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.

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
