Grasshopper organ systems

GRASSHOPPER ORGAN SYSTEMS


Types of circulatory systems

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 of circulatory systems1

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 of circulatory systems2

Types ofCIRCULATORY SYSTEMS

  • SINGLE CIRCULATORY SYSTEM

  • Blood enters the heart ONCE

  • then travels directly to the body

  • Pumped to anterior first


Types of circulatory systems3

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

GRASSHOPPER CIRCULATORY SYSTEM

  • SINGLE CIRCULATORY SYSTEM

  • OPEN CIRCULATORY SYSTEM

  • Transports nutrients and wastes


Grasshopper circulatory system1

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

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

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
