Function/Structure
Urine Formation
Blood Pressure Regulation
Urinary Tract
Little Bit of Everything
100
This organ filters the blood and processes filtrate into tubular fluid, then urine.
What is the Kidney!
100
Urine is this much of the original volume of filtrate
What is <1%
100
These cells sense blood pressure in the afferent arteriole.
What is Granular cells (mechanoreceptors)
100
When observed, this can indicate a urinary tract infection
What is cloudy urine.
100
The male urethra is partitioned into these three sections
What is Prostatic urethra Membranous urethra Spongy urethra
200
reservoir for urine until micturition occurs.
What is the urinary bladder.
200
The movement of substances from the tubular fluid back into the blood
What is tubular reabsorption
200
decreased blood pressure would mean an increase in what?
What is GFR and Urine output
200
These can all lead to discolored urine
What are Food ingestion, bile pigments, blood, and drugs
200
These chemicals enhance urinary output.
What is ADH inhibitors.
300
Storage of urine Excretion of urine Regulation of blood volume Regulation of erythrocyte production Regulation of ion balance/acid-base balance The above are all examples of
The functions of the urinary system.
300
Nephrons form the urine through these three processes
What is filtration, tubular reabsorption, and tubular secretion
300
This is the main mechanism for regulating blood pressure.
What is the RAAS system. BONUS (100): define each part of the RAAS system
300
This is the chemical composition of Urine.
What is 95% water and 5% solutes
300
Secretes K+ and H+ from peritubular capillaries into tubular fluid
What is DCT
400
The functional unit of the Kidney
What is the nephron
400
The movement of substances from the blood within the glomerulus into the capsular space.
What is glomerular filtration
400
This hormone converts angiotensin I to angiotensin II
What is Renin
400
Ureters Urinary bladder Urethra These together make up..
What is the urinary tract.
400
This causes water to move out of the filtrate in the descending limb.
What is osmotic gradient.
500
Given these parts of a nephron: ??1. renal corpuscle ?2. collecting duct ?3. loop of Henle ? 4. distal tubule ?5. proximal tubule ??Arrange the parts in order as fluid flows from the filtration membrane through the nephron.
What is 1,3,5,4,2
500
The movement of substances from the blood into the tubular fluid
What is tubular secretion
500
Explain what happens when extracellular fluid volume is low.
Norepinephrine released by sympathetic nervous system --> epinephrine released by adrenal medulla, Systemic vasoconstriction-->increased blood pressure Constriction of afferent arterioles -->decreased GFR --> increased blood volume and pressure
500
The wall of the ureters is made up of
What is Mucosa, Muscularis, and Adventitia.
500
Explain the process of urine formation starting from the glomerulus.
I'm not typing this all out... I'm sure Rives will go over this with us as a class anyway....
