Red blood cells contain a protein called hemoglobin. Hemoglobin is able to bind to oxygen molecules. Therefore, the presence of hemoglobin the red blood cells makes them capable of carrying oxygen.
Those living at higher altitudes require more oxygen carrying capacity in their blood since the air is less dense - consequently there is less oxygen in each breath of air. To compensate for this, the body tends to produce more red blood cells to carry the available oxygen.
Adequate oxygen-carrying capacity of blood depends on the presence of enough hemoglobin in red blood cells, proper functioning of the lungs to exchange oxygen and carbon dioxide, and efficient circulation of blood throughout the body to deliver oxygen to tissues. Any disruption in these factors can lead to decreased oxygen delivery to cells and tissues.
The primary oxygen-carrying protein found in red blood cells is hemoglobin. Hemoglobin consists of four protein subunits, each containing a heme group that binds to oxygen molecules. This allows red blood cells to transport oxygen from the lungs to tissues throughout the body.
Blood cells do not require oxygen because they lack mitochondria. The transportation of oxygen in the blood is accomplished by red blood cells carrying oxygen molecules bound to hemoglobin and diffusing into surrounding tissues where it is needed.
The disease is called anemia, which can be caused by various factors such as nutritional deficiencies, blood loss, or underlying health conditions affecting the production or function of red blood cells. Anemia can result in symptoms like fatigue, weakness, and pale skin due to decreased oxygen-carrying capacity of the blood.
There are multiple factors effecting oxygen carrying capacity of blood. These include:Iron levels,The number of red blood cells (the less there are the less oxygen carrying capacity).Diseases which may damage either the red blood cells or the haemoglobin which is the component which actually carries the oxygen.Hydration level of the person, the less water, the less blood volume the less capacity to carry oxygen!!
Iron.
Iron is required by the hemoglobin in red blood cells. Hemoglobin carries oxygen to all areas of the body. A lack of dietary iron could decrease the oxygen-carrying capacity of red blood cells, which can lead to anemia.
Red blood cells
Hemoglobin is the oxygen carrying molecule in red blood cells.
Hemoglobin is the oxygen-carrying component in red blood cells. Hemoglobin is a protein that has an iron molecule. Aside from red blood cells, there are white blood cells, which also are important components of the blood.
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen to cells throughout the body. They contain hemoglobin, a protein that binds to oxygen in the lungs and releases it to tissues in need of oxygen.
Erethrocytes
Red blood cells, specifically the protein hemoglobin within red blood cells, is responsible for carrying oxygen in the blood. Hemoglobin binds to oxygen in the lungs and transports it to tissues throughout the body.
Blood cells that are carrying oxygen will appear bright red, while blood cells that are not carrying oxygen will appear darker in color (usually dark red or purplish). This change in color is due to the presence or absence of oxygen-binding molecules like hemoglobin within the red blood cells.
then they are red if they are not carrying oxygen then they are a purple red.
