L20 - Abdominopelvic Viscera Flashcards
What kind of organ is the spleen?
lymphatic organ
Spleen: functions (2)
- filtration of red blood cells to remove old, larger and deformed cells
- prevention of infection
Surfaces of the spleen
- posterior: diaphragmatic areas
- superior = gastric area
- anterior = colic area
- inferior = renal area
blood supply to spleen
splenic artery
hilum of the spleen
- medial concave area of spleen
- vascular attachment site
the spleen is intraperitoneal which mean…
its lined on all sides by peritoneum
what kind of organs are the kidneys?
retroperitoneal organs
Kidneys: functions (7)
- urine production
- regulation of blood ionic composition
- regulation of blood pH
- regulation og blood volume and blood pressure
- production of hormones
- regulation of blood glucose
- excretion of wastes and foreign substances
which kidney sits lower?
right is lower than left
protextive coverings of the kidney
- PERIrenal fat
- renal capsule
- renal fascia
- PARArenal fat
blood supply to kidneys
abdominal aort –> renal artery
venous drainage of kindeys
renal veins –> inferior vena cava
right renal artery is ___ than the left renal artery
longer
right renal vein is _ than the left renal vein
shorter
hilum of th ekindey
- concave part of thre kidney
- sits medially
3 main structures of the kidney hilum
- renal artery
- renal vein
- ureter
2 main components of the kidney
- cortex
- medulla
cortec of the kindey
- outer component
- main filtering area
medulla of the kidney
- main colums and tubes
- beginning of urine production
internal anatomy of kidneys
- renal pyramid
- renal pailla
- minor calyx (calyces)
- renal pelvis
- major calyx (calyces)
- ureter
pathway of urine 1-6
- renal pyramid
- renal papilla
- minor calyx
- major calyx
- renal pelvis
- ureter
adrenal glands (aka suprarenal glands)
- endocrine organs (produces hormones)
- retroperitoneal organs
what hormones do the arenal glands produce?
- adrenaline
- cortisol
- aldosterone
3 inner layers of cortex
- zona glomerulosa
- zona fasciculata
- zona reticularis
blood supply to adrenal glands
- superior surparenal arteries (extends from inferior phrenic artery)
- middle suprarenal artery (extends directly from abdominal aorta)
- inferior suprarenal artery (from renal artery)
what is deep to cortext?
medulla
venous drainage of adrenal glands
- right suprarenal vein: drains directly into IVC on right hand side (direct drainage)
- left suprarenal vein: drains left renal vein and then into IVC (indirect drainage)
- “asymmetrical drainage”
Branches off of the abdominal aorta
- middle suprarenal artery
- right renal artery (L1)
- celiac trunk (T12)
- left renal artery (T12)
- superior mesenteric artery (L1)
- inferior mesenteric artery (L3)
