Blood flows through vessels

Vedclass · Answer

(D) In an open circulatory system,blood is pumped out of the heart into body cavities or sinuses called haemocoel. Because the blood is not confined to vessels,it flows at a low pressure. Respiratory pigments may or may not be present in open circulation (e.g.,insects lack respiratory pigments,while molluscs may have haemocyanin). However,the defining characteristic of a closed circulatory system is that blood flows through a continuous network of blood vessels. Therefore,the statement that blood flows through vessels is characteristic of a closed circulatory system,not an open one.
