Eicosanoids and Prostaglandins
SAMPLE QUESTIONS 1
Question1 Eicosanoids and Role of Prostaglandins
Eicosanoidsare valuable compounds that result from the from Arachidonic acid. Itis specifically omega six fatty acid that is polyunsaturated. Thecompound is obtained from eating mostly animal fats. The fatty acid-derived compound plays vital roles in the body. One of the functionsis influence on the immune response, reproductive, and respiratorysystem. Secondly, it acts as blood pressure regulator (Nussey& Whitehead, 2013).Thirdly, it plays a useful role in the inflammation process. Lastly,it promotes blood clotting.
Prostaglandinsperform different body functions by creating opposite effects to thetarget cells. It is a type of eicosanoid that is responsible fordilation or constriction of blood vessels, inducing a change in bloodpressure. Secondly, prostaglandins regulate inflammatory responsethereby initiating the healing process. The compound also helps indilation or constriction of the lungs and the alveolar spaces so thatefficient breathing is realized. Also, prostaglandins also initiatepain and induce fever. Lastly, the compound is useful in obstetricssince it helps in contraction of the smooth muscles especially thoseof the uterus during labor. Therefore, the product is helpful ininitiating the efficient delivery process (Nussey& Whitehead, 2013).
Question2. Benefits of Exercise for the Heart
Oneshould make develop a habit of exercising quite often. Exercise holdsa focal point when it comes to maintaining the integrity of the heartsmooth muscles, and the overall functioning of the heart. A goodphysical exercise hardens the smooth muscle walls, making them stiffenough therefore do not succumb to most of the heart complications.Exercise increases the blood flow from the heart to other parts ofthe body. Therefore, chances of cardiovascular disorders and bloodpressure are significantly minimized. Exercise also helps inreduction of bad low-density lipoproteins and increases the goodcholesterol thereby reducing chances of atherosclerosis (Vina,Sanchis,Martinez& Gomez,2012).Lastly, exercise increases the insulin sensitivity by activating thereceptors at the specific target cells. This, in turn, is beneficialin checking the acute and onset diabetes mellitus.
