Liver Unveiled: Navigating the Complexities of the Liver Mindmap
Explore the liver's vital functions through a detailed mind map. Dive into the anatomy, functions, and key processes of this vital organ.
Understand how the liver plays a crucial role in digestion, metabolism, and detoxification. Visualize the different regions of the liver, such as the left and right lobes, and their functions.
Here is a detailed comprehensive mind map of the physiology topic "liver":Central Idea: LiverMain Branches:
- Structure
- Functions
- Blood Supply
- Regulation
- Clinical Correlations
1. Structure
- Gross Anatomy
- Location (right upper quadrant of abdomen)
- Shape (wedge-shaped)
- Size (approximately 3 pounds)
- Microscopic Anatomy
- Hepatocytes (liver cells)
- Sinusoids (blood-filled spaces)
- Space of Disse (space between hepatocytes and sinusoids)
- Bile canaliculi (small channels for bile transport)
- Lobes and Segments
- Right and left lobes
- Four segments (I-IV)
- Metabolism
- Carbohydrate metabolism (glycogen synthesis and breakdown)
- Protein metabolism (amino acid synthesis and breakdown)
- Lipid metabolism (fatty acid synthesis and breakdown)
- Detoxification
- Xenobiotic metabolism (breakdown of foreign substances)
- Biotransformation (conversion of lipophilic to hydrophilic compounds)
- Synthesis
- Albumin synthesis
- Coagulation factor synthesis
- Bile production
- Storage
- Glycogen storage
- Vitamin and mineral storage
3. Blood Supply
- Hepatic Artery
- Oxygen-rich blood supply
- Branches into right and left hepatic arteries
- Portal Vein
- Nutrient-rich blood supply from digestive tract
- Branches into right and left portal veins
- Hepatic Veins
- Drainage of deoxygenated blood into inferior vena cava
4. Regulation
- Hormonal Regulation
- Insulin and glucagon regulation of glycogen metabolism
- Thyroid hormone regulation of metabolism
- Nervous Regulation
- Sympathetic and parasympathetic nervous system regulation of liver function
- Autoregulation
- Liver's ability to regulate its own blood flow and function
5. Clinical Correlations
- Liver Diseases
- Hepatitis (inflammation of the liver)
- Cirrhosis (scarring of the liver)
- Liver cancer (hepatocellular carcinoma)
- Liver Function Tests
- Alanine transaminase (ALT) and aspartate transaminase (AST) levels
- Alkaline phosphatase (ALP) levels
- Bilirubin levels
- Liver Transplantation
- Indications for liver transplantation
- Surgical procedure and post-operative care
