- The anatomic dead space is **a. the volume of the respiratory system, less that of the alveoli b. the volume of the whole respiratory system c. equal to the vital capacity d. the total volume of the alveoli
- If the heart rate is 100 beats per minute and the stroke volume is 70 ml, how many liters of blood flow through all the pulmonary veins per minute a. 3. b. 70 **c. 7 d. 35

- Inadequate amounts of pulmonary surfactant can cause a. bronchitis b. laryngitis **c. atelectasis d. pulmonary embolism
- Cystic fibrosis, Duchenne's muscular dystrophy, Huntington's disease, and hemophilia are all caused by a. loss of a chromosome **b. defective genes c. one chromosome too many d. loss of part of a chromosome

- The ------- receptor is a nuclear protein that can act as a transcriptional activator **a. cortisol b. insulin c. growth hormone d. beta-adrenergic
- Receptors for insulin and some cytokines are **a. tyrosine kinases b. phospholipases c. adenylate cyclases d. ion channel proteins
- A patient with an enlarged thyroid gland is examined. The concentration of thyroxine in the blood is 0.2 mg/dl (normal = 0.8-2.7 mg/dl). Given these two pieces of information, what is the likely concentration of thyroid-stimulating hormone in the blood (normal = 0.4-4.2 mU/liter) a. 4. b. 0. **c. 18. d. 0.
- Ms A.G. is a 39-year old nurse with a serum cortisol level of 3. micrograms/deciliter (normal is 10-20 micrograms/deciliter). You carry out a test injection of ACTH, but serum cortisol levels remain unchanged at 3.5 micrograms/deciliter. Of the following, which is the most probable explanation for this condition. a. degeneration of the anterior pituitary **b. atrophy of the adrenal cortex c. undersecretion of ACTH d. loss of hypothalamic cortisol receptors
