ANS: Structure C is the valve that separates the left atrium from the left ventricle. Its function is to prevent blood from flowing backward from the ventricle into the atrium.

OBJ: CaLS.14.1.2 Describe the function and structure of the heart. STA: S 7.6.j BLM: application 65. ANS: D is the left ventricle. Blood entering the left ventricle is high in oxygen, because it has just come from the left atrium, which receives oxygen-rich blood from the lungs. OBJ: CaLS.14.1.2 Describe the function and structure of the heart. CaLS.14.1.3 Sequence the path taken by blood through the cardiovascular system. STA: S 7.6.j BLM: application 66. ANS: Structure E is the septum. A hole in the septum would allow oxygen-poor blood to mix with oxygen-rich blood. As a result, less oxygen would go to body cells. PTS: 1 DIF: L3 OBJ: CaLS.14.1.2 Describe the function and structure of the heart. STA: S 7.5.b BLM: synthesis 67. ANS: A is a red blood cell. OBJ: CaLS.14.2.1 Describe the components of blood.

ANS: Cells produce carbon dioxide as a waste product. The carbon dioxide passes from the cells into the blood. The cardiovascular system carries the carbon dioxide to the lungs. The carbon dioxide is exhaled. OBJ: CaLS.14.1.1 Explain the functions of the cardiovascular system. 74. ANS: The overall pattern of blood flow through the body is somewhat like a figure eight with the heart at the center where the two loops cross. In the first loop, blood travels from the heart to the lungs and then back to the heart. In the second loop, blood is pumped from the heart throughout the body and then returns to the heart. OBJ: CaLS.14.1.3 Sequence the path taken by blood through the cardiovascular system. STA: S 7.6.j BLM: comprehension 75. ANS: When the artery muscles contract, the opening in the artery becomes smaller. Less blood flows through them. When the artery muscles relax, the opening becomes larger. More blood flows through them. OBJ: CaLS.14.1.4 Describe the functions and structures of arteries, capillaries, and veins. STA: S 7.6.j BLM: comprehension 76. ANS: Some blood types react to certain marker molecules by clumping. People with type AB blood do not produce clumping chemicals that act against either A or B markers. Type O blood does not contain either A or B markers. Therefore, a person with group AB blood can accept a transfusion of any blood type, because no clumping will occur. OBJ: CaLS.14.2.2 Explain what determines the type of blood that a person can receive in a transfusion. STA: S 7.5.b BLM: comprehension

77. ANS: Before it entered the lymphatic system, the lymph was part of the blood. It then leaks out of blood vessels and bathes body tissues. The lymphatic system returns lymph to the bloodstream by emptying it into large veins in the chest. OBJ: CaLS.14.2.3 Name the structures and functions of the lymphatic system. 78. ANS: Breathing is the movement of air into and out of the lungs. Respiration, which is also called cellular respiration, is the process in which oxygen and glucose chemically react to release energy from glucose. OBJ: CaLS.14.3.1 Describe the functions of the respiratory system. STA: S 7.5.a BLM: analysis 79. ANS: Iron is needed for the production of the protein hemoglobin, which binds to oxygen so blood can transport the oxygen throughout the body. A person with anemia would not have enough iron to create needed hemoglobin. Without enough hemoglobin, the red blood cells would be unable to carry oxygen efficiently. Enough oxygen might not reach all the organs of the body. The lungs would have to work harder, and the anemic person would feel tired and short of breath. PTS: 1 DIF: L3 OBJ: CaLS.14.2.1 Describe the components of blood. STA: S 7.5.b BLM: synthesis 80. ANS: Bronchitis is a narrowing of small air passages. Bronchitis makes breathing difficult and is often accompanied by infections of the respiratory system. Eventually, bronchitis may permanently damage the breathing passages. OBJ: CaLS.14.4.3 Identify respiratory diseases that result from infections or other physical conditions. STA: S 7.5.b BLM: comprehension
