They examine how the muscle of the smooth intestine propels food through the digestive tract and describe the process by which nutrients are broken down and absorbed. Both anatomists and physiologists know that form and function of the small intestine are interrelated. 5. When you study with a partner, you each can help the other identify gaps in your knowledge, keep study sessions focused and on track, and serve as a sounding board when explaining a concept. 6. The ability of organisms to respond to stimuli such as changes in either their external or internal environment provides them with a mechanism for maintaining a constant internal environment, even as the environment around them changes. 7. A higher level of organization does contain all of the levels beneath it. Each level of organization is a function of the arrangement of its subsequent subunits, which in turn are a function of the organization of their subunits. Therefore, each level of organization is dependent on the organization of all of the levels below. 8. The urinary system is responsible for filtering and removing waste products from the blood. 9.
