Which system is responsible for protecting the body from disease and toxins?

The lymphatic/immune system is specifically designed to defend the body against disease and toxins. This system includes a network of lymph nodes, vessels, and organs such as the spleen and thymus, which work together to identify and eliminate pathogens, such as bacteria and viruses, as well as foreign substances that may harm the body.

It plays a key role in producing and transporting lymph, a fluid that contains immune cells crucial for initiating an immune response when the body encounters harmful agents. This system also has a memory function, allowing the body to respond more effectively to pathogens the next time they are encountered. Furthermore, the lymphatic/immune system is essential for filtering out and removing cellular waste and toxins, helping to maintain overall health and wellbeing.

In contrast, the nervous system is primarily responsible for transmitting signals between different parts of the body and managing responses to environmental stimuli. The endocrine system regulates body functions through hormones, while the respiratory system facilitates gas exchange, bringing in oxygen and expelling carbon dioxide, but does not directly play a role in immune defense.
