Reddish brown organ, 4 lobes, receives 25% of resting cardiac output= ?
Hepatic System
Liver:
- Reddish brown organ with 4 lobes
- Receives 25% of resting cardiac output
- Posteriorly, liver is located between T9-L1 at the midline
- Gallbladder primarily stores bile , Base of gallbladder at the tip of the 9th costal margin
Posteriorly, liver is located between = ?
Hepatic System
- Posteriorly, liver is located between T9-L1 at the midline.
Gallbladder primarily stores = ?
Hepatic System
- Gallbladder primarily stores bile.
Bile
- Greenish yellow secretion that is produced in the liver and passed to the gallbladder for concentration, storage, or transport into the first region of the small intestine, the duodenum.
Function
- Aid in the digestion of fats in the duodenum.
Base of gallbladder at the tip of = ?
Hepatic System
Base of gallbladder at the tip of the 9th costal margin.
Arterial blood to the liver = ?
Hepatic System
Arterial blood to the liver=
(a) Hepatic Artery:
- Branch of celiac artery
Carries partially deoxygenated blood from GI, spleen and associated organs to liver = ?
Hepatic System
Portal vein:
- Carries partially deoxygenated blood from GI, spleen and associated organs to liver.
Functions of the liver include = ?
Hepatic System
Liver Functions:
- Metabolism: Carbohydrates, fats, and protein.
- Secretory: Bile acids, bile salts, and pigments.
- Excretory: Bilirubin, drugs, toxins
- Synthesis: Albumin, coagulation factors
- Storage: Vitamins, carbohydrates, etc.
- Detoxification: Toxins, ammonia, etc.
Bilirubin is produced in = ?
Hepatic System
Bilirubin:
- Produced in bone marrow and also in the liver as end product of hemoglobin breakdown.
- Gives feces and urine it’s characteristic color.
- Normal levels: less than 1.5 mg/dl
Bile is
- Required for = ?
- Contains = ?
Hepatic System
Bile:
- Required for digestion of dietary fats and absorption of fats and fat-soluble vitamins from the intestine.
- Bile contains bile salts, water, bilirubin.
The liver produces how much bile daily= ?
Hepatic System
Liver produces 500-600 ml of bile daily.
Jaundice:
- What is it = ?
- Two signs & symptoms = ?
- Etiology = ?
Hepatic System
Jaundice:
- Abnormal high amounts of bilirubin in the blood.
- Bilirubin levels 2-3 mg/dl: Sclera of eye as yellow.
- Bilirubin levels 5-6 mg/dl: changes in skin color
Etiology:
- Imbalance between synthesis and clearance of bilirubin.
- Excessive destruction of erythrocytes.
- Excessive production of bilirubin.
- Obstruction of bile flow
Three examples of skin changes associated with Jaundice = ?
Hepatic System
Skin Changes:
- Jaundice, pallor, and orange or green skin in Caucasians.
- Bruising/ itching
- Spider angiomas: Dilatations of superficial capillaries, increased estrogen levels (liver unable to metabolize and inactivate estrogen).
- Palmar erythema: Warm redness of skin over palms, due to increased estrogen level, and associated with throbbing and tingling.
Pain Patterns:
Referred Pain Location:
- Thoracic spine, T7-T10, midline to the right
- Right upper trapezius and shoulder
Systemic Cause= ?
Hepatic System
Referred Pain Location:
- Thoracic spine, T7-T10, midline to the right
- Right upper trapezius and shoulder
Systemic cause:
- Liver disease (abscess, tumor, cirrhosis, hepatitis).
Primary pain: Right upper quadrant abdominal pain.
Referred Pain Location:
- Right upper trapezius and shoulder
- Right interscapular area(T4 or T5-T8)
- Right subscapular area
Systemic Cause= ?
Hepatic System
Referred Pain Location:
- Right upper trapezius and shoulder
- Right interscapular area(T4 or T5-T8)
- Right subscapular area
Systemic Cause:
- Gallbladder
Primary pain: Right upper quadrant abdominal pain.
Hepatic osteodystrophy = ?
Hepatic Osteodystrophy: Hepatic osteodystrophy(HO) is the generic term defining the group of alterations in bone mineral metabolism:
- Osteomalacia
- Osteoporosis
- Vertebral wedging
- Vertebral crush fractures
- Kyphosis
- Altered CNS function
- Alterted metabolism
- Confusion
- Tremors
- Asterixis
These are examples of = ?
Hepatic System
Neurologic signs and symptomsassociated with liver disfunction:
- Altered CNS function
- Alterted metabolism
- Confusion
- Tremors
- Asterixis: Flapping tremor/ liver flap
Connection between liver disfunction and edema = ?
Hepatic System
Edema due to decreased serum albumin levels.
Bile converted from bilirubin causes brown coloration of stool
Light clay colored stool
Urine color of tea or cola (dark colored urine)
When bile is converted from bilirubin, what can happen to stool = ?
Hepatic System
Bile converted from bilirubin causes brown coloration of stool.
- Light clay colored stool
- Urine color of tea or cola (dark colored urine).
Chronic progressive inflammation of the liver due to reduced blood flow = ?
Hepatic System
Cirrhosis:
- Chronic progressive inflammation of the liver.
- Represents end stage chronic liver disease.
- Reduced blood flow to liver = death of hepatocytes.
- The progressive loss of normal tissue leads to liver tissue being replaced with fibrous and nodular regeneration.
- 12th leading cause of death
Most common causes in US:
- Alcohol abuse
- Hepatitis C
- Toxic reactions to drug
