NUR 283 - Chapter 10: Blood and the Circulatory System Disorders
Circulatory System consists of the - correct answer cardiovascular
system and lymphatic system
Anatomy of major arteries picture - correct answer
Arteries of major veins - correct answer
Blood circulates through the body and functions to - correct answer •
Transport oxygen and nutrients to all tissues
• Remove waste products of cellular metabolism
• Play a critical role in the body's defenses/immune system, and serve in
maintaining body homeostasis
Arteries - arterioles - correct answer transport blood away from the heart
Arterioles - correct answer small vessels that receive blood from the
arteries
,ØSmalller branches of arteries that control the amount of blood flowing
into the capillaries in specific areas through the degree of contraction of
smooth muscle in the vessel walls (vasoconstriction or dilation)
Veins - venules - correct answer carry blood toward the heart
Venules - correct answer small vessels that gather blood from the
capillaries into the veins
conduct blood from the capillary beds toward the heat
Capillaries - correct answer Microscopic vessel through which
exchanges take place between the blood and cells of the body
Very small vessels organized in numerous networks that form the
Microcirculation within tissues
systemic circulation - correct answer The branch of the circulatory
system that supplies all body organs and then returns oxygen-poor blood
to the right atrium via the veins.
Exchange of gases, nutrients, and wastes between the blood and cells
throughout the body
, Pulmonary circulation - correct answer flow of blood from the heart to
the lungs and back to the heart
Gas exchange of oxygen and carbon dioxide in the lungs
The walls of the arteries and veins are made up of - correct answer 3
layers
1) tunica intima
2) tunica media
3) tunica adventitia
Tunica intima - correct answer the innermost layer of a blood vessel,
composed of a single layer of squamous epithelial cells over a sheet of
connective tissue; its smooth, frictionless surface allows blood to flow
smoothly through the vessel
Tunica media - correct answer The middle and thickest layer of tissue of
a blood vessel wall, composed of elastic tissue and smooth muscle cells

system and lymphatic system
