BIOL 047: Human Physiology & Anatomy I

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.

Discover the fundamentals of the respiratory system and the primary muscle behind inspiration. This video breaks down the physiological process of breathing, the key role of the diaphragm, and why other muscles don't initiate breathing.

Discover the complex roles of osteogenic cells and their differentiation into bone-related cell types like osteoblasts, osteoclasts, and more. This video will also reveal the surprising origin of osteoclasts, setting them apart from their bone cell counterparts.

Discover the debate between Intelligent Design (ID) and evolutionary science as they clash over the complexity of biochemical pathways in nature. Explore the concept of guided vs. unguided evolution and how diverse pathways challenge the ID perspective.

Explore the distinctions between aerobic, anaerobic, and non-aerobic exercises. Understand the energy mechanisms driving each type of exercise and their unique health benefits. From jogging and sprinting to golf, discover how each engages the body differently.

Discover the essence of hydrostatic pressure and its significance in capillary beds, examining its relationship with colloid osmotic pressure and how it affects fluid movement in our circulatory system.
