Alveoli - ANSWERtiny sacs of lung tissue specialized for the movement of gases
between air and blood
pleural cavity - ANSWERspace between the folds of the pleura
Gas exchange - ANSWERthe process of obtaining oxygen from the environment and
releasing carbon dioxide
Larynx - ANSWERvoice box; passageway for air moving from pharynx to trachea;
contains vocal cords
Pulmonary compliance - ANSWERmeasure of the lung's ability to stretch and expand
Expiration - ANSWERbreathing out (exhalation)
Hyperventilation - ANSWERIncreased rate of respirations resulting in lowered blood
levels of carbon dioxide: often results from anxiety
Hypoventilation - ANSWERReduced rate and depth of respirations, resulting in
increased blood levels of carbon dioxide
Apnea - ANSWERabsence of breathing
Bradypnea - ANSWERabnormally slow breathing
Bronchi - ANSWERThe passages that direct air into the lungs
Surfactant - ANSWERchemical produced in the lungs to maintain the surface tension
of the alveoli and keep them from collapsing
Inspiration - ANSWERbreathing in (inhalation)
Broncodilation - ANSWERAn increase in diameter of a bronchiole
Bronchoconstriction - ANSWERReduction in diameter of a bronchus
Nasal Septum - ANSWERA wall of cartilage that divides the nose into two equal
sections
, Cilia - ANSWERThe hairlike projections on the outside of cells that move in a
wavelike manner
Epiglottis - ANSWERA flap of tissue that seals off the windpipe and prevents food
from entering the trachea.
Functions of the Kidney - ANSWER1. excrete nitrogenous waste
2. regulate blood volume
3. regulate electrolyte content
4. helps regulate acid-base balance in blood
5. produce renin which regulates blood pressure
6. produces erythropoietin which regulates rbc production
Bladder - ANSWERElastic, hollow, muscular organ that provides temporary storage
for urine.
Ureter - ANSWERtube that carries urine from the kidney to the urinary bladder
Loop of Henle - ANSWERsection of the nephron tubule that conserves water (returns
water to the blood) and minimizes the volume of the filtrate to the next segment of
the nephron
Bronchodilation - ANSWERDilation of bronchial airways
Increases airflow
Nephron - ANSWERFunctional unit of the kidney, consisting of a glomerulus, renal
tubule, and collecting tubule. Where filtration occurs
Renin - ANSWERAn enzyme secreted by the juxtaglomerular cells when blood
pressure decreases. Renin converts angiotensinogen to angiotensin I.
aldosterone - ANSWERHormone that stimulates the kidney to retain sodium ions and
water. Stimulated by angiotensin II
Glomerular filtration rate - ANSWERAmount of fluid filtered by all the glomeruli of
both kidneys
Sodium Bicarbonate - ANSWERProduced by kidneys, makes blood more alkaline
Components of urine - ANSWERNitrogenous wastes (urea, uric acid, ammonia and
creatinine), and electrolytes (sodium, potassium), and sulfates
Gallbladder function - ANSWERstores bile
Pancreatic Enzymes - ANSWERDigestive enzymes produced by the Pancreas to help
digest fats, starches, and proteins. Secreted into the duodenum
