Detailed explanation-1: -In sickle cell anemia, some red blood cells look like sickles used to cut wheat. These unusually shaped cells give the disease its name. Sickle cell anemia is one of a group of inherited disorders known as sickle cell disease. It affects the shape of red blood cells, which carry oxygen to all parts of the body.
Detailed explanation-2: -Sickle cell disease (SCD) is a group of inherited red blood cell disorders. Red blood cells contain hemoglobin, a protein that carries oxygen. Healthy red blood cells are round, and they move through small blood vessels to carry oxygen to all parts of the body.
Detailed explanation-3: -Sickle cell disease is a health problem that makes a person’s red blood cells become C-shaped or curved like a sickle instead of round. The curved cells can get stuck in and block small blood vessels. Blood can’t flow normally, which can lead to pain and organ damage.
Detailed explanation-4: -Normally, red blood cells are disc-shaped and flexible enough to move easily through the blood vessels. If you have sickle cell disease, your red blood cells are crescent-or “sickle”-shaped. These cells do not bend or move easily and can block blood flow to the rest of your body.
