Question 7

Cattle lungs why are they less efficient . Why

Answer 7

Small lungs relative to body size 
Non functional space 
Bronchioles and alveoli relatively small
Less ventilation with each breath 
Once collapsed stays collapsed 
Consolidation if advanced not reversible 
Susceptible to hypoxia

Question 8

Infalammtion in the lungs

Answer 8

Swelling and oedema 
Increased secretions -thick or thin 
Decreased perfusion of blood 
Decreased gaseous exchange 
Hypoxia 
Increased blood co2
Respiratory acidosis

Hypoxia

Answer 9

Brain increased permeability of blood brain barrier
Respiratory centre less functional
Vasomotor less functional
All vital control centers inhibited
