Why are the arteries found on the outside of the heart?
Interesting question. I'd presume that as the heart is constantly pumping blood, the oxygen in the blood will diffuse into the cells that make up the inner part of the muscle of the heart. This is a slow process, however, and the heart needs a lot of oxygen, so it has arteries on the outside of it. This would mean the heart muscle is getting a rich supply oxygen from both sides of the muscular wall, allowing it to work as efficiently as it does.
What is the function of the blood vessels on the outer wall of the heart?
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.
What is the purpose of the coronary artery and what happens if there is a blockage?
Coronary artery bypass graft surgery (also called coronary artery bypass surgery [CABG] and bypass operation) is performed to restore blood flow to the heart. This relieves chest pain and ischemia, improves the patient's quality of life.
What tissue organ and body system are affected by a heart attack?
Myocardial Infarction affects the heart's ability to pump adequate oxygenated blood, nutrients, water and hormones to the rest of the body. It can affect the brain if too much oxygen is deprived from the brain or any other organ for that matter. If the person is treated rapidly and can be saved measures will be take to restore the heart and any other affected organ to better health.
Could the heart beat without the autonomic nervous system?
yes, the heart has its own pacemaker. The autonomic nervous system, while it can effect the heartbeat, cannot initiate it. That's the job of the Sinoatrial node located in the right atrium. It triggers an electrical impulse that travels down the right atrium, between the ventricles, and up the sides of the heart. This electrical impluse is what causes the heart to beat.
A muscle such as the heart muscle that does its job without thinking about it?
involuntary muscles
What is a muscle such as the heart muscle that does its job without thinking about it?
heart brain the digestion track the lungs
What muscle such as the heart muscle does its job without thinking about it?
Involuntary muscles contract subconsciously.
What is the job of the cardiac muscle?
The job is that it protects your heart and lungs and it never tires from doing its job. It is also a involutary muscle which is a muscle that is not under your conscous control. The job is that it protects your heart and lungs and it never tires from doing its job. It is also a involutary muscle which is a muscle that is not under your conscous control. The job is that it protects your heart and lungs and it never tires from doing its job. It is also a involutary muscle which is a muscle that is not under your conscous control.
Why do they say that the heart is a muscle?
Because your heart is a muscle, a cardiac muscle. a muscles job is to contract an that is exactly what the heart does, it contracts to pump blood.
In the heart what job dos the muscle tissue have?
The heart is made up of muscle tissue (cardiac muscle). The muscle tissue contracts to pump blood.
What is the primary function of a cardiac muscle cell?
The job is that it protects your heart and lungs and it never tires from doing its job. It is also a involutary muscle which is a muscle that is not under your conscous control.

What job does a muscle have?
That depends on what muscle you're talking about. A skeletal muscle pulls the bone and causes the joints(and the body part) to bend. Without it, we would not be able to do even the simplest errands because we can't move a thing. Smooth muscle is the muscle of the organs(excluding the heart), blood vessels. Smooth muscle is not under voluntary control, meaning you don't have any control over it. Without it, you won't be able to move any of your organs, or move blood well throughout your body. Cardiac muscle is simply the muscle of the heart. The heart is the only place that has this muscle and this also is involuntary. Without it, you will not be able to pump blood throughout your body, and because of lack of oxygen, you will die.
Muscle is the ability of your muscles to do their job over a period of time without becoming tired?
Endurance is your muscle's ability to do their job over a period of time without tiring.

What is the only cardiac muscle and what is it job?
There is 2 main cardiac muscles. The heart, which pumps blood; and all the arteries in your body, which are actually a muscle because they squeeze in sync with your heart rate to keep your blood flowing
What are mucles?
Muscle is a body parts in side of ous. There are three different types of muscle the Skeletal,Smooth and the Cardiac. The skeletal muscle is the muscle that you can see and feel its also a voluntary muscle that means you choose to move them. The Smooth is in your digustive system it helps you move along the food. The Cardiac is the muscle in your heart it has a job of pumping all the blood out from the heart.
