Arterial vs Venous Blood Although these terms may sound a little familiar, the particulars are not commonly known. Therefore, the importance of bringing up the particular properties of venous and arterial blood would make more sense in understanding those. This article will not only discuss the properties, but also emphasize the differences between them.
The human arterial and venous systems develop from different areas in the embryo. The arterial system develops mainly from the aortic arches, six pairs of arches which develop on the upper part of the embryo. The venous system arises from three bilateral veins during weeks 4 – 8 of embryogenesis.
The deep venous system includes the iliac, femoral, popliteal and deep femoral veins. The deep veins generally run parallel to the corresponding arteries. These two venous systems are separated from each other by connective tissue fascia and muscles and are connected by a third venous system – the perforating veins (=communicating veins).
Arterial System of Frog source:notesguidebook.blogspot.com fig:Arterial System of Frog. Blood vessels, which carry oxygenated blood away from the heart to the different part of the body, are called arteries. They constitute a system called arterial system. Truncus arterious gives two branches right aortic trunk and left aortic trunk.

Arterial blood and venous blood are two types of blood found in the blood vessels of a closed circulation system. Arterial blood is rich in oxygen and nutrients. But, venous blood is rich in metabolic wastes such as carbon dioxide and urea. Since arterial blood is rich in oxygen, the color of the blood is bright red.
Distinguish the venous system from the arterial system. Key Takeaways Key Points. The difference between veins and arteries is the direction of blood flow (out of the heart through arteries, returning to the heart through veins). Veins differ from arteries in structure and function. For example, arteries are more muscular than veins, veins are ...
In particular, arterial thrombosis has long been held to be largely a phenomenon of platelet activation, whereas venous thrombosis is largely a matter of activation of the clotting system. However, there is evidence that this dichotomy is likely to be an oversimplification.
The venous system within the cardiovascular system. The venous system is an integral part of the cardiovascular system which is designed to circulate blood allowing gaseous and metabolic exchanges within the billions of cells making up the body. The cardiovascular system is a closed circulatory system in which blood flows in one direction only.
Veins return blood to the heart from all the organs of the body. The large veins parallel the large arteries and often share the same name, but the pathways of the venous system are more difficult to trace than those of the arteries. Many unnamed small veins form irregular networks and connect with the large veins.
