• cardiovascular system


  composed of heart and all the vessels that serve as a highway for the transport of blood
• Heart


  served as the pump contracting rhythmically to bring appropriate pressure.
• Heart


  maintain the flow of the blood
• Mediastinum


  heart is located within what structure?
• Mammals and Birds


  These 2 species has 4 chambers
• 4 chambers


  How many chambers does mammals and birds have?
• FALSE; it is obvious


  TRUE or FALSE: Variation is imperceptible in the size as larger animals need a larger heart to compensate for the demand for higher pumping pressure.
• Pig


  Identify: This is the heart of what animal?

  Sheep's heart is located between what rib?
• False: Laterally


  TRUE or FALSE: Horse heart is ventrally compressed cone
• Horse


  This animal has laterally compressed cone heart
• Horse


  Heart of this animal lies in the ventral part of the middle mediastinum, directly cranial to the diaphragm and largely covered by the forelimbs;
• True


  True or False: Horse heart lies in the ventral part of the middle

• Left ventricle


  Chicken's apex is formed solely by what ventricle?
• Liver


  dorsal and lateral aspects of the heart lie in contact with, what organ?
• Right atrium


  In avians, this atrium receives the caudal vena cava and a pair of cranial venae cavae.
• CVaudal vena cava and

  A pair of cranial venae cavae.


  In chicken, the right atrium receives the
• Left atrium


  In avians, this atrium receives the oxygenated blood via a single common pulmonary vein.
• oxygenated blood


  In chicken, the left atrium receives the
• single common pulmonary vein.

  In avians, left atrium recieves the oxygenated blood via what structure?
• False; similar


  True or False: In chicken, the ventricles are different to those of mammalian hearts.
• Dog


  Identify: This is the heart of what animal?
