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

Discover the significance of coronary arteries in heart health, where they branch from, and their role in delivering oxygen-rich blood to the heart muscle. Learn the differences between the ascending aorta, aortic arch, and pulmonary trunk in relation to the coronary arteries.

Explore the intricacies of muscle contraction and the pivotal role played by elements like Calcium, Sodium, Potassium, and Chloride. Learn how Calcium directly triggers contraction by interacting with troponin and actin filaments. A thorough breakdown of each element's unique contribution to our body's movement.
