Blood Cells

Blood cells are the cellular components of blood, primarily consisting of three types: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

• Red blood cells carry oxygen from the lungs to the body and transport carbon dioxide back to the lungs for exhalation.
• White blood cells are key players in the immune system, defending the body against infections and foreign invaders.
• Platelets are crucial for blood clotting, helping to prevent excessive bleeding when injuries occur.

Together, these cells play vital roles in maintaining overall health and homeostasis.
