Anatomy of the Kidney and Adrenal Gland Flashcards
Where do adrenal glands lie
Upper pole of the kidney
What is another name for adrenal gland
Suprarenal
Where does the right adrenal gland lie
Behind the liver and inferior vena cava
Where does the left adrenal gland lie
Behind the stomach and pancreas
What are the arteries supplying each gland
Superior adrenal artery
Middle adrenal artery
Inferior adrenal artery
What is the superior adrenal artery a branch of
Inferior phrenic artery
What is the middle adrenal artery a branch of
Abdominal artery
What is the inferior adrenal artery a branch of
Renal artery
What are the adrenal glands drained by
Single vein on each side
Right and left adrenal gland
What does the right adrenal gland directly drain into
Inferior vena cava
What does the left adrenal gland directly drain into
Left renal vein - then joins the inferior vena cava
What is the adrenal gland composed of
Cortex (outer part)
Medulla (inner part)
What does the cortex of the adrenal gland produce
Steroid hormones
Including:
- Cortisol
- Aldosterone
- Testosterone
What does the medulla of the adrenal gland produce
Adrenaline
What are the shape and size of the kidneys
Two bean-shaped kidneys
11cm long
7cm wide
4cm thick
Where do the kidneys lie
Extra-peritoneal structures - lie outside the peritoneum
Retro-peritoneal
Where are the kidneys located
One on either side of the upper lumbar vertebrae
What is each kidney embedded by
Perinephric fat covered by renal fascia covered by perinephric fat
What is on the medial side of the kidney
Renal hilum - where renal vessels, nerves, lymphatics and ureter enter or leave the kidney
What are the right and left arteries branches of
Abdominal aorta
What do the right and left renal veins drain into
Inferior vena cava
What is the internal aspect of the kidney composed of
Cortex
Medulla
Calyces
What is the outer part of the kidneys
Cortex
What is the medulla arranged in
Pyramids
What are the functional units of the kidneys
Nephrons
What is the role of the nephrons
Filter blood
Reabsorb water and solutes
Secrete and excrete waste products as urine
What is located in the cortex
Glomeruli
Glomerular capsules (Bowman’s capsules)
Proximal and distal tubules
Part of the collecting ducts
What is located in the renal pyramids
Nephron loop (of Henle)
Rest of the collecting ducts
From the collecting ducts where does urine travel
Down the pyramids towards the renal papilla to the minor calyx
