Transportation and Circulation

• grasshopper - They have an open circulatory system with hemolymph
• frog - Their heart has two atrium and one ventricle. 
• flatworm - This is an example of an invertebrate without a circulatory system. 
• fish - Their blood follows a one-circuit circulatory pathway through the body. 
• human - Heart is divided into left and right halves.
• descending loop of henle - Part of the nephron where aquaporins allow water to pass from the filtrate into the interstitial fluid.   
• cohesion-tension theory - water moves up through the xylem
• decrease - This is what will happen to the transpiration rate of plants if the temperature decreases
• annelids - This animal developed an excretory cell called Nephridia
