Which of the following describes internal parasites?

Internal parasites are organisms that inhabit the interior of a host animal, drawing nutrients and resources to survive. They can affect various organs and systems within the host, leading to a range of health issues, including malnutrition, weakness, and other serious medical conditions. Common examples of internal parasites include worms like tapeworms, roundworms, and flukes.

This understanding distinguishes internal parasites from those that live external to the host, such as those found on the skin or in the environment. These external parasites, while harmful, interact with the host in different ways, typically leading to irritation or infection on the surface rather than inside the body.
