Sickle cell anemia - Symptoms and causes - Mayo Clinic
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. Red blood cells are usually round and flexible, so they move easily through blood vessels. In sickle cell anemia, some red blood cells are shaped like sickles or crescent moons.

Sickle Cell Disease - What Is Sickle Cell Disease? | NHLBI, NIH
Sickle cell disease is a group of inherited red blood cell disorders that affect hemoglobin, the protein that carries oxygen through the body.

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.

"Scythe" vs. "Sickle" – What's The Difference? |
A scythe is a farming tool with a long, slightly curved blade that’s mounted on a long pole (called a snath ). Real-life versions usually have two shorter hand-sized handles attached to the pole—one in the middle and one at the end. Either way, you have to use two hands to properly wield a scythe. The scythe is used to cut grasses and grains—it’s designed so the blade moves in a plane parallel to the ground.
