### lipids:

Prostaglandin
* Aggregating platelets release arachidonic acid, which prostaglandin precursor.
* Most prostaglandins have nothing to do with the prostate.
* Some prostaglandins can cause blood vessels to constrict, or narrow
  - cause inflammation, others work against it
  - intensify the inflammatory response while others reduce it
  - potentiate the increase in vascular permeability caused by other compounds
* act in the reproductive system and in the immune system.
* acts as a stimulators to the muscle tissue within the uterus.
* also deliver and strengthen pain signals and induce inflammation
  - promote inflammation and pain in certain diseases and after injury
* alter extracellular matrix adjacent to human ciliary muscle cells in vitro.
* analog A modification of a naturally ocurring substance called a prostaglandin.
* are a group of highly reactive compounds made from polyunsaturated fatty acids
  - proteins that cause pain
  - part of a cascade of factors leading to inflammation
  - essential to the proper functioning of all organs and of the reproductive system
  - fatty acid-based chemicals that are made in most of the tissues of the body
* are fatty acids that behave in many ways like hormones
  - can be found in every cell of the body
  - hormone like molecules that regulate a variety of body functions
  - hormone-like compounds that stimulate the uterus and affect blood vessels
* are hormone-like substances that are found in every body cell
  - help keep blood vessels dilated
  - influence the elasticity of blood vessels
  - regulate blood pressure and clotting
* are hormones naturally present in the uterus that cause contractions during labour
  - that cause uterine contractions
  - local hormones
  - modulators of inflammation
* are one of the agents released by the body with inflammation
  - mediators of the inflammatory response
  - oxygenated metabolites of certain polyunsaturated fatty acids
  - proteins some of which can cause inflammation
  - secreted by many body tissues and perform a variety of functions
  - short lived, hormone like substances derived from essential fats in the diet
* are substances that have a myriad of effects in the body
  - which cause contractions in the uterine and intestinal muscles
* are the natural hormones in the body responsible for inflammation and swelling
  - primary mediators of inflammation and swelling
* can also activate specific pathways to the brain
  - cause headaches, nausea, vomiting, and diarrhea
* cause blood vessels to narrow, impeding the supply of oxygen to the uterus
  - pain and inflammation in damaged tissues - leukotrienes cause asthma
* causes the muscle tissue of the mother to push the fetus out of the uterus
  - mother to push the fetus out of the womb
* contribute to the inflammatory response which produces swelling and pain.
* control an array of vital bodily functions.
* decrease the viscosity of mucus at the cervix.
* differ in type depending on the type of fatty acids available.
* effectively thin the blood.
* establish the inflammatory response.
* have a variety of effects throughout the body
  - very short life-span, which is why the body needs an abundant supply of EFAs
  - several pharmacological effects on the female reproductive system
* help relieve the inflammation of fibromyalgia.
* helps protect the stomach lining from the acidic digestive juices.
* increase matrix metalloproteinase release from human ciliarysmooth muscle cells
  - oxygen uptake and most likely participate in a hypermetabolic state
* induces labor, delivering dead baby.
* inhibit mucus formation in the stomach.
* is lipids
  - luteolytic
  - medicine
  - secretion
* keep blood pressure low and influence hormone activity.
* occur naturally in the body and are involved in many biological functions.
* play a vital role in inflammation, tissue repair, and the immune response
  - an important role regulating the renal cortical microcirculation
* regulate the female reproductive cycle by causing luteolysis
  - synthesis and secretion of the atrial natriuretic peptide
* regulates blood pressure and water-salt balance.
* sensitize tissue to pain.
* stimulate renin secretion and renin mrna in mouse renal juxtaglomerular cells.
* suppress an outward potassium current in embryonic rat sensory neurons.
* work much like hormones do to help the body's cells maintain normal functioning.
* works by decreasing the levels of progesterone, the hormone that maintains pregnancy.
