Document Summary
In the ascending limb of henle"s loop, the interstitial fluid osmolality in a given region of the medulla is 900 milliosmoles. The inspiratory area of the respiratory centre is located in (a) the cerebral cortex (b) the medulla (c) the pons (d) the cerebellum (e) the midbrain. Immediately before entering the respiratory zone, air passes through which of the following structures? (a) alveoli (b) trachea (c) primary bronchi (d) terminal bronchiole (e) respiratory bronchiole. Premature babies are often born without sufficient pulmonary surfactant. A patient suffering from respiratory problems was given a forced vital capacity test. It was found that the patient a vital capacity of 3. 5 litres and a forced expiratory volume (fev-1) of 3. 1 litres. Your urine collected over 24 hours had a volume of 1. 5 litres. Your urine contained 0. 8 g of sodium per litre. Using this information answer the next 3 questions: what was your 24 hour filtered load for sodium? (a) (b) (c)
