List and describe three disorders involving \(\mathrm{RBCs}\), three disorders involving \(\mathrm{WBCs}\), and two disorders involving platelets. (pages \(121,123,\) and 125 )

Three disorders involving RBCs are: 1. Anemia: a condition resulting from a lack of healthy red blood cells, leading to fatigue, weakness, and pale skin. 2. Sickle cell disease: an inherited disorder causing red blood cells to become sickle-shaped, leading to pain, infections, and organ damage. 3. Polycythemia vera: a slow-growing blood cancer causing overproduction of red blood cells, resulting in increased blood volume and thickness. Three disorders involving WBCs are: 1. Leukemia: a cancer affecting white blood cells, causing an abnormally high number of immature white blood cells and reducing immune system efficiency. 2. Lymphoma: a cancer that begins in lymphocytes, with two main types being Hodgkin and non-Hodgkin lymphoma. 3. Neutropenia: a condition with low neutrophil count, making individuals more susceptible to infections. Two disorders involving platelets are: 1. Thrombocytopenia: a disorder characterized by a low number of platelets, leading to easy bruising and bleeding. 2. Hemophilia: an inherited genetic disorder causing blood to not clot properly due to a defect in clotting factors, leading to frequent and prolonged bleeding.
