Nephrons
Each kidney has one million of these filtering units
Renal arteries
These vessels deliver blood from the aorta to the kidney for filtration
Renal vein
Filtered blood leaves the kidney through these vessels and returns to the heart via the IVC (inferior vena cava)
Efferent arterioles
Small tubes where urine leaves from the nephron
Glomerulus
Tuft of capillaries in the nephron where filtration
Ureter
10-12 inch tubes through which urine flows from the kidney to the bladder
Bladder
Sac lined with muscular folds that holds urine
Peritubular Capillaries
Tiny blood vessels surrounding the collecting tubules which reabsorb needed nutrients
Urethra
Exit tube for urine from the body
Renal cortex
Outer, protective layer of kidney
Hilum
Intended area of kidney where blood vessels, ureters enter and exit
The urethral sphincters
Round muscle that opens to allow urination
Renal pelvis
Area of kidney where urine converges from the tubules before entering the ureter
A person drinks a large amount of water and urinary output increases
An example of the urinary system’s ability to maintain homeostasis
Above the waist, towards the back
Where are the kidneys located?
Bowman’s capsule
What C-shaped structure in the nephron surrounds the glomerulus?
Reabsorbed into the blood
During the process in healthy nephrons most of the water, glucose, and vitamins are:
Polyuria
Ms Your In is not ill but drank a large amount of ice tea. You would expect her to have:
Remove waste products from the blood
What does hemodialysis do?
Na & K (Sodium & Potassium)
Two electrolyte levels that are controlled by the kidneys are
Peritubular capillaries
The vessels in the nephron that reabsorb needed substances for the bloodstream are the:
Can lead to kidney damage if untreated
Urinary Tract Infection is:
Glucose, RBC’s, WBC’s
Normal urine does NOT contain
is rich in O2 and full of waste products
Blood entering the kidney via the renal artery:
produce necessary antibodies
The kidneys do all of the following except:
urea, creatinine, uric acid, ammonia
Waste products of the metabolism include:
O2 poor, waste free
The blood in the renal veins is:
urination
Micturition is:
retroperitoneal
The kidneys are located in which area?
filtration
The process of plasma like fluid passing through the glomerulus to Bowman’s capsule is called:
renal artery, glomerulus, tubules, renal pelvis
The pathway of urine formation is:
incontinence
Involuntary urination is known as:
glomerular filtration, tubular reabsorption, tubular secretion
The process of urine formation involves:
control the body’s fluid and electrolyte balance, eliminate waste products, control blood pressure
In producing urine, the kidney is able to:
afferent arterioles
The ______ bring blood directly to the glomerulus
Hemodialysis
This procedure involves removing blood from the body, passing it through a filter, and then returning it to the body
Glomerulus
The location in the nephron where plasma and red cells are separated through filtration is:
Blood Urea Nitrogen
Which of the following is a blood test that evaluates kidney function?
Peritoneal dialysis
Procedure cleans wastes out of the body
Bladder
Primarily acts as a reservoir
Hematuria
Blood in urine
U/A & Specific gravity
Measures composition & density of urine
Dysuria
Painful urination
Polyuria
Frequent urination
Pyuria
Urine containing pus
Urinalysis
Test that examines characteristics of urine
