Osmoregulation

Question 1

osmoregulation

Answer 1

excretory system

Answer 2

removes nitrogenous waste products

Question 3

nitrogenous wastes

Answer 3

ammonia, urea, uric acid, and creatinine

Question 4

metanephridia

Answer 4

osmoregulatory/excretory organ: selectively reabsorbs or excretes soluble materials from hemolymph or plasma

Question 5

kidney

Answer 5

Filter Plasma, and eliminate Urea and excess Ions, but
recover H20, and recover Amino acids, Glucose , essential Ions such as
Na+, K+. and Ca++

Question 6

sodium

Answer 6

ion, Na+

Question 7

potassium

Answer 7

ion, K+

Question 8

calcium

Answer 8

ion, Ca++

Question 9

amino acids

Answer 9

make polypeptides to make proteins

Question 10

nucleotides

Answer 10

organic anion to make dna/rna

Question 11

glucose

Answer 11

sugar

Question 12

isoosmotic

Answer 12

inside and outside of organism are the same

Question 13

osmoconformer

Answer 13

an osmoconformer changes concentration of organic molecules to match isoosmotic environment.

Question 14

Osmoregulator

Answer 14

maintain distinct internal and external osmolarity

Question 15

ammonia

Answer 15

product of broken down nucleotides

Question 16

ureter

Answer 16

connects kidney and bladder

Question 17

bladder

Answer 17

stores urine

Question 18

urethra

Answer 18

allows urine to exit the body

Question 19

renal artery

Answer 19

blood supply to the kidney. branches into afferent arterioles.

Question 20

afferent arteriole

Answer 20

branch off renal artery.

Question 21

renal vein

Answer 21

how deoxygenated blood leaves the kidney

Question 22

renal pelvis

Answer 22

where each nephron releases urine into

Question 23

nephron

Answer 23

one-cell layer thick. connects to afferent arteriole via bowman’s capsule.

Question 24

bowman’s capsule

Question 25

proximal convoluted tubules

Answer 25

closer to bowman’s castle

Question 26

distal convoluted tubule

Answer 26

further from bowman’s capsule. leads to collecting duct.

Question 27

collecting duct

Answer 27

empties into renal pelvis region.

Question 28

glomerulus

Answer 28

the portion of the afferent arteriole that is surrounded by bowman’s capsule

Question 29

filtrate (made at glomerulus

Answer 29

H2O, ions, glucose, amino acids, urea

Question 30

endothelial cells of glomerulus

Answer 30

filtrate moves through this layer of afferent arteriole, past podoycytes, past cell layer of BC, into lumen of BC

Question 31

podocytes

Answer 31

the little spidery things that create a filtration grid across glomerulus.

Question 32

efferent arteriole

Answer 32

leaving bowman’s capsule, merges into a capillary bed in kidney tissue, then into a venule, and then into the renal vein

Question 33

hyperglycemia

Answer 33

glucose in the urine indicates too much glucose not being broken down

Question 34

diabetes miletus

Answer 34

type 1: endocrine pancreas cannot produce insulin
type 2: insulin is not effective on target tissues

Question 35

diuretic pill

Answer 35

they move extra fluid and salt out of the body.
