PLS HELP SUPER HARD 100 POINTS Ian dissects a frog in science class and is interested in the heart. He studies a diagram of the human heart to compare them. He finds that a frog’s heart has two atria and a single ventricle. He returns to the human heart diagram and reads that it is considered a double loop system.

In the center of the diagram is a small round object, with a cutaway to see inside. Inside are two main sections separated by a thick line. The section on the left of the diagram is labeled right side of the heart. There are arrows pointing down and curving back up into a dark tube. The section on the right of the diagram is labeled left side of the heart. There are arrows pointing down from a light tube and then back up. On top of the diagram is a looped tube. One end of the tube is darker and labeled arteries. It is connected to the top of the right side of the heart section, and it has arrows pointing upward. At the top of the diagram the tube splits into smaller tubes labeled, capillaries. The smaller tubes join back into a single, lighter tube, which is labeled veins. This portion of the tube is connected to the top of the left side of the heart section. It has one arrow pointing down. At the bottom of the diagram is a second looped tube. One end of the tube, is lighter and labeled arteries. It is connected to the top of right side of the heart section, and it has arrows pointing downward. At the bottom of the diagram the tube splits into smaller tubes labeled, capillaries. The smaller tubes join back into a single, darker tube, which is labeled veins. This portion of the tube is connected to the top of the right side of the heart section. It has arrows pointing upward.

Why is the human heart called a double loop system?
A. There are two sections, or loops, that each have the same job in the circulatory system.
B. One loop passes through the heart on the way to the body, and the other loop passes through the body to the lungs.
C. One loop takes blood with oxygen to the lungs, and the other loop takes blood and wastes to the body.
D. One loop takes blood with wastes to the lungs, and the other loop takes blood with oxygen to the body.
