pressure measure?
measures the heart rate.
measures the amount of oxygen in the blood.
measures the amount of blood that is being pumped by the heart during each contraction.
indicates how much pressure your blood is exerting against your artery walls when the heart contracts.
indicates how much pressure your blood is exerting against your artery walls when the heart relaxes.

Explanation:

Systolic blood pressure is related to the heart's contraction. When the heart contracts, it pumps blood out. The pressure exerted by the blood on the artery walls during this contraction is what systolic blood pressure measures. Heart rate is measured differently (e.g., beats per minute). The amount of oxygen in the blood is measured via oxygen - saturation tests. The amount of blood pumped per contraction is stroke - volume. And the pressure when the heart relaxes is diastolic blood pressure.

Indicates how much pressure your blood is exerting against your artery walls when the heart contracts.
