2. What are the 5 sense organs? Skin, Nose, Tongue, Eyes, Ears

3. Pick 2 senses and explain how the sense organ detects that particular sense: Touch(the body): This is done by the nerve endings in your body sending messages to the brain and this is how we can feel things.

Smell(the nose): The nose is filled with mucose membranes that have smell receptors connected to nerves. The smell receptors and the vapour molecules work together and transmit these sensations to the brain and that is how we are able to smell.

The Digestive system

The digestive system is made of many differnt organs all some how connected together, starting from your mouth where the food first enters the body, all the way to your anus where unnecessary waste leaves the body.

The organs that make up the digestive system are the mouth, oesphagus, stomech, small intestine, large intestine and the anus. The process of digestion all starts in the mouth where the food is broken down physically (by chewing) and chemically (by the saliva.) After the food has been broken down enough the food is pushed down the oesophagus. The muscles in the oesophagus help the food to get pushed down. The food then enters the stomech. The stomech is like a bag where partly digested food is stored and broken down even more with the acid in the stomech. The food then enters the small intestine where most of the food is digested. That foods goodness then gets absorbed into the blood. The food that can not be absorbed enters through the apendix then goes through the large intestine, where most of the water and salt is removed. Finally the semi- solid food gets stored in the rectum and before it is excreted from the anus. The digestive system is very important and keeping it healthy is crucial!! smoking can cause alcers in the stomech, Alcohol is dangerous to the digestive system if consumed to much, as it can cause internal bleeding, bad acid reflux and puts you at risk of cancerous tumors in the organs.However healthy diets are recommended to keep a healthy digestive system.
