Mechanotransduction is how the body senses tension and turns it into stronger, thicker connective tissue, such as tendons and ligaments. Learn more.
Oxidation
Vasodilation

7 Which part of the body’s defense system was disrupted by eating a high-fat diet?

Enzymes that control glutathione
Eating a high-fat diet altered enzymes tied to glutathione, one of the body’s main antioxidants, reducing the cells' ability to handle stress and damage. Learn more.
