Question

lo 2.4. what is the lymphatic system?
a system that helps maintain fluid balance and protect against infections and diseases
a system that helps with sensory perception
a system that transports oxygen and nutrients throughout the body
a system that regulates blood pressure
a system that controls the bodys metabolic processes

Explanation:

The lymphatic system has two main functions. One is to maintain fluid balance by returning excess interstitial fluid to the bloodstream. The other is to protect against infections and diseases as it is a crucial part of the immune system (containing lymph nodes, lymphocytes etc. that fight pathogens).
Sensory perception is mainly related to the nervous system (e.g., sensory neurons). Transporting oxygen and nutrients is the function of the circulatory system (blood in blood vessels). Regulating blood pressure is also related to the circulatory system (e.g., through mechanisms like the renin - angiotensin - aldosterone system). Controlling metabolic processes is more associated with the endocrine system (hormones like insulin, thyroxine etc.).

Answer:

A system that helps maintain fluid balance and protect against infections and diseases
