19)
Proteins
yield the highest amount of e
nergy per gram when metabolized.
20)
Peyer’s patches are lymphatic foll
icles located in the small intestine.
21)
The volume of air that can be exhaled beyond tidal volume is called the vital capacity.
22)
Secretion of gastrin is stimulated by norepinephrine, which is released by sympathetic
neurons.
23)
Bicarbonate ions are secreted
into the lumen of the stomach along with hydrogen ions
in order
to buffer
(neutralize)
them.
24)
Parietal cells of the stomach secrete HCl and intrinsic factor.
25)
The volume of air that is moved in and out of the lungs during normal quiet breathing is
called
the alveolar ventilation rate.
26)
Cigarette smoke is the most common cause of lung cancer in the United States.
27)
Calcitonin and PTH act as antagonistic hormones with respect to serum calcium level.
28)
Decarboxylation reactions occur in the Krebs cycle.
29)
Obstru
ction of the hepatopancreatic sphincter impairs digestion by limiting the
availability of HCl and bile.
30)
The presence of air in the pleural cavity is known as atelectasis, and is reversed by
drawing air out of the intrapleural space with chest tubes.
Explanation / Answer
19 B - Fats yield the highest amount of energy when metabolized
20 A - they are the small lymphatic tissue masses found throughout the ileum region of the small intestine.
21 B - it is the expiratory reserve volume that is the additional amount of air that can be expired from the lungs by determined effort after normal expiration.Vital capacity is the maximum volume of air exhaled after a deep breath
22 B. epinephrine is the stimulatory factor for gastrin secretion.
23 A
24.A.
25. B. the volume of air entering or leaving the lungs in a normal breathing cycle is called the tidal volume. alveolar ventilation rate is the rate of air flow that the gas exchange areas of the lung(alveoli) encounter during normal breathing
26.A
27.A PTH which increases Ca 2+ in the blood by increasing Ca 2+ absorption in the intestines and reabsorption in the kidneys and calcium release from the bones. Whereas calcitonin leads to decrease in serum calcium levels by inhibiting the breakdown of bone matrix and both together maintain the mineral homeostasis
28.A.- when alpha-ketoglutarate loses a carbon dioxide molecule and coenzyme A is added in its place(step 4)
29. B
Obstruction of the hepatopancreatic sphincter impairs digestion by limiting the availability of pancreatic juice and bile.
30 B
Pneumothorax is the presence of air in the pleural cavity and is reversed by drawing air out of the intrapleural space with chest tubes.when both lungs are affected by a pneumothorax.it leads to a collapsed lung, known as atelectasis
