Red blood cells or erythrocytes are specialised to their function in four ways:
- Cytoskeleton: They have unique cytoskeleton proteins which give them their biconcave shape. This increases the surface area comparing to volume which helps to exchange gases easily. It also makes them flexible, which allows them to pass through the tiny capillaries.
- Haemoglobin: Red blood cells are almost entirely filled with haemoglobin, a protein which can bind oxygen and CO2 (but not at the same time).
- No nucleus or mitochondria: This frees up additional space and allows them to carry more haemoglobin.
- Reduction systems: Each haemoglobin molecule carries four iron (Fe) ions. These need to be kept in a reduced state (Fe2+ rather than Fe3+) in order to be able to bind oxygen. Apart from haemoglobin, red blood cells contain a set of enzymes which helps to keep the iron reduced.

What blood part helps the cells perform the organic function of respiration?
Red Blood Cells
Which is a function of the cell membrane in red blood cells?
A function of the cell membrane in red blood cells is to regulate the passage of substances in and out of the cell, such as oxygen and carbon dioxide. This selective permeability helps maintain the cell's internal environment and function.
What does blood carry to the cells of an animal?
In its most basic function, red blood cells act as oxygen-transports for animal cells.
Are all blood cells exactly the same?
No, there are different types of blood cells, each with specific functions. The main types of blood cells are red blood cells, white blood cells, and platelets. They vary in size, shape, and function.
Why is the design of the tuber cells not suitable to perform the function of a cell leaf?
The leaf cells are dorsi-ventrally oriented to capture maximum sunlight for photosynthesis. The tuber cells are clubed togather having very little freesurface area hence not suitable to perform the function of a leaf cell.
Are the only blood cells that function entirely in blood vessels?
The only blood cells that function entirely within the blood vessels are red blood cells.
Is NOT function of white blood cells?
White blood cells do not carry oxygen in the blood.
What is the function of blood in circulatory?
The function of blood in circulatory is to bring oxygen to the cells around the body. Without blood cells would not be able to get oxygen.
Which blood cells take oxygen around the body?
The red blood cells have that function.
What is the function of blood cells in the lungs?
The main function of blood cells in lungs is to carry oxygen and carbon dioxide throughout the body
What is the function of erthrocytes?
Erythrocytes are red blood cells that have the main function of delivering oxygen to cells in the body. Leukocytes are white blood cells that are associated with the immune system.
What blood part helps the cells perform the organic function of respiration?
Red Blood Cells
What is the function of white blood cells in the blood?
to help fight infections
What is the function of white blood cells in blood?
to help fight infections
Is the Destruction of old red blood cells a function of thymus?
No, the destruction of old red blood cells is not a function of the thymus. The thymus is involved in the development and maturation of T cells, a type of white blood cell important for immune function. The spleen and liver are organs responsible for the removal of old red blood cells from the circulation.
Which is a function of the cell membrane in red blood cells?
