Blood returning to the mammalian heart in a pulmonary vein drains first into the vena cava left atrium right atrium d left ventricle

The heart is in during the second heart sound dub of the cardiac cycle atrial systole the process of closing the semilunar valves ventricular systole the process of closing the atrioventricular valves

Why is it not lethal for amphibians to mix oxygenated and deoxygenated blood in their three chambered heart a b C d Amphibians can respire though their skin which helps oxygenate the mixed blood Amphibians use gills to oxygenate their blood from their environment directly Amphibians heartbeats prevent mixing of oxygenated and oxygenated blood by pushing blood through the pulmonary circulation first then to the systemic circulation before blood is returned to the heart Amphibians do not mix their oxygenated and deoxygenated blood

Current River B waterfall A Windy City Spring Cave 11 05 E D Wet Creek C Finn s Farm Swan Lake Case Study How Does Human Activity Affect Rivers Alice and her classmates visited a nearby river Their goal was to determine if pollution from cities and farms affected the water quality of the river Water quality describes the condition of the water including chemical and physical properties as well as biological characteristics Their first task was to take water samples from five sites along the river Alice wore long waterproof waders and collected samples at site A by submerging a container under the water She also measured water temperature at 65 F She took notes in her field journal about what she observed at the location There was a small waterfall upstream from her collection site and the water was clear Next she collected invertebrates from the site by placing a net in the water and disturbing the rocks nearby The current would carry any animals into the net and then deposited into a bucket to examine back at the lab She returned to the lab with her samples which would then be compared to samples taken at the other locations 1 Summarize the data collected by Alice Qualitative Quantitiative Water quality 8 4 WATER QUALITY Zobrane i River Map Showing Sample Sites A E 2 How did Alice collect invertebrate samples Placing a net in the water and clisturbing nearly rocks 3 What is the purpose of this study 4 Examine the river map What differences would you expect to find from water sampled at Site A to water collected at Site B
