Fluids, Pressure, and Circulation CHAPTER Fluids, Pressure, and Circulation NEW CHAPTER the BIG idea The body uses fluid pressure in many ways. 11.1 Fluids spread force over an area. 11.2 The heart procedures blood pressure. 11.3 Fluid pressure affects the body in different ways. CHAPTER OUTLINE CHAPTER RESOURCES

Fluids spread force over an area. 11.1 Fluids spread force over an area. CALIFORNIA Content Standards 7.5.b Students know organ systems function because of the contributions of individual organs, tissues, and cells. The failure of any part can affect the entire system. 7.6.j Students know that contractions of the heart generate blood pressure and that heart valves prevent backflow of blood in the circulatory system. fluid pressure CHAPTER RESOURCES SECTION OUTLINE

Fluids spread force over an area. 11.1 Fluids spread force over an area. Fluids push in all directions. Pressure on a fluid can transfer a force to a different location, spread out a force, and cause the fluid to move. fluid pressure CHAPTER RESOURCES SECTION OUTLINE

The heart produces blood pressure. 11.2 The heart produces blood pressure. CALIFORNIA Content Standards 7.5.a Students know plants and animals have levels of organization for structure and function, including cells, tissues, organs, organ systems, and the whole organism. 7.5.b Students know organ systems function because of the contributions of individual organs, tissues, and cells. The failure of any part can affect the entire system. 7.6.j Students know that contractions of the heart generate blood pressure and that heart valves prevent backflow of blood in the circulatory system. circulatory system artery vein capillary CHAPTER RESOURCES SECTION OUTLINE

The heart produces blood pressure. 11.2 The heart produces blood pressure. The heart acts as two pumps that produce pressure. circulatory system Blood flows from the heart through arteries, capillaries, veins, and then back to the heart. The left side pumps blood through the body in the systemic circuit. artery vein capillary The right side pumps blood through the lungs in the pulmonary circuit. CHAPTER RESOURCES SECTION OUTLINE

Fluid pressure affects the body in different ways. 11.3 Fluid pressure affects the body in different ways. CALIFORNIA Content Standards 7.5.g Students know how to relate the structures of the eye and ear to their functions. 7.5.b Students know organ systems function because of the contributions of individual organs, tissues, and cells. The failure of any part can affect the entire system. mucus semicircular canals CHAPTER RESOURCES SECTION OUTLINE

Fluid pressure affects the body in different ways. 11.3 Fluid pressure affects the body in different ways. Fluids serve one or more purposes in all major organ systems. Fluids divert and spread forces, support, transport materials, lubricate, and block materials. mucus semicircular canals The motion of fluids in the ear gives you a sense of balance. tilt nod turn CHAPTER RESOURCES SECTION OUTLINE
