Question

22 multiple choice 2 points
which of the following is a characteristic associated with lesser lung compliance?
easier to inspire
elastic fibers in lung
surfactant
greater surface tension

23 multiple choice 2 points
chyme is:
a hormone that stimulates stomach acid production.
partially digested food mixed with gastric juices.
a protein produced by the small intestine.
a digestive enzyme produced in the stomach.

24 multiple choice 2 points
which is the primary function of the proximal convoluted tubule (pct)?
glucose secretion
urea excretion
sodium reabsorption

Explanation:

Analyze lung compliance characteristics

Lesser lung compliance means the lungs are stiffer and harder to expand. High surface tension in the alveoli resists expansion, thereby reducing compliance.

Define chyme composition

Chyme is the semi-fluid mass of partially digested food mixed with acidic gastric secretions expelled by the stomach into the duodenum.

Identify primary function of the proximal convoluted tubule

The proximal convoluted tubule (PCT) is responsible for reabsorbing the bulk of filtered solutes, with sodium reabsorption being its primary active transport driver.
