These tubes then bring the water to the siphon, which forces the water to leave the body, and this allows the clam to breathe. Yet, clams often end up on shore, and during these droughts, respiration must occur on the surface of the clam's mantle and body, using the air to enable breathing. The Columbus Instruments Comprehensive Lab Animal Monitoring System (CLAMS) is a system of metabolic cages which allows for simultaneous measurement of numerous metabolic parameters including: Oxygen consumption (VO2) Carbon dioxide production (VCO2) Respiratory exchange ratio (RER) Running Wheels. Although the respiratory system of a spider is much simpler compared to mammals, the inner workings of a spider are amazing. Most molluscs have only one pair of gills, or even just one gill.They divide the. They do not have a respiratory system, however they recieve oxygen like leeches and earthworms do.

The open system of the clam … There is neither a circulatory nor respiratory system, with gas and nutrient exchange dependent on diffusion and cell-cell junctions. The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.
