Liver Flashcards
Liver pathophysiology
P D S M (ppl drink so much)
Recycling P D S M
P - produce
- A - albumin (makes)
attracts
fluid into vascular system
Drugs,
Binds to calcium
- Bile (bus) - bilirubin (old RBC) to the spleen, convert RBC into bilirubin, back vascular system to liver, then converted into bile,
Bile & cholesterol
LABS
Album low, ^ Bilirubin (jaundice) ^ LDL, decrease HDL
- Coagulate - clotting factors
PT -
PTT -
INR - bleed more
D - detox - in kumpfer cells, etoh, drugs into the
D, J, A,
S - storage - glycogen (stored energy)
M - metabolism - converting (byproduct of protein) ammonia into urea, into renal artery & excreted by kidneys
Cirrhosis pathophysiology (scarosis),
- Cirrhosis of the liver causes destruction of liver cells
- Regeneration of cells leads to fibrous connective tissue & irregular shaped/size lobules to develop
- Leads to obstruction blood flow & causes compression of the portal & hepatic veins.
- The disruption of blood flow causes increased pressure in the portal system 5. To decrease the pressure, collateral circulation new channels are developed predominately oesophagus, anterior abdo wall, parietal peritoneum & rectum.
- This allows the blood to travel in different paths to reduce the pressure.
- Varicosities develop where systemic & collateral circulation communicate ( might rupture).

Pathophysiology of portal hypertension
C
Explain what Cirrhosis of the Liver is
Chronic disease that causes cell destruction & fibrosis (scaring). Scaring alters liver structure & vasculature, impairing blood & lymph flow, resulting in hepatic insufficiency & portal hypertension.
COMPLICATIONS
Hyponatremia, water retention, bleeding oesophageal varices,. Coagulopathy, spontaneous bacterial peritoneal, & hepatic encephalopathy
