Q

Left atrium

A

gathers oxygenated blood from lungs

17
Q

Ventricle

A

inferior chamber of the heart that receives blood from its corresponding atrium and forces blood into arteries. larger than the atrium

18
Q

Right ventricle

A

has thin walls and pumps under low pressure

19
Q

Left ventricle

A

has thicker walls and pumps under high pressure because it pumps blood out to the rest of the body

20
Q

Respiratory system

A

lungs and respiratory passageways that collect oxygen from the external environment and transport it to the blood stream

21
Q

Inspiration

A

inhalation. actively contracting the inspiratory muscles to move air into the body

22
Q

Expiration

A

exhalation. process of actively or passively releasing inspiratory muscles to move air out of the body

23
Q

Respiratory pump

A

the thoracic and abdominal structures that help with the contraction and expansion of the lungs

24
Q

Muscles for inhalation

A

scalene muscles, the pectoralis minor, sternocleidomastoid, and the diaphragm

25
Q

Muscles of exhalation

A

internal intercostals, abdominal muscles

26
Q

Resting oxygen consumption (VO2)

A

approx 3.5 mL of oxygen per kg of bodyweight per minute. 1 MET

27
Q

Maximal oxygen consumption (VO2max)

A

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