The bronchioles branch into bronchi. c. Alveolar ducts connect to alveolar sacs. d. Gas exchange between the lungs and blood takes place in the alveolus.Which of the following transport processes move oxygen and carbon dioxide across the alveolar Type I cell? A. Primary active transport OB. Secondary active transport OC. Convection D. Diffusion OE. Facilitated diffusiona. What concept pertains to the movement of particles across the cell membrane? A. Diffusion B. Active transport C. Facilitated diffusion b. Which respiration which happened between the blood and body tissue? A. Internal respiration B. External Respiration C. Both a and b
- Which of the following is NOT a way that carbon dioxide exits the body? * A. carbon dioxide travels down the concentration gradient and is able to diffuse from the tissues directly out of the body through its pores. B. carbon dioxide dissolves directly into the blood plasma to be carried to the lungs where it will be exhaled. C. Carbon dioxide binds with hemoglobin as red blood cell pass through tissues and is released as the blood cells reached the lungs. D. carbon dioxide converts into bicarbonate ions in the blood as it diffuses from the tissues and converts back to carbon dioxide as it reaches the lungs to be exhaled PLS ANSWWER ASP THANK YOUU SO MUCHThe direction that a gas diffuses is determined by a. the solubility of the gas in the solutions present on either side of a semipermeable membrane b. the partial pressure of the gas on either side of a semipermeable membrane c. the concentration of solutes in the solution into which the gas is dissolving d. none of the choices is correctOxygen and carbon dioxide diffuse across our respiratory surface into and out of the blood via simple diffusion. The respiratory membrane is thin so gases diffuse only a short distance through the liquid and into the blood. Fluid buildup in the lungs increases the distance through the liquid medium. How does this impact the concentration of oxygen in the blood? Explain.
- The process of intake of oxygen and release of carbon dioxide is classified as? * a. Cellular Exchange b. Respiratory Exchange c. Osmosis d. Gaseous Exchange pls answer asap thankyouOxygen diffuses from the inhaled air in the alveoli of the lungs, where its concentration is higher, into the cytoplasm of red blood cells, where its concentration is lower. Patients diagnosed with emphysema have damaged alveoli. This results to fewer, larger air spaces instead of many small ones. Explain how this damage can lead to shortness of breath? The surface area of lungs is reduced. Hence, less oxygen can diffuse into the red blood cells. The surface area of lungs is increased. Hence, more oxygen can diffuse into the red blood B cells. The surface area of lungs is reduced. Hence, more oxygen can diffuse into the red blood cells. The surface area of lungs is increased. Hence, less oxygen can diffuse into the red blood cells.If there were little to no Chloride in the blood, what would happen to CO2 transport and why? Select one: O a. CO2 transport would not change because chloride is not part of the carbonic anhydrase reaction O b. CO2 transport would decline because H+ would not be able to bind to hemoglobin O c. CO2 transport would decline because HCO3 wouldn't be able to exit the red blood cell thus inhibiting the carbonic anhydrase reaction O d. CO2 transport would increase because HCO3 would be able to exit the red blood cell more freely
- The time it takes for blood to pass through the capillaries of a pulmonary alveolus typically is less than 0.3 seconds. During this time, what will occur? Select one: a. The blood plasma will be cleansed of its entire CO2 content and will be saturated with O2. b. An enzyme will catalyze the conversion of oxyhemoglobin to carboaminohemoglobin. c. Blood will pick up CO2 and O2 will be released to the alveolus. d. Blood will pick up O2 and CO2 will be released to the alveolus.I think this is C or D tell me the answer and whyWhich one of the following statements about the afferent components of the respiratory control system is INCORRECT? Select one: a. In order to stimulate hyperventilation the sympathetic nervous system tricks the carotid body by constricting the capillaries that serve glomus cells; reduced blood flow to the cell causes localised hypoxia triggering a compensatory hyperventilation response even before systemic hypoxia is apparent. b. In type 1 glomus cells of the carotid bodies, hypoxia, hypercapnia and acidosis trigger afferent signalling by inhibiting K+ channels, depolarising the cell membrane, and opening voltage-gated Ca2+ channels that trigger the release of neurotransmitters onto afferent glossopharyngeal nerve fibres. c. Chemoreceptor cells can be found in the carotid body. d. The glossopharyngeal nerve transmits afferent impulses from the carotid body to the ventral respiratory group of neurons.A type II alveolar cell in the lungs is important because it a. is the site of gas exchange w/ capillaries b. is an immune secreting cell c. secretes surfectant, preventing alveolar collapse d. secretes mucous , keeping the epithelium moist
