Which of the following statements is FALSE?Question 22Answera.During exhalation, air exits the lungs by moving against it's pressure gradientb.The contraction of the diaphragm and external intercostal muscles is the first step of inhalationc.During forced breathing, both inhalation and exhalation are active processes that make use of muscle contractionsd.During inhalation, air enters the lungs by moving down its pressure gradiente.According to Boyle's law, pressure and volume are inversely related

Which of the following statement(s) is(are) true regarding exhalation? Question 26 options: there is a decrease in both the lung volume and pressure in the lungs there is a increase in the lung volume and diaphragm moves downward there is a decrease in lung volume and the diaphragm moves downward there is a decrease in lung volume and the diaphragm moves upward there is a increase in the lung volume and the diaphragm moves upward

Which of the following events does not occur during exhalation in human beings?The inter-costal muscles pull the ribs inwardlyThe volume of thoracic cavity increasesHigh pressure area is created inside the thoracic cavityDiaphragm becomes dome-shaped

Select the statement that is true about respirationDuring inhalation, ribs move inward and diaphragm is raised In the trachea, exchange of gases take placeHaemoglobin has greater affinity for carbon dioxide than oxygenAlveolus is the functional unit of the lung

During inhalation, expansion of the lungs occurs due to the air rushing in from the outside atmosphere Question 4Answer True False

When the diaphragm and external intercostal muscles contract: choose one• none of these conditions would occur• intrapleural pressure decreases• intrapulmonary pressure increasesO expiration occurs• volume of the lungs decreases
