1
Q

What is the cardiorespiratory system?

A

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

2
Q

What is the cardiovascular system?

A

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

3
Q

What is the heart?

A

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

4
Q

Where is the heart located?

A

The mediastinum.

5
Q

Sinoatrial (SA) Node is considered the:
&
Is one of the _____ heart beats.

A

Pace maker of the heart.
&
Two.

6
Q

Atrioventricular (AV) Node receives:

A

Heartbeat impulses from sinoatrial node & directs them to ventricles. Creates a stall in heart beat, delays signal to lower portion of heart.

7
Q

(A)trium:

A

Superior chamber of heart, receives veins and forces it into ventricles. 1st contraction.

8
Q

(V)entricle:

A

Inferior chamber of heart that receives blood from atrium & forces blood into arteries. 2nd contraction.

9
Q

**Stroke Volume

A

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

10
Q

Heart Rate (HR)

A

The rate at which the heart pumps.

11
Q

Cardiac Output (Q)

A

Heart rate X stroke volume = cardiac output. Is the volume of blood pumped by the heart per minute. The overall performance of the heart.

12
Q

Which is a product of multiplying the amount of BPM x the volume per beat of the heart?

A

Cardiac Output.

13
Q

Radial pulse is best taken with what strategy and when?

A

Light pressure on the thumb side when waking in am. Do 3 mornings to get average.

14
Q

Blood:

A

Fluid that circulates in the heart, arteries, capillaries, and veins. Transports nutrients & oxygen to all parts of the body and also rids the body of waste products. Transports hormones, carries heat through body, regulates acid balance, protects by clotting, contains immune cells.

15
Q

Blue blood=

A

Deoxygenated blood.

16
Q

Blood vessels:

A

Network of hollow tubes that circulates blood throughout body.

17
Q

Arteries:

A

Vessels that transport blood away from heart.

18
Q

**Capillaries:

A

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

19
Q

What are the 5 types of blood vessels?

A

Arteries, Capillaries, Veins, Arterioles (smaller arteries), Venules (smaller veins).

20
Q

In which order does blood travel through blood vessels?

A
  1. Arteries (red)
  2. Arterioles (red)
  3. Capillaries (red)
  4. Venules (blue)
  5. Veins (blue)
    HEART <3
21
Q

Veins:

A

Vessels that transport blood from the capillaries toward the heart.

22
Q

** Arterioles:

A

Small terminal branches of an artery, which end in capillaries.

23
Q

Medium sized arteries further divide into smaller _______ that are called _________ and eventually turn into microscopic vessels known as _________.

A
  1. Arteries
  2. Arterioles
  3. Capillaries
24
Q

Venules:

A

The very small veins that connect capillaries to the larger veins.

25
Q

Respiratory system:

A

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

26
Q

When stressed the body uses our _________ breathing muscles more.

A

Secondary.

27
Q

Our primary breathing muscles are:

A

Diaphragm, Sternum, Ribs, Vertebrae

28
Q

Our secondary breathing muscles are:

A

Scalenes, Sternocleidomastoid

29
Q

Diffusion:

A

The process of getting oxygen from the environment to the tissues of the body. From blue to red is where the diffusion occurs.

30
Q

Maximal oxygen consumption (Vo2 max)

A

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

31
Q

_________ shape can be measured in Vo2 max.

A

Cardio respiratory.

32
Q

Vo2 max equation is:

A

Vo2 = Q X a - Vo2 difference.

33
Q

Rockport walk test serves what purpose and how is it performed?

A

Best estimates Vo2 max. It’s performed by walking a mile as fast as possible
