What tissue helps operation of all four heart valves?

Pericardial heart valves:
The pericardial heart valve was invented by Marian Ionescu, a British surgeon working at the General Infirmary in Leeds, England.[1] He created this artificial bioprosthetic heart valve as a three cusp structure made of chemically treated bovine pericardium attached on to a Dacron cloth covered Titanium frame.[2]

What flaps of tissue helps the blood to only flow in one direction?
they're called valves. they are found in veins and also in the heart. hope this helped!
What about the other parts of the heart are they muscles too?
No. The heart is an organ. Organs are made of more than one tissue. The valves of the heart are made of strong connective tissues. They are so strong and large they form what is called the skeleton of the heart and helps to give it shape.
What are flaps of tissue that allow blood to flow in only one direction?
They are called valves, or leaflet valves in the veins, that interlock to prevent backflow of the blood.
What type of tissue makes up nonconducting skeleton of the heart?
Muscular
What are the three types of muscle tissue and what dod they do?
The three types of muscle tissue are:smooth, cardiac, and skeletal. The smooth muscle tissue moves your internal organs, the cardiac muscle tissue helps your heart beat, and the skeletal muscle tissue helps you move your skeleton.

Possible Damage To The Heart Valves?
The heart is a specialized muscle that delivers the power to circulate the blood throughout the body. Comprised of four chambers and a series of valves, it is in constant operation and maintaining a healthy heart is the responsibility of its owner. Damaged heart valves can be the result of a poor diet, lack of exercise, the use of tobacco and an excessive intake of alcohol.How Heart Valves Can Become DamagedIf the arteries that supply the heart with blood become constricted or narrowed, the flow of blood to this organ is decreased. Over time some of the muscle tissue will begin to degenerate as the cells cannot reproduce as efficiently as before. This puts extra pressure on the heart valves, which themselves can slowly change their shape, becoming narrowed or stenosed, and are sometimes perforated. When the valves are not opening and closing properly the blood flow to the lungs and the rest of the body is affected to a significant degree.Repairing A Heart ValveOften an exploratory surgery is necessary to determine if a damaged heart valve can be repaired through a tailoring process. Stenosed heart valves may have to be cut to relieve their stiffness and make the opening to the heart chamber larger. A valve that has become tightened often will not close properly because of excess tissue that must be cut away. Since some valves open to the ventricles of the heart while others open to the aorta and pulmonary artery, the direction of blood flow and the shape of the individual valve determines whether this type of surgery is the best option.Replacement Of A Heart ValveThis can be a complicated procedure due to the shape of certain heart valves and the extent of the damage. Replacing a heart valve often involves the insertion of a prosthetic substitute, a mechanical device that functions the same way as the original tissue. After this procedure is performed the patient is usually put on a permanent prescription medication that helps to prevent clotting around the mechanical valve. Another option is the use of animal tissue, usually from a cow or pig, which is sewn in to the linings where the original valve was located. In this procedure, the medication therapy is often not required, but these valves have a shorter lifespan and may themselves have to be replaced.Prevention of damage to heart valves means a healthy diet that is low in sodium, saturated fats and LDL cholesterol. Strengthening the heart muscle through daily exercise is the best way to keep this muscle organ functioning properly, and regular checkups to determine if there are any problems is highly recommended.
What is the purpose of the valves in the heart and the veins?
your semi lunar valves stop slop from entering your left aorta and your lunar valves stop crud from entering your right ventricle. this is the purpose of your valves. but this is different in dogs as your septum helps fight against testicular torsion.
Why do the hearts valve close?
In a 4-chambered heart animal, the valves on the heart close to prevent back-flow from the ventricle into the atrium. In this way, the valves assure that the heart propels the blood forward with sufficient pressure and volume to reach all regions of the body.
What brings blood to the lungs for gas exchange?
The heart pumps blood to the lungs to be reoxygenated. Valves in our veins and the muscle contractions of our legs helps bring blood from the lower limbs to the heart.
It helps the heart pump oxygen around the body this tissue can also cause heart cancer Without this tissue our heart wouldn't have enough strength to pump blood around the body?
the heart pumps oxygenated blood round the body so that the muscles get oxygen to help them be used in energetic exercises
Why does the heart has different types of tissues?
The heart does consist or atria, ventricles, etc. but these are the gross, anatomical divisions of the heart. In asking about the kinds of tissues contained in the heart, we have to think of the cells found there. The heart obviously contains cardiac muscle, it is practically the only site where it is found, except for the transitions between the heart and the large vessels arising from it. Cardiac muscle consist of the typical cardiac muscle cells, which are di-nucleated, branched cells which connect to each other at intercalated disks, making the heart muscle a functional syncitium. In addition, the heart contains modified cardiac muscle cells called Purkinje cells. These cells transmit electrical impulses to the ventricles, to stimulate them to contract. The heart also contains connective tissue, serving various purposes, such as binding groups of cardiac muscle cells into fascicles, etc.
