How are red blood cells special for their job?
What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
What are the special features of a red blood cell?
they contain haemoglobin – a red protein that combines with oxygen. they have no nucleus so they can contain more haemoglobin. they are small and flexible so that they can fit through narrow blood vessels. they have a biconcave shape (flattened disc shape) to maximise their surface area for oxygen absorption.
Why is blood red in Short answer?
Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. It’s bright red when the arteries carry it in its oxygen-rich state throughout the body. And it’s still red, but darker now, when it rushes home to the heart through the veins.
How long does a blood cell live?
Red blood cells (erythrocytes) Red blood cells make up almost half of your blood. The lifespan of a red blood cell is around 120 days.
What are the functions of red blood cells?
Your blood has three types of blood cells that carry out different functions. One type of blood cell is a red blood cell (RBC) and its main job is to carry oxygen to the cells of the body, and help it get rid of carbon dioxide.
What is the function of erythrocytes in the body?
Commonly known as red blood cells, erythrocytes are a type of blood cell primarily involved in the transportation of oxygen to body tissues (from the lungs) and carbon dioxide from the tissues to the lungs to be removed from the body.
How are red blood cells responsible for transport of oxygen?
This protein is responsible for the transport of more than 98% of the oxygen, while the rest travels as dissolved molecules through the plasma. The primary functions of red blood cells (RBCs) include carrying oxygen to all parts of the body, binding to hemoglobin, and removing carbon dioxide.
What makes the nucleus of a red blood cell flexible?
They have thin membranes and are elasticated so are flexible when in the blood stream. The ‘dimple’ where the nucleus should be is instead filled with haemoglobin (which carries oxygen), there fore the more room for haemoglobin, the more oxygen can be carried around the body. 234

Which is part of the red blood cell carries oxygen?
The primary function of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body.

Who are the people who need red blood cells?
Patients who benefit most from receiving red blood cells include those with chronic anemia resulting from kidney failure or gastrointestinal bleeding, and those with acute blood loss resulting from trauma. They can also be used to treat blood disorders such as sickle cell disease.
