NRSE/NURS 1310: Anatomy and Physiology II

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.

Discover the concept of adaptation in this video, where we evaluate four scenarios to determine which represents a heritable trait enhancing an organism's survival in its environment. Learn how the webbed feet of a duck exemplify a true adaptation, enabling it to thrive in its habitat.

Discover how humans adapt to cold environments through thermoregulation processes. Understand the body's heat conservation and generation mechanisms. Learn why certain physiological responses occur in cold conditions.

Explore the influence of atmospheric pressure in our body's functions, particularly its essential role in pulmonary ventilation or the breathing process.

Explore the indispensable role of decomposers in ecosystems. Understand their impact on nutrient cycling, energy flow, and ecological balance. Realize what Earth would face without these vital organisms.

Discover the distinctions between mixtures and solutions in chemistry. Through everyday examples and a visual aid, grasp the relationship between these two concepts. Comprehend how mixtures and solutions are intertwined, yet uniquely different.
