Osmoregulation Flashcards
osmoregulation
Ion & H2O balance
excretory system
removes nitrogenous waste products
nitrogenous wastes
ammonia, urea, uric acid, and creatinine
metanephridia
osmoregulatory/excretory organ: selectively reabsorbs or excretes soluble materials from hemolymph or plasma
kidney
Filter Plasma, and eliminate Urea and excess Ions, but
recover H20, and recover Amino acids, Glucose , essential Ions such as
Na+, K+. and Ca++
sodium
ion, Na+
potassium
ion, K+
calcium
ion, Ca++
amino acids
make polypeptides to make proteins
nucleotides
organic anion to make dna/rna
glucose
sugar
isoosmotic
inside and outside of organism are the same
osmoconformer
an osmoconformer changes concentration of organic molecules to match isoosmotic environment.
Osmoregulator
maintain distinct internal and external osmolarity
ammonia
product of broken down nucleotides
ureter
connects kidney and bladder
bladder
stores urine
urethra
allows urine to exit the body
renal artery
blood supply to the kidney. branches into afferent arterioles.
afferent arteriole
branch off renal artery.
renal vein
how deoxygenated blood leaves the kidney
renal pelvis
where each nephron releases urine into
nephron
one-cell layer thick. connects to afferent arteriole via bowman’s capsule.
