This course provides a comprehensive study of the functional systems that maintain human life and health. Students will explore the intricate mechanisms by which organs and organ systems work together to sustain homeostasis. The course covers the structural and functional relationships of major bodily systems with emphasis on integrated physiological processes.
The digestive system unit examines the complete process of nutrition from ingestion to assimilation. Students learn about the alimentary canal and associated glands, studying mechanical and chemical digestion processes. The course details enzyme action at various sites, absorption mechanisms in different intestinal regions, and the neural and hormonal control of digestive secretions. Common disorders like jaundice and constipation are discussed from a physiological perspective.
The respiratory system section covers the mechanism of breathing, pulmonary gas exchange, and transport of gases in blood. Students analyze the regulation of respiration through neural and chemical controls. The course includes study of lung volumes and capacities with practical applications in understanding respiratory efficiency.
The circulatory system unit examines cardiac cycle, electrical conduction system of the heart, and regulation of cardiac activity. Students learn about blood composition, blood groups, coagulation process, and lymphatic system functions. The course covers blood pressure regulation and common cardiovascular disorders.
The excretory system focuses on kidney structure and function, including urine formation through filtration, reabsorption, and secretion processes. Students study regulation of kidney function by hormonal mechanisms and the role of kidneys in maintaining acid-base balance. Dialysis technology and common renal disorders are discussed.
The movement and locomotion unit covers types of muscles, muscle contraction mechanism at molecular level, and the structure and function of skeletal joints. Students learn about neural control of muscle movement and coordination.
Neural control and coordination examines neuron structure, nerve impulse conduction, synaptic transmission, and central nervous system organization. The course covers sensory reception and processing, with special attention to eye and ear physiology. Reflex action and autonomic nervous system functions are analyzed.
Chemical coordination focuses on endocrine glands, their hormones, functions, and regulatory mechanisms. Students study hormonal action pathways and feedback mechanisms maintaining hormonal balance. Common endocrine disorders are examined.
The course emphasizes clinical correlations throughout, helping students understand physiological principles behind medical conditions. Laboratory components include practical experiments demonstrating physiological principles. Students develop skills in interpreting physiological data, understanding homeostatic mechanisms, and applying knowledge to real-world health scenarios.
This course prepares students for advanced studies in medicine, nursing, and research careers in life sciences. By understanding normal physiological processes, students gain foundation for recognizing and understanding pathological conditions. The integrated approach helps students appreciate the remarkable coordination between different systems that maintains human life.
