The heart and blood vessels comprise the two elements of the cardiovascular system that work together in providing nourishment and oxygen to the organs of the body. The activity of these two elements is also coordinated in the body's response to stress.
graft vs fistula. A graft is usually in a horse-shoe or letter C shape, and is normally firmer to the touch. Fistulas usually run up and down and are more squiggly shaped, with bumps (pseudo anurisms) and softer to the touch. Here are some good pics of fistulas. For some reason, I could not find any pics of grafts on the net.
A fistula is an abnormal connection or passageway that connects two organs or vessels that do not usually connect. They can develop anywhere between an intestine and the skin, between the vagina and the rectum, and other places. Some fistulas include: Urinary Tract Fistulas. Abnormal openings within a urinary tract organ or an abnormal connection between a urinary tract organ and another organ. Vesicouterine fistula occurs between the bladder and the uterus. Vesicovaginal fistula is where a hole develops between the bladder and the vagina.
