Renal System for RC

Kidneys and associated external structures Kidneys, renal capsule, renal artery, renal vein, renal hilum, ureters, urinary bladder, urethra
two bean shaped structures located in the back of the abdominal cavity Kidneys
Tissue that covers the kidney renal capsule
vessel that carries blood into the kidney renal artery
vessel that takes blood away from the kidney renal vein
Indentation where the renal artery and renal vein enter the kidney renal hilum
structure that transports urine from the kidney to the urinary bladder ureters
structure that serves as a reservoir for urine urinary bladder
structure that extends inferiorly from the urinary bladder urethra
The major internal parts of the kidney renal cortex, medulla, calices, renal pelvis, renal papillae
1/3 inside the kidney represents the renal cortex
the middle 2/3 inside the kidney represent the medulla
internal structure composed of the major calyx and the minor calyx renal pelvis
components of renal pelvis major calyx and minor calyx
aka papillary ducts renal papillae
functional unit of the kidney nephron
two types of nephrons juxtamedullary and cortical
components of the nephron glomerulus, proximal tubule, loop of Henle, distal tubule, collecting duct, afferent arteriole, efferent arteriole, Bowman's capsule, renal corpuscule
network of renal capillaries, aka filtering structure glomerulus
vessel that takes unfiltered blood to the glomerulus afferent arteriole
vessel that takes filtered blood away from the glomerulus efferent arteriole
structure that contains the glomerulus Bowman's capsule
glomerular capillary blood pressure + fluid pressure in Bowman's capsule + Osmotic force = net filtration pressure
what is the glomerular capillary blood pressure level? +55 mmHg
what is the fluid pressure in Bowman's capsule? -15 mmHg
What is the osmotic force (caused by protein concentration difference)? -30 mmHg
what is the net filtration pressure level? +10 mmHg
three steps in urine formation glomerular filtration, tubular reabsorption, and tubular secretion
process by which filtrates, mainly electrolytes such as Na+, K+, and Cl- move from BLOOD to URINE as a result of pressure difference in the glomerulus is called: glomerular filtration
process by which filtrates such as water, sodium, glucose move back from URINE in the proximal tubule TO BLOOD is called tubular reabsorption
process occurring between peritubular capillaries and renal tubules by which various substances, such as H+ and K+ are transported from BLOOD to URINE is called tubular secretion
hormone that prevents diuresis, thus helps retain water in the body is called: ADH - Anti-diuretic hormone
if atrial blood volume or pressure increases, then what must happen to ADH? ADH must decrease to stimulate urination
in case of dehydration, what should happen to ADH? ADH should increase for body to retain fluid
electrolytes that can generate acid-base disturbances K+, Na+, Cl-
an increase in K+, Na+, Cl-, or H+ will cause blood pH level to decrease
an decrease in K+, Na+, Cl-, or H+ will cause blood pH to increase
the renal system is able to excrete H+ when: blood pH is low
the renal system is able to reabsorb HCO3- when: blood pH is low
a leak will occur in tissue spaces if systemic capillary pressure exceed: 17 mmHg
congenital disorders, infections, obstructive disorders, inflammation and immune response, neoplasms are examples of: common causes of renal disorders
classification of renal conditions are: pre-renal, renal, and post-renal
abnormalities that impair blood flow TO the kidney describe: pre-renal conditions
abnormalities that impair blood flow WITHIN the kidney describe: renal conditions
urethral or bladder outlet obstructions, such as calculi, tumors, prostatic hypertrophy describe: post renal conditions
