Cardiorespiratory System

The primary function of the cardiovascular system is to transport oxygen and nutrients to the tissues/cells of the body and to remove ___________________ and other waste products.

Vessels that return the oxygen-depleted blood back to the heart.

• Arteries

• Veins

• Capillaries

Vessels that carry the oxygen-rich blood to the vital organs and working muscles.

• Arteries

• Veins

• Capillaries

Small vessels that exchange blood between arteries, body organs (muscles), and veins.

• Arteries

• Veins

• Capillaries

The total volume of blood that is pumped by the heart per minute.

• Heart Rate (HR)

• Stroke Volume (SV)

• Cardiac Output (Q)

The number of beats of the heart per minute.

• Heart Rate (HR)

• Cardiac Output (Q)

• Stroke Volume (SV)

The amount of blood ejected from the left ventricle of the heart with each beat.

• Heart Rate (HR)

• Stroke Volume (SV)

• Cardiac Output (Q)

The measure of the pressure, or resistance to blood flow, within the arterial vascular system. Expressed in mmHG

• Stroke Volume

• Blood Pressure

• Oxygen Extraction

The pressure against the arterial wall during the left ventricle contraction.

• Systolic Blood Pressure

• Diastolic Blood Pressure

The pressure against the arterial walls during the relaxation phase of the heart contraction cycle.

• Systolic Blood Pressure

• Diastolic Blood Pressure
