Blood Cells
Blood Cells
Blood cells, also known as hemocytes, are cells produced by hematopoiesis and found mainly in the blood. Pronounced as /ˈblʌd sɛlz/, the term is derived from the Greek words 'haima' meaning 'blood' and 'kytos' meaning 'cell'.
Types of Blood Cells
There are three main types of blood cells:
- Red Blood Cells (RBCs), also known as erythrocytes, are responsible for carrying oxygen throughout the body. They contain a protein called hemoglobin that binds to oxygen.
- White Blood Cells (WBCs), or leukocytes, are part of the immune system and help the body fight off infections.
- Platelets, or thrombocytes, are cell fragments that play a crucial role in blood clotting.
Production of Blood Cells
Blood cells are produced in the Bone Marrow, a spongy tissue found in the center of certain bones. This process is known as Hematopoiesis. Hematopoietic stem cells (HSCs) in the bone marrow give rise to all types of blood cells.
Disorders Related to Blood Cells
There are several disorders related to blood cells, including:
- Anemia: A condition characterized by a lack of healthy red blood cells or hemoglobin.
