There are the double-concave discs without nucleus, containing hemoglobin transfering an oxygen for tissues.
The special molecule in red blood cells is called hemoglobin.
Hemoglobin is found in the red blood cells.
they are white and not red
hemoglobin
In Bone Marrow, where they replace ones that die in the blood. Dead red blood cells sink to the bottom of the blood vessel where they are "cleaned" (eaten) by special cells.
Red blood cells carrie oxegen to the different parts of your body allowing you to function and live.
Red blood cells transport oxygen from the lungs to all the cells in the body. To do so effectively, they have lots of adaptations: Red blood cells contain haemoglobin, which is a molecule that reversibly binds to oxygen. Red blood cells have no nucleus, so that there is more room for haemoglobin in the cell. Red blood cells have a biconcave disc-like shape (it is thinner in the middle than at the edge) which increases the surface area. Red blood cells are very flexible which means they can pass through the narrow capillaries easily.Key word is explain, so must ensure that there is a link between identifying a feature/adaptation of a red blood cell and how this feature allows them to perform a specific function more effectively
Mammals have red blood cells that vary in size for different species. However, llamas are known to have some of the largest red blood cells among mammals, which is a feature that helps them adapt to high altitudes.
Red blood cells are destroyed in the spleen once they have reached the end of their lifespan, which is typically around 120 days. The spleen contains special cells called macrophages that engulf and break down the old red blood cells.
Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
The cells in the bloodstream include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen to tissues, white blood cells help fight infections, and platelets aid in blood clotting.
