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

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

Q

both passive and active immunity can be..(fake)

A

induced artificially

198
Q

rapid treatment, anti-venom, from a snake bite is a form of..(the snake is passive)

A

passive immunity - the anti-venom was given to you, therefore passive. You didn’t form the antibodies.

199

A

infects helper T cells and prevents them from activating cytotoxic T cells and B cells and prevents adaptive immune from operating

204
Q

you want inflammation to be…

A

temporary and localized

205
Q

opsonins

A

tags placed on non-self cells. ex - antibodies

206
Q

histamine will..(open sinuses)

A

vasodilate any tissue so more blood can flow in. also makes holes in capillaries bigger so WBCs can get through

207
Q

A

squeeze through the capillaries, ie wbcs when bacteria is detected

208
Q

209
Q

renal arteries allows oxygenated blood to enter…(needs to get to…)

A

targets intestines, increases reabsorption of Ca2+.
