A student makes the analogy that the cardiovascular system is like a highway. Why is this a good analogy? Blood is made of many different kinds of cells. The heart pumps blood through the veins. The heart is centralized in the body. Blood transports materials to and from different parts of the body.

Explanation:

cardiovascular system is the circulatory system, it permits the circulation of blood and allows for transport of nutrients such as amino acids and electrolytes, oxygen and carbon dioxide gases, hormones, and blood cells in the body. It also helps the body to provide nourishment and fight against diseases and maintain homeostasis.

It is consider an high way because of its function. An high way allows for free passage, with often time no obstruction this is what cardiovascular system does they allow for movement of blood and essential nutrient in the body system for effective function of our body.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
