BIOL 223: Human Anatomy and Physiology

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

Discover the intricacies of the human cardiovascular system, focusing on the heart's blood supply. Understand the unique role of coronary arteries in nourishing the myocardium. Gain insights into the critical vessels that ensure heart health.

Explore the characteristics that distinguish normal cells from cancer cells in this informative video. Learn how normal cells perform specialized functions for overall health, while cancer cells grow uncontrollably. Discover why cancer cells lack differentiation, ignore reproduction control signals, and their connection to the absence of radical scavengers, all leading to their uncontrolled proliferation.

Explore the intricate workings of the immune system's overactive responses, known as hypersensitivity reactions. Learn about the classification into Types I, II, III, and briefly, IV, along with real-world examples. Uncover the mechanisms behind these reactions and their impact on our health.

Explore the lethal impact of cyanide on cellular organelles particularly its devastating effect on mitochondria. Our video sheds light on how cyanide halts ATP production bringing cellular functions to a standstill. Ideal for students and educators seeking a comprehensive view of toxicology and cellular biology.
