HBS Quiz 19 Unit 4 circulatory system, Cardiac Output, He

The large arterial trunk that carries blood from the heart to be distributed by branch arteries through the body

• Aorta

• Arteriole

• Artery

• Atrium

A chronic disease characterized by abdominal thickening and hardening of the arterial walls with resulting loss of elasticity

• Arteriosclerosis

• Atherosclerosis

• Atriumosclerosis

• Cappillarosclerosis

Striated muscle fibers (cells) that form the wall of the heart; stimulated by the intrinsic conduction system and autonomic motor neurons is called....

• Cardiac muscle

• Atrium muscle

• Smooth muscle

• Circulation muscle

A measure of cardiac activity usually expressed as number of beats per minute

• Heart rate

• Cardiac output

• Blood pressure

• Arteriole rate

Vascular disease affecting blood vessels outside of the heart and especially those vessels supplying the extremities

• Peripheral vascular disease

• Peripheral artery disease

• Pulmonary vascular disease

• Coronary Artery disease

A regularly recurrent wave of distension in arteries that results from the progress through an artery of blood injected into the arterial system at each contraction of the ventricles of the heart

• Pulse

• Heart rate

• Circulation

• Cardiac output

A chamber of the heart which receives blood from a corresponding atrium and from which blood is forced into arteries

• Ventricle

• Venule

• Vein

• Valve

What types of muscle help move blood around the body?

• The heart is the primary muscle that helps move blood & is made of cardiac muscle tissue. It is responsible for the circulation of blood & all the materials in it.

• The heart and lungs work together to get oxygen to the tissues. The heart pumps the blood, and the lungs put oxygen into it. This oxygen-rich blood then circulates throughout the body to nourish the cells; oxygen-depleted blood gets collected from the tissues to be oxygenated in the lungs

• The right side of the heart collects deoxygenated blood into its atrium & then passes it into the ventricle. The right ventricle then pushes the blood to the lungs, where the CO2 is dropped off and O2 is picked up.

• Three layers of thick, fairly rigid walls to allow them to expand/contract & to handle high pressure (blood has greatest pressure as it's leaving the heart)— one layer is smooth muscle

What is the relationship between the heart and the lungs?

• The heart is the primary muscle that helps move blood & is made of cardiac muscle tissue. It is responsible for the circulation of blood & all the materials in it.

How do the structure of arteries relate to their function in the body?

• The heart is the primary muscle that helps move blood & is made of cardiac muscle tissue. It is responsible for the circulation of blood & all the materials in it.

• The heart and lungs work together to get oxygen to the tissues. The heart pumps the blood, and the lungs put oxygen into it. This oxygen-rich blood then circulates throughout the body to nourish the cells; oxygen-depleted blood gets collected from the tissues to be oxygenated in the lungs
