what is the function of the urinary system? it is the organs in the body that filters out excess fluids and other substances from the bloodstream
what is urine, and where is it produced? urine is a product of the kidney, and it collects in the bladder and excreted through the urethra
what organs comprise the urinary system? the urinary systems include the kidney, ureters, bladder and urethra
where are the kidneys located? they are located at the posterior abdominal cavity
what are the functions of the kidney? regulating the volume of blood volume, regulating the concentration of waste products in the blood, regulating the concentration of ions in the plasma
The two major regions of the kidneys are? medulla and cortex
urine flows from to the urinary bladder from the kidneys through? the ureter
The structure of the kidney where urine is formed is called the? nephron
What is the fluid that enters the glomerulas? the blood
The fluid that enters the glomerular capsule is formed from the? plasma
what are the structures that lead away from the glomerular capsule? proximal convoluted tubule, loop of henle
The kidney is referred to as a? excretory organ
What kind of waste does the kidney excrete? it excretes nitrogenous waste
The kidney acts as a homeostatic organ because it maintains? electrolytes, acid-base and the fluid balance of the blood
Each kidney is surrounded and held in place against the muscles of the trunk wall by its ____ renal fascia
The outer region of the kidney is known as ____ renal cortex
Renal pyramids are separated by extensions of cortex-like tissue called the __________ renal columns
As blood flows toward the kidney, it travels from the renal artery into vessels called the ____ segmetal arteries
A urinary output of less than 100 mL per day is called __________ anuria
The process of filtration occurs in a specific structure in the nephron called the __________ glomerulus
what is the function of kidneys? manufacture urine, convert vitamin D from its inactive to its active form, dispose of metabolic waste products, regulate blood volume
Which one of the following terms describes the location of the kidneys: A) suprarenal B) retroperineal C) adrenal D) intraperitoneal E) retroperitoneal retroperitoneal
The kidneys are aided in excretion of fluids by the ______ the skin and hair
The triangular regions of the kidneys that are striped in appearance and separated by the renal columns are the ____ renal pyramids
Each kidney contains about ____ nephrons 1 million nephrons
The enlarged, cup-shaped closed end of the renal tubule that completely surrounds the glomerulus is called the _____ Bowman's capsule
Starting from the glomerular capsule, the correct order of the renal tubule regions is _____ proximal convoluted tubule, loop of Henle, distal convoluted tubule

Of the capillary beds associated with each nephron, the one that is both fed and drained by arterioles is the ____ glomerulus
The peritubular capillaries arise from the __________, which drains the glomerulus efferent arteriole
The nonselective, passive process performed by the glomerulus that forms blood plasma without blood proteins is called ____ filtration
Uric acid, a nitrogenous waste product, results from the metabolism of ___ nucleic acids
The presence of pus in urine is called? pyuria
Which one of the following substances is normally found in urine: A) blood proteins B) red blood cells C) hemoglobin D) white blood cells E) creatinine creatinine
The bladder is able to expand as urine accumulates within it due to the presence of _____ transitional epithelium
Urine is transported from the bladder to the outside of the body by the ____ urethra
The main hormone that acts on the kidneys to regulate sodium ion concentration of the extracellullar fluid (ECF) is aldosterone
Antidiuretic hormone prevents excessive water loss by promoting water reabsorption in the collecting duct
Functional kidneys develop within the womb by the third month after conception from the __________ set of tubule systems. third
