PHYS 612: Principles of Human Physiology

Discover which metabolic pathway is the heavyweight champion of ATP production. We'll evaluate contenders like lactic acid fermentation, the Krebs cycle, and more to determine the top ATP generator.

Discover the pivotal role of decomposers and detritivores in forest ecosystems. Understand the catastrophic consequences of their absence, from biomass accumulation to biodiversity loss. Learn how these unsung heroes maintain forest health and sustainability.

Learn about the critical roles of the epiglottis and glottis in our respiratory and digestive systems. Understand how the epiglottis acts as a protective gate during swallowing, while the glottis facilitates sound production. Together, they ensure safe breathing and swallowing.

Unlock the world of pathogens, the microorganisms causing diseases. Grasp how they invade, colonize, and adversely affect host organisms. Learn about prevention strategies to mitigate their harmful impacts.

Discover the fundamentals of the respiratory system and the primary muscle behind inspiration. This video breaks down the physiological process of breathing, the key role of the diaphragm, and why other muscles don't initiate breathing.

Unlock the secrets of ATP's essential role in powering life's processes. Discover why ATP is a specialized molecule that stores energy for your cells. Learn how to differentiate between common misconceptions and the real function of ATP.
