- Q1When can you “see” or notice your immune system at work?When you get a mosquito biteWhen you have the flu or a coldWhen you have an allergic reactionAll of the above120s
- Q2Which of the following is true of the digestive system?It includes the mouth, lungs, esophagus, and stomachIt gives our bodies a place to exchange carbon dioxide and oxygenIt is responsible for physically and chemically breaking food into usable partsIt relies only on the action of chemicals in the small intestine to get nutrients120s
- Q3The correct level of organization found in humans is…Skin, muscles and bone are the basic building unitsOrgans form tissues which form cells which form organellesAll of the above depending on the age of the personCells form tissues which form organs which form organ systems120s
- Q4In the human respiratory system, there are structures called cilia. Why are these important?They warm and moisten the air we breatheThey trap and filter dust and debrisThey are the place of gas exchange in our lungsThey are the branches of the bronchial tree120s
- Q5When air moves into your respiratory system, what pathway is followed?Mouth and nose -> Pharynx -> Trachea -> Right and left bronchi -> Bronchi -> Bronchioles -> AlveoliDiaphragm -> Trachea -> Lungs -> Alveoli -> Bronchus -> Cilia -> Small intestine -> AnusMouth and nose -> Cilia -> Bronchioles -> Alveoli -> Bronchial treeMouth -> Pharynx -> Esophagus -> Stomach -> Small intestine -> Liver -> Large intestine -> Anus120s
- Q6Which of the following is NOT true of cellular respiration?It produces carbon dioxide and energy as a productIt converts nutrient energy into usable energyIt requires carbon dioxide to occurIt can be either aerobic or anaerobic120s
- Q7Which of the following are examples of accessory organs?The pancreas and liverThe T-cells and B-cellsAll of the aboveThe mouth and stomach120s
- Q8Once absorption of nutrients occurs through the villi in the small intestine, what happens to them?The cilia trap them and move them where they need to goThe nucleus of a cell converts them to tissuesThe bloodstream transports them to cells for cellular respirationThe body excretes them120s
- Q9Where in the respiratory system does the exchange of oxygen and carbon dioxide take place?It happens at the alveoli that are surrounded by blood vesselsIt first occurs in the trachea which is the main air tubeThe cilia are responsible for this function as well as exhalationIt occurs throughout the bronchial tree in the lungs120s
- Q10During a viral infection, which of the following occurs?The natural killer cells destroy infected cells and non-infected cellsA fever might develop to help slow down the reproduction of the virusThe T-cells and B-cells are called into action and antibodies are producedAll of the above120s
- Q11What happens during inhalation?The muscles in the bronchial tree relax and air pressure in the lungs increases as the chest cavity gets smaller.The diaphragm contracts which increases the size of the chest cavity. This lowers the pressure inside the lungs so air rushes in.The esophagus and the pharynx work together to move air into the bronchial tree.The trachea contracts and relaxes in rhythmic waves to pull air into the chest cavity.120s
- Q12Which of the following is NOT true of the small intestine?It contains structures called villi to increase its surface areaIt is where most nutrients are absorbedIt is where the feces are formed and storedIt is longer in length than the large intestine120s
- Q13The wavelike contractions of smooth muscle that move food down the esophagus are called...DigestionAbsorptionPeristalsisExcretion120s
- Q14Your body needs vitamins because ...they provide the building material of musclethey help carry out chemical reactionsthey are a main energy sourcethey insulate the body’s organs120s
- Q15Where does digestion begin?In the mouthIn the small intestineIn the liverIn the stomach120s
