Types ofCIRCULATORY SYSTEMS • OPEN CIRCULATORY SYSTEM • HEMOLYMPH (Blood) bathes organs • DOES NOT stay in blood vessels • Collects in sinuses (body cavity) for return to heart • Less efficient • INVERTEBRATES
Types ofCIRCULATORY SYSTEMS • CLOSED CIRCULATORY SYSTEM • Blood stays in blood vessels • Arteries carry blood away from heart • aorta largest artery in body • Veins returns blood to heart • Capillaries connects arteries to veins • Very efficient • VERTEBRATES
Types ofCIRCULATORY SYSTEMS • SINGLE CIRCULATORY SYSTEM • Blood enters the heart ONCE • then travels directly to the body • Pumped to anterior first
Types ofCIRCULATORY SYSTEMS • DOUBLE CIRCULATORY SYSTEM • DEOXYGENATED Blood enters heart then is pumped to lungs • Picks up oxygen / releases carbon dioxide • OXYGENATED Blood returns to heart • Pumped out of heart through AORTA to body
GRASSHOPPER CIRCULATORY SYSTEM • SINGLE CIRCULATORY SYSTEM • OPEN CIRCULATORY SYSTEM • Transports nutrients and wastes
GRASSHOPPER CIRCULATORY SYSTEM • DORSAL HEART (tubular) • OSTIA pores in heart that collect hemolymph • AORTA large artery • Carries hemolymph to anterior • Hemolymph collects in coelom (body cavity) • Returns to heart
GRASSHOPPER RESPIRATORY SYSTEM • Exchanges gases • SPIRACLES1 pr located on lateral ventral of each abdominal segment except for the last segment • Lead to TRACHEAL TUBES • Wing movement aids in respiration
GRASSHOPPER RESPIRATION • Wings open • Abdomen expands creating vacuum • Oxygen is pulled in through spiracles • Travels through tracheal tubes • Oxygen is used / carbon dioxide released • Wings close • Abdomen contracts pushing out CO2
