Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.

Why is the heart anchored to the diaphragm and what is the function of this anchoring?
The heart is anchored to the diaphragm in order to keep it in place. The diaphragm also reduces friction to the outer membranes of the heart.
Do muscular arteries maintain blood flow during ventricular diastole?
The structure of the various blood vessels is closely related to their function. The vessels which receive blood from the heart, the elastic arteries, have thick, strong walls to cope with the sudden high pressure produced during diastole; they contain abundant elastic material to allow stretch so that the vessel lumen may accommodate the change of volume. They also have a thick, outer coat of collagenous connective tissue whose tensile strength prevents over-distension of the elastic tissue. The elastic recoil of these elastic arteries is responsible for maintaining a continuous, though decreased, flow of blood to smaller vessels during systole.http://ect.downstate.edu/courseware/histomanual/cardiovascular.html

Where do blood vessels and nerves enter and leave the bone?
All bones have foramen in them. These are canals or openings through which nerves and blood vessels go.
The outer layer of blood vessels is composed of connective tissue called the?
tunica adventitia
What kind of tissue enables the blood vessels to stretch?
Blood vessels are surrounded by very small circular muscles which contract and relax to allow blood vessels to constrict and dilate. The vessels also contain elastin which allows them to stretch.
3 kinds of blood vessels?
There are 5 kinds of blood vessels. Arteries are the blood vessels that take blood away from the heart. Arterioles are the blood vessels that connect arteries and capllaries. Capillaries are the blood vessels that connect arterioles and venules. Venules are the blood vessels that connect capillaries and veins. Veins are the blood vessels that take blood to the heart. But mainly it is the capillaries veins and the arteries
