PHYSIOLOGY OF THE URINARY SYSTEM - Overview of kidney function and Filtration Flashcards
What are the chief functions of the kidneys?
To process blood and form urine
What is the basic functional unit of the kidney and what does it form?
Nephron
forms urine through three processes
What are the 3 processes of the nephron in forming urine?
Filtration
Reabsorption
Secretion
What is the movement of water and solutes from the plasma in the glomerulus into the capsular space of the Bowman’s capsule?
Filtration
What is the movement of molecules out of the renal tubule and into the peritubular blood?
Reabsorption
What is the movement of molecules out of the peritubular blood and into the renal tubule for excretion?
Secretion
What is the first step in blood processing that occurs in the renal corpuscles?
Filtration
From the blood in the glomerular capillaries what is filtered into the Bowman’s capsule? Where does it take place?
water and solutes
It takes place through the glomerular-capsular membrane
Filtration occurs due to existence of what????
a pressure gradient
What occurs rapidly due to the increased number of fenestrations?
Glomerular capillary filtration
What two things are directly related to systemic blood pressure
Glomerular hydrostatic pressure and filtration
