CIRCULATORY SYSTEM
serves to move blood to a site or sites where it can be oxygenated, and where wastes can be disposed. • The Circulatory System is the main transportation and cooling system for the body. • The circulatory system is how good and bad materials travel through our bodies.
The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce.
The Blood Vessels three types of blood vessels: Arteries ( red ) Veins ( blue ) Capillaries
Blood flow is the continuous running of blood in the cardiovascular system • Tracing the flow of blood through the heart isn't as simple as it may seem. The heart is a complex organ, using four chambers, four valves and multiple blood vessels to provide blood to the body. The flow through the heart is equally complex, with blood moving through the heart, then the lungs, before returning again to the heart.
AILMENTS OF CIRCULATORY SYSTEM
STROKE What Is a Stroke? Stroke is a medical emergency and the third leading cause of death in the U.S. It occurs when a blood vessel in the brain bursts or, more commonly, when a blockage develops. Without treatment, cells in the brain quickly begin to die. The result can be serious disability or death. If a loved one is having stroke symptoms, seek emergency medical attention without delay.
Stroke Symptoms Signs of a stroke may include: Sudden numbness or weakness of the body, especially on one side. Sudden vision changes in one or both eyes, or difficulty swallowing. Sudden, severe headache with unknown cause. Sudden problems with dizziness, walking, or balance
Stroke Test: Talk, Wave, Smile The F.A.S.T. test helps spot symptoms. It stands for: Face. Ask for a smile. Does one side droop? Arms. When raised, does one side drift down? Speech. Can the person repeat a simple sentence? Does he or she have trouble or slur words
Stroke: Time = Brain Damage Every second counts when seeking treatment for a stroke. When deprived of oxygen, brain cells begin dying within minutes. There are clot-busting drugs that can curb brain damage, but they have to be used within three hours of the initial stroke symptoms. Once brain tissue has died, the body parts controlled by that area won't work properly. This is why stroke is a top cause of long-term disability.
What Is Heart Disease? The topic of heart disease usually centers on heart attacks but there are many other problems that can compromise heart functions, injure the heart tissues, or cause heart disease. Most of the major problems include coronary artery disease, heart failure, arrhythmias, and cardiomyopathy. The following slides will present these heart problems and their warning signs
What Is a Heart Attack? A heart attack occurs when a coronary artery becomes blocked (usually in a coronary artery by a blood clot) resulting in loss of the blood supply to an area of heart tissue. Loss of the blood supply can quickly damage and kill heart tissue; quick treatments in the emergency department and/or the catheterization suite have reduced deaths from heart attacks in recent years but still more than a million
Symptoms of a Heart Attack Warning signs of a heart attack include the following: Chest pain Pain that may spread to the back, arms, neck, and jaw Shortness of breath Nausea, vomiting Rapid or irregular heartbeats
Inside a Heart Attack Plaque in coronary (and other) arteries maybe hard or firm on the outside but soft, mushy, and sticky on the inside. If the hard shell-like area cracks open, then blood components exposed to the sticky areas collect and can form a blood clot and quickly block most or all of the blood flow through the artery. The heart tissue downstream from the clot then suffers from lack of blood and becomes damaged or dies.
Call 911 When Symptoms Occur If you or an individual develop symptoms of a heart attack, do not delay getting medical help. Call 911. Do not drive yourself or others to a hospital as 911 emergency medical services (EMS) personnel can begin basic treatment immediately. Delaying care can result in increased heart damage or death
Atherosclerosis is a disease of the arteries in which fatty material is deposited in the vessel wall, resulting in narrowing and eventual impairment of blood flow. Severely restricted blood flow in the arteries to the heart muscle leads to symptoms such as chest pain. Atherosclerosis shows no symptoms until a complication occurs.
