X A&P - Chp 15 - blood vessels and circulation Flashcards
Angio
Blood vessels
phl (phlebotomy)
vein
Largets Artery
Aorta
smallest arteries
cappilaries
largest vein
Vena Cava
Arteries
muscular
veins
have valves
Pulmonary Circuit
- pulmonary artery and branches
- capillaries in lungs
- pulmonary veins
Systemic Circuit
- Aorta
- Systemic Capillaries
- Systemic veins
Veins, capillaries, arteries all lined with
Endothelium
Parts of the Aorta (largest artery)
receives blood from Left Ventricle
1) ascending aorta
2) aortic arch
3) thoracic aorta
4) abdominal aorta
Branches of ascending Aorta and Aortic Arch
1) Brachiocephalic artery
2) L common carotid artery
3) L subclavian artery
Branches of Thoracic Aorta
branch to chest wall, esophagus, bronchi, intercostal artieries
Branches of Abdominal Aorta
- Celiac Trunk
.L gastric artery -stomach
.Splenic artery - spleen
.Hepatic artery - liver - Superior mesenteric artery (lg intestine)
- Inferior mesenteric artery (sm intestine)
Phrenic Arteries feed….
the Diaphragm
Arteries to Pelvis and Leg
Internal Iliac, External Illiac, Popliteal
Arteries to Arm and Head
- Internal carotid
- External carotid (femoral)
- Subclavian (vertebral, axillary)
- Brachial (radial and ulnar)
Anastomes (can bypass capillary beds)
- circle of willis (center of brain)
- superficial palmar arch (top of hand, not palm)
Jugular drains blood from…..
head
Superior vena cava drains
head, neck, upper extremeties
Inferior vena cava drains
- R, L veins from paired parts, organs
- unpaired veins from spleen, digestive tract
Hepatic Portal System
carroes blood from abdominal organs to liver
(superior mesenteric vein/splenic vein/gastric, pancreatic, inferior mesenteric veins /Sinusoids
What ensures that anything you eat, does not hit the blood stream until passing through the liver?
Hepatic Portal System
Process of the Hepatic Portal System
Hepatic First Pass Effect
Ascites
fluid that builds up from back pressure in veins due to damaged liver
Bad for Liver
- ETOH (alcohol, liquor)
- Tylenol
Where is clotting factor made?
In the liver (so if you have a damaged liver, your body won’t produce as much clotting factor)
Varicosity
outpouching of vein. Varicose veins
Interstitual Fluid becomes
lymph
