Name: ___________ Science Chapter 4 Body Systems Study Guide 1. What part of the digestive system absorbs some water from waste? Large Intestine 2. Where does food enter the blood vessels? Villi 3. When your diaphragm contracts what is happening? You are inhaling air 4. The esophagus connects what two structures? The mouth to the stomach 5. What body system contains the heart, blood, and blood vessels? Circulatory System 6. What are the smallest blood vessels in the body? Capillaries 7. Where does the digestion of food begin? Mouth 8. Whose job is it to remove waste from the blood? Kidneys 9. What gas passes from the blood into the body’s cells? Oxygen 10. Where does oxygen enter the bloodstream? Air sacs 11. How do the digestive and circulatory system work together to get food to your body’s cells? The digestive system breaks food down into a form that the body’s cells can use. The circulatory system carries the food to each cell in the body. 12. Explain the role of the respiratory system in the human body. Why is this system important? The respiratory system’s role is to bring oxygen into the body and move carbon dioxide out. This system is important because body cells need oxygen to get energy from food, and for removing carbon dioxide made by cells. 13. Compare the blood in the arteries going out to body cells with the blood in veins coming back to the heart from body cells. The blood in arteries has more oxygen and food for cells. The blood in veins has more carbon dioxide and wastes from cells. Other things to know: - The order in which blood flows through the heart. Including the arteries and aorta. Right Atrium, Right Ventricle, Artery, Lungs, Left Atrium, Left Ventricle, Aorta (out to the body, then circulates back) - Study the diagram of all the body systems. Know the parts and where they are located. Your notes will help you best for this.
