40) Describe the structure of a mammalian respiratory system. Include in your discussion the mechanisms of inspiration and expiration. In mammals‚ oxygen first passes through the nasal cavity. The nasal cavity is covered with mucus and cicilia to filter the air. The nasal cavity leads to the pharynx. The pharynx consists of the eustachian tube and the tonsils. The inhaled air then passes to the larynx‚ trachea‚ and bronchi. The bronchi lead to the bronchioles in the lungs. In the lungs the pleural

The extreme temperatures of the water cooled to 0°C‚ and heated to 94-100°C will greatly damage the membranes. Extreme heat will be more damaging than extreme cold. The more concentrated the solvent‚ the more damage it will cause to the membranes‚ therefore the

variables thought to affect drag were tested. Previously tested variables were weight and surface area. It was found that weight had an inverse exponential effect on time it took the coffee filter to fall to the ground‚ while surface area had an inverse linear effect. After multiple iterations of this experiment‚ two observations were points of discussion. While height was kept constant during each iteration‚ it was noticed that

McGowan Goldfish Respiration Lab Introduction The purpose of this experiment was to recognize the effects of temperature on the breathing rate of goldfish (Carassius auratus). Goldfish obtain oxygen from the water; the fish have to distribute the oxygen from the water into their bloodstream. This transfer of oxygen occurs over a surface area of capillary membranes contained in the feathery filaments of the gills located beneath the operculum. According to “The Respiration System of a Goldfish”
