Question

Describe the factors or principles that contribute to oxygen unloading in the tissues, and loading in the lungs. What factor contribute to increased CO₂ binding to hemoglobin in the tissues, and unloading in the lungs? What are the partial pressures of O₂ and CO₂: 1) in the arterial blood coming from well-functioning lungs at sea level (after gas exchange), and 2) in venous blood leaving working tissues?

Answer 1

factors or principles that contribute to oxygen unloading in the tissues,

1) Increased PCO​​​​2

2) Decreased pH, Increased H+

3) Increased 2,3- BPG

4) Increased Temperature

Q - Arterial Blood coming out from lung has -

pO2 - 100, pCO2 - 40

Q - Venous blood leaving a worked tissue

pO2 - 40, pCO2 - 46
