Solved in 2 steps
- The pulmonary trunk carries: low-oxygen blood from the lungs to the heart O oxygenated blood from the heart to the lungs O low-oxygen blood from the heart to the lungs oxygenated blood from the lungs to the heartWhat term best describes the exchange of oxygen and carbon dioxide at the interface between the systemic capillaries and the peripheral tissues? Cellular respiration External respiration Internal respiration VentilationWhich of the following is the inferior boundary of the nasopharynx? O hyoid bone internal nares uvula O cricoid cartilage
- Pulmonary arterioles respond to different factors than systemic arterioles because in the lungs, the blood supply is receiving oxygen and delivering carbon dioxide, while in the systemic circulation, it is delivering oxygen, and receiving carbon dioxide. In the pulmonary circuit, arterioles will dilate in well-ventilated areas of the lungs to increase the rate of exchange between capillaries and well-ventilated alveoli. However, in poorly ventilated areas of the lungs, arterioles will constrict in order to re-route blood to well-ventilated areas. Now consider our case of pulmonary oedema, and how that will impact circulation in the pulmonary circuit. (Select two answers). Pulmonary arterioles will dilate Pulmonary arterioles will constrict O Pulmonary vascular resistance will increase O Pulmonary vascular resistance will decreaseIn which of the following erythropoetic cells does hemoglobin synthesis begin? Oa Polychromatophilic erythroblast Ob Proerythroblast oh 3cOrthochromatic erythroblast Od Reticulocyte e. Basophilic erythroblastHelp me please
- Capillary in lung) Alveoli in lung Capillary in tissue Poz PC0₂ Poz = 40 mm Hg Pco₂ = 46 mm Hg 100 mm Hg = 40 mm Hg 0₂ = CO₂ Cells in body Refer to the accompanying figure. Which statement is accurate? CO₂ will diffuse from the alveoli into the capillaries. CO₂ will diffuse from the capillaries into the tissues. O₂ will diffuse from the capillaries in the tissues to the capillaries in the lung. O₂ will diffuse from the alveoli into the capillaries. O₂ will diffuse from the tissues into the capillaries.Fluid shift into the extravascular spaces in bilateral lower extremities is often indicative of MI. pulmonary edema.
