Abstract
Blood is a complex and vital fluid that sustains life by delivering oxygen, nutrients, and immune protection while removing waste products. The corpuscular elements of blood—red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes)—are essential for maintaining homeostasis. This article provides a detailed examination of the structure, function, and clinical significance of these elements, emphasizing their roles in oxygen transport, immune defense, and hemostasis. By understanding the intricacies of these components, we can better appreciate their contributions to health and disease.
