To determine the components of a lymph node, we need to consider the structure and functions of lymph nodes in the lymphatic system.

Components of a Lymph Node

1. Capsule: This is the outer layer of connective tissue that surrounds the lymph node, providing protection and structural support.

2. Lymphocytes: These are a type of white blood cell found within the lymph nodes. Lymphocytes include T cells and B cells, which play crucial roles in the immune response.

3. Macrophages: These are another type of immune cell present in lymph nodes that help in the process of phagocytosis, engulfing and digesting pathogens and debris.

4. Venous Sinuses: These are spaces within the lymph node that allow the flow of lymph fluid and the movement of immune cells. However, they are more prominent in the spleen and not a classic component of lymph nodes.

5. Red Pulp: This term is typically associated with the spleen, not lymph nodes, as it refers to the area of the spleen involved in filtering blood and recycling iron from hemoglobin.

Summary of Answers

• Capsule: ✔️
• Lymphocytes: ✔️
• Macrophages: ✔️
• Venous Sinuses: ✔️ (but primarily recognized in the spleen context)
• Red Pulp: ❌ (not a component of lymph nodes)

Therefore, the correct selections for components of a lymph node are Macrophages, Capsule, and Lymphocytes. Venous sinuses can be associated but are not definitive components, while red pulp does not apply.
