Differences Between Red And White Blood Cells

Last Updated on March 19, 2022 by QCity Editorial Stuff

Red blood cells can be found in humans, animals, and plants. White blood cells are also found in humans but their function is different from red blood cells.

Red blood cells are the most abundant type of cell in the human body. They perform many functions, including carrying oxygen to organs, fighting infections, and helping the heart pump blood. White blood cells are immune cells that kill bacteria and other foreign objects.

Red blood cells are the more abundant type of blood cell. They carry oxygen to all parts of the body, release carbon dioxide, and are involved in the bone marrow’s production of new red blood cells.

White blood cells are less abundant than red blood cells, but they perform a variety of functions that are critical to fighting infection. White blood cells help fight off bacteria and viruses by secreting substances called antibodies. Antibodies have many different subtypes which determine their functions.

Red blood cells are mostly responsible for transporting oxygen through the bloodstream. White blood cells are responsible for defending against infection.

White blood cells are larger than red blood cells and they mainly serve to fight infection. Red blood cells, on the other hand, transports oxygen to the body’s tissues and carry carbon dioxide back out of the body.

Comparison Table Between Red Blood Cells And White Blood Cells 

Parameter of comparisonRed blood cellsWhite blood cells 
Carry Red blood cells carry oxygen to the bodywhite blood cells help fight infections and diseases.
Responsible Red blood cells carry oxygen, which is what they do best. The red color is also an indicator that the cell contains hemoglobin, which makes it easier for them to transport oxygen throughout your bloodstreamOn the other hand, white blood cells are mainly responsible for fighting infections and diseases by killing virus-infected cells or releasing proteins called cytokines that
Size Red blood cells are typically half the size of white blood cells, which makes them twice as dense. White blood cells can detect and respond to a vast array of pathogens without detection, while red blood cells only react to a certain number of viruses and bacteria.
Function Red blood cells transport oxygen from the lungs to all other parts of the body.White blood cells are mainly involved in defending against infection and fighting off foreign invaders in the body.

What Are Red Blood Cells

Red blood cells are important for the human body. They are the second most abundant cell type in the human body after white blood cells. These cells are responsible for oxygen transport to tissues, carrying waste products, and fighting infection.

Red blood cells are the most common type of cell found in the human body that carries oxygen and carbon dioxide to and from each other through circulation. They also help with waste removal.

Red blood cells are most abundant in mammals, finishing up to 10% of total body weight. A red blood cell is about 4 micrometers in diameter and has a life span of 120 days under normal conditions. Red blood cells have a few different kinds of proteins that play key roles in their function, such as hemoglobin which is responsible for carrying oxygen from the lungs to the rest of the body.

The large red blood cell stores around 2.2 million of these cells. Each cell is a little smaller than a pinhead. The cell membrane that surrounds the red blood cell is made up of three layers: an outer layer that acts as a barrier, a middle layer that contains hemoglobin, and an inner layer with the nucleus and mitochondria on its surface.

Red blood cells make up 46% of total blood volume and carry oxygen from the lungs to all parts of the body during respiration. They are about 9 micrometers in diameter and have a lifespan of 120 days

What Are White Blood Cells?

What Are White Blood Cells

White blood cells are a type of cell that is created to protect the body from outside threats. They are mostly found in the lymph nodes, bone marrow, intestines, and spleen.

White blood cells are an essential part of the immune system which is the body’s natural defense against infection. This function is highly important for all living things.

White blood cells can be found in high concentrations in humans during acute infections such as sepsis to ensure the proper function of the immune system.

White blood cells (also known as leukocytes) are a type of cell that forms part of the immune system. They help to protect against infectious diseases and regulate your body’s response to foreign substances in your body. They can be found in the bone marrow, spleen, lymph nodes, and peripheral circulation.

White blood cells (WBC) are cells that are part of the immune system in vertebrates. They are typically found in the bloodstream, lymph, spleen, bone marrow, and thymus.

White blood cells fight against foreign invaders such as bacteria, viruses, parasites by migrating to the disease site and engulfing it. White blood cells help prevent infection or heal a wound.

10 Differences Between Red And White Blood Cells

Life-related: Red and white blood cells are the two types of cells found in mammals. They perform different functions, but they are both vital for maintaining life.

Substances: Red blood cells carry oxygen to the body’s tissues while white blood cells help fight bacteria and other foreign substances. There are many differences between red and white blood cells, including their size, shape, surface proteins, rigidity, location in the bloodstream, and function.

