Functions of the nephron Flashcards
A)
Hey What is the liquid that collects in the Bowmans capsule?
Plasma minus blood proteins
D)
Tubular excretion occurs where?
At the distal convoluted tubule
Blood pressure is…
Very important
C)
Since the body cannot afford to lose all of its water, it must reabsorb into the…
Blood
The loop of Henle creates a high osmotic pressure in the….
Medulla
A)
First, blood enters the glomerulusWhich is surrounded by the Bowmans capsule. What occurs here?
Pressure filtration occurs
D)
Excess molecules in the blood such as H+ ions, histamine, penicillin and ammonia are secreted into it to be all from blood, they are for helping to…
Maintain homeostasis.
Helps maintains blood pH
B)
What occurs At the proximal convoluted tubule?
Selective reabsorption
C)
What is result from the process of re-absorption of water into the blood?
The negative ion (CI-) And water follows the sodium by osmosis, to even out electrical and concentration gradients
Water is reabsorbed along the…
Entire length of the nephron. Therefore urine is concentrated
What are the filter the blood components?
Water
Nutrients
Nitrogenous waste
Salt (ions)
When blood pressure is too low and filtration does not occur, a hormone called ________ is released from a specialized tissue in the _________.
Rennin, Glomerulus.
This causes the constriction of the Glomerulus, thus, the blood pressure is increased to an adequate level
The fluid going up the distal side of the loop of Henle had a greater [____________ of wastes and little nutrient value
Concentration
What are the non-filtered blood components?
Formed elements- (blood cells and nitrogenous wastes platelets)
Proteins
E)
Concentrated urine from the collecting tubule collect and go to the…
Renal pelvis
C)
During the reabsorption of water into the blood, the cells of the loop of the Henle actively pump…
NA+ out of the tubule and k+ into the nephron.
What does not occur if blood pressure is too low?
Filtration will not occur
The blood in the capillaries are __________ to the fluids in the fluids spaces.
Hypertonic
B)
Selective reabsorption’s required nutrients,
glucose, amino acids, vitamins, minerals, salt molecules and some water are reabsorbed into the peritubular capillary network
A)
Once pressure filtration occurs, water, nutrients and wastes enter the Bowmans capsule. What does not enter?
Large organic molecules do not enter they are filtered
B)
Selective reabsorption requires…
ATP
