Clears the blood of many waste products. Play a vital role in maintaining electrolyte, water, and acid-base balances in the body.
Filtering unit of the kidney. Filters blood, removing wastes and helps maintain homeostasis of the body
Bed or collection of capillary vessels within the kidney involved in the initial formation of urine. High pressure forces water, glucose, vitamins, amino acids, urea, salts and ions into Bowman's capsule
Bowman's capsule filters out what out of blood?
Water, glucose, vitamins, amino acids, urea, salts, and ions. Liquid then passes through renal tubule with a surrounding capillary that reabsorbs needed substances in Loop of Henle
Which materials does the collecting duct deliver to the ureter?
Waste molecules and excess water
Role of ureters and bladder
The bladder is the storage tank for urine and the ureters are what allows the urine (tubes) to leave the kidney into the bladder.
Conveys urine from the bladder to the outside
Organs of excretion
Lungs with alveoli removes Co2 and water in breath
Skin with sweat glands is protective cover and helps cool body
Kidneys with nephrons is body filter and controls water and salt loss, removes urea from blood
Kidney set up
blood vessels to and from kidney, ureters from kidney to bladder, urethra from bladder to outside of body
Excretory System: 3 parts
Respiratory and circulatory with alveoli take CO2 out of blood, breathed out of lung.=gaseous waste
Digestive system food wastes eliminated through the anus=solid waste, feces
Urine with wastes from blood from kidney filtering-excretory system and sweat from integumentary system=liquid waste (urine and sweat)
Artery brings blood to kidney, vein takes it away from kidney
Large artery that carries blood wastes to the kidneys. Divides into renal arteries that bring blood to each kidney.
Clean blood leaves the kidney through the...,.
renal vein which empties into the inferior vena cava and this goes back to the heart
Loop of Henle
Where needed substance are reabsorbed into the blood after being filtered out of the blood by the kidney and the rest goes into the renal tubule=urine or waste liquid. This goes to renal pelvis, bladder and out.
Homeostasis and kidneys
Kidneys remove toxic wastes like protein breakdown ammonia and urea. They also control amount of sodium in blood by absorption and regulat the pH bu filtering out hydrogen ions and allowing bicarbonate to be reabsorbed./removal from blood.
Is not filtered by the blood by the kidneys but diabetics may have excess levels of glucose in their urine.
