What are the formed elements found in blood?

The correct answer identifies the formed elements of blood as red blood cells, white blood cells, and platelets. These components are crucial for the various functions that blood performs in the body.

Red blood cells, or erythrocytes, are responsible for transporting oxygen from the lungs to the tissues and carrying carbon dioxide back to the lungs for exhalation. They contain hemoglobin, which binds to oxygen and carbon dioxide.

White blood cells, or leukocytes, are part of the immune system. They help the body fight infections and foreign invaders. There are several types of white blood cells, each with specific roles in immune response.

Platelets, or thrombocytes, play a key role in hemostasis, which is the process that prevents and stops bleeding. They contribute to the blood clotting process by aggregating at injury sites and providing a surface for clotting factors to assemble.

Plasma, while an important component of whole blood, is not considered a formed element. Plasma is the liquid portion of blood that carries cells and other components, such as nutrients, hormones, and waste products.

The other options include either plasma or fibrin as formed elements, which misrepresents the classification since plasma is the liquid matrix and not a formed
