Name:_KEY______________________ Excretory, Circulatory, Respiratory System Review Excretory System What is the function of the excretory system? to get rid of waste and other substances the body doesn’t need Organ What does it excrete? Lungs Carbon dioxide Integumentary System Sweat Digestive System Feces Urinary System Urine Label the parts of the urinary system. KIDNEY URETER BLADDER URETHRA Which urinary organ produces the urine? Kidneys What is the function of the kidney? Filter the blood, produce urine Respiratory System What is the function of the respiratory system? To supply the blood with oxygen To excrete Carbon dioxide as waste Label the following (there are extra lines): nose/mouth (1&2)
trachea (3&7&8)
bronchi (5&9)
lungs (4)
diaphragm (6)
bronchioles (10) alveoli (11) What is the pathway that air takes to get into the bloodstream? nose/mouth_­­>_trachea____­­­>_bronchi_­­>_bronchioles__­­>_alveoli____ Which major organ is responsible for gas exchange? lungs (specifically alveoli) Why does our body need oxygen? Oxygen allows our cells to convert nutrients to energy Which organ’s movement allows you to breathe? diaphragm regulates breathing Which part of the respiratory system exchanges gas through the capillaries? alveoli What is the waste product of the respiratory system? Carbon dioxide Circulatory System What is the function of the circulatory system? distributes oxygen and nutrients to all body parts removes waste from body parts What is the difference between arteries and veins? arteries carry blood away from the heart veins carry blood toward the heart What do capillaries do that other blood vessels do not? capillaries allow substances (like gases and nutrients) to pass through their walls (because they are so thin) What is the purpose of red blood cells? carry oxygen to all parts of the body What is the purpose of white blood cells? fight germs/disease What causes the speed of your heart beat to change? Exercise! ­ muscles require more oxygen so the heart beats faster to make sure they get enough oxygen Which two systems work together to….. remove waste products from the blood? excretory/circulatory distribute oxygen to all parts of the body? respiratory/circulatory distribute nutrients to all parts of the body? digestive/circulatory
