Fluid exudates are fluids that leak out of blood vessels into surrounding tissues, often due to inflammation or injury. They contain proteins, cells, and other substances that can help the body heal. Common causes of fluid exudates include infections, injuries, and conditions like arthritis or cancer. These fluids can be classified into different types based on their composition. For example, serous exudates are clear and watery, while purulent exudates are thick and contain pus, indicating infection. Proper assessment of fluid exudates is important for diagnosing underlying health issues and determining appropriate treatment.
