Cardiorespiratory System

Question 1

What is the cardiorespiratory system?

Answer 1

Cardiovascular and respiratory systems: consists of the heart and blood vessels which work with the respiratory system. Tgese vody systems carry oxygen to the muscles and organs of the body, and remove waste products such as co2

Question 2

What is the cardiovascular system?

Answer 2

Heart, blood and blood vessels. Is an organ system that permits blood to circulate and transport nutrients such as amino acids and electrolytes, oxygen, carbon dioxide, hormones and blood cells to and from the cells in the body to provide nourishment

Question 3

what is a cardiac muscle?

Answer 3

Shorter, more tightly connected than skeletal muscles, involuntary, fires synchronously

Question 4

what is the Atria?

Answer 4

Smaller, Superior chamber of the heart, receive blood from veins. Each of the two upper cavities of the heart from which blood is passed to the ventricles

Question 5

What is the function of the right atrium?

Answer 5

Gathers deoxygenated blood returning to the heart.

Question 6

What is the function of the left atrium?

Answer 6

Gathers oxygenated blood from the lungs

Question 7

explain briefly how the cardiorespiratory system works?

Answer 7

The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which sends it to the lungs to be oxygenated. The left atrium acts as a holding chamber for blood returning from the lungs and to act as a pump to transport blood to other areas of the heart and the body through the aorta

Question 8

What is the Sinoatrial node?

Answer 8

located in the right atrium initiate impulses from the heart rate “the heart’s natural pacemaker”
In other words send out regular electrical impulses from the chamber (The Atrium) causing it to contract and pump blood into the bottom chamber (The ventricle)

Question 9

what are the ventricles?

Answer 9

Larger, inferior chambers of the heart, pump blood out

Question 10

What is the function of the right ventricle?

Answer 10

Pumps deoxygenated blood to the lungs

Question 11

What is the function of the left ventricle?

Answer 11

Pumps oxygenated blood to the body

Question 12

what are arteries?

Answer 12

Carry blood away from the heart. They are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body

Question 13

what are veins?

Answer 13

Transferred blood back to the heart

Question 14

What is arterioles?

Answer 14

Small branches of arteries, end in capillaries

Question 15

what are capillaries?

Answer 15

Smallest blood vessels, site of gas, chemical, and water Exchange. they are very tiny blood vessels, so small that a single red blood cell can barely fit through them.

Question 16

what are blood vessels?

Answer 16

Are the components of the circulatory system that transport blood through the human body. The vessels transport blood cells, nutrients, and oxygen to the tissues of the body.

Question 17

What are the three kinds of blood vessels?

Answer 17

Arteries, veins, and capillaries.

Question 18

What are venules?

Answer 18

Very small veins, connect capillaries to larger veins

Question 19

what is stroke volume?

Answer 19

Amount of blood pumped with each contraction

Question 20

What is the heart rate?

Answer 20

The rate at which the heart pumps, average on train adult 70 to 80

Question 21

what is cardiac output?

Answer 21

Volume of blood pumped through the circulatory system per minute, heart rate X stroke volume

Question 22

What is the respiratory system?

Answer 22

Lawrence and respiratory passageways , brings in oxygen, removes CO2

Question 23

what is inspiration?

Answer 23

Contracting inspiratory muscles to move air into lungs

Question 24

what are the inspiratory muscles

Answer 24

• Primary: diaphragm, external intercostals

- secondary: scalenes, pectoralis minor, sternocleidomastoid

Question 25

what is expiration?

Answer 25

relaxing inspiratory muscles( passive), Contracting expiratory muscles (active) to move air out

Question 26

What is maximal oxygen consumption ( VO2 max

Answer 26

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

Question 27

what is dysfunctional breathing?

Answer 27

Associated with the stress and anxiety, may result in headaches, fatigue, for circulation, and/or poor Sleep patterns

Question 28

cardiorespiratory exercise:

What are the benefits of increasing it?

Answer 28

Cardiac output, breathing efficiency coma 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 29

cardiorespiratory exercise:

what happens if you decrease it?

Answer 29

resting heart rate, cholesterol, blood pressure, and the risk of heart disease, blood clots, depression, anxiety, obesity, and diabetes
