=Why are red blood cells so important= toc

Water is very important to the body we all need it as humans a lack of water to the body can cause dehydration this is just like Red blood cells. Red blood cells are vital to the human body red blood cells give energy to the other cells. Red blood cells also give oxygen to all the tissues without Red blood cells giving oxygen to our tissues the human bodys risk of dying skyrockets.

Cells make up tissues and tissues make up organs and organ systems. The human body cannot survive without red blood cells. The red blood cells transports oxygen to the tissues. Without blood cells transporting oxygen to the tissues the tissues cannot function correctly and will die eventually. Red blood cells carry a substance called hemoglobin. Hemoglobin consists of iron and protein with the red blood cells.

Anemia is an illness caused by the lack of iron. This can be caused by **insufficient[ insufficient meaning less]** amounts of red blood cells and hemoglobin.

Blood donations are very important when people get into **traumatic[ traumatic meaning very dangerous]** accidents that result in blood loss or have illnesses where their circulation is affected. Red blood cells help to improve circulation, oxygenation, and health.

=The life of a red blood cell=



Red blood cells have a short lifespan. They can survive up to about 120 days. Red blood cells are produced in red bone marrow. Many bones produce red blood cells such as: thoar c ic,vertebrae,cranial, femur, and humerus.

In the average adult human body, the blood carries about 25 trillion red blood cells. The body has to be very efficient because it replaces the red blood cells at a rate of approximately 3 million per second.

When the blood cell gets to this point it starts to wear down especially the membrane. When the blood cells are being removed and filtered they can be removed by the spleen, bone marrow, and the liver. When this process is going on, a new blood cell is already being produced in the bone marrow.

=Hemoglobin=

Red blood cells (erythrocytes) have a nucleus, which is the control center. The main **function[ function meaning its job]** of red blood cells in the body is to transport oxygen and nutrients throughout the circulatory system. Red blood cells also transport carbon dioxide from cells when nutrients are broken down.

Red blood cells also carry the substance hemoglobin which is made of protein and iron. When Hemoglobin binds to oxygen, it gives the red blood cells the ability to carry and circulate the oxygen and nutrients.

The protein and iron hemoglobin carries is important in preventing the illness anemia, which is a lack of iron nutrient. Without hemoglobin and red blood cells, our body would not be able to survive.

=The amount of red blood cells in our body=

Most adults have 20-35 trillion red blood cells. The amount varies depending on gender, age, and illness. Oxygen and nutrients are most important for the human body to survive. The human body needs plenty of red blood cells to carry these **necessities[ necessities meaning essential]** through the circulatory system.

Also, geographic location can influence the supply of blood cells in the body. A person living in a higher altitude produces more red blood cells because the air is thinner and has less oxygen. If there is a lack of oxygen in the environment, the body has to **compensate[ compensate meaning recoup]**.

The body’s response is to signal vital blood producing organs to create more red blood cells to help provide the body with enough oxygen and nutrients.

=How big are red blood cells=

Red blood cells are roughly eight micrometers long. These blood cells are very flexible because of their donut-like shape. Being thin towards the center and thicker towards the outside allows the blood cells to bend and travel freely throughout the body’s vessels.

Red blood cells can be very important in many ways especially delivering oxygen to the tissues. This is why Red blood cells are vital and important in many ways. I believe that Red blood cells are one of the most important cells of all.
