Fenestrated Capillary: Fenestrated capillaries have pores in their walls that allow for rapid exchange of water and small solutes, commonly found in kidneys, intestines, and endocrine glands.
Thoracic Abdominal Arteries Chart: This chart maps the major arteries branching from the thoracic and abdominal aorta, such as intercostal, celiac, mesenteric, and renal arteries that supply the torso and organs.
Capillary Bed: Capillary beds are networks of microscopic vessels where exchange of oxygen, nutrients, and waste occurs between blood and surrounding tissues, regulated by precapillary sphincters that control blood flow.
Large Medium Vein Venule: Venous return involves small venules merging into medium and large veins; these vessels have thinner walls than arteries and contain valves to prevent backflow.
