Q

Heart’s Conduction System

A

Sends an electrical signal rapidly through all the cardiac cells

  • Transmitted through the SA node through both atria and down into the ventricles
  • Internodal pathways then transfer the impulse from the SA node to the AV node which then delays the impulse slightly
  • The AV bundle conducts the impulse to the ventricles for contraction via the light and right bundle branches of the purkinje fibers

Q

Blood Flow Through the Heart

A

Deoxygenated blood -> superior vena cava -> right atrium -> Tricuspid valve -> Right Ventricle -> Pulmonary valve -> left pulmonary artery -> lungs -> oxygenated blood -> pulmonary veins -> left atrium -> mitral valve -> left ventricle -> aortic valve -> Aortic Arch -> Descending aorta -> body

25
Q

2 Atrioventricular Valves

A

Tricuspid valve, Mitral Valve

26
Q

2 Semilunar Valves

A

Pulmonary and Aortic valves

27
Q

Tricuspid Valve

A

Controls BF from the right atrium to the right ventricle

28
Q

Mitral Valve

A

Controls BF from left atrium to the left ventricle

29
Q

Aortic Valve

A

Controls BF from the left ventricle to the aorta going to the entire body

30
Q

Pulmonary Valve

A

Controls blood flow from the right ventricle to the pulmonary arteries going to the lungs

31
Q

Stroke Volume (SV)

A

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

32
Q

SV Formula

A

EDV - ESV

33
Q

EDV

A

End-diastolic volume

-The filled volume of the ventricle before contraction

34
Q

ESV

A

End-systolic volume

-The residual volume of blood remaining in the ventricle after ejection

35
Q

Heart Rate (HR)

A

The rate at which the heart pumps

36
Q

Cardiac Output (Q)

A

The volume of blood pumped by the heart per minute, the overall performance of the heart
-HR X SV

37
Q

3 Kinds of Cells in Blood

A
  • RBC (carry oxygen)
  • WBC (help fight infection)
  • Platelets (clotting)
38
Q

Blood and Transportation

A
  • Transports O2 to all bodily tissues and removes waste products
  • Transports hormones and nutrients
  • Helps remove heat from internal to external regions of the body
39
Q

Blood and Regulation

A
  • Blood helps regulate body temp
  • Regulation of pH levels in the body
  • Regulation of water content of body’s cells
40
Q

Blood and Protection

A
  • Clotting mechanism provides from excessive blood loss

- Provides specialized immune cells to reduce risk of disease and illness

41
Q

3 Major Types of Blood Vessels

A

Arteries, capillaries, veins

42
Q

Arteries

A

Carry blood away from the heart

-Aorta largest artery branches into medium sized arteries to arterioles and end in capillaries

43
Q

Capillaries

A

The site of exchange of chemicals and water between the blood and tissues

44
Q

Veins

A

Carry blood back to the heart

-Venules are vessels that collect blood from the capillaries and progressively merge together to form veins

45
Q

Respiratory System Function

A

Bring O2 in the lungs and remove CO2 from the lungs and ensure proper cellular function

46
Q

Respiratory System Structure

A

Includes: airwars, lungs, and respiratory muscles

47
Q

Respiratory Pump

A

Bones and muscles that work together to allow proper respiratory mechanics to occur and help pump blood back to the heart during inspiration

48
Q

2 Phases of Breathing

A
  • Inspiration

- Expiration

49
Q

Inspiration

A

Inhalation

50
Q

Inspiration Muscles

A

Diaphragm, external intercostals, scalenes, sternocleidomastoid, pec minor

51
Q

Expiration

A

Exhalation

52
Q

Expiration Muscles

A

Internal Intercostals, Abdominals

53
Q

2 Categories of Respiratory Passages

A

Conducting Airways, and respiratory airways

54
Q

Conducting Airways (8)

A

Consists of all structures that air travels through before entering the respiratory airways
-Nasal and oral cavities, mouth, pharynx, larynx, trachea, pulmonary bronchi, bronchioles

55
Q

Respiratory Airways

A

Collect the channeled air coming from conducting airways

-Alveoli and alveolar sacs

56
Q

Diffusion

A

The process of getting O2 from the environment to the tissues of the body through the blood stream
-Takes place in alveolar sacs to get O2 into blood

57
Q

Cardiorespiratory System Function

A

Provide the human movement system with many essential elements while removing waste products

58
Q

Oxygen Consumption/Uptake

A

The use of O2 by the body

59
Q

Resting and Maximal Oxygen Consumption (VO2)

A
