ureters, urinary bladder, urethra

167
Q

urethra in men carries..

A

urine and sperm

168
Q

nitrogenous waste from…or it will form…

A

protein digestion is toxic and must be removed or it will form ammonia.

169

filtering blood, creating urine, stabilizing water balance, maintaining blood pressure, producing active form of vitamin D.

170
Q

functional unit of the kidney is…

A

the nephron

171
Q

nephrons are a…(mattias - trash)

A

system of microscopic tubes that use pressure to remove wastes and reabsorb important molecules and water.

172
Q

blood enters the kidneys full of…

A

waste from protein metabolism. goes from nephron capillary to renal artery, then to glomerulus, where stuff is filtered out of blood. then moves through tubule. water is reabsorbed through capillaries back into the blood

173
Q

filtrate is….(WUGS)

A

water, urea, glucose salts and other small molecules

174
Q

what is the final product in tubule?

urine

175
Q

bladder has sensors that communicate with the..

A

CNS

176
Q

urine is composed of…(mostly…)

A

95% water, urea, salts and excess organic molecules

177
Q

how do kidneys maintain blood pressure? (can just change amount w/…)

A

by controlling the volume of blood. secreted hormones from kidneys constrict or dilate blood vessels, resulting in the need to increase or decrease bp.

178
Q

how do kidneys help control production of RBCs? - this isn’t correct..check.

A

cardiovascular pumps blood into kidneys through renal artery, pressure of blood helps the glomerulus filter out wastes and return nutrients through renal vein to the blood. kidneys also produce renin, hormone that regulates bp by retaining or removing water and salt.

179
Q

innate 3 lines of defense (skin inflamed by nymph)

A

1) skin, mucus, secretions 2) phagocytes, specific proteins and inflammatory response 3) adaptive immunity - lymphocytes (B and T cells).

180
Q

functions of immune system

A

prevents entry of pathogens - prevents entry, signaling, and targeting.

181
Q

pathogens enter the body through…(duri)

A

digestive, urinary and reproductive. injuries.

182
Q

where do B and T cells reside?

A

in the lymph

183
Q

185
Q

cellular barriers (good bugs)

A

186
Q

first response if a pathogen makes it into your body…(fire, mast, and danny)

A
