The Creation of Man by Prometheus (by J.M. Hunt) Prometheus and Epimetheus were spared imprisonment in Tartarus because they had not fought with their fellow Titans during the war with the Olympians. They were given the task of creating man. Prometheus shaped man out of mud, and Athena breathed life into his clay figure. Prometheus had assigned Epimetheus the task of giving the creatures of the earth their various qualities, such as swiftness, cunning, strength, fur, and wings.
The organs in your body need oxygen to survive. Oxygen is carried through the body by the blood. When the heart beats, it creates pressure that pushes blood through a network of tube-shaped arteries and veins, also known as blood vessels and capillaries.The pressure --- blood pressure --- is the result of two forces.ealthy arteries are made of muscle and a semi-flexible tissue that stretches like elastic when the heart pumps blood through them. The more forcefully that blood pumps, the more the arteries stretch to allow blood to easily flow.
The function of veins, arteries and capillaries are reflected in their structure. The walls of the capillaries are relatively thin and made of flat endothelial cells to facilitate exchange of gases, nutrients, and waste between the blood and the fluid surrounding the cells.Arteries, by contrast, have thick, strong walls to withstand the high speed and pressure of blood pumped from the heart.owever, for larger animals, the exchange of gases and nutrients is accomplished through specialized systems for circulation and gas exchange. Humans and other vertebrates have a closed circulatory system where blood is confined to the heart and blood vessels.
