Verified step by step guidance1
Understand the role of each formed element in the blood: White blood cells, Red blood cells, Platelets, and Plasma.
White blood cells (leukocytes) are primarily involved in the immune response, defending the body against infection.
Red blood cells (erythrocytes) are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to the lungs for exhalation.
Plasma is the liquid component of blood that carries cells and proteins throughout the body, but it is not a formed element.
Platelets, also known as thrombocytes, are cell fragments that play a crucial role in blood clotting by aggregating at the site of a blood vessel injury to form a plug and release chemicals that help in the clotting process.
