1. GRASSHOPPER ORGAN SYSTEMS

2. Types of CIRCULATORY 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

3. Types of CIRCULATORY 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

4. Types of CIRCULATORY SYSTEMS SINGLE CIRCULATORY SYSTEM Blood enters the heart ONCE then travels directly to the body Pumped to anterior first

5. Types of CIRCULATORY 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

6. GRASSHOPPER CIRCULATORY SYSTEM SINGLE CIRCULATORY SYSTEM OPEN CIRCULATORY SYSTEM Transports nutrients and wastes

7. 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

8. GRASSHOPPER RESPIRATORY SYSTEM Exchanges gases SPIRACLES 1 pr located on lateral ventral of each abdominal segment except for the last segment Lead to TRACHEAL TUBES Wing movement aids in respiration

9. 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
