Relaxation of heart is called systole/diastole.

Text Solution

AI Generated Solution

To answer the question "Relaxation of heart is called systole/diastole," we can follow these steps: ### Step-by-Step Solution: 1. **Understand Cardiac Cycle**: The cardiac cycle consists of two main phases: systole and diastole. Systole refers to the phase when the heart muscle contracts, while diastole refers to the phase when the heart muscle relaxes. 2. **Define Systole**: During systole, the heart contracts to pump blood out of the chambers (ventricles) into the arteries. This is the active phase of the heart cycle. ...

    Health Application A doctor reports blood pressure in millimetres of mercury (mm Hg) as a ratio of systolic blood pressure to diastolic blood pressure (such as 140 over 80). Systolic pressure is measured when the heart beats, and diastolic pressure is measured when it rests. Refer to the table of blood pressure ranges for adults. Manohar is a healthy 37 years old man whose blood pressure is in the normal category. Calculate ratio of average systolic to average diastolic blood pressure in the prehypertension category.

    The pacesetter in the heart is called

    The rhythmic expansion and contraction of the heart is called ______.

    The human ciculatory system can be thought of as a closed system of interconnecting pipes through which fluid is continuously circulated by two pumps the two pumps the right and left verticles of the heart, work as simple two-stroke force pumps. The muscles of the heart regulate the force by contracting and relaxing. the contraction (systole) lasts about 0.2s and a complete systole/diastole (contraction/relaxation) cycle lasts about 0.8s. For flood pressures and speeds in the normal range. the volume flow rate of blood through a blood vessel is directly proportional tot he pressure difference over a length of the vessel and to the fourth power of the radius of the vessel. The total mechanical energy per unit volume of blood just as it leaves the heart is E//V=rhogh+P+rhov^(2) Q. Why is diastolic blood pressure muchh lower than systolic pressure?
