List the components of blood as: red blood cells, white blood cells, platelets and plasma

The components of blood are essential for various physiological functions in the body. Here’s a list of the main components:

1. Red Blood Cells (RBCs):
   • Also known as erythrocytes, these cells are primarily responsible for transporting oxygen from the lungs to the body’s tissues and returning carbon dioxide from the tissues back to the lungs. They contain hemoglobin, a protein that binds oxygen.
2. White Blood Cells (WBCs):
   • Also known as leukocytes, these cells are part of the immune system and help defend the body against infections and diseases. There are several types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specific roles in immune response.
3. Platelets:
   • Also called thrombocytes, platelets are cell fragments that play a crucial role in blood clotting. They aggregate at sites of injury to form clots and prevent excessive bleeding.
4. Plasma:
   • Plasma is the liquid component of blood, making up about 55% of its volume. It consists mainly of water (about 90%) and contains proteins (such as albumin and clotting factors), electrolytes, nutrients, hormones, and waste products. Plasma serves as a transport medium for blood cells and various substances throughout the body.
