  • support metabolism 
  • Maintain homeostasis
  • transport + distribute hormones

TESTE DEIN WISSEN
What type of circulatory system do insects usually use 
Lösung anzeigen
TESTE DEIN WISSEN
  • Open
  • heamolymph - moves out of vessels into open space 
  • direct cell contact

TESTE DEIN WISSEN
What are the general principles of a closed circulation system 
Lösung anzeigen
TESTE DEIN WISSEN
  • Fully enclosed - does not directly contact cells 
  • vertebrates
  • high pressure - high efficiency

TESTE DEIN WISSEN
What is the general principle of an open circulatory system 
Lösung anzeigen
TESTE DEIN WISSEN
  • Fluid open to body cavity 
  • direct contact to cells 
  • low pressure and low efficiency 
  • molluscs/arthropods

TESTE DEIN WISSEN
What are the five requirements for a circ system to be efficient 
Lösung anzeigen
TESTE DEIN WISSEN
  • Have O2 carriers
  • have gas exchange barrier 
  • Delivers nutrients and gases 
  • Fast flow
  • efficient gas exchange tissue

TESTE DEIN WISSEN
What are common features of an open circ system
Lösung anzeigen
TESTE DEIN WISSEN
  • Incomplete vessel system 
  • have circulating fluid - haemolymph 
  • heamolymph flows through Vessels and freely flows into the intercellular space 
  • heart(s) may propel heamolymph

TESTE DEIN WISSEN
How do pumps vary within different close circ systems 
Lösung anzeigen
TESTE DEIN WISSEN
Anatomy differs
diff number of chambers/arrangement of flow is different

TESTE DEIN WISSEN
What mechanisms do closed circ systems use for exchange 
Lösung anzeigen
TESTE DEIN WISSEN
  • Capillaries
  • 1 cells thick
  • allow for gas/nutrient exchange 
  • varies

TESTE DEIN WISSEN
How do distribution patters vary in close circ systems 
Lösung anzeigen
TESTE DEIN WISSEN
Patters vary -single or double circuit 
Lösung ausblenden
TESTE DEIN WISSEN
What are the main features of a close circulation system 
Lösung anzeigen
TESTE DEIN WISSEN
  • Continuous blood vessels 
  • use blood - separate from cells 
  • heart(s) propel blood though vessels 
  • intercellular space = filled with interstitial fluid 
  • lymph in lymphatic vessels
