BIO 201: Human Anatomy and Physiology I

Unravel the intricacies of the Autonomic Nervous System (ANS) and its pivotal role in controlling involuntary bodily functions. Differentiate between the sympathetic and parasympathetic systems and their unique contributions. Debunk misconceptions surrounding the ANS's characteristics.

Explore the world of spontaneous reactions, focusing on cellular respiration. Learn how our cells convert glucose into energy-rich ATP, driving vital life functions.

Unpack the process of biological magnification in the food chain and learn why consuming foods from lower trophic levels minimizes toxin exposure. Grasp the implications of human-induced pollutants and the benefits of dietary diversity.

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.

Explore the nature of compounds in chemistry, focusing on potassium chloride (KCl) and its dissociation. Understand the distinctions between salts, acids, bases, and buffers. Dive into the characteristic behaviors of each to identify the true nature of KCl.
