APHY 203 typically refers to a course in Anatomy and Physiology II, which is the second part of a two-course sequence that provides a detailed exploration
... [Show More] of the structure and function of the human body. Building upon the foundational knowledge gained in Anatomy and Physiology I (APHY 201) or a similar introductory course, APHY 203 delves deeper into the complexities of human anatomy and physiology. Here's an overview of what is commonly taught in APHY 203:
Cardiovascular System: In APHY 203, students explore the anatomy and physiology of the cardiovascular system, including the structure and function of the heart, blood vessels, and blood. Topics may include cardiac anatomy, cardiac cycle, blood flow through the heart and circulation, blood pressure regulation, and cardiac conduction system.
Respiratory System: The course covers the anatomy and physiology of the respiratory system, including the structure and function of the respiratory tract and lungs. Students learn about pulmonary ventilation, gas exchange (external and internal respiration), respiratory volumes and capacities, respiratory regulation, and common respiratory disorders.
Digestive System: APHY 203 includes an in-depth study of the anatomy and physiology of the digestive system, including the structure and function of the gastrointestinal tract and associated accessory organs. Topics may include ingestion, digestion (mechanical and chemical), absorption, motility, secretion, and regulation of gastrointestinal processes.
Urinary System: Students explore the anatomy and physiology of the urinary system, including the structure and function of the kidneys, ureters, bladder, and urethra. Topics may include renal anatomy, urine formation (filtration, reabsorption, secretion), renal regulation of electrolyte and fluid balance, and kidney function in maintaining homeostasis.
Reproductive System: APHY 203 covers the anatomy and physiology of the male and female reproductive systems, including the structure and function of the reproductive organs and gametogenesis. Topics may include reproductive anatomy, hormonal regulation of reproduction, fertilization, embryonic development, and pregnancy.
Endocrine System: The course explores the anatomy and physiology of the endocrine system, including the structure and function of endocrine glands and hormones. Students learn about hormone synthesis, release, transport, and target cell response, as well as the regulation of endocrine function and feedback mechanisms.
Fluid, Electrolyte, and Acid-Base Balance: APHY 203 includes a study of fluid and electrolyte balance in the body, including mechanisms of water and solute regulation, acid-base balance, and homeostatic mechanisms. Students learn about fluid compartments, osmolarity, electrolyte distribution, and acid-base buffering systems.
Integration of Systems: Throughout the course, students explore how different organ systems interact and coordinate to maintain homeostasis and support overall health and functioning of the body. Emphasis may be placed on the integration of physiological processes and the regulation of body systems.
In addition to lectures, APHY 203 may include laboratory sessions where students have the opportunity to reinforce their understanding of anatomical structures and physiological processes through dissections, experiments, simulations, and other hands-on activities. Overall, APHY 203 provides students with a comprehensive understanding of human anatomy and physiology, preparing them for further studies in health-related fields such as medicine, nursing, allied health, and biomedical research.
