Blood Disorders and Their Impact on Health

The video tutorial covers the composition of blood, including red and white blood cells, platelets, and plasma. It explains blood cell disorders, focusing on thalassemia and leukemia. Thalassemia is caused by genetic mutations affecting haemoglobin production, leading to various health issues. Leukemia, a type of blood cancer, involves abnormal white blood cell production due to DNA mutations. The video also discusses leukemia treatments, such as stem cell transplants, chemotherapy, and radiation therapy.
