What is sickle in biology?
Collapse Section. Sickle cell disease is a group of disorders that affects hemoglobin , the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle , or crescent, shape …
What is sickle look like?
Red blood cells usually look like round discs. But in sickle cell disease, they’re shaped like crescent moons, or an old farm tool known as a sickle. These sickle shaped cells get stuck together easily, and block off small blood vessels. When blood can’t get to where it should, it can lead to pain and organ damage.

How do you get sickle cell?
Sickle cell is an inherited disease caused by a defect in a gene.
- A person will be born with sickle cell disease only if two genes are inherited—one from the mother and one from the father.
- A person who inherits just one gene is healthy and said to be a “carrier” of the disease.
What blood type carries sickle cell?
Sickle cell trait (AS) is not a “type” of sickle cell disease. It is an inherited condition in which both hemoglobin A and S are produced in the red blood cells, always more A than S. Individuals with sickle cell trait are generally healthy.
How old can a sickle cell patient live?
Results. Among children and adults with sickle cell anemia (homozygous for sickle hemoglobin), the median age at death was 42 years for males and 48 years for females. Among those with sickle cell-hemoglobin C disease, the median age at death was 60 years for males and 68 years for females.
