Question

Why is systemic blood pressure (120/80 mmHg) different from glomerular hydrostatic pressure (60 mmHg)?

Answer 1

Systemic blood pressure is the pressure exerted by the blood on the arteries during its course. The above value indicates the pressure of blood during the systolic movement when the heart is contracted which is 120 mm Hg and the lower value represent the pressure of blood during the diastolic movement when the heart is relaxed which’s 80 mm Hg the high blood pressure makes the arteries less stretchy making it less expandable increasing the blood pressure during blood flow leading to deposit of fats and blocking the blood flow leading to heart.

Glomerular hydrostatic pressure is the pressure caused by glomerulus in the kidneys which lead to filtration of fluids like blood the more the pressure the more the filtration of blood and any pressure below the 60 mm Hg will might not caused effective filtration hence more pressure above 60 mm Hg is required.
