geniusboy [140]

Answer:

The correct answer is : oxygen

Explanation:

  • Oxygen is carried in the blood by two means:
  1. About 2% of the oxygen is carried in the dissolved form in blood plasma and in the water present in the red blood cells (RBCs).
  2. Rest 98% of the oxygen is carried in bound form with the haemoglobin as oxy-haemoglobin inside the RBCs.
  • RBCs lack nucleus. This place is occupied by hemoglobin molecules that  binds to oxygen and form oxy-hemoglobin.
  • This increases the capacity of each RBC so that it can carry more oxygen to all the parts in the body.

Vera_Pavlovna [14]
