BME 311: Introductory Biology 2

Discover how filtration pressure is calculated within our bodies. Explore various options from adding capillary pressures to understanding lymphatic vessel roles. Grasp essential physiology principles as we highlight the accurate method.

Discover the concept of negative feedback loops in biological systems, where balance is maintained by counteracting changes. Explore the four key components: Stimulus, Sensor, Control Center, and Effector, through examples like blood sugar regulation. Uncover how these loops play a crucial role in keeping our body systems in harmony.

Explore the groundbreaking heterotroph hypothesis by Alexander Oparin. This video outlines how the first organisms likely consumed pre-existing organic matter reshaping how we think about the origins of life and evolution

This video explores the distinction between innate and learned behaviors in animals. Innate behaviors are inborn and instinctive, while learned behaviors develop through experiences and observations, allowing animals to adapt to their environment and enhance their chances of survival.

Explore the critical role of phospholipids in forming cell membranes across various organisms. Understand their unique amphipathic properties and their influence on cellular processes, from transport to signaling.

Explore the fascinating interaction between electrical energy charge and materials through the lens of an electroscope. Discover how inserting a conductor between its charged foil sheets changes the charge dynamics leading to an attraction between foil and needle. Understand the roles of conductors insulators and charge induction in this intriguing experiment.
