Urinary System Flashcards

Flashcards from class

Blood

The urinary system consists of two kidneys that filter the

retroperitoneally

The kidneys are positioned

renal pelvis

The major and minor calyces are located in the

renal sinus

The blood vessels, nerves, lymphatic vessels, and the ureter enter the kidney at the on medial

nephrons

The functional units of the kidney are the

renal cortex

The outer region of the kidney is the

renal medulla

The inner region of the kidney is the

erythropoietin

The kidneys help control the rate of red blood cell formation by secreting

renin

The kidneys help regulate blood pressure by secreting

abdominal aorta

What vessel gives rise to renal arteries leading to the kidneys

inferior vena cava

Venous blood is returned through a series of vessels that join what major vessel leading back to the heart

renal corpuscle

What is the filtering portion of the nephron called?

collecting duct

The distal convoluted tubles join to become a

juxtaglomerular apparatus

The macula densa together with the juxtaglomerular cells make up the

glomerular filtration

When the fluid portion of the blood (plasma) is filter this is called

hydrostatic pressure

The main force responsible for moving substances by filtration through the glomerular capillary wall is

decrease

When the afferent arteriole constricts in response to sympathetic stimulation, filtration pressure and filtration rate will increase or decrease?

increase

When the efferent arteriole constricts, filtration pressure increases, does the rate of filtration increase or decrease?

sodium

The renin-angiotensin system, which regulates what type of excretion

tubular reabsorption

When solutes are moved from the fluid back to the blood is called

tubular secretion

Transporting certain substances from the plasma into the renal tubule is called

95%

Urine is made up of how much water?

detrusor

What muscle will prevent the bladder from emptying until the pressure is increased to a certain level?

micturation reflex

Urine leaves the bladder by a

urethra

What conveys urine from the bladder to outside the body?
