Urinary system Flashcards
The middle layer of the kidney which contains the loops of Henle of the Nephrons
Medulla
Water, nitrogenous wastes, glucose, and salts leave the blood during _ filtration
Pressure
The process of removing metabolic wastes from the body
Excretion
As the loop of henle descends deeper into the medial, the surrounding tissue becomes _ in solute concentration
Higher
Active transport of molecules out of the filtrate and back into the blood requires this energy molecule
ATP
_ transport is used to move glucose out of the filtrate and back into the blood in the PCT
active
The _ duct moves urine from the nephrons to the renal pelvis
Collecting
Water that has left the descending loop of henle cannot re-enter in the ascending loop of henle because it is _ to water
Impermeable
The _ can override the urge to urinate
Brain
After pressure filtration has occurred, this substance is present in the proximal convoluted tubule
Filtrate
A hormone, released by the adrenal cortex, which increases Na+ reabsorption and promotes excretion of K+
Aldosterone
_ receptors in the bladder send impulses to spinal cord and brain, indicating that the bladder is full
Stretch
Paired organs which remove carbon dioxide from the blood
Lungs
A large organ which breaks down toxic substances in the blood
Liver
ADH regulates blood pressure by controlling blood _
Volume
RBCs, WBCs, platelets, and plasma _ do not leave the blood during pressure filtration in the glomerulus
Proteins
Paired organs involved in removing toxic substances in the blood
Kidneys
The material passing through the loop of henle is known as _ fluid
Tubular
The loop of _ is where the majority of water present in the filtrate is reabsorbed
Henle
The _ arteriole brings blood to the glomerulus
Afferent
The _ is a tube which leads from the urinary bladder to the outside environment
Urethra
The urethra has both an internal and external _ muscle which prevent urine from leaving the bladder
Sphincter
_’s capsule is where blood is pressure filtered in the first step of urine formation
Bowman’s
A waste produce produced during metabolism which can cause gout if levels become too high
Uric Acid
