Question

The ______ blood cells make antibodies whereas ______ blood cells help in respiration.

Answer 1

The white blood cells make antibodies whereas red blood cells help in respiration.

Explanation:

• White Blood Cells (Lymphocytes): A specific type of white blood cell called B-lymphocytes produces antibodies. These specialised proteins identify, bind to, and neutralise harmful pathogens such as bacteria and viruses, protecting the body from infections.
• Red Blood Cells (Erythrocytes): These cells contain a red, iron-rich protein called haemoglobin. Haemoglobin binds oxygen in the lungs and transports it to body tissues for cellular respiration, while also carrying carbon dioxide back to the lungs for exhalation.
