The cardiovascular system transports and nutrients to the cells of all the organs.

*blood vessels also transport from the cells which is later by the urinary system.

*contractions of the keep blood moving while the protects the heart and produces red blood cells.

*the cardiovascular system transports the produced by the endocrine system, moving them from to their target organs.

*interactions between the cardiovascular system and other body systems the body maintain its internal , or homeostasis.

*The cardiovascular system transports oxygen and nutrients to the cells of all the organs.

Molecules  transported by cardiovascular system are nutrients such as amino acids and electrolytes, CO2, oxygen, hormones and all necessary components for the properly working of the cell (nourishment, fighting diseases, stabilizing temperature and pH, and maintaining homeostasis).

*Blood vessels also transport waste from the cells which is later excreted by the urinary system.

Waste taken from the cells to the blood is then filtered out from the blood as it flows through the kidneys. That waste leaves the body in the form of urine.

*Contractions of the muscular system keep blood moving while the skeletal system protects the heart and produces red blood cells.

Smooth muscles surround blood vessels of the circulatory system and are responsible for the constriction and dilatation of them. The cardiac skeleton is located around heart and has protective function. Red blood cells are produced by bone marrow which is located within the bones.

*The cardiovascular system transports the hormone produced by the endocrine system, moving them from glands to their target organs.

Endocrine glands produce hormones and release them into the blood and that is what distinct them from exocrine glands.

*Interactions between the cardiovascular system and all other body systems help the body maintain its internal balance, or homeostasis.

All systems work together to resist changes and to maintain a stable, relatively constant organism.

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.
