Chapter 26 Urinary

Heart → aorta → renal artery → segmental/lobar arteries → interlobar arteries → arcurate arteries → interlobular (cortical radiate) arteries → afferent arteriole → glomerulus

List the order of blood flow TO the kidneys (heart → glomerulus)

Glomerulus → efferent arteriole → peritubular capillaries → venules → interlobular (cortical radiate) vein → arcuate vein → interlobar vein → renal vein → inferior vena cava → heart

List the order of blood flow FROM kidneys (glomerulus → heart)

Glomerulus → proximal convoluted tube → urinephronous (nephron) → loop of Henle → distal convoluted tube → collecting duct → minor calyx → major calyx → renal pelvis → hilum → ureters

List the order of urine flow from glomerulus → ureter

Nephron

Basic functional unit of the kidney

Collecting duct

Urine collects here before leaving the kidney

Ureter

Connects the kidney to the bladder

Retroperitoneal

The kidneys are located behind the peritoneal membrane meaning they are

Hilum

Where the renal artery/vein enters/exits as well as where ureters enter and pee exits

Transitional epithelium

Tissue in the bladder that allows it to stretch and move

Urethra

The structure where urine leaves the body

Trigone

Triangular area of the bladder that prevents urine backflow into the kidneys and where ureters enter and urethra exits the bladder

Detrusor muscle

Muscle that contracts in the bladder to release urine

Pararenal fat → adipose capsule → peritoneal fat → fibrous capsule

Name the layers of fascia that protect the kidney from superficial to deep

Papilla

Another name for the apex of renal pyramids

Apex

Is the base or apex of the renal pyramid close to the minor calyx of the kidney?
