it blocks other blood cells
Sickle cell disease is an inherited blood disorder that affects red blood cells.
Sickle cell anemia primarily affects the circulatory system and the immune system. The abnormal sickle-shaped red blood cells can block blood vessels, leading to complications such as pain episodes, organ damage, and an increased risk of infections.
because they can
"Sickle cells" refers to an abnormal shape (rather like a sickle) of red blood cells. Red blood cells in humans do not have a nucleus.
Sickle cell disease primarily affects the red blood cells, causing them to become rigid and sickle-shaped, which can lead to blockages in blood vessels, leading to tissue damage and pain. Over time, this can affect various organs in the body, including the spleen, kidneys, lungs, and brain. Complications can also arise in the bones, eyes, and skin.
Information pertaining to Sickle Cell Disease can be obtained at your local doctors office, hospital, library or a reputable online source. Sickle Cell Disease is a disorder that effects a persons' red blood cells. Red blood cells provide oxygen to vital organs.
Hormones in the bloodstream are able to affect target cells/organs and not other cells/organs because of selective permeability. This means that hormones are only able to pass through the cell membrane of certain cells and organs, and not through the cell membrane of other cells and organs. The cell membrane of the target cells and organs are specialized to allow the hormones to pass through, while the cell membrane of other cells and organs are not specialized and are therefore impermeable to the hormones. This is due to the presence of receptor proteins on the cell membrane of the target cells and organs. These receptor proteins can bind to the hormones and facilitate their entry into the cell. Since these receptor proteins are not present on the cell membrane of other cells and organs, the hormones are unable to bind to them and therefore unable to cross the cell membrane. In addition, hormones can be broken down by enzymes in the bloodstream, which means they can’t reach their target cells and organs if they are exposed to the enzymes. This further ensures that hormones only affect the target cells and organs, and not other cells and organs. In summary, hormones in the bloodstream are able to affect target cells and organs and not other cells and organs because of selective permeability and the presence of receptor proteins on the cell membrane of the target cells and organs. Other cells and organs do not have these specialized receptor proteins and therefore cannot be affected by the hormones.
Folic acid helps the body make red blood cells and can improve the symptoms of anemia by supporting the production of healthy red blood cells. However, folic acid supplements will not directly affect the underlying cause of sickle cell anemia, which is a genetic disorder affecting hemoglobin.
Sickle cells are also less flexible and stickier than normal red blood cells
