Study Notes
Blood Vessel Flow
- Blood flow direction: Capillaries to venules to veins
- Celiac trunk: A branch of the descending aorta, supplying the gastric, splenic, and hepatic arteries.
- Hepatic portal system: Carries nutrient-rich blood from digestive organs to the liver for processing.
- Splanchnic circulation: Supplies blood to the stomach, spleen, pancreas, and intestines.
- Blood flow from pulmonary capillaries to coronary arteries: Through the ascending aorta.
- Blood flow through the circle of Willis: Supplied by internal and vertebral arteries; delivers oxygenated blood to the brain.
- Largest oxygen concentration in fetal circulation: Umbilical vein
- Blood vessel type for blood flow towards the heart: Vein
- Vein characteristics: Capacitance vessels, storage vessels, contains valves.
- Blood vessel that drains blood rich in digestive products from the small & first part of the large intestine: Superior mesenteric vein
- Blood vessels that deliver blood to brachiocephalic veins: Subclavian veins
- Blood vessel that takes blood from right axillary vein to right axillary artery (no flow through): Right common carotid artery
- Arterioles function: Primarily contracting and relaxing.
- Pulse: Caused by vibrations of blood vessel walls, reflects heart rate.
Hepatic Portal System
- Hepatic portal system function: Delivers blood rich in digestive end products to the liver for processing.
- Hepatic portal system components: Hepatic sinusoids, portal vein, hepatic vessels.
- Blood vessel that delivers blood to the portal vein: Hepatic sinusoids
- Relationship between hepatic veins and hepatic artery to portal vein: Hepatic veins and hepatic artery do not merge to form the portal vein.
Coronary Arteries & Pathway
- Cardiac catheterization pathway: Catheter is threaded through various blood vessels, bypassing the inferior vena cava.
- Blood vessels not used in cardiac catheterization: Inferior vena cava
Renal Arteries
- Renal arteries originate from: Abdominal aorta
