Understand that blood is a specialized bodily fluid that performs various functions, including transportation of nutrients, oxygen, and waste products.
Identify the main components of blood: red blood cells, white blood cells, platelets, and plasma.
Red blood cells (erythrocytes) are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to be exhaled.
White blood cells (leukocytes) are part of the immune system and help the body fight infections and other diseases.
Platelets (thrombocytes) are cell fragments that play a crucial role in blood clotting, while plasma is the liquid component that carries cells, nutrients, hormones, and waste products.
