Sickle-shaped red blood cells can become tangled together due to their abnormal shape, which makes them rigid and less flexible compared to normal disc-shaped cells. When these sickle cells travel through small blood vessels, their pointed edges can interlock and form clumps, obstructing blood flow. This can lead to reduced oxygen delivery to tissues and cause pain and other complications associated with sickle cell disease. The tendency to form these tangles can be exacerbated by low oxygen levels, dehydration, or infection.
Because the condition causes the red blood cells to become sickle shaped rather than round.
Abnormal crescent-shaped blood cells are known as sickle cells, which are characteristic of sickle cell disease. This genetic condition causes red blood cells to become rigid and curved, leading to blockages in blood vessels and reduced oxygen delivery to tissues. Sickle cell disease can result in pain, organ damage, and other serious complications.
Sickle-cell anemia.
Sickle cell disease is caused by a mutation in the gene that encodes for hemoglobin, a protein in red blood cells that carries oxygen. This mutation results in the production of abnormal hemoglobin known as hemoglobin S, which causes red blood cells to become sickle-shaped and less flexible.
Crescent.
The mutation that causes sickle cell anemia leads to the production of abnormal hemoglobin, which causes red blood cells to become sickle-shaped. These sickle-shaped cells can block blood vessels, impairing blood flow and leading to episodes of pain, tissue damage, and increased risk of infections.
Spherocytosis
The word is falcate. It means curved like a sickle.
Sickle-cell anemia
A person with two recessive alleles for sickle cell trait has sickle cell anemia. This genetic condition leads to the production of abnormal hemoglobin, causing red blood cells to become sickle-shaped and leading to various health issues.
