concept 24 - BIO10008

what are the functions of animal circulatory systems

describe and justify the components needed in a circulatory system in animals

compare open and closed circulatory systems

summarise the general trend of structural changes between the closed circulatory systems in fish, amphibians, reptiles and mammals

what is the pathway oxygen takes in human circulatory system

identify and describe the three circuits of the mammalian circulatory system

artery

arteriole

capillary

venule

vein

what happens in the cardiac cycle

explain the features of the lungs that maximise respiratory gas exchange between alveoli and capillaries

explain how efficient exchange of substances occurs between capillaries and the interstitial fluid

kidney disease can result in decreased concentration of plasma in the blood which can result in oedema (abnormal increase in interstitial fluid). why this occurs using knowledge of capillary exchange

explain why an open circulatory system allows insects to continue living when they lose a limb/head

identify the advantages of a closed circulatory system
