THE IMPORTANCE OF OXYGEN IN ANIMALS
Oxygen is needed in animals in order for them to live. The process in which breathing occurs starts from taking breaths externally through our noses or our mouths. The air goes through the trachea into the bronchi & end up In the alveoli. Oxygen is taken into there body going to the blood while carbon dioxide is released. Respiration is what provides energy & is needed In all animals. Cellular respiration uses sugar & oxygen to make water, energy, & carbon dioxide. The animals mitochondria breaks down nutrients and changes them to energy. The chemical energy in Glucose which is used to make ATP. ( 6 C02 + 6 H2O + Energy (ATP) )
Gas exchange in florida crAyfish
Gills are organs that allow for gas exchange, oxygen goes in the "blood", which is actually called hemolymph in a crayfish, and carbon dioxide has to go out. For efficient breathing, one needs to maximize the surface area where the gas exchange occurs. [1] The gills on a crayfish helps more in the respiration process. The gills are used to get the amount of oxygen needed from the water. [2]
