CBSE Class 11-science - Exchange and Transport of Gases Videos
Exchange of Gases at Alveoli
This video explains why diffusion of gases occurs only in the alveolar region and not in the other parts of the respiratory system.
- gas exchange in the lungs happen by the process of
- A: exchange of O2 and CO2 occurs by active transport R: rate of diffusion does not depend on the partial pressure of O2 and CO2
- State the primary site of exchange of gases in lungs.
- Apart from RBCs, which is the other component of blood which carries oxygen?
- Name the substance formed after the combination of oxygen and haemoglobin.
- How many molecules of oxygen can a single haemoglobin molecule carry?
- State the significance of the sigmoid oxygen dissociation curve.
- Under normal physiological conditions, state the amount of oxygen which will be delivered by 100 ml of blood.
- State the name of the form in which CO2 is transported by blood.
- With respect to the partial pressures of oxygen and carbon dioxide, when are more molecules of carbaminohaemoglobin formed?
