<u>Enteric nervous system</u> is the division of the nervous system that innervates the digestive tract, and <u>vegetative nervous system</u> is also called autonomic nervous system.
- The peripheral nervous system's autonomic nervous system controls physiological functions that are carried out automatically, such as digestion, blood pressure, respiration, and sexual desire.
- There are three physically separate divisions in it: enteric, parasympathetic, and sympathetic.
- The enteric nervous system (ENS), a partially autonomous component of the nervous system, is made up of a number of neuronal circuits that regulate immunological and endocrine activity as well as motor and local blood flow.
- The enteric nervous system, which makes up the third division of the autonomic system, is made up of a number of neurons that are integrated into the gastrointestinal tract's and its derivatives' wall.
- This system regulates the secretion and motility of the digestive tract.

- Each thylakoid contain green pigment called chlorophyll that traps sunlight to carry out photosynthesis.
- Chloroplasts is a double membrane bound organelle having its own DNA.
- Chloroplasts are considered as one of the organelles that originated as a result of endosymbiosis of photosynthetic bacteria.
