|---|---|---|---|---|---|
| arteries | carry blood away from the heart
🗑
|
||||
| veins | return blood to the heart
🗑
|
||||
| capillaries | connect the smallest arteries (arterioles) to the smallest veins (venules)
🗑
|
||||
| tunica intima | inner layer, helps prevent blood clots, produces chemicals that cause the blood vessels to dilate or constrict, lines all blood vessels
🗑
|
||||
| tunica media | middle layer, allows blood vessels to change diameter
🗑
|
||||
| tunica externa | outer layer, supports and protects blood vessels
🗑
|
||||
| conducting arteries (elastic arteries) | closest to the heart, greatest ability to expand and recoil
🗑
|
||||
| distributing arteries | deliver blood to specific organs
🗑
|
||||
| aterioles | smallest arteries, dilate or constrict to maintain blood pressure
🗑
|
||||
| Venules | smallest veins, collect blood from capillaries
🗑
|
||||
| categories of veins | venules, medium sized, and large veins
🗑
|
||||
| capillaries | hormones are transferred between blood and tissue, have thin walls, only in endothelium and basement membrane
🗑
|
||||
| capillaries are organized into networks called | capillary beds
🗑
|
||||
| Filtration occurs | close to the arterial side of the capillary bed
🗑
|
||||
| high pressure in capillaries | pushes plasma and dissolve nutrients through capillary wall and into surround fluid
🗑
|
||||
| pulmonary circulation function | to bring deoxygenated blood to the alveoli for gas exchange
🗑
|
||||
| pulmonary circulation blood flow | right ventr-pulmonary arteries-lobar arteries-capillary bed-lobar veins-pulmonary vein-left artium
🗑
|
||||
| ascending aorta | right and left coronary arteries branch off to supply blood to myocardium
🗑
|
||||
| abdominal aorta | branches into the right and left common illiac arteries, which supply blood to the lower pelvis and the legs
🗑
|
||||
| aortic arch | branches into three major arteries, brachiocephalic, common carotid, and left subclavian
🗑
|
||||
| superior and inferior mesenteric arteries | supply blood to the small and large intestines
🗑
|
||||
| abdominal aorta and its branches | supply blood to the abdomen and lower extremities and liver
🗑
|
||||
| common carotid arteries | provide most of the brains blood supply
🗑
|
||||
| superior vena cava | receives blood from above the heart
🗑
|
||||
| inferior vena cava | receives blood from below the level of the heart
🗑
|
||||
| factors affecting blood pressure | cardiac output, blood volume, resistance
🗑
|
||||
| peripheral resistance | resistance to flow results from friction of blood against walls of vessels
🗑
|
||||
| amount of friction depends upon | blood viscosity and vessel diameter
🗑
|
||||
| blood viscosity | typically stable
🗑
|
||||
| vessel diameter | adjusting diameter of the vessels is the body's chief way of controlling peripheral resistance
🗑
|
||||
| blood velocity | diameter of vessel affects how fast blood flows
🗑
|
||||
| greater the diameter of vessel | faster it flows
🗑
|
||||
| blood flows slowest in capillaries due to | cross-sectional area and narrow diameter
🗑
|
||||
| neural regulation of blood pressure | medulla sends impulses via autonomic nervous system to alter blood vessel diameter and therefore blood pressure
🗑
