They're not true cells, they're not "alive" ... they are only bags of chemicals.
so that they can fit through blood vessels
Because they Are so small they can't get out.
well you dont want your blood cells to big or to small the red blood cells are what keeps your blood flowing the correct way so yes red blood cells are life threatening.
blood cells are small and red
the red cell is responsible for carrying oxygen to the cells of the body and taking up carbon dioxide and returning it to the lungs so it can be released from the body. red blood cells a circular and biconcave in shape ,they are are elastic and so can pass through any small capillaries making the blood flow easy They turn red from oxygen reacting with the hemoglobin in them. A sickler's red blood cells are semi-circular.
Red blood cells are too small to contain blood vessels. They are cells and they travel in blood vessels.
Red blood cells are about 2500 nanometers across, and a nanometer is one billionth of a meter across.
yes it is true because when you body grows, trillions of blood cells are made. But sence cells are so small it does not effect you size very much.
Small and red, rich in haemoglobin, carry oxygenated blood to tissues of the body
Red blood cells can be small in size due to conditions such as iron deficiency anemia, thalassemia, or certain genetic disorders. These conditions can affect the production or structure of red blood cells, leading to smaller than normal sizes.
One reason is that cells are so small,is because they are to small to be seen by the naked eye.
llamas are camelids. Camelids can have a small number of nucleated red blood cells. But their red blood cells are elliptical rather than round.
