What condition involves crescent-shaped red blood cells affecting the ability to carry oxygen?

• A. Sickle Cell Anemia
• B. Down's Syndrome
• C. Huntington's Disease
• D. Cystic Fibrosis

Answer: (A)

Sickle Cell Anemia is a genetic blood disorder characterized by the production of crescent-shaped red blood cells, also known as sickled cells. These deformed cells are less flexible and can become stuck in small blood vessels, leading to blockage of blood flow. This results in reduced oxygen delivery to various tissues and organs in the body, which can cause pain, fatigue, and serious complications. The sickle-shaped cells also have a shorter lifespan than normal red blood cells, contributing to anemia as the body struggles to replace them. In contrast, the other conditions listed do not involve abnormalities in red blood cell shape or function related to oxygen transport. Down's Syndrome is a chromosomal condition affecting cognitive and physical development, Huntington's Disease is a neurodegenerative genetic disorder, and Cystic Fibrosis is a genetic disorder that affects the lungs and digestive system but does not impact red blood cell morphology.
