Microscopic Nephron Anatomy Flashcards
What is A?
Bowman’s Capsule
Bowman’s capsule surrounds the glomerular capillary loops and participates in the filtration of blood from the glomerular capillaries.
What is B?
Glomerulus
The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.
What is C?
Renal corpuscle
The renal corpuscle is responsible for the filtration of the plasma. It contains two structures: the glormerulus and Bowman’s capsule.
What is D?
Proximal convoluted tubule (PCT)
Passive (permeable to): water, chloride ions, potassium ions, urea.
Active (permeatble to): Na+, HCO3−, glucose, amino acids, proteins, phosphate, sulfate, Mg2+, Ca2+, uric acid
What is E?
Descending limb of Henle (DLH)
To concentrate the salt in the interstitium, the tissue surrounding the loop. Its descending limb is permeable to water but completely impermeable to salt, and thus only indirectly contributes to the concentration of the interstitium.
What is F?
Thick ascending limb of Henle (TAL)
Passive (permeable to): urea
Active (permeable to): Na+, Cl−
What is G?
Henle (nephron) loop
Passive (permeable to): Na+, Cl−, urea
What is H?
Thin ascending limb of Henle (tALH)
Passive (permeable to): Na+, Cl−, urea
What is I?
Renal tubule
One of millions of tiny tubes in the kidneys that returns nutrients, fluids, and other substances that have been filtered from the blood, but the body needs, back to the blood.
What is J?
Distal convoluted tubule (DCT)
Active transport: Na+, Cl−, sulfate, uric acid
Passive transport: water
What is K?
Collecting duct
It allows the generation of maximally concentrated urine due to osmotic water equilibration.
What is J?
Papilla of renal pyramid
Collecting ducts converging to form a papillary duct to channel the fluid.
