RABBIT CIRCULATORY SYSTEM Flashcards
Circulatory system Function
Transport of nutrients, gases, hormones and metabolic wastes
Highly branched, organized network of vessels that spreads throughout the entire organism
Circulatory system
Circulatory system pathway
Heart → Arteries → Organs → Veins → Heart
tend to be paired, especially when the organs the supply or drain are paired
Arteries and veins
A _________ often undergoes several name changes along its length as it passes through different body regions.
continuous vessel
HOMOLOGOUS BLOOD VESSELS IN RABBITS AND HUMANS
RABBIT VESSEL NAME
Cranial mesenteric artery and vein
Caudal mesenteric artery and vein
Cranial vena cavae
Caudal vena cava
HUMAN VESSEL NAME
Superior mesenteric artery and vein
Inferior mesenteric artery and vein
Superior vena cava
Inferior vena cava
Vessels transporting oxygenated blood depicted in red and vessels transporting deoxygenated blood depicted in blue
CIRCULATORY PATHWAY
typically have a thicker tunica media and smaller lumen
arteries
arger lumen and the thickest layer is the tunica adventitia
veins
Thin membranous membrane, protective sac which contains a small amount of lubricating fluid to protect the heart and cushion it movements
PERICARDIUM
Endocrine gland, partially obscures the heart anteriorly
THYMUS
CIRCUIT From heart to lungs and back
PULMONARY CIRCUIT
CIRCUIT From the heart to the rest of the body and back
SYSTEMIC CIRCUIT
4 CHAMBERS OF THE HEART
RIGHT VENTRICLE/ LEFT VENTRICLE
RIGHT AURICLE/ LEFT AURICLE
Pump blood out of the heart to the lungs and to the rest of the body respectively
Separated by interventricular sulcus
RIGHT VENTRICLE/ LEFT VENTRICLE
