Detailed explanation-1: -Also called erythrocyte and RBC. Blood cells. Blood contains many types of cells: white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets. Blood circulates through the body in the arteries and veins.

Detailed explanation-2: -Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells). Checking the number of white blood cells in the blood is usually part of a complete blood cell (CBC) test.

Detailed explanation-3: -Red cells, sometimes referred to as erythrocytes, pick up oxygen as blood passes through the lungs and release it to the cells in the body. White cells, sometimes referred to as leukocytes, help fight bacteria and viruses. Platelets help your blood clot in response to a cut or a wound.

Detailed explanation-4: -They begin their life as stem cells, and they mature into three main types of cells-RBCs, WBCs, and platelets. In turn, there are three types of WBC-lymphocytes, monocytes, and granulocytes-and three main types of granulocytes (neutrophils, eosinophils, and basophils). See them in action in “Meet the blood cells".

Detailed explanation-5: -The main difference between RBCs and WBCs is their function. RBCs carry oxygen throughout the body, while WBCs fight off infection. RBCs are also smaller and have a concave shape, while WBCs are larger and have different shapes. Finally, RBCs contain haemoglobin, while WBCs do not.
