BIOL 2240: Intro to Human Physiology

This video traces the evolution of genetic understanding, beginning with Mendel's foundational pea plant experiments, which birthed basic inheritance laws. It delves into complexities like co-dominance, incomplete dominance, and polygenic inheritance. Highlighting the integral role of DNA, it explains its structure and replication, shedding light on mutations. The narrative underscores the interplay of genes with the environment, introducing epigenetics and the myriad ways genes express, shaping

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.

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.

Explore the multifaceted roles of the skin, from protective barrier functions to sensory reception. Understand the distinction between the epidermal and dermal layers. Appreciate the comprehensive functionalities of the integumentary system.

Understand the essence of controlled experiments and the significance of control groups. Unpack the common misconceptions associated with experimental design. Grasp the key factors that make an experiment truly controlled.

Discover what sets muscle cells apart from nerve cells in the complex world of cellular biology. Our video zeroes in on gene expression explaining how it's the key difference between these two cell types. Equip yourself with the knowledge to better understand cellular function and diversity.
