BIOL 26138: Biology II

Uncover the fascinating system that nourishes osteocytes in our bones: the osteocyte lacunar-canalicular network. Learn how canaliculi connect these mature bone cells to vital nutrients, ensuring their health even at significant distances from blood vessels.

Discover the body's innate ability to adapt to extreme cold conditions. Learn how the brain orchestrates warming responses like shivering. Grasp the concept of homeostasis in maintaining internal stability.

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 foundational principles of Hutton and Lyell, which shaped Darwin's evolutionary ideas. Understand uniformitarianism, deep time, and geographical patterns that inspired Darwin's theory. Discover how geology influenced biological understanding.

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 composition of the diaphysis in long bones. Learn about the significance of compact bone in providing strength and differentiating it from other bone components.
