Essays on Tissues And Organs

<<Author>> <<Date>> According to Xu et al. (2012), multiple tissues and organs in our body have this signaling system with AMPK and the balance in energy is accomplished by these sensors. The regulation done by this pathway is very important and any deficiency can lead to disorders like type 2 diabetes, obesity and other syndromes. Whenever nutrient insufficiency occurs the activation of AMPK takes place; which signals feeding. These are controlled in the hypothalamus region with the use of glucose, leptin and insulin (Akabas et al., 2012). AMPK and mTOR play a very ...

The respiratory system of humans comprises of a complex set of tissues and organs, which gets oxygen from the surrounding and carry it to the lungs. The basic role of the respiratory system is to provide the blood with oxygen so that the blood can convey oxygen to every body part. The respiratory system achieves this through inhalation and exhalation. When one breathes, oxygen is inhaled while carbon dioxide is exhaled. This gaseous exchange is the means of the respiratory system to get oxygen to the blood. The tissues and organs, which constitute the respiratory system of humans, are the ...

Introduction

Scientists have discovered a way of turning off genes so as to provide room for studying how cells work and other aspects of the cells. The discovery has been deemed to be a major success towards a news technology in studying the biochemical pathways and interactions that occur in cells hence facilitating normal development as well as disease progression. Norris (Para. 1) points out that, scientists at UC San Francisco have made this major breakthrough of turning off genes in cells. They indicate that the ability to turn off genes will pave way to increase in research and making of discoveries in ...
