Mitosis is a type of cell division that results in two identical daughter cells. It consists of several phases: prophase, metaphase, anaphase, and telophase. During prophase, chromosomes condense and the nuclear envelope breaks down. In metaphase, chromosomes align at the cell equator. Anaphase involves the separation of sister chromatids. Telophase includes the formation of two new nuclei.
The digestive system starts with the mouth where food is chewed. Food moves down the esophagus to the stomach. The stomach breaks down food with acids and enzymes. Nutrients are absorbed in the small intestine. Waste products are expelled through the large intestine and rectum.
