hbs unit 3
Terms in this set (44)
filters waste ad disposes of it.
the indentation allows for the renal artery/ vein, and ureters to enter the kidney
pair of tubes that carry urine from the kidneys to the urinary bladder
10-12 inches long
sac like hollow organ used for the storage of urine
tube that transports urine to outside of the body
Renal artery to the kidney through the nephron out the renal pelvis down the ureters into the bladder then out the urethra.
What are the main functions of the urinary system?
to filter the body's waste and remove it from the body
What organs or structures in the body (other than the urinary system) help you maintain a water balance? Explain.
large intestines and sweat glands
How does the urinary system differ in males and females?
males have a longer urethra than females and they also have prostates which affect their ability to urinate as they get older.
blood vessels into kidney
blood vessels out of kidney
parts of the nephron
glomerulus,efferent and afferent arteriole, bowman's capsule, distal convoluted tubule, descending loop of henle, ascending loop of henele, proximal convoluted tubule, collecting duct.
where are nephrons located
in the medulla pyramid
How will other body systems be affected if the kidneys begin to shut down?
there would be nothing filtering out the waste products of the body so eventually, the toxins would build up and the body will shut down.
Suggest reasons why we can live with one kidney, but we are born with two.
if only one kidney is present it can do the job of both, but we have two so that one is not overworked.
blood flow through nephron
in through the renal artery, it is filtrated in the bowman's capsule, forced into the tubule, through the loop of henle, through the distal convoluted tubule, and out the renal veins
urine flow through nephron
in through the renal artery, it is filtrated in the bowmans capsule, forced into the tubule, through the loop of henle, through the distal convoluted tubule, down the collecting duct (here the blood becomes urine) then it exits the pyramid into the calicies, to the renal pelvis, through the ureter to the bladder then its removed through the urethera
occurs in the bowman's capsule/ glomerulus
here everything except blood cells are diffused into the bowmans
occurs in the distal convoluted tubule
here ions move back into the blood/ tissue
occurs in the proximal convoluted tubule, the descending, and collecting duct
here water and ions are reabsorbed into the blood/ and body
What is the purpose of reabsorption in the nephron?
reabsorbtion allows the body to take back any materials needed that were previously filtered out
In what direction are substances moving during the process of secretion?
they are secreted into the collecting ducts. This happens so the body can get rid of any unwanted ions
Explain the role of the digestive system, the respiratory system and the urinary system in the removal of waste.
the urinary system removes liquid waste from the body, the respatory system removes gasous waste from the body
Explain how both the digestive system and the urinary system work to conserve water in the human body.
the digestive and urinary system both reabsorb any needed water back into the body
This hormone causes the body to reabsorb water
Alcohol in the kidney
Alcohol inhibits (blocks) reabsorbtion of water whch cause sthe body to become dehydrated and causes person to urinate alot
This is implemented when the body is dehydrated. It opens up the pores in the collecing duct which causes ions to rush into the body and this is followed by water reabsorbtion
Created in the hypothalamus
secreated from the pituitary gland
created in the adrenal gland
secreated from the adrenal gland
what disorders do urinalysis detect
any disorders reguarding any problems with the kidney and body's filtration system
Ex: UTI, kidney disease, and diabetes
yellow, clear, neutral pH, specific gravity of 1.000, no proteins, no glucose, no ketones, and no blood cells of any kind.
Urinary Tract Infection
Urine: high pH, Darker in color, cloudy, and white blood cells are present
Urine: high ketone levels, high pH, and high glucose levels
Increased urine, and dehydration
Urine: higher specific gravity, high glucose
Patient: Female, pregnant, and fatigued
Urine: red bloodcells, dark in color, turbid (not clear), and protein levels
the body is shutting down and toxin levels are building up
Urine: Proteins are present, and specific gravity is elevated
The body is overwhelmed
why should urine be free of blood cells?
the nephron's job is to filter all waste products out of the blood, so blood would be a sign that there is a problem with filtration
observe the color and clarity of urine
observe urine samples for blood cells
uses test strips to monitor urine's pH, Specific gravity, Proteins, Glucose, Ketones
