BIOL 117: Introductory Physiology

Discover the unique characteristics of the Mammalia class, with a focus on humans. Understand the critical role of molecular oxygen in our survival and the consequences of its absence. Learn how oxygen stands out among other vital factors like food, water, and nitrogen.

Discover the differences between hydrocarbons and other organic molecules. While hydrocarbons contain only carbon and hydrogen, other organic molecules integrate more elements and functional groups. This distinction leads to diverse chemical properties and vital biological functions.

Learn about the role of Erythropoietin (EPO), a natural kidney hormone, in controlling red blood cell production and oxygen transport. Discover how athletes misuse synthetic EPO for performance enhancement, despite the associated health risks.

Grasp the fundamentals of how neurons transmit electrical signals through action potentials. Understand the crucial role of myelination and fiber diameter in efficient nerve impulse conduction. Dive into the comparisons of different nerve fiber types and their properties.

Explore the essential role and composition of blood plasma in our body. Understand how water, as the main component, helps in maintaining vital functions. Learn the importance of plasma balance for overall health insights.

Discover the unique adaptations of C4 and CAM plants in photosynthesis. Understand their evolved strategies to fix carbon efficiently in challenging environments. Dive into nature's remarkable mechanisms of survival and adaptation.
