Question

Pressure exerted by blood against the walls of an artery during ventricular expansion is
A. Systolic Pressure
B. Ventricular Pressure
C. Both A and B
D. Cardiac output

Answer 1

Hint The circulatory system, also known as the cardiovascular or vascular system, is an organ system that allows blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the body's cells to provide nourishment, aid in disease prevention, and maintain homeostasis.

Complete answer: The action of the pumping heart pushes blood through the body. Blood is pushed away from the heart at high pressure and velocity with each rhythmic pump, initially along the main artery, the aorta. Blood moves at 30 cm/sec through the aorta.
The pressure exerted by blood on the walls of a blood vessel that helps to push blood through the body is known as blood pressure (BP). The amount of pressure that blood exerts on vessels while the heart is beating is measured by systolic blood pressure. The ideal systolic blood pressure is 120 millimeters of mercury.
The systolic pressure (the higher pressure and the first number recorded) is the force that blood exerts on artery walls as the heart contracts to pump blood to the peripheral organs and tissues, and the diastolic pressure (the lower pressure and the second number recorded) is the residual pressure exerted on the arteries as the heart relaxes.
During left ventricular contraction, blood is pushed into the aorta by the pressure exerted on the arterial wall. This is referred to as ventricular systole or ventricular pressure. The first heart sound, lubb, is produced when the atrioventricular valves close during ventricular systole.

As a result, B is the correct answer.

Note: In vertebrates, blood circulation has evolved differently, and the required amount of pressure, organ and vessel location, and organ size may vary depending on the animal. Long-necked animals and those who live in cold climates have different blood pressure adaptations.
