25
The innermost layer of the kidney to prevent infection from spreading. The capsule is composed of tough fibers, chiefly collagen and elastin (fibrous proteins), that help to support the kidney mass and protect the vital tissue from injury.
Fibrous Capsule
26
Kidney regions?
Renal Cortex, Renal Medulla, Renal Pelvis
27
located at the outer region of the kidney. It appears granular due to the presence of glomeruli
Renal Cortex
28
located in the deeper region of the kidney and it contains the renal pyramids.
Renal Medulla
29
cone-shaped structures responsible for concentrating urine
Renal Pyramids
30
located in the hilum of the kidney. It is a flat-funnel-shaped tube that collects the urine from the calyx and channels it into the ureter.
Renal Pelvis
31
cup-shaped cavity in the kidney that collects urine before it passes into the bladder
Calyx
32
small funnel-shaped chamber that surround the renal pyramids. Urine from the renal papilla drains into the ____
Minor Calyces
33
formed when four or five minor calyces converge.
Major Calyces
34
fundamental and functional unit of the kidney. Each kidney contains approximately one million of this. It is responsible for filtering blood and producing urine.
Nephron
34
initial filtering unit of the nephron.
Renal Corpuscle
35
a network of capillaries where blood is filtered. It is the main filtering unit of the kidney
Glomerulus
36
cup-shaped structure that surrounds the glomerulus and collects the filtered urine
Bowman's Capsule
37
extends from the Bowman’s Capsule and ends when it empties into the collecting duct.
Renal Tubule
38
Subdivisions of the Renal Tubule
Proximal Convoluted Tubule, Nephron Loop, and Distal Convoluted Tubule
39
a large duct that collects urine from the multiple nephrons
Collecting Duct
40
it is about 25 com long muscular tubes that transport urine from the kidney to the urinary bladder. They are lined with smooth muscle that contracts rhythmically, so that the urine can run along their length. They carry the urine from the kidney to the bladder, where it will be temporarily stored.
Ureter
41
- hollow muscular organ that stores urine until it is excreted. It is located in the pelvis cavity and has a capacity of about 500 ml of urine in women and 700 ml in men
Bladder
42
Bladder is lined with a special type of epithelium called ____. It allows the bladder to stretch and expand as it fills with urine
Transitional Epithelium
43
A tube that carries urine from the bladder to the outside of the body. It is shorter in females about 4 cm long and males have about 20 cm in length as it transports both urine and semen during sexual activity
Urethra
44
Blood flows through the kidneys through the
right and left renal arteries
45
originate from the abdominal aorta and enter the renal hila to supply the kidneys
renal arteries
46
Blood coming into the kidney is rich in ____ and ____ and ____
oxygen; nutrients; waste materials
47
Renal capillaries are located?
in and around the nephrons
48
Brings blood to the kidneys; Blood is rich in oxygen, nutrients and metabolic wastes
Renal Artery
49
Blood vessels that drain the kidney. Connect the kidney to the inferior vena cava; Blood has less oxygen, nutrients, and metabolic wastes
Renal Vein
50
_____ take a simple filtrate of the blood and modify it into ____
Nephrons; urine
51
The principle task of the ____ is to balance the plasma to homeostatic set points and excrete potential toxins in the urine
Nephron population
52
Three principle functions
filtration, reabsorption, and secretion
53
waste byproduct formed from excess water and metabolic waste molecules during the process of renal system filtration
Urine
54
Primary function of the renal system is?
to regulate blood volume and plasma osmolarity
55
blood enters the afferent arteriole and flows into the glomerulus
Glomerular Filtration
56
filterable components accumulate in the glomerulus to form the
Glomerular filtrate
57
volume of glomerular filtrate formed per minute by the kidneys; regulated by multiple mechanisms and is an important indicator of kidney function
Glomerular filtration rate (GFR)
58
occurs in the Proximal convoluted tubule (PCT) part of the renal tubule
Tubular reabsorption
59
is the most abundant ion and most of it is reabsorbed by active transport and then transported to the peritubular capillaries
Sodium (Na)
60
In the tubular reabsorption or secretion, ____ and this occurs either by passive or active transport.
Almost all nutrients are reabsorbed
61
are regulated and can be influenced by hormones
Reabsorption of water and some key electrolytes
62
most of the sodium is reabsorbed by active transport and then transported to the
peritubular capillaries
63
Water is also independently reabsorbed into the peritubular capillaries due to the presence of
aquaporins, or water channels
64
The ____ increases as it moves deeper into the medulla
Osmotic gradient
