The circulatory system of the human body is composed of many large and small blood vessels that transport blood throughout the body. The largest artery in the human body is the aorta. This blood vessel is responsible for pumping oxygenated blood from the left side of the heart to the head and body. The aorta is attached to the left ventricle of the heart.
Although there are many different species of both wallabies and kangaroos that span a wide range of sizes, wallabies only tend to weigh between four pounds and 53 pounds (2 kg to 24 kg) and grow a mere 12 inches to 24 inches (30 cm to 104 cm) tall, not including their tails [source: Wallaby].
There are dozens of species of wallaby. The top speed of the average wallaby is about 48 kilometres per hour, which equates to around 30 mph. 7 people found this useful. Edit. Share to: On the Wallaby. One of my favourite past-times is driving and exploring with my husband (and my dog).
