Understanding the Functions of Red Blood Cells

Red blood cells (RBCs), also known as erythrocytes, have specific roles in the human body that are central to maintaining life and health. The primary function of red blood cells is to transport oxygen from the lungs to the tissues throughout the body.

The options provided include:

1. Transport oxygen
2. Aid in digestion
3. Produce antibodies
4. Transport oxygen to body tissues

Analyzing the Options

1. Transport oxygen: This is a correct statement but not fully descriptive.

2. Aid in digestion: This option is incorrect as RBCs do not play a role in the digestive process.

3. Produce antibodies: This is incorrect; antibodies are produced by a different type of white blood cell called lymphocytes.

4. Transport oxygen to body tissues: This option accurately describes the vital function of red blood cells, highlighting their role in delivering oxygen.

Conclusion

Both options (a) and (d) indicate the function of red blood cells regarding oxygen. However, option (d) provides a more complete understanding by specifying the connective action of transporting oxygen to body tissues.

Final Answer

The primary function of red blood cells in the body is to transport oxygen to body tissues (option d).
