Blood Flow in the Kidneys: Blood enters the kidneys through the renal artery, flows through the glomerulus for filtration, and exits via the renal vein after reabsorption and secretion processes.
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.
Spleen: The spleen filters blood, removes old red blood cells, stores platelets, and plays a key role in the immune response by housing lymphocytes and macrophages.
