What is the difference between blood and hemolymph? - Blood: In a Closed circulatory system and is confined to vessels. Hemolymph (AKA interstitial fluid): In an Open circulatory system and bathes the body cells. What are the major types of blood cells? - red and white cells What adaptations allow an animal to use diffusion across its skin as the only mechanism for gas exchange? - The animal must be thin and have a large surface area. Animals that only diffuse across the skin have a dense network of capillaries just below the skin that allows for the exchange of gases. The respiratory surface is a thin, moist epithelium. What is the relationship between the surface area-to-volume ratio and efficiency of exchange across a surface? - Surface Area to Volume large ratio allows O2/CO2 gas exchange across whole body Not all animals use a circulatory system to transport oxygen and remove carbon dioxide. How do insects and some spiders accomplish gas exchange? - Insects have a tracheal system which includes spiracles (let air into the system) which are connected to tracheae that run very close to every tissue cell and allow for diffusion of gasses. In a two-chambered heart, where does the blood go after it leaves the atrium? (Give the entire pathway ending back in the atrium) - ventricle---Gills --- Body Capallaries--- Veins--- Atrium In a four-chambered heart, where does the blood go after it leaves the right atrium? (Give the entire pathway ending back in the right atrium) - Right ventricle--- Pulmonary Artery ---Lungs --- Pulminary Veins--- Left Atrium--- Left Ventricle
