Circulatory System
Spiders have an open circulatory system
Their blood flows through veins and arteries and is released into open cavities around the organs

Respiration
Spiders have developed different respiratory anatomies: book lung, a tracheal system, or both
Two pairs of book lungs where openings on the ventral surface of the abdomen allow air to enter and diffuse oxygen
Tracheal tubes are found less often but fuse together to form spiracles
