The Body's Transport System
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

^^ This is correct i just took this test
m is right ty
She is right, thanks!
thank you i just took the quick check and got 4/4 100%
cool so im assuming that some of you are from connections as well?
I FROM CONNEXUS
me too
1) To determine the correct answer, you need to understand the function of the circulatory system. The circulatory system is responsible for delivering oxygen to body cells, removing carbon dioxide from body cells, and fighting infection. It does not have a function to break down large molecules. Therefore, the correct answer is "Breaks down large molecules."
2) To understand why the heart is organized to pump blood to two different locations, you need to know the purpose of the circulatory system. The circulatory system is responsible for transporting oxygen-rich blood from the lungs to the rest of the body and oxygen-poor blood from the body back to the lungs. The heart is organized in a way that allows it to pump oxygen-poor blood to the lungs and oxygen-rich blood to the rest of the body. Therefore, the correct answer is "To move oxygen-poor blood through the lungs and to move oxygen-rich blood to the rest of the body."
3) To describe the components of blood, you need to know the different parts of blood. Blood is composed of plasma, platelets, erythrocytes (red blood cells), and leukocytes (white blood cells). Among the given options, the set of terms that includes these components is "Platelets, plasma, erythrocytes, leukocytes." Therefore, the correct answer is "Platelets, plasma, erythrocytes, leukocytes."
4) To determine the correct path of blood through the circulatory system, you need to understand the flow of blood. The heart pumps blood out through arteries, which carry oxygenated blood to the body. The oxygen is then used by the body's cells, and deoxygenated blood returns to the heart through veins. The deoxygenated blood is then pumped to the lungs where it absorbs oxygen again. Among the given options, the correct path is "Heart>arteries>lungs(capillaries)>veins>heart." Therefore, the correct answer is "Heart>arteries>lungs(capillaries)>veins>heart."
