Discover how the body’s vascular glands, especially the spleen, work without ducts to influence blood and immune function.
This section explains a modified form of secretion found in vascular glands, including the spleen and thymus, and how these organs relate to lymphatic tissue. It details the spleen’s position, its fibrous capsule, the splenic pulp, and the Malpighian corpuscles that resemble lymph gland tissue. You’ll see how blood moves through the pulp and how the organ swells with blood during digestion, with structure and function tied closely to its unique, ductless nature.
Learn how the spleen’s framework and pulp are organized, the role of trabeculae, and how arteries, capillaries, and veins interact within the organ. The description also covers how the spleen resembles lymphatic glands in structure and function, and how its cells can behave like lymph corpuscles or red blood cells, linking anatomy to physiology in a clear, practical way.
- What makes vascular glands distinct from true secretory glands, and what that means for their function.
- The spleen’s location, capsule, trabeculae, pulp, and the Malpighian corpuscles that mirror lymph tissue.
- How blood traverses the spleen’s pulp and how its vessels adapt during engorgement.
- Connections between structure and function in the immune-like roles of these organs.
Ideal for readers of physiology and students seeking a clear, practical view of how the body’s vascular glands operate.
