didi i explain these two body system right ?

Question

the digestive system starts before when you eat  when you chew your food it can help you break down the food into small little tiny pieces where so that it can be absorbed and takes in nutrients
like carbohydrates, proteins, fats, vitamins, and minerals hen the food is down it is carried down to the oesophagus then to the stomach and each mouthful of food can  takes about six seconds to reach the stomach .it is made up of 3 layers when the food goes down it will go through 
oesophagus, stomach, small intestine, large intestine, and anus. When it reaches the stomach produces hydrochloric acid and gastric juice. The food can stay in the stomach for a bout 5 hours when the enzymes and food goes through the small intestine.

 The respiratory system-
The lungs, airways, throat, mouth, and nasal passages are the respiratory system,we breath in through the moth and nose oxygen is important our body cell will need it for energy and growth air pass down the throat which goes to the trachea and goes to one of the two bronchi in to the lungs. oxygen passes out of the air into the blood, and carbon dioxide passes out of the blood into the air in the alveoli. Which gets rid of the wastes gases.   have i explain it right does it make sense? thank you :) xx

Pretty well.
In the mouth...Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules). 
The oesophagus uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we're upside-down. 
 Food in the stomach that is partly digested and mixed with stomach acids is called chyme. 
After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food. 
 In the large intestine, some of the water and electrolytes (chemicals like sodium) are removed from the food. Many microbes (bacteria like Bacteroides, Lactobacillus ) in the large intestine help in the digestion process. 
The food travels across the abdomen in the transverse colon, goes back down the other side of the body in the descending colon, and then through the sigmoid colon.
The end of the process - Solid waste is then stored in the rectum until it is excreted via the anus. 

Good site for respiratory system...

Yours are pretty good.  All you missed out is the part saliva plays and beneficia; bacteria in the colon
