Animal Circulation and Respiration SUNY Orange at S. S. Seward Institute External gills of a salmon Evolution of Circulation Prokaryotes – diffusion Unicellular eukaryotes – cyclosis Aquatic invertebrates –Jellyfish –hydra Aurelia (moon jelly) Internal transport in the cnidarian Aurelia Open and closed circulatory systems Generalized circulatory schemes of vertebrates The mammalian heart: a closer look Overview: mammalian cardiovascular system The cardiac cycle The control of heart rhythm The structure of blood vessels The interrelationship of blood flow velocity, cross-sectional area of blood vessels, and blood pressure Blood flow in veins Atherosclerosis: normal artery and artery with plaque Blood flow in capillary beds The interrelationship of blood flow velocity, cross-sectional area of blood vessels, and blood pressure Sphygmomanometers Measurement of blood pressure Measurement of blood pressure Measurement of blood pressure Measurement of blood pressure Hypertension – high blood pressure The interrelationship of blood flow velocity, cross-sectional area of blood vessels, and blood pressure Hypertension Causes: The movement of fluid between capillaries and the interstitial fluid Blood smear The composition of mammalian blood Differentiation of blood cells Blood clot The role of gas exchange in bioenergetics Diversity in the structure of gills, external body surfaces functioning in gas exchange External gills of a salmon The structure and function of fish gills Countercurrent exchange Tracheal systems The mammalian respiratory system Negative pressure breathing Alveoli Alveolar structure of mouse lung Alveolar structure of mouse lung animation Pasta for Pennies 7th Grade ----- $ 1916.45 6th Grade ----- $ 860.24 8th Grade ----- $ 346.41 11th Grade --- $ 166.20 9th Grade ----- $ 35.16 12th Grade --- $ 26.51 10th Grade --- $ 7.99 The avian respiratory system Automatic control of breathing Loading and unloading of respiratory gases Oxygen dissociation curves for hemoglobin Dissociation curves for two hemoglobins Carbon dioxide transport in the blood The Weddell seal, Leptonychotes weddelli, a deep-diving mammal Consider the respiratory system in a human and the respiratory system in a diving mammal. What adaptations are present in the diving mammal and how to they work to maintain homeostasis while diving.
