In a frog, heart is enclosed within a two-layered sac called
Options:
  • 1. Mesorchium
  • 2. Pericardium
  • 3. Pleura
  • 4. Conus arteriosus
Solution:
In a frog, the heart is enclosed within a two-layered sac called the pericardium. The pericardium is a fluid-filled sac that surrounds the heart and helps to protect it from damage. The pericardium has an outer fibrous layer and an inner serous layer, which is in contact with the heart. The pericardium also helps to keep the heart in place within the body cavity and prevents it from moving around too much during activity. The mesorchium is a membrane that attaches the testes to the body wall in male frogs. The pleura is a membrane that lines the inside of the thoracic cavity and covers the lungs in vertebrates. The conus arteriosus is a chamber in the heart of some animals, including fish and reptiles, but it is not present in frogs.
