Excretoin Flashcards
What organ of an earthworm resembles our nephron?
nephridia
nephoron-mammal/verdebrates
The difference between excretion and egestion/defecation
EXCRETION INCLUDES BALANCING (HOMEOSTASIS) REACTION PRODUCTS, TOXINS, MOLECULES IN EXCESS AND TOO LITTLE.
EGESTION INCLUDES MOLECULES THAT ARE EXITING YOUR ANUS CHEMICALLY UNCHANGED
what must urea be mixed with in order to be excreted by the nephron and skin?
water
What is deamination?
the act of getting rid of the amino component in a protein
In what forms are nitrogenous wastes excreted?
ammonia, urea or uric acid
What would happen if humans excreted ammonia?
it would destroy their cells
pramecium
protoza, unicellular etc.
Is carbon dioxide treated as a acid or a base?
acid
The bladder of humans empties to the outside by means of the …?
urethra
The reason why there are a lot of mitochondria’s around the tubule cells of nephrons suggest tthat…
there is a lot of active transport.
mitochondria-ATP-active transport
in humans, which organ excretes water and dissolved salts?
skin
The human kidneys have a function similar to the function of the contractive vacuole of the protoza in that both
help to maintain the water balance of the organism
contractile vacuole
bolism is calle
hte remoal of undigested food through teh anus is known as
egestion
wastes produced by an organism reactions as it carries on its life processes are called ____ wastes
excretory
the removal of the waste products of chemical reactions/metabolism is called
excretion
the energy for the active transport of waste products is supplied by
respiration
the external openings of the grasshopper’s trachea are called
spiracles
uric acid is not poisonous to cells because it is
soluble/non toxic
hydra excretes nitrogenous wastes in the form of
ammonia
in teh earthworm, nitrogenous wastes are excreted through pairs of tubes called ____ and Co2 diffuses through the ___
nephridia
skin
in the grasshopper, nitrogenous wastes are removed from body fluids by structures called _____ and Co2 is carried to the outside by structures called ____
malphigian tubules
trachole tubes
malphigian tubules
The nephrams of the grasshopper
Two wastes excreted through the lungs of humans are
CO2 and water
the structure that filter the urea from teh blood in teh kidney are the..
glomerulus capillaries and bowman’s capsule of the nephron
the liver acts as an organ of excretion by deamination of excess ____ to form the waste prodcut known as ___
amino acid
urea
urea formed in the liver is removed from teh blood in the ___ and ___
nephron
skin
urine is carried from the kidneys to the bladder by the
ureter
the functional unit of the human kidney is hte
nephron
the tube in men and women which discharges urine from the bladder is the
urethra
filtration of materials from the blood int the nephrons occurs at the
glomerulus and Bowman’s capsule
a tiny mass of capillaries in a bowman’s tube is the
glomerulus
the removal of wastes at the nephrons involve
filtration and reabsorption
glucose and amino acids are absopbed back into the blood by
active transport reabsorption
sweating cools the body by
evaporation
where does the carboxyle component go to after deamination
the mitochondria for aerobic respiration
ammonea
most toxic
oceanic
urea
slightly toxic
humans
mix w water
urine is a combination of?
urea and water
uric acid
not toxic
dry animals
protect bird and reptile babies
lung:pulmonary::kidney:___
renat
the artery goes from what to what?
heart to kidney
the vein goes from what to what?
kidney to heart
Describe the path of the urea
blood-renal artery-kidney-ureter-(blood) renat vein (urea)bladder
What doesn’t enter the glomerulus capillaries?
RBC, platelets, large protein, WBC
What get reabsorbed through active transport?
glucose, amino acid
what diffuses out of the Loop of Henle?
water
what passes through the loop of henle?
urea
what is the role of the liver?
make urea, bile, increase surface area of lipids detoxification glycogen bonds
what makes up bacteria paradise?
water, sodium chloride and urea
what is the role of your kidney?
filtration, reabsorption
what happens to the glucose that goes over the absorption threshold?
urine
why is there an absorption threshold?
nephram cells can only do so much pumping
insulin breaks down what?
glucose
what does the ADH do?
hormone that increases water secretion
protists have what kind of nitrogen waste?
ammonia
what kind of nitrogen waste do micro organisms have?
ammonia
in a protist, where is the water kept?
contractile vacuole
do hydras use active transport or osmosis?
active transport
do protists use active transport or osmosis?
osmosis
what is urea made from?
carbon dioxide and water
where is the urea released from in earthworms?
their moist skin
human:nephram::earthworm:
nephridium
human:urine::earthworm:
nephridiopore
human:bowman’s capsule::earthworm:
nephrotsome
Where is the protein broken down into amino acids?
the liver
In what forms are nitrogenous wastes excreted?
ammonia, urea or uric acid
What would happen if humans excreted ammonia?
it would destroy their cells
pramecium
protoza, unicellular etc.
Is carbon dioxide treated as a acid or a base?
