Vedclass · Answer

(C) In an open circulatory system,blood is pumped by the heart into body cavities,where tissues are surrounded by the blood. This system lacks a complete network of blood vessels,meaning blood capillaries are absent. Key features of open circulation include: $1$. Blood flows at low pressure. $2$. The body cavity is known as the haemocoel. $3$. Respiratory pigments are often absent or dissolved in the plasma rather than contained in cells. Therefore,the presence of blood capillaries is a characteristic of a closed circulatory system,not an open one.
