### body part | duct:

Bile duct
* Most bile ducts are part of livers
* Some bile ducts carry bile salt
  - lead from livers
* are channels that drain the canaliculi
  - intact, and no florid duct lesions are seen
  - present in normal numbers and are intact
  - scarred and narrowed, ultimately resulting in cirrhosis and liver failure
* carry bile from the liver and gallbladder through the pancreas
  - to the gall bladder for temporary storage
* strictures Blockages to the bile ducts can occur from a variety of causes.

### body part | duct | body part:

Body canaliculus
* A canaliculus duct
* Canaliculi are important.

Bronchial tube
* begin to relax and energy levels increase.
* look a little like tiny, tiny tree branches.

### body part | duct:

Digestive tract
* Most digestive tracts are about as long as a bus.
* Some digestive tracts contain bacteria
  - symbiotic bacteria
  - extend from mouths
* are absent completely
  - body parts
  - organ systems
  - solid objects
* consists of a mouth and a dead-end sac that is branched for absorption.
* shows little modification for bacterial symbionts.
+ Digestion: Digestive system
  * The mixture passes into the small intestine, where tiny bits of food pass into the bloodstream. The food that is still left goes into the large intestine. Finally, waste products leave the body. Digestion usually takes about 18 hours. Food stays in the stomach for about three hours. Most digestive tracts are about as long as a bus.

Lymph vessel
* All lymph vessels contain one-way valves to prevent backflow
  - valves, like the veins, to prevent backflow
* are ducts.

### body part | duct:

Lymphatic vessel
* All lymphatic vessels have valves.
* Most lymphatic vessels contain fluid
  - lymphatic fluid
* Some lymphatic vessels become blood
  - carry lymph
* are similar to veins, but carry lymph instead of blood
  - except that they carry lymph instead of blood
* carry 'lymph', a colorless, watery fluid and white blood cells
  - interstitial tissue fluids back to the bloodstream
  - non-blood fluids in the body to the veins
* comprise a series of segments, separated by valves.
* drain into the thoracic duct, which drains into the left subclavian vein
  - waste products from tissues
* prevent the backflow of the lymph fluid.
* return fluid collected from the tissues to the bloodstream.
* transport the lymph to the different parts of the body.
+ Lymphatic system: Physiology :: Immunology
  * Lymphatic vessels carry 'lymph', a colorless, watery fluid and white blood cells. It comes  from interstitial fluid in the tissues which is squeezed out of the blood vessels. The lymphatic system transports infection-fighting cells called lymphocytes, and is involved in the removal of foreign matter and cell debris by phagocytes. A second function is to transport fats from the small intestine to the blood.

### body part | duct | lymphatic vessel:

Lacteal
* are part of the vertebrate lymphatic system.
* small vessel that returns lymph fluid back to bloodstream.

Mullerian duct
* are progenitors of female accessory structures, uterus, fallopian tubes and vagina.
* atrophies even though no change occurs in the Wolffian duct.
* develop into oviducts, uterus, and vagina.

Umbilical cord
* insert adjacent to each other.
* is embryology
  - inserted on the abdominal wall
* is part of embryos
  - fetuses
* richer source of stem cells than peripheral blood.
* separate in two to three weeks on average.

Wolffian duct
* degenerates because it is deprived of testosterone.
* develop into epididymis, vas deferens, and seminal vesicles
  - male sex organs , and Mullerian ducts develop into female sex organs
* leave outer border of kidneys and run backward.

Epiglottis
* Some epiglottises are part of airways
  - necks
  - tracheae
  - windpipes
* includes corpi
  - lobes
* includes taste buds
