BISC 276010: Human Physiology

Learn about the critical roles of the epiglottis and glottis in our respiratory and digestive systems. Understand how the epiglottis acts as a protective gate during swallowing, while the glottis facilitates sound production. Together, they ensure safe breathing and swallowing.

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.

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

Explore the intricate layers of organization in the human body. From molecules to the complete organism, understand the sequential formation of our biological structure. Uncover the reasons behind incorrect hierarchical interpretations.

Discover the science behind thermoregulation, focusing on endotherms and ectotherms. Understand how internal metabolic processes distinguish endotherms, while ectotherms rely on environmental factors. Highlighting the adaptations each group has evolved to thrive in their habitats.

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.
