Anatomy of the human body

The human body is a complex, interconnected system made up of bones, muscles, organs, and tissues. Bones form the framework, protecting organs and providing structure. Muscles enable movement by contracting and relaxing. Organs like the heart, lungs, liver, and kidneys perform vital functions such as pumping blood, breathing, detoxifying, and filtering blood. The nervous system (brain, spinal cord, nerves) controls and coordinates these activities. The cardiovascular system delivers oxygen and nutrients via blood, while the immune system defends against illness. Together, these parts work seamlessly to maintain health, growth, and activity.
