Respiratory Physiology 6

Question 1

Describe how a descent into water impacts barometric pressure and lung volume

Answer 1

Descent

= increase pressure, decrease volume

Question 2

Describe how an ascent from depths of water impacts barometric pressure and lung volume

Answer 2

Ascent

= decrease pressure, increase volume

Question 3

List the adaptions of deep diving animals

Answer 3

Question 4

Explain how gills functions as a gas exchange

Answer 4

Water flows through the gills and O2 is diffused through it

Question 5

Explain counter current flow

Answer 5

The water flows in the opposite direction of the blood flow

Question 6

Describe the avian respiratory system

Answer 6

No mixing of air 
Allows counter-current multiplication
avian air capillaries are interconnected
Pulmonary capillaries 
Thickness of the blood-gas barrier is 30% less than in mammalian alveoli

Question 7

List the adaptation of high flying birds

Answer 7

Experienced at high altitudes

= altitude hypoxia and increased PCO2 and acidosis

Question 8

Descrive the acute effects of hyperbaric hypoxia on pulmonary blood flow, diffusion, gas transportation and control of breathing (incomplete)

Question 9

Describe the pathophysiology of brisket disease (incomplete)
