Exudates are fluids that leak out of blood vessels into surrounding tissues, often due to inflammation or injury. They can contain a mix of proteins, cells, and other substances, and are typically classified into different types based on their composition, such as serous, purulent, or fibrinous exudates. These fluids play a crucial role in the body's healing process by delivering nutrients and immune cells to the affected area. However, excessive exudate can lead to complications, such as wound infection or delayed healing, making it important to monitor and manage exudate levels in clinical settings.
