Blood pressure in the mammalian aorta is maximum during
Blood pressure in the mammalian aorta is maximum during
Open in App
Solution
The correct option is A systole of the left ventricle
The temporary rise in blood pressure during the contraction of the heart is called systolic pressure and the temporary fall in blood pressure during relaxation of the heart is called diastolic pressure. Blood pressure is expressed as the ratio of the systolic pressure over the diastolic pressure. For a healthy resting adult person, the average systolic/ diastolic pressures are 120/180 mm Hg. Aorta is directly supplied by ventricle thus, the blood pressure in the aorta is highest during systole of the ventricle. During it, left ventricle contracts and pushes blood into the aorta.
