100

This hormone is released from the posterior pituitary to decrease urine output.

What is ADH?

100

This muscle is primarily responsible for quiet inspiration.

What is the diaphragm?

100

This nephron structure collects the filtrate immediately after glomerular filtration.

What is Bowman's capsule?

100

This receptor detects changes in arterial blood pressure.

What is a baroreceptor?

100

This organ system removes carbon dioxide from the body.

What is the respiratory system?

200

These thyroid cells produce T3 and T4.

What are follicular cells?

200

This gas is the primary stimulus controlling breathing under normal conditions.

What is carbon dioxide?

200

This nephron segment reabsorbs the greatest amount of filtered water.

What is the proximal convoluted tubule?

200

This hormone causes blood vessels to constrict during RAAS activation.

What is angiotensin II?

200

This ion combines with hydrogen ions to help buffer blood pH.

What is bicarbonate?

300

This hormone is released when blood calcium levels decrease.

What is parathyroid hormone (PTH)?

300

Hyperventilation causes blood levels of this gas to decrease.

What is carbon dioxide?

300

This nephron segment is the primary site where aldosterone acts.

What is the distal convoluted tubule?

300

This mechanism regulates blood pressure within seconds.

What is the baroreceptor reflex?

300

This kidney function helps remove excess hydrogen ions from the body.

What is proton secretion?

400

This endocrine gland receives hormones through the hypothalamic-pituitary portal system.

What is the anterior pituitary?

400

These receptors detect low oxygen levels in arterial blood.

What are peripheral chemoreceptors?

400

This nephron segment becomes more permeable to water in the presence of ADH.

What is the collecting duct?

400

This hormone increases blood volume by increasing sodium reabsorption.


What is aldosterone?

400

This enzyme rapidly converts carbon dioxide and water into carbonic acid.

What is carbonic anhydrase?

500

Unlike the anterior pituitary, this pituitary lobe does not synthesize its own hormones.

What is the posterior pituitary?

500

When intrapulmonary pressure becomes greater than atmospheric pressure, this occurs.

What is exhalation?

500

These specialized kidney cells monitor sodium chloride concentration in tubular fluid.

What are the macula densa cells?

500

This kidney enzyme begins the RAAS cascade.

What is Renin?

500

This organ system provides the long-term regulation of blood pH.

What is the urinary (renal) system?
