Do Sharks Have A Open Or Closed Circulatory System?

Open circulatory system.

How Is The Sharks Respiratory System Different From A Human’S?

However, there are some notable differences between the two. For example, sharks have a two-chambered heart (consisting of an atrium and ventricle), while humans have a four-chambered heart (consisting of two atria and two ventricles). Additionally, sharks lack a pulmonary circulation system and instead rely on their gills to exchange oxygen and carbon dioxide.

Do Sharks Have A Two-Chambered Heart?
