Which of the following is an example of an organ system?
a human bladder storing waste for removal from the body
B.
a plant's roots absorbing water and minerals from soil
C.
the living material that lines the inside of a cheek
D.
a heart, arteries, and veins all working together
D. a heart, arteries, and veins all working together
D. a heart, arteries, and veins all working together
The correct answer is D. A heart, arteries, and veins working together is an example of an organ system.
To get to this answer, you can eliminate options A, B, and C by identifying them as individual organs or tissues, rather than a system. Option A is a specific organ, the human bladder, which is responsible for storing waste for removal from the body. Option B is another specific organ, the roots of a plant, which absorb water and minerals from the soil. Option C refers to the living material that lines the inside of a cheek, which is an example of tissue.
Option D, on the other hand, is the combination of the heart, arteries, and veins, all working together. This arrangement forms the cardiovascular system, which transports blood throughout the body. Therefore, option D is the example of an organ system in this set of choices.
