The largest artery in your body is the Aorta. The largest vein in the body is Vena Cava. The aorta is the largest blood vessel in the body. It is an artery that directly arises from the heart itself and descends through the thorax and into the abdomen. All the arteries of the body, save the pulmonary arteries, stem from the aorta or one of its main branches.
There are many different dinosaur books that state different sizes of the tyrannosaurus rex. These sizes range from 40 feet long to 49 feet long. It's maximum length was probably close to 50 feet long. The paleantologists have only found remains, incomplete remains, of the Tyrannosaurus.
In terms of size, the Stegosaurus was large and heavily built. On average, a fully grown Stegosaurus was around 9 metres (30ft) in length, 4 metres (14ft) in height and up to nearly 5 metric tons in weight.Although the Stegosaurus body was large, the size of their brain was only around the size of a dogâs.esearchers believe that due to the nature of Stegosaurus legs, they had a maximum speed of around 7kph (5mph). The 17 plates found along the back of the Stegosaurus arose from the skin rather than being attached to the skeleton. The largest plates were around 60cm (2ft) tall and 60cm (2ft) wide.
