Study Notes
Blood Vessels
- Arteries carry blood away from the heart
- Arterioles regulate blood vessel diameter
- Capillaries are small blood vessels
- Veins return blood to the heart
- Venules connect veins and capillaries
- Veins have one-way valves
- Veins have thin walls
Blood Pressure
- Blood pressure is measured as systolic and diastolic
- Systolic pressure is the highest pressure during a heartbeat
- Diastolic pressure is the lowest pressure between heartbeats
Systemic Circulation
- Oxygenated blood travels from the heart to body tissues through arteries and capillaries
- Blood vessels carry the oxygenated blood throughout the body
Liver Structure and Function
- The liver is part of the hepatobiliary system
- The liver is a metabolic system
- The liver converts nutrients
- The liver detoxifies substances
- Hepatocytes are the functional cells of the liver
- Kupffer cells are resident macrophages in the liver
