CardioVascular Notes

Surrounded by ________, arterioles are the primary site of vascular resistance.

________: Specialized muscle tissue (cardiac muscle) that forms the heart.

________ are blood vessels that carry blood toward the heart.

________ is received into the atria and pushed out from the ventricles.

________: The smallest of the blood vessels, ________ help to enable the exchange of water, oxygen, carbon dioxide, and other nutrients and waste substances between the blood and the tissues of the body.

________ are blood vessels that carry blood away from the heart.

________: The low pressure within the veins causes a problem for the cardiovascular system.

________: The role of the left side of the heart is to pump oxygenated blood, which has just returned from the lungs to the rest of the body.

________: The main function of the right side of the heart is to pump deoxygenated blood, which has just returned to the body, to the lungs.

Blood is received

Plasma, White blood cells and red blood cells

Right Atrium, Tricuspid valve, Right ventricle, pulmonary valve, pulmonary arteries

Left atrium, mitral valve, left ventricle, aortic valve and aorta

Arterioles are vessels in the blood circulation system that branch out from arteries and lead to capillaries, where gas exchange eventually occurs

The smallest of the blood vessels, capillaries help to enable the exchange of water, oxygen, carbon dioxide, and other nutrients and waste substances between the blood and the tissues of the body

When blood pressure is reported or measured, it is often stated as being the systolic pressure over the diastolic pressure (e.g., 120/80 mmHg)

refers to the maximum pressure observed in the arteries during the contraction phase of the ventricle (e.g., 120 mmHg)

the minimum pressure observed in the arteries during the relaxation phase of the ventricle (e.g., 80 mmHg)

The cardiac cycle is a series of events that occurs through one heartbeat

The heart pushes oxygenated blood to the body and deoxygenated blood to the lungs. Blood flows from the heart through arteries and back to the heart through the veins.
