Identify the respiratory muscles that are active during exercise: (select all that are correct- even if only one)• ScalenesAbdominal musclesInternal intercostals• DiaphragmExternal intercostalsChatGPTDuring exercise, the following respiratory muscles are typically active:ScalenesDiaphragmExternal intercostalsSo, you should select Scalenes, Diaphragm, and External intercostals as correct options.For maximum efficiency in offloading oxygen at exercising muscles: (Select all the correct choices, even if only one.)The temperature should be slightly lower than normal body temperature• The PCO2 should be approximately 30 mmH• The pH should be slightly acidic• The oxygen-haemoglobin binding curve should shift to the leftChatGPTFor maximum efficiency in offloading oxygen at exercising muscles, the following factors should be considered:The pH should be slightly acidic.The oxygen-hemoglobin binding curve should shift to the right.So, you should select "The pH should be slightly acidic" and "The oxygen-hemoglobin binding curve should shift to the right" as correct choices.Most of the carbon dioxide in the blood is transported as:O carbinohaemoglobinO bicarbonate ionsO solute dissolved in plasma• solute dissolved in the cytoplasm of red blood cells• carbonic acidChatGPTMost of the carbon dioxide in the blood is transported as "bicarbonate ions."3 / 3When 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 decreasesChatGPTWhen the diaphragm and external intercostal muscles contract, the following condition occurs: "intrapulmonary pressure decreases."
