Elderly male patient with a history of stomach cancer had to have a tube inserted to his alimentary canal to bypass the esophagus, stomach, and duodenum. He also had his gallbladder remove.
Alimentary canal is placed to nourish the body with nutrients needed by acting as the esophagus, stomach, small and large intestines.
Unhealthy diet, negligence to health, and family history has led to the development of stomach cancer.
Proper mechanical digestion is unable to occur in patient, hence the need for a feeding tube.
Liquefied mixtures of healthy foods are typical when using a feeding tube
Nutrients WITHIN the tube are similar to what you would get from normal food, and are also digested in the same way. Feeding tube contains nutrients you need on a daily basis, including carbohydrates, proteins, fat, vitamins, minerals, and water.
Proper chemical digestion is unable to occur
Feeding tube is placed where chemical and mechanical digestion can occur properly
Feeding tube is lined with nutrients which also helps absorb nutrients from, often times, liquefied food.
The digestion system functions to obtain nutrients from food we consume and expel waste products we no longer need. Important Nutrients the human body needs include: Vitamins, minerals, fats, proteins, carbohydrates, and water.
Organs of the digestive system
Esophagus; beginning of alimentary canal, long tube which transports food chewed and broken down in your mouth, down to your stomach for further digestion.
Stomach; where food is held until it's chemically broken down by enzymes and gastric acids.(Stomach is known as a hollow organ).
4 Main Regions of the stomach
Fundus; located in the upper part of the stomach
Body; known as the main part of the stomach
Cardia; region where the esophagus connects to the stomach
Pylorus; connects the stomach to the duodenum
Small intestine; lies between the stomach and large intestines. Helps with digestion and adsorbs nutrients from food.
3 Main regions of small intestines
Jejunum; middle segment of small intestines
Ileum; attaches to the colon
Duodenum; connects to the stomach
Large Intestine (Colon); connects small intestine to the rectum. Functions in water absorption and turning indigestible food matter into waste.
4 Regions of the colon
The ascending colon; includes cecum and appendix
The transverse colon
The descending colon
Sigmoid colon; 's' shaped region of large intestines.
Rectum; connects the colon to anus, aids in expelling waste products from the body.
Anus; end of digestive tract where stool exits the body.
Enzymes responsible in digestion of nutrients
Gastric Lipase- Initiates digestion of dietary fats in the stomach
Pancreatic Lipase- converts fat globules into fatty acids and glycerol. These act as energy defense molecules used by all cells
Amylase- Breaks down starches and carbohydrates into sugars
Peptidase- Breaks down proteins into amino acids
Organs involved in mechanical digestion
The act of chewing (and swallowing) food in your mouth with your teeth and breaking food down with your tongue.
Peristalsis in the stomach.
Segmentation in the small intestine
Organs involved in chemical digestion
Enzymes in the saliva of the mouth begins the breakdown of carbohydrates
Liver produces bile which helps with digestion and absorption of fats, such as lipids.
Gallbladder stores bile and helps secrete it to the duodenum.
Pancreas produces enzymes that break down proteins, lipids, and carbohydrates. Also produces sodium bicarbonate which neutralizes stomach acids.
