Step-by-step explanation:

The secondary lymphatic structures with a complete capsule include the spleen and lymph nodes. The spleen is an encapsulated structure that filters blood, captures pathogens and antigens, and is crucial for antigen presentation. It is often referred to as the 'filter of the blood'.

Lymph nodes are bean-shaped organs encapsulated by a tough layer of connective tissue and are structured into compartments. They play a critical role in filtering lymph and initiating immune responses. In contrast, lymphatic nodules, mucosa-associated lymphoid tissue (MALT), and tonsils do not have a complete capsule. Instead, they consist of clusters of lymphocytes without a surrounding fibrous capsule.
