WebJan 17, 2024 · Two mechanisms take place in the heart: diastole and systole. Diastole is the relaxation of the chambers of the heart and systole is the contraction of the heart chambers. Systolic pressure is thus the pressure that your heart emits when blood is forced out of the heart and diastolic pressure is the pressure exerted when the heart is relaxed. WebThe period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole. businesses in savoy ilhttp://ib.bioninja.com.au/standard-level/topic-6-human-physiology/62-the-blood-system/cardiac-cycle.html businesses in sanford fl
