The correct answer is C. Thrombocytes.
Platelets are also known as thrombocytes. They are small, irregularly shaped cell fragments that are essential for blood clotting. Platelets are produced in the bone marrow and circulate in the blood. When a blood vessel is damaged, platelets adhere to the damaged area and form a plug that stops the bleeding. Platelets also release chemicals that attract other platelets and help to form a clot.
A. Leucocytes, also known as white blood cells, are cells of the immune system that help the body fight infection.
B. Erythrocytes, also known as red blood cells, are cells that carry oxygen from the lungs to the tissues of the body.
D. Phagocytosis is a process by which cells engulf and destroy other cells or particles.
