Blood is a vital fluid in the human body that performs essential functions necessary for sustaining life. Comprising about 7-8% of a person’s body weight, blood circulates through the vascular system, delivering oxygen and nutrients to cells and removing waste products like carbon dioxide. It consists of four main components: red blood cells, white blood cells, platelets, and plasma.

Red blood cells (RBCs), or erythrocytes, make up about 45% of blood volume. They contain hemoglobin, a protein that binds to oxygen in the lungs and transports it to tissues throughout the body. Hemoglobin also carries carbon dioxide from the tissues back to the lungs for exhalation.

White blood cells (WBCs), or leukocytes, are crucial for the immune system. They protect the body against infections and foreign invaders. There are several types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specific roles in immune defense.

Platelets, or thrombocytes, are small cell fragments essential for blood clotting. When a blood vessel is injured, platelets aggregate at the site and form a plug, releasing chemicals that help in clot formation to prevent excessive bleeding.

Plasma is the liquid component of blood, making up about 55% of its volume. It is a pale yellow fluid composed mostly of water, but also contains proteins, electrolytes, hormones, and waste products. Plasma serves as a medium for transporting nutrients, hormones, and waste products throughout the body.

Blood plays a crucial role in homeostasis, regulating body temperature, pH balance, and fluid volume. It also serves as a medium for hormone transport and immune responses.
