excretory system

Question 1

what does the excretory system does

Answer 1

excretes metabolic waste from the body

Question 2

most toxic waste compound

Answer 2

AMMONIA it is produced when the amigo acids from proteins are used for energy. ammonia converts to urea

Question 3

excretion

Answer 3

the process by which metabolic waste are eliminated to maintain homeostasis

Question 4

excretory system organs

Answer 4

1. skin
2. lungs
3. liver
4. kidneys

Question 5

skin

Answer 5

the skin excretes excess water, salts, and a small amount of urea in sweat.

Question 6

lungs

Answer 6

when you exhale your lungs excrete carbon dioxide and small amounts of water vapor.

Question 7

liver

Answer 7

conversion of potentially dangerous nitrogen wastes, into less toxic urea.

Question 8

kidneys

Answer 8

major organs of excretion are the kidneys.
through a complex filtering process, the kidneys remove excess water, urea, and metabolic wastes from blood.
the kidneys excrete urine. ureters transport urine form the kidneys to the urinary bladder where the urine is stored and it is released through the urethra

Question 9

transportation of urine

Answer 9

ureters transport urine form the kidneys to the urinary bladder where it is stored, and it is released to the urethra

Question 10

how do the kidneys clean the blood

Answer 10

as waste-laden blood enters the kidney through the renal artery, the kidney removes urea, excess water and minerals, and other waste products. the clean filtered blood leaves the kidney through the renal vean and returns to circulation.

Question 11

nephrons

Answer 11

nephrons are where most of the work of the kidney takes place.

Question 12

proceses of blood purification

Answer 12

filtration and reabsorption

Question 13

where does the filtración of blood takes place

Answer 13

mainly in the glomerulus

Question 14

glomerulus

Answer 14

a glomerulus is a small but dense network of capillaries encased in the upar end of each nephron by the bowmans capsule

Question 15

filtrate

Answer 15

the material that is filtered from the blood. the filtrase contains water, urea, glucosa, salts, amigo acids, and some vitamins

Question 16

re absorption

Answer 16

nearly 180 liters of filtrase pass from the blood into nephron tubules every day.

Question 17

reabsorption

Answer 17

the process by which water and dissolved substancies are taken back into the blood

Question 18

loop of henle

Answer 18

the loop of Henle is responsible for conserving water nd minimizing the volume of the filtrate. the waste material now called urine remains in the tabule emptied into a collecting duct

Question 19

functions of the kidneys

Answer 19

besides remoiving waste, the kidneys also mantain blood ph and regulase the water content of the blood.

Question 20

glands

Answer 20

glands release hormones that also influence kidney function. for example, if you have not consumed enough fluids, your pituitary gland releases antidiuretic hormone (ADH)

Question 21

The presence of what can be indicators of disease

Answer 21

proteína and glucose sucos as dangerously high blood pressure or diabetes

Question 22

kidney disorders

Answer 22

kidney stones
kidney damage
kidney failure

Question 23

kidney stones

Answer 23

calcium, magnesium or cric acid salts crystallizeand form kidney stones. kidney stones block a ureter. kkidney stones are often treated usin ultrasound waves. the sound waves pulverize the stones into smaller fragments, which are eliminaste with urine

Question 24

kidney damage

Answer 24

most cases of kidney damage are related to high blood pressure and diabetes. excesivo blood pressure amagues delicate filtering mechanism and high blood sugar levels cause the kidneys to filtre more blood than normal. over time, the tubules weaken and the kidneys may fail to keep up with the demands.

Question 25

kidney failure

Answer 25

when kidneys can no longer clanes the blood and mantain a state of homeostasis in the body.
a kidney failure must receive dialysis or undergo a kidney transplant
