Question

read the passage and look at the graphic. then answer the question. the human heart the heart is one of the most important muscles in the body. it beats over 115,000 times and pumps about 2,000 gallons of blood every day. the heart is roughly the size of a fist in most adults. exercise and eating right are necessary for keeping the heart healthy. the heart has four chambers, or areas, and the valves act like doors that only allow blood to flow in one direction. blood enters the heart through veins, and it leaves the heart through arteries. chambers of the human heart complete the sentence to tell how the diagram helps you understand the topic. from the diagram, i know what the heart looks like inside how many times the heart beats what organs are next to the heart which parts are veins and arteries

Explanation:

A diagram of the heart's chambers would show its internal structure. The passage mentions the heart's chambers and how blood flows (through veins and arteries). A diagram would visually represent these internal components. The number of heartbeats is a numerical fact from the text (not shown in a diagram of chambers). The organs next to the heart aren't relevant to a diagram of heart chambers. A diagram of chambers would focus on internal parts (like which are veins/arteries within the heart's structure).

Answer:

what the heart looks like inside, which parts are veins and arteries
