Haemolymph bathes the organs and re-enters the heart through. Lots of past paper questions. Explain the part of the oxygen dissociation curve where there is a low saturation of haemoglobin with oxygen.

None of the haemoglobin molecules are carrying any oxygen. The heart uses blood vessels to transport these substances around the body. 0 saturation of haemoglobin with oxygen.

The diffusion or transport distance in these organisms are very small so essential nutrients or molecules are able to reach the necessary parts of the cell efficiently. Size large organisms that have cells further from the surface have surface-diffusion distance increased. Where pO2 is low eg in respiring tissues haemoglobin has a low affinity for oxygen.

They have one main blood vessel the dorsal vessel which delivers blood haemolymph into the haemocoel body cavity due to the pumping of a tubular heart in the abdomen. These are the answers to the Transport in Animals practice questions for A-Level Biology. Explain the part of the oxygen dissociation curve where there is a low saturation of haemoglobin with oxygen.

Transport in Animals a explain the need for transport systems in multicellular animals in terms of size level of activity and surface area. Where pO2 is low eg in respiring tissues haemoglobin has a low affinity for oxygenIt releases oxygen rather than combining with it. So outer cells would use all the resources.
