What characteristics of red blood cells help them perform their function?

Answer 1

Red blood cells (RBC) are roundly shaped and have an indent in the middle (like a donut) but no hole. The indent is to increase the surface area of the RBC, thus, making the RBC highly efficient. The function of a RBC is to carry oxygen and other needed nutrients to specific areas of the human body, also is certain parts of the body, carry waste from an area to the liver.

Answer 2

Population and size. The red blood cells are used to carry oxygen to all parts of the body. So, the size of the blood cells and the number or population of the blood cells help carry the MOST oxygen possible to all parts of the body.

Answer 3

Three attributes of red blood cells are:

1. The red blood cells contain hemoglobin which binds oxygen to be carried to the cells, and also similar chemicals that absorb carbon dioxide to be taken from the body.
2. They change shape easily, without breaking, to fit through small capillaries and reach each cell.
3. Their narrow disc shape provides a high ratio of surface area to volume, which improves their interaction with other cells.

Answer 4

1. contain haemoglobin

2. their biconcave disc-shape provide high ratio of surface area to volume, which improve their interactive with other cell

3. no nucleus which provide them more 'room' to carry oxygen

Answer 5

Red blood cells have several different characteristics. They have a strange shape, have no nucleus, can change shape, and contain hemoglobin.
