BIOL 190: Intro Biology for Health Professions

Explore the similarities and differences between the circulatory systems of amphibians and humans. Understand the distinctions in heart chambers, blood pressure, and where these two species align in their circulatory features.

Explore the vital roles of pharyngeal slits in lancelets and tunicates. Learn how these clefts aid in filter-feeding, capturing food particles, and evolve through different life stages.

This video explores the distinction between innate and learned behaviors in animals. Innate behaviors are inborn and instinctive, while learned behaviors develop through experiences and observations, allowing animals to adapt to their environment and enhance their chances of survival.

Explore the intricacies of nucleic acids, the macromolecules essential to life. Understand the roles of DNA and RNA, and delve into the structure of nucleotides—the fundamental building blocks of these crucial biomolecules.

Discover the precise organization of thin and thick filaments in muscle cells as we debunk misconceptions and highlight the vital role of sarcomeres in muscle contraction.

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.
