1 NEW CHAPTER Absorption, Digestion, and Exchange CHAPTER the BIG idea CHAPTER OUTLINE Systems in the body obtain and process materials and remove waste. The respiratory system gets oxygen and removes carbon dioxide. The digestive system breaks down food. The urinary system removes waste materials CHAPTER RESOURCES

2 VOCABULARY KEY CONCEPT CHAPTER HOME The respiratory system gets oxygen and removes carbon dioxide. SECTION OUTLINE SECTION OUTLINE cellular respiration respiratory system Your body needs oxygen Structures in the respiratory system function together Your respiratory system is involved in other functions trachea bronchial tube lung diaphragm 2.1 CHAPTER RESOURCES CHAPTER RESOURCES VISUALIZATION Observe how movements of the diaphragm and other muscles affect the lungs.

3 VOCABULARY KEY CONCEPT CHAPTER HOME respiratory system KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The respiratory system gets oxygen and removes carbon dioxide. A system that interacts with the environment and with other body systems to bring oxygen to the body and remove carbon dioxide. cellular respiration respiratory system 2.1 CHAPTER RESOURCES CHAPTER RESOURCES

4 VOCABULARY KEY CONCEPT CHAPTER HOME A process in which cells use oxygen to release energy stored in sugars. cellular respiration KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The respiratory system gets oxygen and removes carbon dioxide. cellular respiration respiratory system 2.1 CHAPTER RESOURCES CHAPTER RESOURCES

5 VOCABULARY KEY CONCEPT CHAPTER HOME nutrient The digestive system breaks down food. SECTION OUTLINE SECTION OUTLINE digestive system peristalsis digestion FunctionStructure Mouth Esophagus Stomach Small intestine Large intestine chemical and mechanical digestion movement of food by peristalsis from mouth to stomach chemical and mechanical digestion; absorption of broken-down nutrients chemical digestion; absorption of broken-down nutrients absorption of water and broken-down nutrients, elimination of wastes mouth esophagus stomach small intestine large intestine 2.2 CHAPTER RESOURCES CHAPTER RESOURCES

6 VOCABULARY KEY CONCEPT CHAPTER HOME nutrient The digestive system breaks down food. SECTION OUTLINE SECTION OUTLINE digestive system peristalsis digestion FunctionStructure Mouth Esophagus Stomach Small intestine Large intestine chemical and mechanical digestion movement of food by peristalsis from mouth to stomach chemical and mechanical digestion; absorption of broken-down nutrients chemical digestion; absorption of broken-down nutrients absorption of water and broken-down nutrients, elimination of wastes mouth esophagus stomach 2.2 small intestine CLASSZONE.COM VISUALIZATION Observe the process of peristalsis. CHAPTER RESOURCES CHAPTER RESOURCES

7 VOCABULARY KEY CONCEPT CHAPTER HOME A substance that an organism needs to live. Examples include water, minerals, and materials that come from the breakdown of food particles. nutrient KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The digestive system breaks down food. nutrient digestive system peristalsis digestion 2.2 CHAPTER RESOURCES CHAPTER RESOURCES

8 VOCABULARY KEY CONCEPT CHAPTER HOME The process of breaking down food into usable materials. digestion KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The digestive system breaks down food. nutrient digestive system peristalsis digestion 2.2 CHAPTER RESOURCES CHAPTER RESOURCES

9 VOCABULARY KEY CONCEPT CHAPTER HOME The structures in the body that work together to transform the energy and materials in food into forms the body can use. digestive system KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The digestive system breaks down food. nutrient digestive system peristalsis digestion 2.2 CHAPTER RESOURCES CHAPTER RESOURCES

10 VOCABULARY KEY CONCEPT CHAPTER HOME Wavelike contractions of smooth muscles in the organs of the digestive tract. The contractions move food through the digestive system. peristalsis KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The digestive system breaks down food. nutrient digestive system peristalsis digestion 2.2 CHAPTER RESOURCES CHAPTER RESOURCES

11 VOCABULARY KEY CONCEPT CHAPTER HOME The urinary system removes waste materials. SECTION OUTLINE SECTION OUTLINE urinary system urine Waste Removal Respiratory System removes carbon dioxide Urinary System removes wastes from body Digestive system removes wastes from food Skin removes water KidneysUrine Kidneys 2.3 CHAPTER RESOURCES CHAPTER RESOURCES

12 VOCABULARY KEY CONCEPT CHAPTER HOME A group of organs that filter waste from an organisms blood and excrete it in a liquid called urine. urinary system KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The urinary system removes waste materials. urinary system urine 2.3 CHAPTER RESOURCES CHAPTER RESOURCES

13 VOCABULARY KEY CONCEPT CHAPTER HOME Liquid waste that is secreted by the kidneys. urine KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The urinary system removes waste materials. urinary system urine 2.3 CHAPTER RESOURCES CHAPTER RESOURCES

14 VOCABULARY KEY CONCEPT CHAPTER HOME I. The respiratory system gets oxygen and removes carbon dioxide. A. Your body needs oxygen. C. The respiratory system is also involved in other activities. KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The respiratory system gets oxygen and removes carbon dioxide. 1. Exchanging Oxygen and Carbon Dioxide 2. Cellular Respiration B. Structures in the respiratory system function together. 1. Speech and Other Respiratory Movements 2. Water Removal cellular respiration respiratory system 2.1 CHAPTER RESOURCES CHAPTER RESOURCES

15 VOCABULARY KEY CONCEPT CHAPTER HOME KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The digestive system breaks down food. II. The digestive system breaks down food. A. The body needs energy and materials. B. The digestive system moves and breaks down food. 1. Mechanical Digestion 2. Chemical Digestion C. Materials are broken down as they move through the digestive tract. nutrient digestive system peristalsis digestion D. Other organs aid digestion and absorption. 2.2 CHAPTER RESOURCES CHAPTER RESOURCES

16 VOCABULARY KEY CONCEPT CHAPTER HOME III. The urinary system removes waste materials. A. Life processes produce waste. 1. The Nephron 2. Water Balance B. The urinary system removes waste from the blood. KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The urinary system removes waste materials. C. The kidneys act as filters. urinary system urine 2.3 CHAPTER RESOURCES CHAPTER RESOURCES
