What are five functions of the vertebrate circulatory system?

Amphibians have three-chambered hearts, which have some limitations when compared to the four-chambered hearts of birds and mammals. Describe a disadvantage of a three-chambered heart (in comparison to a four-chambered heart), and one way in which amphibians are able to compensate for it.

Birds and Mammals share which of the following characteristics? Ectothermy air pocketed bones bladders four chambered heart more than one of these

Use words from the word bank provided to fill in the spaces of the following paragraph: Word bank: respiratory, excretory, digestive, gas exchange, carbon dioxide, oxygen, nutrients, energy, tissues, cells, organs, gills, lungs, skin, diffusion, counter current, active transport, rich, poor, one, two, three, four In single circulatory systems blood vessels transport blood to the Blank 1 to become oxygenated using a Blank 2 (two words) mechanism. Blood within the heart is oxygen Blank 3, and the heart drives the blood around the body using Blank 4 chambers.

Refer to the figure below I. II II IV Reference: Ref 25-7 This circulatory plan belongs to which group of animals? Select one: O a. Fish O b. Invertebrates O c. Decapod crustaceans Od. Cephalopod molluscs

What are the important differences in the overall metabolic needs of a fish and a turtle and the ability of their circulatory systems to meet those needs? Select all that apply. Fish are less able to meet their metabolic needs than are turtles.  Fish have a two-chamber heart (one atrium and one ventricle) and turtles have a three-chambered heart (two atria and one ventricle). Turtles are endothermic and fish are ectothermic  Blood flows directly to other organs after being oxygenated in turtles, but return to the heart after being oxygenated in fish.  Turtles have a double,-circuit circulatory system whereas fish have a single circulatory system.
