Astudent makes the analogy that the cardiovascular system is like a highway. why is this a good analogy? a. blood is made of many different kinds of cells. b. the heart pumps blood through the veins. c. the heart is centralized in the body. d. blood transports materials to and from different parts of the body.

The right answer is D.

Blood is a vital biological fluid that circulates continuously in the blood vessels and heart, especially through the heart pump. It is composed of an aqueous fluid, plasma, and billions of cells, mainly red blood cells, which give it its color.

This fluid transports oxygen (O2) and nutrients necessary for the vital processes of all tissues of the body, as well as wastes, such as carbon dioxide (CO2) or nitrogenous waste, to the evacuation sites (kidneys), lungs, liver, intestines). It also allows the cells and molecules of the immune system to be transported to the tissues, and to spread hormones throughout the body.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
