1

Stroke Volume

The amount of blood pumped out of the heart with each contraction

1

Respiratory System

A system of organs (the lungs and respiratory passageways) that collects oxygen from the external environment and transports it to the bloodstream

1

The inferior chambe of the heart hat receives blood from its corresponding atrium and, in turn, forces blood into the arteries

Ventricle

2

Atrioventricular (AV) Node

A small mass of specialized cardiac muscle fibers, lovated in the wall of the right atrium of the heart, that receives heartbeat impulsesfrom the sinoatrial node and directs them to the walls of the ventricles

3

Atrium

The superior chamber of the heart that recieves blood from the veins and forces it into the ventricles

3

Vessels that transport blood from the capillaries toward the heart

Veins

4

Blood

Fluid that circulates in the heart, arteries, capillaries, and veins, carries nutrients and oxygen o all parts of the body, and also rids the body of waste products

4

Small terminal branches of an artery, which end in capillaries

Arterioles

5

The process of actively or passively relaxing the inspiratory muscles to move air out of the body

Expiration

6

Heart Rate (HR)

The rate at which the heart pumps

6

Blood Vessels

Network of hollow tubes that circulates blood throughout the body

6

The smallest blood vessels, and the site of exchange of chemicals and waer between the blood and the tissues

Capillaries

7

A system of the body composed of the cardiovascular and respiratory systems

Cardiorespiratory System

9

Cardiac Output (Q)

Heart rate X stroke volume, the overall performace of the heart

11

Cardiovascular System

A system of the body composed of the heart, blood, and blood vessels

12

Sinoatrial (SA) Node

A specialized area of cardiac tissue, located in the right atrium of the heart, which initiates the electrical impulses that determine the heart rate; often termed the pacemaer of the heart

12

Venules

The very small veins that connect capillaries to the larger veins

12

Vessels that transport blood away from the heart

Arteries

13

The superior chamber of the heart that recieves blood from the veins and forces it into the ventricles

Atrium

13

Heart rate X stroke volume, the overall performace of the heart

Cardiac Output (Q)

14

Arterioles

Small terminal branches of an artery, which end in capillaries

15

A small mass of specialized cardiac muscle fibers, lovated in the wall of the right atrium of the heart, that receives heartbeat impulsesfrom the sinoatrial node and directs them to the walls of the ventricles

Atrioventricular (AV) Node

16

The space in the chest between the lungs that contains all the internal organs of the chest except the lungs

Mediastinum

17

The highest rate of oxygen transport and utilization achieved at maximal physical exertion

Maximal Oxygen Consumption (VO2max)

18

The very small veins that connect capillaries to the larger veins

Venules

26

The proces of getting oxygen from the environment to the tissues of the body

Diffusion

28

Maximal Oxygen Consumption (VO2max)

30

Veins

Vessels that transport blood from the capillaries toward the heart

32

Capillaries

The smallest blood vessels, and the site of exchange of chemicals and waer between the blood and the tissues

33

Heart

A hollow muscular organ that pumps a circulation of blood through the body by means of rhythmic contraction

34

Inspiration

The process of actively contracting the inspiratory muscles to move air into the body

35

Network of hollow tubes that circulates blood throughout the body

Blood Vessels

36

Diffusion

The proces of getting oxygen from the environment to the tissues of the body

37

Is composed of skeletal structures (bones) and soft tissues (muscles) that work together to allow proper respiratory mechanics to occue and help pump blood back to the heart during inspiration

Respiratory Pump

39

Mediastinum

The space in the chest between the lungs that contains all the internal organs of the chest except the lungs

40

Expiration

The process of actively or passively relaxing the inspiratory muscles to move air out of the body

42
