Description: It is a hollow, muscular tube that carries food and liquid from the pharynx to the stomach.
Function: It functions primarily as a transport tube that directs the progression of food and fluids from the mouth to the stomach.
Location: It is located in the center of your chest in an area called the mediastinum and lies behind your windpipe (trachea) and in front of your spine.
Description: It is a long, tube-like organ that is connected to the small intestine at one end and the anus at the other. It includes the cecum, colon, rectum, and anal canal.
Function: Its function includes absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.
Location: It is located in the lower abdominal cavity from your waist down.
Description: The gallbladder is a small pouch, hollow organ with a pear shape that sits just under the liver.
Function: Its main function is to store bile until it’s needed for digestion. It also concentrates bile, and, when stimulated to contract, it ejects bile into the lumen of the small intestine.
Location: It is located in the upper right part of your abdomen (belly) and sits just under your liver.
Description: It is the largest solid organ in the body. It is shaped like a cone and has a dark reddish-brown color and weighs about 3 pounds.
Function: It removes toxins from the body’s blood supply, maintains healthy blood sugar levels, regulates blood clotting, and performs hundreds of other vital functions.
Location: It is located beneath the rib cage in the right upper abdomen. The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm, and on top of the stomach, right kidney, and intestines.
Description: It is a muscular, hollow, J-shaped organ that receives food from the esophagus and digests them.
Function: Its primary function is to digest food and send it to your small intestine. It also temporarily stores food as well as secretes acid and enzyme that helps break down food.
Location: It sits in your upper abdomen on the left side of your body.
Description: It is the final straight portion of the large intestine that connects the colon to the anus. It is also where feces accumulate just prior to discharge.
Function: It plays a key role in the defecation mechanism. Its job is to receive waste from the colon and store it until it passes out of the body through the anus.
Location: It is located in the lower part of the large intestine that connects to the sigmoid colon.
Description: The small intestine or small bowel is a long, narrow, folded, or coiled tube extending from the stomach to the large intestine. It is where most of the absorption of nutrients from food takes place.
Function: The principal function of the small intestine is to break down food, absorb nutrients needed for the body, and get rid of unnecessary components.
Location: It is coiled inside the lower abdominal cavity beneath the stomach.
Description: It is a long, flat gland that lies in the abdomen behind the stomach. It produces enzymes that are released into the small intestine to help with digestion.
Function: It plays an essential role in converting the food we eat into fuel for the body’s cells. It also helps in digestion and regulates blood sugar.
Location: It is located behind the stomach in the upper left abdomen.

2. Large Intestine
Description: It is a long, tube-like organ that is connected to the small intestine at one end and the anus at the other. It includes the cecum, colon, rectum, and anal canal.

5. Stomach
Description: It is a muscular, hollow, J-shaped organ that receives food from the esophagus and digests them.
Function: Its primary function is to digest food and send it to your small intestine. It also temporarily stores food as well as secretes acid and enzyme that helps break down food.
Location: It sits in your upper abdomen on the left side of your body.
6. Salivary Glands
Description: They are exocrine glands positioned around the oral cavity and secrete their salivary contents into the mouth.
Function: They function to help keep the oral mucosa protected and lubricated. It also plays an important role in digestion because they make saliva.
Location: They are located in the mouth.
7. Pharynx
Description: It is commonly called the throat. It is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra.
Function: It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.
Location: The pharynx is found in the middle of the neck, behind the mouth and nasal cavity, and above the esophagus and trachea.
8. Rectum
Description: It is the final straight portion of the large intestine that connects the colon to the anus. It is also where feces accumulate just prior to discharge.
Function: It plays a key role in the defecation mechanism. Its job is to receive waste from the colon and store it until it passes out of the body through the anus.
