Question

Cardiac output of an individual is about 5000 ml. Under normal physiological conditions how much O2 will be delivered to tissues : 1) 100 ml 2) 5 ml 3) 250 ml 4) 750 ml

Answer 1

Answer:

According o NCERT

Step-by-step explanation:

Every 100ml carry 5 ml to tissue ie 5%

For 5000ml ,O2 will be delivered to tissues = 250ml

Answer 2

Answer:

Under normal physiological conditions, 750 ml $O_{2}$ will be delivered to the tissues.

Step-by-step explanation:

Transport of Oxygen

• Oxygen is transported in two ways:

           physically dissolved in the blood and

           chemically combined with the hemoglobin in the RBCs.

• More oxygen is normally transported combined with hemoglobin than is physically dissolved in the blood.
• 15 ml of oxygen is delivered by 100ml of oxygenated blood to the tissues under normal physiological conditions.

That is, 15 ml $O_{2}$ is delivered in 100 ml of oxygenated blood

              ∴ For 5000 ml, the amount of $O_{2}$ delivered = 5000 x $\frac{15}{100}$

                                                                                       = 750 ml

Hence, 750 ml is the required answer.
