| Question | Answer |
|---|---|
| urine production occurs in the ____ | kidney lobe |
| ___ collects urine produced by a single kidney lobe | minor calyx |
| ___ is a microscopic structure that performs the essential functions of the kidney | nephron |
| 85 percent of all nephrons are _____ and they are located within the superficial cortex of the kidney. They are the most abundant nephrons | cortical |
| ___ have long nephron loops that extend deep ito the renal medulla | juxtamedullary nephrons |
| the nephron consist of a ____ and a ___ | renal corpuscle, renal tubule |
| protein free solution that is similar to blood plasma | filtrate |
| the renal corpuscle is a spherical structure consisting of ____, and a capillary network aka the ___ | glomerular capsule, glomerulus |
| ____ is responsible for reabsorbing nutrients from the filtrate, now known as ____ | PCT "proximal convoluted tubule, tubular fluid |
| ____ is primarily responsible for the establishment of an osmotic gradient in the renal medulla | nephron loop |
| ___ makes further adjustments in the composition of the tubular fluid though a combination of secretion and re-absorption | DCT "distal convoluted tubule" |
| ___ carries tubular fluid though the osmotic gradient in the renal medulla | collecting duct |
| ___ a series of tubes that carry tubular fluid away from the nephron. Each nephron empties into this system | collecting system |
| ___ collects tubular fluid from multiple collecting ducts and delivers it to a minor calyx | papillary duct |
| in a juxtamedullary nephron, the peritubular capillaries are connected to the ____, long strait capillaries that parallel the nephron loop | vasa recta |
| ____ delivers blood to a network of peritubular capillaries, which surround the entire renal tubule | efferent arteriole |
