Sickle cell anemia

Anemia - sickle cell; Hemoglobin SS disease (Hb SS); Sickle cell anemia

Sickle cell disease is a disorder passed down through families. The red blood cells that are normally shaped like a disk take on a sickle or crescent shape. Red blood cells carry oxygen throughout the body.

Red blood cells, sickle cell

Sickle cell anemia is an inherited blood disease in which the red blood cells produce abnormal pigment (hemoglobin). The abnormal hemoglobin causes deformity of the red blood cells into crescent or sickle-shapes, as seen in this photomicrograph.

Red blood cells, normal

This photomicrograph shows normal red blood cells (RBCs) as seen in the microscope after staining.

Red blood cells, multiple sickle cells

Sickle cell anemia is an inherited disorder in which abnormal hemoglobin (the red pigment inside red blood cells) is produced. The abnormal hemoglobin causes red blood cells to assume a sickle shape, like the ones seen in this photomicrograph.

Red blood cells, sickle cells

These crescent or sickle-shaped red blood cells (RBCs) are present with Sickle cell anemia, and stand out clearly against the normal round RBCs. These abnormally shaped cells may become entangled and block blood flow in the small blood vessels (capillaries).

Red blood cells, sickle and pappenheimer

This photomicrograph of red blood cells (RBCs) shows both sickle-shaped and pappenheimer bodies.

Formed elements of blood

Blood transports oxygen and nutrients to body tissues and returns waste and carbon dioxide. Blood distributes nearly everything that is carried from one area in the body to another place within the body. For example, blood transports hormones from endocrine organs to their target organs and tissues. Blood helps maintain body temperature and normal pH levels in body tissues. The protective functions of blood include clot formation and the prevention of infection.

Blood cells

Blood is comprised of red blood cells, platelets, and various white blood cells.
