BIOL 24802: Human Anatomy and Physiology I

Unveil the essential muscles that make breathing possible in this video. Learn why the diaphragm and scalene are crucial players and why other muscles like the trapezius and semispinalis aren't involved in respiration.

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.

Explore the significance of tracking same-age cohorts in population ecology. Learn how it aids in understanding birth and death rates, predicting population trends, and uncover the reasons behind this crucial ecological research practice.

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.

Discover what happens in your body after a hearty meal! Learn about the concept of 'distension' and how nerve cells act as messengers to your control center, orchestrating the digestive process.

Learn about muscle fascicle patterns and their role in human anatomy. Our video zeroes in on the convergent pattern found in the pectoralis major. Compare this with other muscle types like the biceps brachii and gluteus maximus to deepen your anatomical knowledge.
