State the major body systems that respond immediately to the transition from rest to exercise.

• Cardiovascular, skeletal and muscular

• Respiratory, skeletal and muscular

• Cardiovascular, respiratory and muscular

• Cardiovascular, digestive and nervous

Cardiac output is the product of which two factors?

• A. Heart rate and stroke volume

• B. Blood volume and heart rate

• C. Tidal volume and heart rate

• D. Stroke volume and blood volume

The pressure exerted by the blood against the arterial walls as it is forced through the circulatory system by the action of the heart is called:

• Blood Pressure

• Heart Rate

• Cardiac Output

• Stroke Volume

The amount of blood ejected from the left ventricle of the heart per minute is known as:

• Stroke Volume

• Cardiac Output

• Heart Rate

• Blood Pressure

What is the blood pressure recorded during the relaxation phase of the heart cycle?

• Systolic pressure

• Diastolic pressure

• Pulse pressure

• Mean arterial pressure

What is the movement of oxygen and carbon dioxide from areas of high concentration to areas of low concentration between the alveoli and the surrounding capillaries?

• Diffusion

• Osmosis

• Active transport

• Facilitated diffusion

The amount of blood ejected from the left ventricle with each beat (contraction) of the heart is called:

• Stroke Volume

• Cardiac Output

• Heart Rate

• Blood Pressure

What is the blood pressure recorded as blood is ejected during the contraction phase of the heart cycle?

• Systolic blood pressure

• Diastolic blood pressure

• Mean arterial pressure

• Pulse pressure

The amount of air inspired and expired by the lungs per breath is called:

• Tidal Volume

• Residual Volume

• Vital Capacity

• Total Lung Capacity

What is the process where blood vessels narrow or constrict as a response to a decreased demand for oxygen delivery to muscle tissue?

• Vasodilation

• Vasoconstriction

• Hyperemia

• Angiogenesis
