Arteries and Veins are the major parts of the blood circulation system in any animals on the planet.both play and important role in human body also.the main purpose of these is blood circulation but there is a slight difference between arteries and veins i.e arteries are the blood vessels which take blood away from the heart to the other parts of the body. they are thick and have stronger and.
The Circulatory System. Veins, arteries and capillaries are the three types of blood vessels in the circulatory system. The blood vessels carry blood, which contains antibodies, nutrients, oxygen, electrolytes and hormones, throughout the body to be used by the organs.
Arteries, veins and capillaries What is blood Blood is the liquid which flows through your body. It is made up of red blood cells (which carry oxygen around the body), white blood cells (which defend the body against bacteria), Plasma (which carries glucose and sugar.
Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between. Arteries deliver oxygenated blood to the capillaries, where the exchange of oxygen and carbon dioxide takes place. An artery's muscle helps it expand and contract in rhythm with the heart beating to keep blood moving through the system.
From the aorta the blood travels through arteries and then through the capillaries. The heart has one-way valves to stop backflow of blood. The left side of the heart and the right side of the heart are separated by a wall of muscle called a septum. The septum ensures there is no mixing of the deoxygenated and the oxygenated blood. Due to the four-chambered heart mankind is homeothermic.
The blood vessels are divided into three types, namely, arteries, veins, and capillaries. The difference of veins and arteries can be known when we see it from the side of the cardiovascular system. Cardiovascular system responsible for supplying nutrients and oxygen to all tissues of the body. In addition, the system consists of the heart and.
