Abstract
The human body consists of interconnected systems that ensure movement, protection, regulation, and waste elimination. The musculoskeletal system provides structural support and enables mobility, while the immune system defends against infections and diseases. The endocrine system regulates vital functions through hormone secretion, influencing metabolism, growth, and reproduction. The excretory system removes waste, maintaining internal balance and homeostasis. Disorders affecting these systems, such as osteoporosis, autoimmune diseases, hormonal imbalances, and kidney disease, can significantly impact health. Understanding their functions and interactions is essential for disease prevention and effective medical interventions.
