What do you think will happen to the heart were injured or diseased?
If the heart is severely injured, people often die before they can be treated. However, many injuries worsen over hours or even longer. A tear in the wall of the heart (ventricular rupture) often causes fatal bleeding before people can be taken to a hospital.
What will happen if the tissues were injured?
Upon tissue injury, damaged cells release inflammatory chemical signals that evoke local vasodilation, the widening of the blood vessels. Increased blood flow results in apparent redness and heat. In response to injury, mast cells present in tissue degranulate, releasing the potent vasodilator histamine.
What would happen if one of the tissues in an organism is damaged?
Toxic damage to cells can cause individual cell death and if sufficient cells are lost, the result can be tissue or organ failure, ultimately leading to death of the organism.
Can damage to the heart heal?
Heart muscle damaged by a heart attack heals by forming scar tissue. It usually takes several weeks for your heart muscle to heal. The length of time depends on the extent of your injury and your own rate of healing.
Can a fall cause heart damage?
Blunt injuries to the heart can be caused by a motor vehicle crash, a fall from a height, or less often a direct blow. If the heart is severely injured, people often die before they can be treated.
Can tissue damage be repaired?
While a few types of tissue injury (such as minor paper cuts) can sometimes be healed in such a way that no permanent damage remains, most of our tissue repair consists of both regeneration and replacement.
How does tissue repair happen?
Tissue repair is a complex process involving the migration and proliferation of cells, the laying down of extracellular matrix, the generation of new blood vessels, and the remodeling of collagen to form a scar.
How important is tissue repair?
Tissue repair is an essential mechanism to maintain the integrity and function of the body in response to a variety of both acute and chronic injuries and disease states.
How do you know if your heart muscle is damaged?
Chest pain, chest tightness, chest pressure and chest discomfort (angina) Shortness of breath. Pain, numbness, weakness or coldness in your legs or arms if the blood vessels in those parts of your body are narrowed. Pain in the neck, jaw, throat, upper abdomen or back.
Can trauma cause heart problems?
Traumatic childhood increases lifelong risk for heart disease, early death. Exposure to trauma and other adverse experiences during childhood increases lifelong risk for cardiovascular disease and death, regardless of a person’s health during young adulthood, new research shows.
Can you bruise your lungs from falling?
A severe blow to the chest (as from a motor vehicle crash or fall) can bruise the lung. The bruised lung does not absorb oxygen properly. A large bruise can cause dangerously low levels of oxygen in the bloodstream. A severe pulmonary contusion is potentially life threatening.
