Answer: However, during exercise, many other muscles become important to respiration. During inspiration, the external intercostals raise the lower ribs up and out, increasing the lateral and anteroposterior dimensions of the thorax.
Answer: The correct option is IRON DEFICIENCY ANAEMIA
Explanation:
Anaemia is a condition that arises when there is not enough haemoglobin available to carry sufficient oxygen from the lungs to supply the needs of the tissues. It occurs when the rate of production of mature cells entering the blood from the reb bone marrow does not keep pace with the rate of haemolysis.. Anaemia can be classified based on:
--> impaired erythrocyte production example, Iron deficiency anaemia. Or
--> increased erythrocyte loss example, haemolytic anaemia.
IRON DEFICIENCY ANAEMIA occurs when the amount of iron nutrient needed in the body system for the production of haemoglobin is decreased. The symptoms includes
- impaired work performance,
- general fatigue,
-pale skin,
- depressed immune function,
- impaired cognitive and nerve function, and impaired memory.
