GENERAL HISTOLOGY

Detailed explanation-1: -Blood contains → red blood cells, white blood cells, platelets and plasma which constitutes water, proteins, hormones, O2, CO2, glucose, salt, enzymes. Tissue fluid contains → O2, CO2, sugars, salts, amino acids, hormones, coezymes & white blood cells. Lymph contains → CO2, proteins, glucose and white blood cells.

Detailed explanation-2: -White blood cells are made in the bone marrow and are found in the blood and lymphatic tissue. They play an important role in immune response (the immune system’s reaction to the presence of foreign substances in the body).

Detailed explanation-3: -Lymph is a fluid that circulates throughout the body in the lymphatic system. It forms when tissue fluids/blood plasma (mostly water, with proteins and other dissolved substances) drain into the lymphatic system. It contains a high number of lymphocytes (white cells that fight infection).

Detailed explanation-4: -It helps bring oxygen and nutrients to cells and to remove waste products from them. As new tissue fluid is made, it replaces older fluid, which drains towards lymph vessels. When it enters the lymph vessels, it is called lymph. Also called interstitial fluid.
