(answered) – 1 of 25 Which of the following describes structures from theDescriptionSolution downloadThe Question?1 ?of?25Which of the following describes structures from the conduction zone?Pharynx, alveolar sacs, alveoli, tracheaBronchus, nasal cavity, trachea, pharynxNasal cavity, respiratory membrane, alveoli, bronchusTrachea, bronchus, bronchioles, alveoliPharynx, larynx, bronchus, alveoliQuestion 2 ?of?25What structure in the nasal cavity serves to increase the surface area of the mucosa exposed to air?PalateConchaeNasal septumNaresParanasal sinusesQuestion 3 ?of?25What is internal respiration?The intake of atmospheric air into the bodyGas exchange between the atmospheric air and the bloodGas exchange between the lungs and the body tissuesGas exchange between the blood and the tissue cellsIntake of oxygen and release of carbon dioxide from tissue cellsQuestion 4 ?of?25What is the role of the diaphragm in breathing?When the diaphragm contracts, the thoracic cavity decreases in size and inspiration occurs.When the diaphragm contracts, the thoracic cavity increases in size and expiration occurs.When the diaphragm contracts, the thoracic cavity decreases in size and expiration occurs.When the diaphragm contracts, the thoracic cavity decreases in size and external respiration occurs.When the diaphragm contracts, the thoracic cavity increases in size and inspiration occurs.Question 5 ?of?25What determines the flow of gases across the respiratory membrane?Gases are dissolved in the plasma and flow through the respiratory membrane gaps.Gases flow from lower to higher concentration using simple diffusion.Gases flow from a higher to lower concentration using simple diffusion.Gases attach to a hemoglobin molecule and then travel across the membrane.Gases are dissolved in the plasma and cross using facilitated diffusion.Question 6 ?of?25Which of the following describes the movement of carbon dioxide?Carbon dioxide moves from alveolar air into pulmonary capillaries.Carbon dioxide moves from pulmonary capillaries into alveolar air.Carbon dioxide moves from blood to tissue cells.Carbon dioxide binds to hemoglobin and is removed through the kidneys.Carbon dioxide moves from blood to oxyhemoglobin.Question 7 ?of?25What is the significant function of the residual volume?It expands the lung volume.It increases the surfactant of the alveoli.It allows gas exchange to continue even between breaths.It represents the total lung capacity of a body.It keeps the oxygen levels as low as possible.Question 8 ?of?25What area(s) of the brain are involved in the control of breathing?Medulla onlyCerebellum onlyPons onlyMedulla and the cerebellumMedulla and the ponsQuestion 9 ?of?25What is an important chemical stimulus that affects breathing rate?Increased calcium levelsIncreased anxietyIncreased carbon dioxide levelsIncreased potassium levelsIncreased mucous production in the bronchusQuestion 10 ?of?25What is the proposed reason for sudden infant death syndrome (SIDS)?Decreased oxygen flow across the respiratory membraneImpaired neural control of respirationIncreased build-up of carbon dioxideImpaired respiratory membranesDecreased alveolar elasticityQuestion 11 ?of?25Which of the following is associated with COPD?Lack of mucous production resulting in excessive coughingCessation of breathing due to anxietyHyperventilation resulting in metabolic alkalosisA genetic disorder with excessive mucous productionRespiratory failure and respiratory acidosisQuestion 12 ?of?25In which major digestive organ does most food absorption occur?StomachSmall intestineLarge intestineLiverColonQuestion 13 ?of?25What layer of the alimentary canal contains nerve fibers and lymphatic tissue?MucosaSubmucosaMusc
