State the three factors that increase the release of oxygen in tissues and how cell respiration is a determining factor for oxygen release.Selected Answer:Oxgen is transported through red blood cells, the protein, hemoglobin and mineral, iron within the blood. When blood passes through tissues with low PO2 the bond breaks and oxygen is released. Oxygen is also released when blood passes through tissues with high PCO2, and tissues with high temperature. Active tissues have a higher need for energy and are undergoingcell respiration at a faster rate than inactive tissues. Oxygen is required for synthesis with glucose in the cell respiration process.Correct Answer:Cell - red blood cell; Protein - hemoglobin; Mineral - iron; Factors: Tissues with low PO2 (low oxygen concentration), tissues with high PCO2 (high concentration of carbon dioxide, thus lower pH), and tissues with high temperature (usually active tissues). Activetissues have a higher need for energy and are undergoing cell respiration at a faster rate than inactive tissues. Oxygen is required for synthesis with glucose in the cell respiration process.Response Feedback:[None Given]Question 8Needs GradingYou are making a list of vital organs we cannot live without. Should you include the larynx on your list? Explain why or why not?Selected Answer:Yes, the larynx should be included on the list.The larynx contains the epiglottis, it closing over the top of the larynx to keep saliva or food during swallowing. If the opening to the larynx were to remain open during swallowing, the lungs would fill with food or saliva, making them unable to be filled with air when we breath.Correct Answer:The larynx should be included on the list. The uppermost cartilage of the larynx is the epiglottis. It is responsible for closing over the top of the larynx to prevent the entry of saliva orfood in to the larynx during swallowing. If the opening to the larynx were to remain open during swallowing, the lungs would fill with food/drink/saliva, therefore rendering them incapable of filling with air during inhalation. If this were to happen, an individual would "drown"/"suffocate" due to inability to exchange respiratory gases.Response [None Given]
Feedback:Question 9Needs GradingIdentify the processes depicted: 1) O2 is inhaled --> alveoli --> pulmonary capillaries --> pulmonary veins --> L atrium --> L venticle --> aorta --> systemic arteries --> systemic capillaries --> O2 diffuses to systemic tissues 2) CO2 in systemic tissues --> systemic capillaries --> systemic viens --> inferior/superior vena cava --> R atrium --> R ventricle --> pulmonary arteries --> pulmonary capillaries --> CO2 diffuses to alveoli --> CO2 is exhaled.Selected Answer:1. External respiration2. Internal respirationCorrect Answer:1) External respiration; 2) Internal respirationResponse Feedback:[None Given]Question 10Needs GradingAre the functions of the medulla's inspiration and expiration center necessary for normal respiration? Explain (in as much detail as you can) why or why not -- addressing both centers in your response and the ultimate purposes they serve.
