Question

Choose the wrong statement

A.
a) Solubility of CO2 in blood is 20-25 times higher than that of oxygen

B.
b)the total volume of air accommodated in the lung at the end of forced inspiration is called the vital capcity

C.
c)O2can bind with haemoglobin in a reversible manner to form oxyhaemoglobin

D.
d)every 100ml of deoxygenated blood delivers approximately 4ml of CO2 to the alveoli

Answer 1

Answer:

Option B

Explanation: volume of air a person can breath out after forced expiration called vital capacity

Answer 2

The wrong statement is option b)the total volume of air accommodated in the lung at the end of forced inspiration is called the vital capacity.

Vital capacity is the maximum volume of air a person can breathe in after a forced expiration or the maximum volume of air a person can breathe out after a forced inspiration.

It varies from 3400mL to 4800mL.

• The solubility of CO₂ in the blood is 20-25 times higher than that of oxygen.
• O₂ can reversibly bind with hemoglobin to form oxyhemoglobin.
• Every 100mL of deoxygenated blood delivers approximately 4mL of CO₂ to the alveoli.

Hence, the correct answer is option (b).
