Chemotaxis

Chemotaxis is the movement of cells or organisms toward or away from chemical signals in their environment. This process helps cells find food, escape danger, or reach specific locations within the body. For example, immune cells move toward infection sites by detecting signals released by injured tissue or bacteria. Chemotaxis is guided by gradients of chemicals, meaning cells sense differences in concentration and move toward higher or lower levels, depending on their purpose. This targeted movement is essential for processes like immune response, wound healing, and development.
