Red blood cells are typically round and biconcave in shape, allowing for a larger surface area for the exchange of gases such as oxygen and carbon dioxide. The other cell types listed are not typically circular in shape. Smooth muscle cells are elongated and spindle-shaped, sperm cells have a flagellum and an elongated shape with a pointed head, neurons have a varying shape depending on their location in the body and function, and columnar epithelium cells are tall and rectangular in shape.
