Edema
Edema is the abnormal accumulation of fluid in the interstitium or body cavities due to an imbalance in fluid homeostasis.
Types of Edema
Types include pitting edema, caused by protein deficiency, increased hydrostatic pressure, increased capillary permeability, or fluid retention; and non-pitting edema, caused by lymphatic obstruction or hypothyroidism (myxedema).
Edema Pathogenesis
Pathogenesis involves decreased plasma oncotic pressure, increased capillary hydrostatic pressure, lymphatic obstruction,

Metabolic Pathways: Urea Cycle, Beta-Oxidation, and TCA Cycle
Role of the Urea Cycle in Nitrogen Removal
The urea cycle is a series of biochemical reactions that removes excess nitrogen from the body by converting it into urea. Urea is then excreted in the urine.
How the Urea Cycle Works
- Ammonia is created from amino acids.
- The liver’s mitochondria convert ammonia into urea.
- Urea enters the bloodstream.
- The kidneys filter urea out of the blood.
- Urea is removed from the body in urine.
Why the Urea Cycle is Important
- The urea cycle is the main way the body removes excess
Key Eukaryotic Organelles: Structure and Roles
Centrosome: Structure and Functions
The centrosome is a dense material, often referred to as the centrosphere, with few radial microtubules. Each centriole consists of nine groups of microtubule triplets arranged as a cylinder, held together by proteins. These triplets remain united by proteins.
Functions:
- Microtubule organizing centers.
- Involved in the formation of cilia and flagella.
- Forms the mitotic spindle during cell division.
- Contributes to the structure of the cytoskeleton.
Ribosomes: Essential
