Study Notes

Blood Vessel Structure and Function

Arteries carry blood away from the heart
Arterioles and capillaries branch from arteries
Arterial walls adjust blood flow
Veins return blood to the heart
Venules and capillaries connect to veins
Veins have one-way valves
Veins have thin walls

Blood Pressure

Systolic pressure: peak pressure during heart contraction
Diastolic pressure: pressure when the heart relaxes
Blood pressure is vital for circulation and oxygen delivery to tissues

Systemic Circulation

Oxygenated blood travels from the left ventricle to tissues via arteries and capillaries
Blood delivers oxygen to cells and removes waste products

Liver Structure and Function

Liver's metabolic system processes nutrients
Liver converts nutrients into usable forms
Liver detoxifies harmful substances
Hepatocytes are the primary liver cells
Kupffer cells are resident macrophages in the liver, a vital part of the immune system that helps remove waste products.
