of this practical was to understand how the autonomic nervous system has an effect In the ileum. Through this‚ we can delve deeper by understanding how nerves‚ through the actions Of various neurotransmitters affect the motility of the gastrointesital tract. Furthermore‚ we can investigate The effects of drugs‚ and their uses in replicating effects of autonomic neurotransmitters as well as The way certain drugs can interfere with autonomic neurotransmitters and how they interact with

Homeostasis What is homeostasis? Homeostasis is the mechanism in our body that regulates and maintains a stable and constant environment. This enables our body to respond to changes in the environment around us as. The homeostatic mechanisms in our body‚ observe and monitor conditions and will then make a judgment whether to change the way the body functions is order to adapt to the outside surroundings better. The main organs involved in homeostasis are; the brain‚ liver‚ skin and kidney’s.

The nervous system which is made up of the sensory and control apparatus consisting of a network of nerve cells that control our body functions. There are two main nervous systems: Central Nervous System and the Peripheral Nervous system. Your central nervous system (CNS) consists of your brain and spinal cord.
