tunica interna

diffusion of molecules

tunica media

pressure and size of lumen

tunica externa

outer blood vessels in large

elastic art

conducting art (help propel blood) pulm trunk

musc arteries

distributing arteries thin extrna thick media

arteioles

resistance vessels, manage flow into capillaries thin tunic media

metarteriole

term end of arteriole goes into capillary

capillaries

smalest blood vessel,network of branched connected EXCHANGE OF O2 CO2

Contin cap

most common water and small solutes

fenstrated cap

rapid exchange of water and small solutes

sinusoidal cap

large diffusion molecules like proteins

Venules

group of capillaries carry blood back to heart

anastomosis

joining of two blood vessels arterial or atriovenous

Arterial anastomosis

two or more arteries supply blood to one capillary bed

atriovenous anastomosis

straight through arteriole to venule

portal system

blood flow to one cap system to another before going to heart

subclavian veins

place of deposit for lymphatic drainage

direct

cell to cell

paracrine

local within tissue

hypothalamus

secretes regulatory hormones which go to anterior pituitary through hypopophseal portal system

pituitary gland

in sella turnica anter and post

infundibulum

connect the pituitary gland to hypothalamus

Ant pituitary

ACTH, TSH, GH stimulates other glands plus PRL, FSH, and LH sex secretion traits

Post pituitary

ADH ( no peeing) and oxytocin (milk release uturine contract)

Thyroid

T3 T4 (energy and metab) and calcitonin (decrease calcium lev)

parathyroid gland

parathyroid hormone (increase calcium lev)

Adrenal cortex

cells peripheral, aidoosterone (increase sodium decrease potas) cortisol (anti inflam plus increase glycogen)

Adrenal medulla

epiinephrine + norepinephrine (increase card activity sugar breakdown)

Pancreas

exo and endo glucagen (alpha) and insulun (beta)
