Vedclass · Answer

(B) The provided figure represents the open circulatory system of an arthropod (like a cockroach). In this system: $P$ represents the valve that prevents backflow of blood. $Q$ represents the ostia (pores) through which blood enters the heart. $R$ represents the heart (pump) which circulates the blood. $S$ and $U$ represent the arteries that carry blood away from the heart. $T$ represents the haemocoel (body cavity) where blood is released. Therefore,the correct sequence is $P$ - Valve,$Q$ - Ostia,$R$ - Pump,$S$ - Artery,$T$ - Haemocoel,$U$ - Artery.
