Question:

A man's water intake is sufficient for his diet. However, his blood is always too concentrated as it passes through the hypothalamus. Suggest a possible reason for this observation.

Hypothalamus:

The hypothalamus is a vital part of the human brain that carries out multiple functions and is located just above the pituitary gland. Hypothalamus is majorly involved in maintain the homeostatic condition of the body and release hormones appropriately. The major hormones released are oxytocin and anti-diuretic hormone.

Answer and Explanation: 1

As the blood is responsible for carrying numerous essential components, hence human physiology depends on its fluidity. Sometimes, the blood gets more concentrated than normal; the hypothalamus can detect such a situation. Blood can get thicker due to:

  • Polycythemia vera (PV) is a medical condition in increased production of platelets and red and white blood cells, making the blood thick.
  • Elevated concentration of coagulating factors thickens the blood and might cause an increased risk of blood clotting.

The hypothalamus recognizes the thickness in blood and releases anti-diuretic hormone and increases kidney permeability and water re-absorption to dilute the blood.
