Published	08/12/2024	{{c1::Kidney}}: cortex and medulla (medullary pyramid → ureter)  Functions: remove waste , regulation BP, electrolyte concentration
Published	08/12/2024	Describe/identify the following structures where they occur: mucosa; lamina propria; submucosa, muscularis, serosa; adventitia, including the sublayer…
Published	08/12/2024	Muscularis mucosae and submucosa unique to {{c1::digestive tube}}
Published	08/12/2024	Explain the concept of dual blood supply as it applies to lung and liver, and name the vessels involved.
Published	08/12/2024	Compare and contrast the layers and sub-layers of blood vessels with that of hollow organs such as the digestive tube

Published	08/12/2024	Layers and sub-layers of blood vessels
Published	08/12/2024	{{c1::Large arteries}} have elastic lamellae to store and release energy during systole and diastole
Published	08/12/2024	{{c1::Medium arteries}}:have 5+ layers of smooth muscle and internal elastic lamina
Published	08/12/2024	{{c1::Arterioles}} have <5 layers of smooth muscle and carry oxygented blood
Published	08/12/2024	{{c1::Capillaries}}: nutrient, waste, gas exchange between blood and tissues
Published	08/12/2024	Types of cappillaries
Published	08/12/2024	{{c1::Post-capillary venules}} are the leakiest part of the blood vascular system (even more leaky than most capillaries)
Published	08/12/2024	{{c1::Medium veins}}: tunica media with ~6 layers of smooth muscle thinner than adventitia
Published	08/12/2024	{{c1::Large veins}}: tunica media more muscle, but not as much as arteries
