A cell is the basic unit of structure and function for all life, and although there are many different forms of specialized cells (such as neurons, epithelial cells, muscle cells, etc.), at the most basic level cell biology there are only two true cell...
Beneficial microbes found on and in the human body
By: Tami Port MS
Within the womb, a baby’s body is axenic, meaning that the uterus is sterile and free of microbes, but soon after birth, the newborn becomes colonized by microbes, most of which are beneficial to human health. These microbes are called normal flora or normal...
