Respiratory System (Lab Exam #2) Flashcards

1
Q

what is the major function of respiration of respiratory system?

A

major function of respiration is to supply the body with oxygen for cellular respiration and dispose of carbon dioxide (waste product of cellular respiration)

Q

what are the 4 processes of respiration?
describe them

A

1.) pulmonary ventilation (breathing)
- movement of air into and out of lungs
2.) external respiration
- O2 and CO2 exchange between lungs and blood
3.) transport
- O2 and CO2 in blood
4.) internal respiration
- O2 and CO2 exchange between systemic blood vessels and tissues

Q

what is pleura?
how many layers? describe them

A
  • thin, double-layered membrane that surrounds the lungs and lines the inside of the chest cavity.

2 layers:
1.) outer layer = parietal pleura
- adheres to the thoracic wall

2.) inner layer = visceral pleura
- covers the lung tissue.

  • space between the two layers= pleural cavity
  • contains a small amount of lubricating serous fluid that helps the 2 layers slide smoothly against each other during breathing movements

Q

what is expiratory reserve volume (ERV)?

A
  • the extra amount of air that a person can breathe out after a normal breath
  • amount of air that can be forcefully exhaled after exhaling normally, and represents the maximum amount of air that can be exhaled from the lungs with extra effort

Q

what is inspiratory reserve volume (IRV)?

A
  • the extra amount of air that a person can breathe in after a normal breath
  • amount of air that can be forcefully inhaled after inhaling normally, and represents the maximum amount of air that can be inhaled into the lungs with extra effort

Q

what is vital capacity (VC)?

A
  • largest amount of air that a person can breathe in and out with the deepest possible breaths
  • maximum amount of air that a person can move in and out of their lungs
  • made up of 3 parts
    1.) amount of air that is normally breathed in and out (tidal volume)
    2.) plus the extra air that can be breathed in (inspiratory reserve volume
    3.) the extra air that can be breathed out (expiratory reserve volume)

VC = TV + IRV + ERV
