Answer 2

Answer:

The blood cells are red because of the interaction between iron and oxygen.

Blood has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.

White Blood Corpuscles or WBCs are called the 'soldiers of the body'. This is because of the property of the WBC that enables them to provide immunity to the body. Also known as leucocytes, WBCs protect our bodies from attack by harmful micro organisms and various diseases.
