Endocrine And Cardiorespiratory System

Question 1

Growth Hormone

Answer 1

Anabolic hormone; responsible for bodily growth up until puberty

Question 2

Inspiratory muscles

Answer 2

Primary - diaphragm, external intercostals

Secondary - scalenes, pectoralis minor, sternocleidomastoid

Question 4

Dysfunctional breathing

Answer 4

Associated with stress and anxiety; may result in headaches, fatigue, poor circulation, and/or poor sleep patterns

Question 5

Atria

Answer 5

Smaller, superior chambers of the heart; receive blood from veins

Question 7

Resting oxygen consumption (VO2)

Answer 7

3.5 ml x kg x min=1 metabolic equivalent (MET)

Question 8

Left atrium

Answer 8

Gathers oxygenated blood from the lungs

Question 11

Arteries

Answer 11

Carry blood away from heart

Question 12

Cardiorespiratory exercise increases

Answer 12

Cardiac output, breathing efficiency, oxygen transport and use, use of fats for fuel, mental alertness, ability to relax and sleep, tolerance to stress, lean body mass, metabolic rate

Question 13

Expiratory muscles

Answer 13

Internal intercostals, abdominals

Question 14

Inspiration

Answer 14

Contracting inspiratory muscles to move air into lungs

Question 16

Cardiac muscle

Answer 16

Shorter, more tightly connected than skeletal muscle; involuntary; fires synchronously

Question 17

Maximal oxygen consumption (VO2 Max)

Answer 17

Highest rate of oxygen transport and utilization achieved at maximal physical exertion

Question 19

Right ventricle

Answer 19

Pumps deoxygenated blood to lungs

Question 20

Arterioles

Answer 20

Small branches of arteries; end in capillaries

Question 24

Venules

Answer 24

Very small veins; connect capillaries to larger veins

Question 25

Stroke volume

Answer 25

Amount of blood pumped with each contraction

Question 26

Sinoatrial (SA) node

Answer 26

Located in the right atrium; initiates impulse for heart rate; “pacemaker for the heart”

Question 29

Veins

Answer 29

Transport blood back to heart

Question 30

Cardiorespiratory exercise decreases

Answer 30

Resting heart rate, cholesterol, blood pressure, and the risks of heart disease, blood clots, depression, anxiety, obesity, and diabetes

Question 32

Expiration

Answer 32

Relaxing inspiratory muscles (passive), contracting expiratory muscles (active) to move air out

Question 34

Cardiac output

Answer 34

Volume of blood pumped per minute; heart rate x stroke volume

Question 36

Capillaries

Answer 36

Smallest blood vessels; site of gas, chemical, and water exchange

Question 37

Ventricles

Answer 37

Larger, inferior chambers of the heart; pump blood out

Question 38

Left ventricle

Answer 38

Pumps oxygenated blood to the body

Question 39

Heart rate

Answer 39

The rate at which the heart pumps; average untrained adult = 70-80 bpm

Question 40

Respiratory system

Answer 40

Lungs and respiratory passageways; brings in oxygen, removes CO2

Question 41

Cardiovascular system

Answer 41

Heart, blood, and blood vessels

Question 46

Right atrium

Answer 46

Gathers deoxygenated blood returning to the heart

Question 49

Estrogen

Answer 49

Influences fat deposition on hips, buttocks, and thighs; responsible for female sex traits

Question 55

Insulin

Answer 55

Regulates energy and glucose metabolism in the body

Question 57

Testosterone

Answer 57

Anabolic hormone; responsible for male sex traits

Question 60

Cardiorespiratory system

Answer 60

Cardiovascular and respiratory systems

Question 64

Endocrine system

Answer 64

System of glands; secretes hormones to regulate bodily function
