Define Hypoxic Drive? - Answer✔️✔️-A form of respiratory drive in which the body uses
oxygen chemoreceptors instead of carbon dioxide receptors to regulate the respiratory
cycle. Normal respiration is driven mostly by the levels of carbon dioxide in the arteries,
which are detected by central chemoreceptors, and very little by the oxygen levels. An
increase in carbon dioxide will cause chemoreceptor reflexes to trigger an increase in
respirations.
What is Pursed-Lip Breathing - Answer✔️✔️-A breathing technique designed to make
your breaths more effective by making them slower and more intentional. You do this
after inhaling by puckering your lips and exhaling through them slowly and deliberately,
often to a count.

What is the Renin-Angiotensin System (RAS)? - Answer✔️✔️-A hormone system that
regulates blood pressure and fluid and electrolyte balance.
What happens in the Renin-Angiotensin System when renal blood flow is reduced? -
Answer✔️✔️-The juxtaglomerular cells in the kidneys convert the precursor prorenin
(already present in the blood) into renin and secrete it directly into circulation.
What happens after Prorenin is converted into renin and secreted into circulation? -
Answer✔️✔️-Plasma renin then carries out the conversion of angiotensinogen, released
by the liver, to angiotensin I. Angiotensin I is subsequently converted to angiotensin II
