MICROANATOMY

Detailed explanation-1: -The bone marrow produces all the different types of white blood cells, including neutrophils, eosinophils, basophils, monocytes, B cells, and the cells that develop into T cells (T cell precursors). In the thymus, T cells multiply and are trained to recognize foreign antigens and to ignore the body’s own antigens.

Detailed explanation-2: -All cells of the immune system are created in the bone marrow from a common type of starting cell, called a stem cell. These stem cells later develop into specific cell types, including red blood cells, platelets (important for blood clotting), and white blood cells (important for immune responses).

Detailed explanation-3: -The lymphatic system is made up of: lymph nodes (also called lymph glands) – which trap microbes. lymph vessels – tubes that carry lymph, the colourless fluid that bathes your body’s tissues and contains infection-fighting white blood cells. white blood cells (lymphocytes).

Detailed explanation-4: -Hematopoiesis is blood cell production. Your body continually makes new blood cells to replace old ones. Hematopoiesis ensures you have a healthy supply of blood cells to supply oxygen to your tissue (red blood cells), fight infection (white blood cells) and clot your blood when you’re injured (platelets).

Detailed explanation-5: -Both B and T lymphocytes originate in the bone marrow but only B lymphocytes mature there; T lymphocytes migrate to the thymus to undergo their maturation.
