Red blood cells (RBCs) are responsible for carrying oxygen from the lungs to the body's tissues and carbon dioxide from the tissues to the lungs to be exhaled. They contain a protein called hemoglobin that binds to oxygen and carbon dioxide. White blood cells (WBCs), or leukocytes, are part of the immune system and help to protect the body from infection and disease. They detect and attack foreign substances, such as bacteria or viruses, in the body. They also produce antibodies and can differentiate between self and non-self cells in the body.
Red blood cells (RBCs) and white blood cells (WBCs) have distinct functions in the human body:
1. Red Blood Cells (RBCs):
- Oxygen Transport: The primary function of RBCs is to transport oxygen from the lungs to various tissues and organs throughout the body. They accomplish this through a protein called hemoglobin, which binds to oxygen in the lungs and releases it in the tissues.
- Carbon Dioxide Removal: RBCs also aid in the removal of carbon dioxide, a waste product produced by cells, from the tissues. Carbon dioxide binds to hemoglobin and is transported back to the lungs, where it is expelled from the body during exhalation.
- Oxygen-Carrying Capacity: RBCs have a unique biconcave shape and lack a nucleus, which allows them to be flexible and stack together, maximizing their surface area and enhancing their oxygen-carrying capacity.
2. White Blood Cells (WBCs):
- Immune Defense: WBCs play a crucial role in the body's immune defense system. They help protect the body against infections, diseases, and foreign invaders such as bacteria, viruses, and parasites.
- Pathogen Detection and Destruction: WBCs identify and target pathogens through various mechanisms, including phagocytosis (engulfing and destroying pathogens), producing antibodies, and coordinating immune responses.
- Inflammatory Response: WBCs, particularly a subtype called neutrophils, are involved in the inflammatory response, which helps control and eliminate infection or tissue damage.
WBCs are further classified into different types, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each subtype has specific functions and contributes to different aspects of the immune response.
Both RBCs and WBCs are essential for maintaining overall health and proper functioning of the human body. While RBCs primarily focus on oxygen transport and carbon dioxide removal, WBCs act as key players in the immune system, defending against infections and diseases.

RED BLOOD CELLS (RBCs): THE PRIMARY FUNCTION OF RED BLOOD CELLS ALSO KNOWN AS ERYTHROCYTES IS TO TRANSPORT OXYGEN FROM THE LUNGS TO THE BODY'S TISSUES AND CARRY CARBON DI OXIDE BACK TO LUNGS FOR ELIMINATION.
WHITE BLOOD CELLS:
WHITE BLOOD CELLS ALSO CALLED LEUKOCYTES PLAY A VITAL ROLE IN THE IMMUNE SYSTEM'S DEFENCE AGAINST INFECTIONS, DISEASES AND FOREIGN SUBSTANCES.

The function of a red and white blood cell in the human body is by fighting viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness. White blood cells are made in the bone marrow.
White blood cells (WBCs) and red blood cells (RBCs) have distinct functions in the human body:
**Red Blood Cells (RBCs):**
1. **Oxygen Transport**: RBCs contain hemoglobin, a protein that binds to oxygen in the lungs and transports it throughout the body, delivering oxygen to tissues and organs.
2. **Carbon Dioxide Removal**: RBCs also help in the removal of carbon dioxide, a waste product of metabolism. They transport carbon dioxide from tissues back to the lungs, where it can be exhaled.
**White Blood Cells (WBCs):**
1. **Immune Defense**: White blood cells play a crucial role in the body's immune system. They help defend against infections, bacteria, viruses, and other foreign invaders. Different types of WBCs have various functions in this defense, including phagocytosis (engulfing and destroying pathogens) and the production of antibodies to fight infections.
2. **Inflammation Response**: WBCs are involved in the inflammatory response, which is a protective mechanism the body uses to heal and defend against injuries and infections. They migrate to the site of infection or injury and release chemicals to help combat invaders.
3. **Immune Memory**: Some white blood cells, such as memory T-cells, are responsible for the immune system's ability to remember previous infections. This helps the body mount a faster and more effective response if it encounters the same pathogen again.
4. **Blood Cell Regulation**: Certain white blood cells, like lymphocytes, also play a role in regulating the overall number of blood cells in the body, including RBCs and other WBCs.
Both RBCs and WBCs are critical components of the circulatory system, working together to maintain the body's overall health and response to disease and injury.
