Iron-Deficiency Anemia

Iron-Deficiency Anemia

Question 1. List two features of RBC in iron deficiency anaemia.
Answer:

RBC features in Iron deficiency anaemia

• Microcytic, hypochromic
• Count decreases or normal
• Life span is normal
• Peripheral smear shows anisocytosis and poikilocytosis

Question 2. Give examples of positive and negative feedback mechanism.
Answer:

Positive feedback mechanism:

• It is one in which the system reacts in such a way as to increase the intensity of change in same direction
• Example: Blood clotting mechanism, milk ejection reflex

Negative feedback mechanism:

• It is one in which the system reacts in such a way as to stop the change or reverse the direction of change
• Example: TSH released from pituitary gland stimulates thyroid gland to release thyroxin
• When thyroxin level increases, it inhibits the secretion of TSH from pituitary gland

Question 4. Functions of blood
Answer:

1. Nutritive
   • Blood carries the food absorbed from the digestive system to tissues for growth and production of energy
2. Respiratory
   • Blood transport oxygen from lungs to the tissues and carbon dioxide from the tissues to the lungs
3. Excretory
   • Waste products are carried through blood to excretory organs like kidney, skin and intestine
4. Transport of hormones and enzymes
   • Blood transports the hormones secreted from the endocrine glands to their target organs/ tissues
   • Blood also transports enzymes
5. Regulation of water balance
   • Water balance is regulated as the water content of the blood gets interchangable with interstitial fluid
6. Regulation of acid base balance
   • Blood maintains pH through the buffering system of plasma proteins and haemoglobin
   • This mechanism is called homeostasis

“Factors influencing success with iron-deficiency anemia studies: Q&A”

1. Regulation of body temperature
   1. Blood regulates body temperature due to its high specific heat
   2. It regulates through thermoregulatory mechanism due to which balance occurs between heat loss and heat gain in the body
2. Storage function
   • Blood stores substances like proteins, glucose, sodium and potassium so that these substances can be used during starvation, fluid loss, etc
3. Defensive function
   • White blood cells help in the defence of the body
