In humans, what does the normal systolic and diastolic blood pressure mean?
The cardiac cycle includes everything except
Ventricular systole
Atrial systole
Angina pectoris
Atrial diastole
How is systemic vascular resistance determined?
- Blood pressure inside the artery during contraction is systolic pressure.
- Blood pressure inside the vein during relaxation is diastolic pressure.
- Normal diastolic pressure is 120 mm of Hg.

- Atria contract
- Ventricles contract
- Atria relax
- Ventricles relax
- systole of the left atrium
- diastole of the right ventricle
- systole of the left ventricle
- diastole of the right atrium
- 120 /80 = 1.5 mm Hg
- 120 * 80 = 9600 mm Hg
- 120 + 80 = 200 mm Hg
- 120 - 80 = 40mm Hg
- Atria systole
- Atria diastole
- Ventricle diastole
- Ventricle systole

returns to the heart
enters the heart
- Both ventricles
- Left ventricle
- Right ventricle
- Both atria
- The relaxation period after contraction of the heart
- The number of heart beats per minute
- The contraction period after relaxation of the heart
