### body part:

Cortex
* All cortex is laminated, meaning that it consists of distinct layers when seen under a microscope.
* Most cortexes are part of cerebrums.
* Most cortexes produce hormones
  - several steroid hormones
  - serve functions
* Some cortexes have appearances
  - arrangements
  - plant tissue
* contains only parenchyma cells.
* have limitations.
* includes axons
  - cell membranes
  - cytoplasm
  - dendrites
  - nuclei
  - plasma membranes
  - sections
  - vacuoles
* neural structure

Costa
* are structures.
* e includes corpi.

Croup
* Most croup is caused by a virus infection
  - viruses and occasionally by bacteria
* are diseases.
+ Croup, Causes: Viruses :: Respiratory system :: Infectious diseases
  * Most croup is caused by a virus infection. Some people call severe laryngotracheitis croup. This disease is caused by a milder virus. Croup also can be laryngeal diphtheria, bacterial tracheitis, laryngotracheobronchitis, and laryngotracheobronchopneumonitis. These diseases are caused by bacteria and are more severe.

### body part | croup:

Viral croup
* begins with a cold that develops into a bark y ing cough.
* is more common in children less than five years of age
  - preceded by an upper respiratory infection with sore throat

Diaphragm
* are located in vertebrates
  - part of bodies
* body part.
* cause breaths.
* force air.
* have muscles.
* holds cream or jelly that forms a barrier and kills sperm.
  - ground substances
  - ligaments
  - mast cells
  - tendons
* mechanical device
* push air.
* separate chests.

Dilator
* also help women learn to relax the vaginal muscles.
* are body parts
  - drugs
* work best when used early to prevent vaginal shrinkage.

### body part | dilator:

Vasodilator
* Some vasodilators dilate the blood vessels in the lungs and reduce the hypertension.
* are dilators
  - medicine
* cause blood vessels to expand, thereby increasing blood flow.
* complicate blood flow to ischemic tissue by several proposed mechanisms.
* increase the size of blood vessels.
* make it easier for blood to flow and reduce the heart's work load.
* reduce the workload of the heart.
* relax the blood vessels
  - muscles in the blood vessel walls and allow the vessels to dilate
* work by making the arteries throughout the body open up.

### body part:

Duct
* Most ducts are formed by cystic ducts
  - carry bile
* Most ducts carry digestive fluid
  - secretion
  - contain substances
* Most ducts have respiratory tissue
* Most ducts pass through glands
  - prostate glands
* Some ducts associate with structures.
* Some ducts carry bile salt
  - milk
  - urine
  - waste
  - connect pancreases
  - contain enzymes
* Some ducts drain into ureters
  - veins
  - livers
  - nephrons
* Some ducts lead from coeloms
  - esophagi
  - intestines
  - kidneys
  - testes
* are a critical link in home energy efficiency
  - conduits
  - impermeable to the major constituents of milk
  - located in houses
  - part of vascular plants
  - passage
  - the small passages connecting the milk-producing glands, or lobules, to the nipple
  - typically smaller tubes associated with exocrine structures
  - wave-guides which cause constructive and destructive interference of propagating energy
* branch out from the nipple to the interior of the breast, ending in clusters of the lobules.
* can cause radio waves to propagate to anomalously short or long ranges.
  - milk from the lobules after childbirth
* get dirty when holes or gaps in the ductwork permit foreign matter to enter the air ducts.
* lead to the nipple in the center of a dark area of skin called the areola.
* lose air at each joint like a hole in a bucket.
* produce drag, but no downforce.
* supply air.

### body part | duct:

Air duct
* serve as a fertile breeding ground for mold spores.
* serves as a prime breeding ground for mold spores.
