The Cardiovascular System is responsible for transporting nutrients throughout the body and removing gaseous waste from the body. In the Chordata phylum, the hearts of the animals seem to be larger, they seem to have longer blood vessels due to their larger bodies. Chordates tend to have bilateral symetry. This means that they have the same amount of blood vessels on each side of their body. Chordates have body cavities, which are enclosed by a membrane the is almost like tissue. The heart is located inside this cavity. This cavity is almost always located in the chest in a chordate unlike other animals. The notochord, which is used to give structures to animals, is a defining feature of chordates. This can affect how the circulatory system is placed in less advanced chordates.
Tigers- Tigers have a closed double loop circulatory system. This means that tigers keep their blood in blood vessels not like some animals who let their blood move around in the body openly.
Lions- Lions also have a closed double loop circulatory system. The double loop circulatory system allows the blood to travel through the body and back, which helps it take nutrients in and expel waste.
Bears- Bears have hearts with four chambers. The right ventricle, left ventricle, right atrium and left atrium. This helps the bear pump blood through veins and arteries with half, and to take in unoxidized blood and combine it with oxygen.
These animals, all being mammals not only have almost exactly the same cardiovascular systems with each other, but with humans as well. All of these qualities mentioned are in all three animals and humans. This suggests that an animal like a bird or a snake would have a different cardiovascular system, due to their shapes and if they are warm or cold-blooded.
