What does the term 'intravenous' refer to?

The term 'intravenous' refers specifically to the delivery of substances directly into a vein. This method allows for rapid absorption into the bloodstream, facilitating immediate therapeutic effects. When medications or fluids are administered intravenously, they bypass the digestive system and liver metabolism, enabling a more accurate control of dosage and more immediate effects in patients. This method is commonly used in medical settings for hydration, nutritional support, and the administration of various drugs. Understanding the precise nature of intravenous therapy is crucial in animal science, particularly in veterinary medicine, where swift treatment interventions can significantly impact patient outcomes.
