Urine Formation
Regulation
Disorders/Dialysis
100
This is shaped like a funnel. It is important to collect filtrate from the nephrons in a kidney
The renal pelvis
100
This substance does not pass through the glomerulus
Proteins/ RBCs
100
The reabsorption of water is dependant on the detection of what?
osmotic pressure
100
If someone has Diabetes Mellitus, they aren't able to move blood sugar into cells. This results in a high _________ of ____________in the nephron.
concentration solutes
200
Drainage from the bladder needs these 2 structures to relax.
Sphincters
200
Urea is formed by what
The combining of ammonia and CO2
200
Aldosterone
This helps to regulate body fluid volume by making the tubule more permeable to ions
200
This can result from a lack of insulin production
What is Diabetes Mellitus
300
This glomerulus is responsible for ____________, while the tubule is responsible mainly for_________________.
Filtration Reabsorption
300
Where is filtration taking place during urine formation in the nephron?
The glomerulus
300
Drinking coffee could result in the body not releasing this substance
ADH
300
If someone is without sufficient ADH and producing a large amount of highly diluted urine it could be a result of this disorder.
Diabetes Insipidus
400
Filtrate travels from the kidney to the bladder through__________, it then exits the bladder through the ___________.
ureters urethra
400
What is the descending loop of henle permeable to and not permeable to?
permeable to water Not permeable to ions
400
What will happen to our blood pressure when there is an increased reabsorption of water?
Will increase
400
Semi-permeable
Dialysis machines purify blood by passing it through what kind of membrane?
500
Where does deamination occur and what does it create?
The liver ammonia
500
Why is it so important that the ascending loop of Henle actively transports Na+ back into the blood?
To replenish the salty environment of the medulla- so that water can be reabsorbed in the descending loop
500
If the blood is too acidic what should the kidneys secrete and reabsorb to maintain pH balance?
Secrete H+ out of the blood Reabsorb bicarbonate into the blood
500
What is the difference between hemodialysis and peritoneal dialysis?
Hemodialysis- takes place outside the body Peritoneal- dialysis fluid inserted into the abdominal cavity
