BIOL 3455: Human Anatomy and Physiology With Lab I

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.

Discover the distinct identity of elements as we clarify the smallest unit that embodies their unique properties. Breaking down options such as electrons, isotopes, and elemental particles, this video offers a clear explanation of why atoms stand out.

Discover how our brain interprets the scent of smoke differently based on context. Compare reactions in an open campfire setting versus an enclosed residence hall. Understand the underlying mechanisms of olfactory fatigue and context-driven alarm responses.

Dive into the biochemistry of haemoglobin, a pivotal protein in red blood cells. We assess key statements about its structure and function, clarifying common misconceptions.

Learn why lipid-soluble signaling molecules like aldosterone only impact specific target cells. We discuss four theories and reveal that intracellular receptors present only in target cells are the key. This video demystifies the unique mechanism behind aldosterone's selective action.

Understand the essence of controlled experiments and the significance of control groups. Unpack the common misconceptions associated with experimental design. Grasp the key factors that make an experiment truly controlled.
