1. because of genes- hereditary! 2. because of teeth decay,this leads to bad blood in direct contact with heart! 3. food habits.. obesity
There is no scientific proof that direct heart to heart contact between Mother and child can restart a childs heartbeat.
Arteries direct blood away from the heart, while veins direct blood to the heart.
The structure located closest to the center of the heart is the myocardium, which is the thick muscular layer responsible for the heart's contraction. Surrounding the myocardium is the endocardium, which lines the heart's chambers. The innermost layer of tissue, the endocardium, is in direct contact with the blood flowing through the heart.
Veins (vena-cava) direct venous blood to the heart, the coronary arteries direct arterial blood to the heart.
Effleurage strokes that are centripetal (towards the heart) are most often performed on the extremities, like the arms and legs, because it is important to direct the blood flow towards the heart in the veins to prevent damage to their valves.
The ventricles is the lower heart chambers not the blood vessels that direct blood toward the heart.
open circulatory system is the type of circulatory system in which blood vessels have direct contact with body tissues.the whole blood from body goes to heart and then passed in blood vessels which have direct contact with open spaces called sinuses after exchange of materials the blood goes back to heart. almost all invertebrates have open circulatory system such as Arthropoda.
Veins are blood vessels that direct blood toward the heart.
Veins are blood vessels that direct blood toward the heart.
arteries direct blood to the body and vessels direct it back to the heart. I dont know their exact name
Heart is injured by cardiac diseases such as miocardial infarction , arrythmias etc . But it is difficult to become injured by direct trauma because heart is greatly protected by chest wall . But even it can be injured by gunshot wound .
