TRACHEA (WIND PIPE)
It is 10-12 cm long tube with 2-3 cm diameter which arises from larynx and passes upto middle of thorax. Trachea is supported by 16-20 C-shaped incompleted cartilaginous rings and lined by ciliated pseudostratified mucous epithelium.
BRONCHI
Trachea divides into right and left primary bronchi. Left bronchus is about 5 cm long while right bronchus is only 2.5 cm long. Right bronchus almost directly enters the right lung. Infection of right lung is more common due to this.
Inside the lung, the primary bronchus divides into secondary bronchi, secondary bronchi into segmental bronchi and latter into bronchioles. All bronchi are lined by ciliated and mucus secreting pseudostratified epithelium and supported by incomplete cartilaginous rings.

Salivary glands and its ducts
PASS - So Rude Why
PArotid - Stensen Duct
Sublingual - Rivinus Duct
Submandibular - Wharton Duct
Parotid glands: These are the largest salivary glands. They
lie on the sides of the face, just below and in front of ears. Viral infection of parotid glands causing swelling and pain, is the disease called mumps.
Sublingual glands: These lie under the front part of the tongue
Submaxillary glands: These lie at the angles of the lower jaw. The submaxillary ducts, also known as wharton’s ducts open under the tongue.

The exocrine part of the pancreas consists of rounded lobules (acini) that secretes with pH 8.4. About 500-800 ml of pancreatic juice is secreted out per day.
The pancreatic juice contains inactive enzymes- trypsinogen, chymotrypsinogen, procarboxypeptidases, amylases, lipases and nucleases.

E Enterocrinine
C Cholecystokinin
A- Duocrinin -
Stimulate Brunner’s gland to secrete mucus
B- Enterogastrone
it inhibits gastric movements and secretions, possibly by blocking the production or activity of gastrin, Enterogastrone may slow down stomach emptying by reducing the amount of acid produced.
C - Secretin -
increase in the secretion of pancreatic juice & bile from liver.Secretin also inhibits the secretion of gastrin, which triggers the initial release of hydrochloric acid into the stomach, and delays gastric emptying.
