To get inhaled air to the alveoi for gas exchange
The alveolar duct primarily consists of smooth muscle and elastin fibers but contains minimal connective tissue. Its structure is designed to facilitate the passage of air to the alveoli, where gas exchange occurs. While there is some connective tissue present to provide support, it is not a major component of the alveolar duct's architecture.
cystic duct and the hepatic duct
No, the alveolar duct does not have cartilage. It is a structure within the lungs that connects the respiratory bronchioles to the alveolar sacs where gas exchange occurs. Cartilage is primarily found in the larger airways of the respiratory system to provide structural support and maintain airway patency.

Alveoli are expanded chambers of epithelial tissue which form the gas exchange surfaces of the lungs. Multiple alveoli share a common duct forming alveoli sacs.
Stenson's duct
In pigs, the duct from the gallbladder is called the cystic duct, which merges with the common hepatic duct to form the common bile duct. This common bile duct then carries bile from the liver and gallbladder to the duodenum for digestion.
Hepatic duct is attached with liver. The union of hepatic duct and cystic duct forms common bile duct.
The duct that transports bile from the gallbladder to the common bile duct is called the cystic duct. It is a small tube that connects the gallbladder to the common bile duct, allowing bile produced by the liver and stored in the gallbladder to flow into the small intestine for digestion.
