Transportation and communication are compared
to veins and arteries of our
body. Explain.

The means of transportation and communication are called the lifelines of a nation and its economy because they are the pre-requisites for the development of a country. ... This facilitates transportation of goods and services from production units to the demand locales.

Located throughout the body, arteries transport nutrient-rich, oxygenated blood to organs and tissues. Arteries are more muscular and have smaller, rounder lumens (internal spaces) than veins. The artery lumen has a wavy endothelium, or inner lining, due to the configuration of elastic tissue beneath it.

concurrent jurisdiction is the ability to exercise judicial review by different courts at the same time, within the same territory, and over the same subject matter. for instance, a domestic violence matter may be heard in either a general civil court or a family court in the same county. whichever court actually exercises its jurisdiction first will do so exclusively.
