Types of Blood Cells

The human body consists of three types of blood cells, namely:

Red blood cells (RBC) / Erythrocytes
Red blood cells are primarily involved in carrying oxygen, nutrients, and other materials throughout the body. These blood cells also eliminate waste from the body.

White Blood Cells (WBC)/ leukocytes
White blood cells are specialized cells that serve as a body’s defense system. They provide immunity by preventing dangerous bacteria and harmful microorganisms.

Platelets / Thrombocytes
Cells called platelets aid in the formation of clots and stop bleeding. They take action at the wound or damaged site.

The circulatory system is a network of organs that permit the circulation of blood. The circulatory system’s other name is the Cardiovascular system or the vascular system. The primary function of the circulatory system is to transport blood to each part of the body. It is necessary because it carries nutrients, oxygen, carbon dioxide, hormones, and blood cells that are necessary for the hydration and growth of each organ’s cell population.

The Blood circulatory systems are many of the most important processes of the body because they deliver required amounts of oxygen in every portion of the body. The arteries transport the oxygenated blood from the heart to the body parts. Oxygen is provided to the body through diffusion and the blood becomes deoxygenated. This deoxygenated blood is carried return to the heart for oxygenation. This process known as blood circulation occurs continuously in all vertebrates.
 

Biology is part of many competitive exams SSC CGL, UPSC, SSC CPO, and Railways. We have written depth notes on the circulatory System To help you understand the Human Circulatory System in a much better way. To know more about Circulatory System which is mentioned below.
