Kupffer cells are phagocytes located in the:

A. They have thin walls – Lymphatic vessels have thin walls, similar to veins, which allow for the passage of lymph.
B. They can contract to propel lymph – Lymphatic vessels do have the ability to contract, aided by smooth muscle and valves, which helps propel lymph in the right direction.
C. They transport lymph to the tissues – This statement is incorrect. Lymphatic vessels carry lymph away from the tissues (not to the tissues) and toward lymph nodes and eventually to the bloodstream.
D. They are blind-ended – Lymphatic capillaries are indeed blind-ended, meaning they begin as closed-ended tubes that absorb interstitial fluid from tissues.

A. Inguinal nodes are located in the groin area, not the neck.
B. Subclavian nodes are found near the clavicle (collarbone), closer to the chest, not specifically in the neck.
C. Cervical nodes are the correct answer. These lymph nodes are located in the neck and are responsible for filtering lymph from the head and neck region.
D. Palatine tonsil is located in the oropharynx (back of the throat), not in the neck, although it is part of the lymphatic system.
