PHYSIO

Hb Modifications

Mech of Path (3 steps) + Types (2)?

Answer 0

↓O2 bound to Hb = ↓O2 Sat = ↓O2 Content of blood.

• Methemoglobinemia
• CO Poisoning (Carboxyhemoglobinemia)

Question 1

PHYSIO

Lung Products (5)?

Answer 1

• Surfactant
• ACE (INACTIVATION of Bradykinin)
• Histamine (bronchoconstriction)
• Kallikrein (ACTIVATION of Bradykinin)
• Prostaglandins

Question 3

ANAT

R Main Bronchus

Anatomical Feature + Clinical Application?

Answer 3

Shorter, wider + more vertical.

Easier for foreign bodies to get lodged in it.

Question 3

PHYSIO

Responses to Exercise (9: 4 RESP + 2 ABG + 3 Metab)?

Answer 3

• ↑CO ->↑Pulm bl flow
• ↑Ventilation rate ->↑O2 consumption + CO2 production
• ↓Dead Space
• V/Q ratio more evenly distributed in lung
• Arterial pH:
  
  • Moderate exercise: NO change
  • Strenuous exercise:↓ (lactic acidosis)
• PvO2↓+ PvCO2↑
  (excess CO2 produced by exercising muscle carried to lungs in venous blood)
• ATP Production:
  - INITIALLY = regenerated from Creatine Phosphate
  - LATER = obtained by oxidation of muscle Glycogen
• Glucose + F.A taken up and oxidized by muscle
• Glycogenolysis + Gluconeogenesis as bl glucose↓(Liver)

Question 4

PHYSIO

Responses to Exercise (9: 4 RESP + 2 ABG + 3 Metab)?

Answer 4

• ↑CO ->↑Pulm bl flow
• ↑Ventilation rate ->↑O2 consumption + CO2 production
• ↓Dead Space
• V/Q ratio more evenly distributed in lung
• Arterial pH:
  
  • Moderate exercise: NO change
  • Strenuous exercise:↓ (lactic acidosis)
• PvO2↓+ PvCO2↑
  (excess CO2 produced by exercising muscle carried to lungs in venous blood)
• ATP Production:
  - INITIALLY = regenerated from Creatine Phosphate
  - LATER = obtained by oxidation of muscle Glycogen
• Oxidation of muscle Glucose + F.A
• Liver: Glycogenolysis + Gluconeogenesis as bl glucose↓
