Show answer & explanation
Correct answer: A
Explanation
Diastolic Pressure -
The pressure in the arteries when the heart muscle relaxes between beats is called diastolic pressure.
Two Main Types of Blood Pressure:
A normal, healthy adult's blood pressure is usually 120/80 mmHg. Here's what these two numbers mean:
Systolic Pressure: This is the upper number (120). It is measured when the heart contracts and pumps blood into the arteries.
Diastolic Pressure: This is the lower number (80). It is measured when the heart muscle is relaxed and the heart is filling with blood.
A Brief Description of Other Options:
Venous Pressure: This is the blood pressure within the veins. It is much lower than arterial pressure.
Capillary pressure: It is the pressure inside the tiny blood vessels (capillaries), where nutrients are exchanged between the blood and tissues.
