Hatshy [7]

Answer:

The correct answer is -

anemia- erythrocytes

easy bleeding- platelets

Repeated infections - leucocytes

enlarged lymph nodes- leucocytes

shortness of breath- erythrocytes

excessive bruising- Platelets

Explanation:

Cancer of the lymphocytes is chronic lymphocytic leukemia (CLL). Lymphocytes are a type of white blood cell involved in the body's immune system.

Platelets are tiny blood cell fragments that help your body form clots to stop bleeding. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.

Erythrocytes are red blood cells that travel in the blood. They carry oxygen from the lungs to the body and bring carbon dioxide back to the lungs to be expelled.

Leucocytes- White blood cells (also called leukocytes or leucocytes and abbreviated as WBCs) are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
