Question

Describe the pathway that food takes through the digestive system (starting with the mouth and ending with excretion out of the body).

Answer 1

the food begins in the mouth where it is crushed by the teeth and made soft by the saliva and it is swallowed and travels down the oesophagus by peristalsis and then it enters the stomach where it crushed and churned by the stomach walls and stomach acid and bile. after this, the food enters the small intestine where the minerals and nutrients are absorbed by the villi into the blood by diffusion. after this process is complete it travels to the large intestine where water is drawn out of the waste making it dryer. at the end of the large intestine, it enters the anus and is excreted as faeces.

Answer 2

Answer: The process of digestion begins when you chew with your mouth the enzymes in your saliva and your teeth break down the food.Once you swallow the food goes down the esophagus.When the food reaches the end of the esophagus a ringlike muscle called the Lower esophageal splinter relaxes and allows food to go to the stomach.In the stomach the food gets mixed with digestive acids.The stomach then empties the contents into the small intestine.The small intestine mixes food with digestive juices from the pancreas,liver,and intestine,and push the mixture forward for further digestion.The large intestine absorbs water and changes the waste from liquid into stool.The lower end of your large intestine,called the rectum,stores the stool until it’s pushed out of your anus during bowel movement.
