Cardio-Vascular system

The smallest blood vessels are the

• arteries

• arterioles

• capillaries

• veins

Blood flows fastest in the

• Arteries

• Capillaries

• Veins

• Venules

The right atrium

• delivers deoxygenated blood to the lungs

• delivers oxygenated blood to the body

• receives deoxygenated blood from the body

• receives oxygenated blood from the lungs

Blood from the LEFT ventricle goes to the

• aorta

• left atrium

• right atrium

• left ventricle

The valves in the veins are to

• control blood flow

• divert blood to different areas

• prevent backflow

• regulate blood pressure

The atria (two atriums) in the heart have what function?

• collect in-coming blood

• restrict blood flow

• send blood out of the heart

• none of these

Blood under the highest pressure will be found in the

• arteries

• capillaries

• veins

• they are all the same

The ________________ pumps blood throughout the entire body.

• Liver

• Brain

• Heart

• Lungs

A systematic blood pressure reading always consists of two numbers, which are called:

• systemic/systolic

• systolic/diastolic

• diastolic/systolic

• diastolic/systemic

Separates the chambers of the heart.

• mitral valve
• septum
• aortic valve
