RP overview

Question 1

Aerobic respiration formula

Answer 1

C6H12O6 + 6O2 -> 6CO2 + 6H2O

Question 2

Formation of carbonic acid formula

Answer 2

C6H12O6 + 6O2 -> 6CO2 + 6H2O -> 6H2CO3

Question 3

Dissociation of carbonic acid into acid and basic components

Answer 3

H2CO3 -> H+ + H2CO3^-

Question 4

What is the name of the acid and basic components of the dissociation of carbonic acid?

Answer 4

Acidic - H+
Basic - Bicarbonate ion

Question 5

What is the whole reaction from the products of aerobic respiration to dissociation of carbonic acid?

Answer 5

CO2 + H2O -> H2CO3 -> H+ + HCO3 -

Question 6

Ventilation formula

Answer 6

Minute ventilation (l/min) = tidal volume (l) x respiratory rate (bpm)

Question 7

What is hyperventilation

Answer 7

removal of too much CO2 from the body (excessive ventilation) - alkalosis

Question 8

What is hypoventilation?

Answer 8

removal of too little CO2 from the body (not enough ventilation) - acidosis

Question 9

Consequences of hypoventilation?

Answer 9

• acidaemia (pH will decrease)
• acidosis causes a build up of carbonic acid

Question 10

Anaerobic respiration

Answer 10

• doesn’t need O2
• produces lactate due to hypoxaemia (lack of oxygen)

Question 11

Functions of respiratory system

Answer 11

• speech
• swallowing: upper part of respiratory tract (epiglottis) forms junction with GI tract
• biochemical function: metabolism of blood borne substances
  -clotting

Question 12

Control of clotting

Answer 12

heparin - inhibits coagulation
thromboplastin - promotes coagulation

Question 13

summary of respiratory system function

Answer 13

speech
swallowing
clotting
biochem functions
blood reservoir for CV system

Question 14

What term refers to gas exchange between atmosphere and blood?

Answer 14

external respiration
