factors affects oxygen dissociation curve - carbon dioxidecarbon dioxide lowers the oxygen affinity of haemoglobin even if the ph is kept constant
factors that affects oxygen dissociation curves - temperatureat higher temperature haemoglobin gives up oxygen more readily and the dissociation
factors that affects oxygen dissociation curvesoxygen dissociation curve for a sample of blood is affected by several factors the most important of
myoglobinwe can build up the structure of haemoglobin by considering a single unit or monomeric form caned myoglobin this consists of a single
tracheal gills - respirationin many species of aquatic insects the air in the trachae is replenished by diffusion of oxygen via tracheal gills many

ventilation of tracheal system ndash passive suction ventilationmany active insects and insects that live in environments where water is scarce
ventilation of tracheal system - diffusiongaseous exchange due to diffusion generally takes care of the oxygen needs of most small insects similarly
ventilation of tracheal systemthe manner in which tracheae are ventilated varies with species of insects but movement of air is achieved in two ways
tracheae - respirationinsects that have successfully colonised the terrestrial environment have evolved a respiratory system very different from
regulation of respirationwhenever the need for oxygen in the body increases ventilation of the respiratory organs also increases in the same way

ram ventilationsome fish do not use pumping action for gill ventilation it has been known for long that large tunas cannot be kept alive in captivity
ventilation of gillsvarious mechanical devices are used to increase the flow of water over the gills surface there can be two means of increasing the
gills -respirationgills are highly vascularised extensions of gas exchange membranes the simple type may be extension of the body surface as in
circulatory systems in animalsin animals that have efficient circulatory systems and readily permeable vascular skins gas exchange occurs through the
modes of respirationmany small organisms obtain oxygen by diffusion through their body surfaces they do not have any specialised respiratory organs
diffusion of gases gases diffuse from areas of higher partial pressure to areas of lower partial pressure the diffusion along the partial pressure
respiratory gases -respirationphysiologically the most important gases are oxygen carbon dioxide and nitrogen molecular oxygen comprises 21 of the
respirationit is important that you comprehend the main points because they ate essential for your understanding of respiratory physiology to enter
energy storage as we said above food intake and energy expenditure for animals is approximately equal if energy expenditure exceeds food intake then
energy metabolismin the preceding sections of the unit you studied how the products of digestion of food viz amino acids sugars and fatty acids are
coordination of digestion you have learnt that digestion is a process in which large food molecules arc broken down step by step into their
maintenance of gut liningafter studying the digestive enzymes you would wonder why the gut linings are not digested themselves this is because
lipid digestion digestion of fats is also similar in both invertebrates and vertebrates lipases are the - enzymes that hydrolyse fats a single lipase
