Starts form the capillaries and consists of collecting venules, venules, small and large veins which function is to collect, store, and deliver blood into the ________
Delivery of blood into the atria is called

Have thinner muscular wall and same as the anterioles, they are innervated by ,________
Venules; sympathetic fibers
Have thin muscle coat and 2/3z of blood volume in systemic circulation us present here
_______ made up of thin folds of tunics intima and prevents retrograd flow of blood, facilitates venous return
Veins; venous valves
Endothelial cells lining the vessels mend the surfcse of existing blood vessels snd generate new vessels
Angiogenesis
