Urinary System Final
Question | Answer |
---|---|
This system maintains the volumbue and composition of body fluids within normal limits | Urinary System |
What structure envelops the kidneys? | renal capsule |
Exterior to the renal capsule is what? | Adipose tissue |
Outermost layer of the kidney | Renal Cortex |
Contains renal pyramids | Renal Medulla |
Medial to the renal medulla and is continuous with the ureter | renal pelvis |
Directs urine from renal papilla to renal pelvis | Calyces |
Carries urine from kidneys to bladder | ureter |
Functional unit of the kidneys, join to collecting ducts | Nephrons |
Structure extends to to renal papilla of pyramid | Collecting ducts |
Renal Corpuscle (glomerulus) contains what fluid? | Blood |
The glomerular capsule AKA Bowmans capsule contains what fluid? | Urine |
The renal tubual contains what? | urine |
This structure contains arterial capillaries | Glomerulus |
This structure is known as the "collecting cup" for unrine | Glomerular Capsule |
This structure extends in and out of the medulla to the proximal convoluted tubual to nephron loop to distal convoluted tubual and unites with collecting duct | Renal tubual |
The collecting ducts begins__________ and ends_________. | cortex pyramis/papilla |
Brings blood to the kidneys | Renal artery |
Bring blood to pyramids and to nephron | Interlobar arteries |
drain peritubular capillaries | INterlobular Veins |
Drain interlobular veins | Interlobar veins |
Cluster of cells that help modify BP | Juxtaglomerular apparatus |
Hormone secreted by kidney that increases BP by constricting arterioles, conserving water and stimulating water intake to increase BP | Renin |
Hormone secreted by the kidney that stimulates RBC formation when O2 levels fall below nml. | Erythroprotein |
These regulate solute concentration and water concentration in blood | nephrons |
Remove metabolic wastes and excess substances from blood | nephrons |
Water and solutes move from blood and into nephron to form filtrate( beginging of urine) | Glomerular filtration |
When usful substances move from urine to blood | Tubular reabsorption |
When water is removed from urine filtrate and returns to blood (last step) | Water reabsorption |
Do blood cells enter filtrate under normal conditions? | NO |
This uses nutrients and releases waste into the blood | Cellular metabolism |
Solvent of body where chemical reactions occur | Water |
Water balance is regulated by the "thirst center" AKA | hypothalus |
Substances that create ionswhen dissolved in water and conduct electricity | Electrolytes |
This controls whether more or less water than normal is absorbed | ADH |
Waste product of Nucleic acid excess is excreted in urine | Uric Acid |
Waste product of muscle metabolism excreted in urine | Creatinine |
What are the 3 layers of the ureter | OUter fibrous layer, middle layer( smooth muscle that moves urine by peristalsis), Inner layer, mucous membrane for lubrication |
Which layer forms a flap to prevent urine from flowing back into the bladder | Innner layer |
Another word for urination | Micturition |
How many mL can the bladder hold? | 1000 mL |
At how many mL do you feel the urge to urinate? | About 200- 400ml |
INnermost layer of the Bladder wall, w/ transitional epithelium | Mucosa |
Layer of bladder wall that contains blood vessels and nerves | submucosa |
3rd layer of bladder wall that contracts to expel urine and also forms the internal urethral sphinctor | Detrusor muscle |
Smooth muscle is volentary or involentary? | involentary |
Outermost fibrous connective tissue of the bladder wall | Parietal Peritoneum |
Urine is slightly acidic or basic? | Acidic |
What is the Ph level of urine? | 6 |
