Comparative Anatomy
Circulatory System
,Circulatory System
The circulatory system is the continuous system of tubes through
which the blood is pumped around the body. It supplies the tissues
with their nutritional requirements and removes waste products.
, Circulatory System….
• Heart
• Modified blood vessel
• Aortic arches- within
pharyngeal arches
• Arteries
• Carries blood away from
heart
• Muscular, elastic fibrous
walls
• Regulates blood pressure
• Terminate in capillary bed
• Veins
• Carry blood toward heart
, Pericardium: The pericardium is a tough fibroelastic sac which
covers the heart from all sides except at the cardiac root
• Fibrous pericardium (outer)
• Serous pericardium (inner)
➢Parietal pericardium
➢Visceral pericardium: lying on
epicardium
