Red blood cells (RBCs) are mature cells without a nucleus or organelles that carry oxygen from the lungs to the body tissues. RBCs are made in the bone marrow and circulate in the blood for about 120 days before being taken out of circulation and broken down by the spleen and liver.

What makes the RBC red?
Red blood cells (RBCs) contain a protein called hemoglobin, which binds to oxygen and gives them their red color. When RBCs are oxygenated, they appear brighter red, and when deoxygenated, they appear darker red. This is why blood in arteries, where oxygen is bound to hemoglobin, appears brighter red compared to blood in veins.
Main function of RBc?
The main function of red blood cells (RBCs) is to transport oxygen from the lungs to the body's tissues and carbon dioxide back to the lungs for exhalation. This is achieved through the use of hemoglobin, a protein that binds to oxygen and carbon dioxide. RBCs also play a role in maintaining the pH balance of the blood.
Is a general term for a condition in which RBCs do not carry enough oxygen to the tissues.?
Anemia is a general term for a condition in which red blood cells do not carry enough oxygen to the tissues. This can be due to various factors such as low iron levels, vitamin deficiencies, chronic diseases, or blood loss. Symptoms of anemia can include fatigue, weakness, and shortness of breath.
What tube color for RBC?
The tube color for testing red blood cells (RBCs) is typically purple, which corresponds to a tube containing the anticoagulant ethylenediaminetetraacetic acid (EDTA). This additive helps to prevent clotting and preserve the integrity of the RBCs for analysis.
What is the effect of RBC when put it in chloroform?
Chloroform can cause hemolysis of red blood cells (RBCs), leading to the release of hemoglobin. This process is due to the disruption of the cell membrane by chloroform. Ultimately, the RBCs will lyse and release their contents into the surrounding solution.
Where do rbc mature?
Red blood cells (RBCs) mature in the bone marrow. Stem cells in the bone marrow differentiate and develop into mature RBCs under the influence of various growth factors and hormones. Once they are fully mature, RBCs are released into the bloodstream to carry oxygen throughout the body.
How do mature RBCs differ from other cells?
Mature red blood cells (RBCs) lack a nucleus and organelles such as mitochondria, which other cells possess. This allows RBCs to have more space to carry oxygen efficiently. Additionally, RBCs are shaped as biconcave discs to maximize surface area for oxygen and carbon dioxide exchange.
Whtat is the name for blood that has oxygen and is the color red?
It is actually the name given to the molecule found in the RBCs that is carrying oxygen. It is called oxyhemoglobin.
What does blood leaving the left side of the heart carry to the body?
When blood leaves the lungs the RBCs are carrying oxygen to be delivered to the tissues of the body.
Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin?
Anemic hypoxia reflects poor oxygen delivery due to too few red blood cells (RBCs) or from RBCs that contain abnormal or too little hemoglobin. This leads to reduced oxygen-carrying capacity in the blood, resulting in inadequate oxygen reaching the body's tissues and cells.
Why not present nucleas in red blood cell?
Red blood cells (RBCs) lack a nucleus to maximize their capacity for carrying oxygen. The absence of a nucleus allows for more space to accommodate hemoglobin, the protein responsible for oxygen transport. This adaptation enhances the efficiency of RBCs in delivering oxygen to tissues throughout the body. Additionally, the lack of a nucleus prevents RBCs from dividing, which is suited to their specific role in the circulatory system.
What three traits of red blood cells make it better suited to its function of carrying oxygen?
Red blood cells (RBCs) have a biconcave shape, which increases their surface area for oxygen absorption and allows them to easily navigate through narrow capillaries. They contain hemoglobin, a protein that binds oxygen efficiently, enabling effective transport throughout the body. Additionally, RBCs lack nuclei and organelles, maximizing space for hemoglobin and enhancing their oxygen-carrying capacity. These traits collectively optimize their function in delivering oxygen to tissues.
Why does a patient's oxygen levels fall as a result of red blood cells?
If the patient blood levels fall (maybe due to hemorrhage), the oxygen that the RBCs are carrying is lost with the blood. The person will feel 'out of breath'.
Does mature RBCs rely on anaerobic glycolysis?
Yes, mature red blood cells primarily rely on anaerobic glycolysis for energy metabolism, as they lack mitochondria which are required for aerobic metabolism. Glycolysis allows them to produce ATP efficiently in the absence of oxygen.
Why can't red blood cells produce repair enzymes?
Red blood cells lack a nucleus and organelles, including repair enzymes, because they are specialized for carrying oxygen. Their main function is gas exchange, and the absence of a nucleus allows for more space to accommodate hemoglobin molecules, increasing their oxygen-carrying capacity.
How does RBC anucleate condition affect its lifespan?
The lack of a nucleus in red blood cells (RBCs) means they cannot repair themselves or synthesize new proteins. As a result, RBCs have a limited lifespan of about 120 days before they are removed by the spleen and liver. This anucleate condition allows RBCs to efficiently transport oxygen without the burden of carrying a nucleus.
What happens to the nucleus of a mature RBC?
Mature red blood cells (RBCs) have no nucleus as it is expelled during the final stages of development in the bone marrow. This lack of a nucleus allows the RBCs to contain more hemoglobin, enabling them to efficiently transport oxygen throughout the body.
