  3. left ventricle of heart

  4. right atrium of heart

  5. left atrium of heart

  1. conus arteriosus

  2. sinus venosus

  3. atrium

  4. ventricles

  5. carotid arches
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The conus arteriosus is a conical pouch formed from the upper and left angle of the right ventricle in the chordate heart from which the pulmonary trunk arises. Pylangium (the first and undivided part of the aortic trunk in the amphibian heart) is present here.
