Vedclass · Answer

(D) closed circulatory system is characterized by blood flowing through a series of vessels (arteries,veins,and capillaries). In this system,blood pressure is generally higher and more regulated compared to an open system. The volume of blood is limited as it remains confined within the vessels. Option $D$ states that the heart contains valved ostia; this is a characteristic feature of an open circulatory system (e.g.,in arthropods like insects),where blood flows into sinuses and enters the heart through these ostia. Therefore,this statement is inconsistent with a closed circulatory system.
