BSC 216: Human Anatomy & Physiology II

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 essence of hydrostatic pressure and its significance in capillary beds, examining its relationship with colloid osmotic pressure and how it affects fluid movement in our circulatory system.

Explore the similarities and differences between the circulatory systems of amphibians and humans. Understand the distinctions in heart chambers, blood pressure, and where these two species align in their circulatory features.

Explore the distinctions between aerobic, anaerobic, and non-aerobic exercises. Understand the energy mechanisms driving each type of exercise and their unique health benefits. From jogging and sprinting to golf, discover how each engages the body differently.

Discover the body's innate ability to adapt to extreme cold conditions. Learn how the brain orchestrates warming responses like shivering. Grasp the concept of homeostasis in maintaining internal stability.

Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.
