Intro to Respiratory System

Question 1

What 2 stages does respiration consist of?

Answer 1

• external (breathing)
• internal (cellular)
  
  • aerobic
  • anaerobic

Question 2

What is the respiration equation?

Answer 2

C₆H₁₂O₆ + 6O₂ to 6CO₂ + 6H₂O

Question 3

What systems is used in respiratory and cardiovascular systems?

Answer 3

• convective bulk flow systems for long distance transport
• diffusion for short distance movements

Question 4

Define metabolic rate.

Answer 4

rate of O₂ consumption

Question 5

What are normal values for VO₂ and VCO₂?

Answer 5

VO₂ 250ml/min

VCO₂ 200ml/min

Question 6

How do you calculate the respiratory quotient?

Answer 6

VCO₂/VO₂

Question 7

What is the consequence of blood O₂ falling?

Answer 7

tissues become hypoxic

Question 8

What is the consequence of blood CO₂ rising?

Answer 8

pH disturbances

Question 9

How does ventilation change in proportion to metabolic demand?

Answer 9

direct proportion

Question 10

What are the non-respiratory functions of the respiratory system?

Answer 10

• traps and dissovles blood clots
• defends against microbes
• heat and water loss due to ventilation
• reservoir of blood
• phonation (production of sound)
• metabolic functions
