________ are the Blood Cells That Help Provide a Defense

Question

________ are the blood cells that help provide a defense against disease organisms.
A)Leukocytes
B)Platelets
C)Erythrocytes
D)Both leukocytes and erythrocytes

Accepted Answer

Leukocytes, also known as white blood cells, are the blood cells that defend the body against disease organisms. They do this by identifying and attacking foreign invaders such as bacteria and viruses. Platelets, on the other hand, are responsible for blood clotting, and erythrocytes are red blood cells that carry oxygen throughout the body. While erythrocytes do play a critical role in the body's overall health, they are not directly involved in fighting off pathogens. Therefore, the best choice is A) Leukocytes.
