2 1 What is the shortest and thinnest blood vessel? rtery apillary Vein lveoli 2 The role of hemoglobin in blood is to. carry oxygen stop cuts from bleeding make white blood cells kill bacteria and other harmful things in blood 3 What do platelets do? Platelets carry gases between the lungs and body cells. Platelets make red blood cells and plasma. Platelets help the blood to clot. Platelets help the body fight germs. 4 People who have sickle cell anemia have misshapen red blood cells. What causes this disease? acteria cause sickle cell anemia.

4 Use the illustration to answer Questions 7 and 8. The eart Left atrium Right atrium Left ventricle Right ventricle 7 The blood that fills the right atrium and right ventricle has than the blood that fills the left atrium and left ventricles. more oxygen less oxygen more red blood cells fewer white blood cells and platelets Macmillan/Mcraw-ill TKS Science rade 5, hapter 13 4

5 8 valve separates the right atrium from the right ventricle. What does the valve do? The valve lets blood move only from the atrium to the ventricle. The valve lets blood move only from the ventricle to the atrium. The valve lets blood move in either direction between atrium and ventricle. The valve lets red blood cells pass through, but not white blood cells 9 The is a stiff, wide tube that carries air between the throat and lungs. aorta trachea alveoli bronchiole 10 ow does a muscle called the diaphragm affect breathing? The diaphragm opens and closes the opening of the esophagus, which leads to the stomach. The diaphragm pulls on the trachea, making it larger or smaller. The diaphragm removes oxygen from the air as the air rushes by it. ir rushes in and out of the lungs as the diaphragm changes the size of the chest cavity.

6 11 People take in oxygen from the air as they breathe. Why does the air s oxygen supply not run out? Water adds oxygen to the air as it evaporates from the oceans. Many animals, including birds and reptiles, add oxygen to the air as they breathe. Plants add oxygen to the air as they perform photosynthesis.