Function: Red blood cells carry oxygen and help keep our bodies alive. White blood cells contain immune cells that fight infection and platelets that help the blood clot. There are also many other types of cells in the bloodstream, such as neutrophils and eosinophils.

Complex: The difference between red and white blood cells is complex and difficult to understand for most people. With this information, we can start to understand what goes on inside our bodies when we see either red or white blood cells.

Carrying Oxygen: Red blood cells are the oxygen-carrying cells of the human body. They are responsible for carrying oxygen around to all parts of the body and for releasing it when needed.

Germs Killing: White blood cells, on the other hand, are responsible for fighting infection in your body. They can also help fight infection by killing off harmful germs and bacteria before they can cause damage.

Benefits: Red blood cells carry oxygen to the body’s cells and allow carbon dioxide to be expelled from them. White blood cells help fight off foreign invaders and infection.

Anti Body: White blood cells help fight off foreign invaders and infection by secreting chemicals that can damage or kill bacteria, viruses, fungi, parasites, cancerous cells, cancer tumors, and some types of cancerous tissue as well as create antibodies to battle foreign pathogens

Ratio: Red blood cells are more common than white blood cells. There are 5-6 times more red blood cells in the human body than white blood cells.

Specification: There is a large difference between these two types of cells, but they have many similarities as well. They both have nuclei, cytoplasm, plasma membranes, mitochondria, ribosomes, and Golgi bodies within them.

Interesting Statistics Or Facts Of Red Blood Cells

1) A red blood cell is the most abundant type of human cells in the human body. It is found mainly in your bone marrow, your spleen, your blood vessels, and your heart. It has a lifespan of about 120 days.

2) Red blood cells are noticeably different from other cells in a variety of ways. You may have heard that red blood cells last up to 3 months, which is about 130 days. However, at the end of this period, they just die and get replaced by new red blood cells.

3) Circulating volume: approximately 5% of the total volume of the human body.

4) Adult human red blood cell life-span: about 120 days in humans.

5) Red Blood Cell Size: 8 microns wide and 6 microns long.

6) Red blood cells (RBCs) are the crucial cells that supply oxygen to the body. They are present in our bloodstream and do not last for more than 120 days.

7) Red blood cells are composed of hemoglobin, which is what gives them their red coloration. Hemoglobin is red because it has an iron atom bonded to a heme group. Red blood cells can live for 120 days without new hemoglobin developing inside them, while platelets can live up to 4 days without new platelet formation outside the cell.

8) The average lifespan of an RBC is 120 days, but they can survive up to 180 days depending on various factors including temperature and lack of oxygenated blood flow in some regions of the body.

9) Red blood cells are usually made up of a nucleus, which contains DNA and ribosomes, and two types of membranes – an inner membrane that separates it from the rest of the body fluid and an outer membrane that is rich in lipid-rich droplets.

10) Red blood cells contain a lot of hemoglobin, a protein that binds with oxygen and carbon dioxide, which give them their red color.

Interesting Statistics Or Facts Of White Blood Cells

1. White blood cells have a lifespan of about three weeks, which is why it takes at least two to three months for a new population to grow.

2. White blood cells can change into one of five different types in the body: white blood cells, lymphocytes, granulocytes, monocytes, and platelets.

3. The number of red blood cells in the human body is around 5 million and there are 16 million total white blood cells in the human body.

4. Humans have around 4 billion red blood cells in their bodies and around 38 trillion white blood cells in their bodies!.

5. The number of granulocytes in the human body is 28 trillion.

6. White blood cells help regulate the water levels in your body by secreting a protein called antidiuretic hormone that helps regulate how much fluid is in your body.

7. Most people have between 5 and 12 million white blood cells in their body at any time, with women having more than men on average due to estrogen levels during pregnancy and childbirth

8. White blood cells release hormones when they die which makes them easier to find in a medical laboratory.

9. White blood cells can be found in your body’s blood, bone marrow, and the fluid surrounding your brain and spinal cord.

10. White blood cells play an important role in defending your body against infection and disease; they can also cause inflammation or an allergic reaction if they become overactive.

Conclusion About The Differences Between Red Blood Cells And White Blood Cells 

Red blood cells and white blood cells are not the same.

White blood cells fight infection and disease while red blood cells carry oxygen. They come in different shapes, sizes, kinds, and colors. However, they both can move through an organism’s body to help with digestion and other tasks.

The summary concludes that red blood cells are large compared to white blood cells due to their function of carrying oxygen throughout the body while white blood cells protect against infection or disease.
