Bladder: 
 The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys, and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and voluntary.

Gallbladder:
The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen. Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver. ... It also drains waste products from the liver into the duodenum, a part of the small intestine.

Esophagus:
The esophagus seems to have only one important function in the body - to carry food, liquids, and saliva from the mouth to the stomach. The stomach then acts as a container to start digestion and pump food and liquids into the intestines in a controlled process

Pharynx:
It is commonly referred to as the throat. The pharynx is part of both the digestive and respiratory systems. For the digestive system, its muscular walls function in the process of swallowing and it serves as a pathway for the movement of food from the mouth to the esophagus.

Salivary glands:
The salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist. It also helps break down carbohydrates (with salivaryamylase, formerly known as ptyalin) and lubricates the passage of food down from the oro-pharynx to the esophagus to the stomach.
