What is the main function of the lymphatic system?

The primary function of the lymphatic system is to facilitate immune responses, making this the correct choice. The lymphatic system plays a crucial role in the body’s defense mechanisms. It works by transporting lymph, which is a fluid that contains infection-fighting white blood cells known as lymphocytes. These lymphocytes are essential for identifying and attacking pathogens such as bacteria and viruses.

Additionally, the lymphatic system aids in the drainage of interstitial fluid, which helps prevent edema and maintains fluid balance within the body. It also plays a vital part in the absorption of fats and fat-soluble vitamins from the digestive system through specialized lymphatic vessels known as lacteals. However, the integral component of the lymphatic system is its function in immune surveillance and response, which enables the body to recognize and respond to infections effectively.

The other options, while related to bodily functions, do not adequately capture the primary role of the lymphatic system. Transporting oxygen is the main function of the circulatory system, particularly by red blood cells. Transporting nutrients is also primarily the role of the circulatory system, where nutrients are delivered from the digestive tract to cells throughout the body. Removing waste, although a function of several systems including the circulatory and excretory
