1. Which of the following is not a function of the circulatory system?
breaks down large molecules
delivers oxygen to body cells ****
takes carbon dioxide away from body cells
fights infection
2. Which of the following explains why the heart is organized so that it pumps
blood to two different locations?
to supply blood to two different sides of the body
to allow a way for the blood to pick up new blood cells
to move oxygen-poor blood through the lungs and to move oxygen-rich blood
to the rest of the body
to provide a way for blood to pick up nutrients at one location and oxygen at another ****
3. Which set of terms below would be the best choice to use to describe
the components of blood?
leukocytes, ventricle, atrium, aorta
platelets, plasma, erythrocytes, leukocytes ****
electrolytes, artery, vein, cardiac
antibodies, hemoglobin, pulmonary, systemic
1. A.
2. C.
3. B.
4. C.
#1 incorrect.
Question asks which function is not one of the circulatory system.
#2. incorrect.
Blood has the dual function of supplying oxygen to different parts of the body and also to exchange excreted carbon dioxide with oxygen of fresh air.
#3. correct.
Takes carbon dioxide from the body cells

To answer these questions, we need to understand the functions of the circulatory system, the organization of the heart, and the components of blood. Here's how we can get the answers:
1. To determine which of the following is not a function of the circulatory system, we need to know what the circulatory system does. We can find this information in biology textbooks or reputable online resources. One way to search for this information is to use keywords such as "functions of the circulatory system." By reading the information provided, we can identify that the circulatory system delivers oxygen to body cells and takes carbon dioxide away from body cells. Therefore, the answer is "delivers oxygen to body cells."
2. To understand why the heart is organized to pump blood to two different locations, we need to know its purpose and structure. We can search for information on the heart's organization and function using keywords such as "function of the heart" or "heart structure." By reading reliable sources, we can learn that the heart pumps oxygen-poor blood through the lungs and oxygen-rich blood to the rest of the body. This allows blood to pick up nutrients at one location (digestive system) and oxygen at another (respiratory system). Therefore, the answer is "to provide a way for blood to pick up nutrients at one location and oxygen at another."
3. To describe the components of blood, we need to know the different elements present in blood. To find this information, we can search for keywords like "components of blood" or "blood composition." By referring to credible sources, we can learn that blood consists of platelets, plasma, erythrocytes (red blood cells), and leukocytes (white blood cells). Therefore, the best choice to describe the components of blood is "platelets, plasma, erythrocytes, leukocytes."
By following these research steps, we can find the correct answers to the questions.
