Blood vessels

profuse the tissues

80

Arteries

-carry oxygen rich blood AWAY from the heart
-thicker walls (esp. tunica media)
-smaller lumen (hollow passageway)
-three types

81

What are the three types of arteries?

1. Elastic- near heart, large
2. Muscular- supply organs, middle sized
3. Arterioles- connect to capillaries, smallest

82

Capillaries

-bring oxygen and nutrients to surrounding tissues, pick up gas/wastes
*good for diffusion
-smallest vessels --> RBCs travel single file

83

Veins

-carry de-oxygenated blood TO the heart
-thicker tunica externa
-larger lumen
-less elastic --> prone to collapse under pressure
-increase in size closer to the heart

84

Venous Return

returning of blood to the heart (usually against gravity)
1. One-way valves- prevent back flow
2. Muscular Pump- skeletal muscles squeeze veins during contraction
3. Respiratory Pump- inhalation increases pressure on veins

85

Varicose Veins

veins no longer straight because valve become incompetent, blood pools

86

Anastomoses

network of interconnected arteries and veins (NOT capillaries) that provide alternate pathway for circulation
-found in joins and GI circulation
