What will happen if one part of the circulatory system fails to function properly?
What will happen if one part of the circulatory system fails to function properly?
High blood pressure can lead to stroke, loss of vision, heart failure, heart attack, kidney disease, and reduced sexual function. A stroke can happen when one of the vessels that lead to the brain either becomes blocked by a blood clot or bursts. This stops blood flow and prevents oxygen from getting to the brain.
What happens to the blood in the rest of the body?
Two types of blood vessels carry blood throughout our bodies: Arteries carry oxygenated blood (blood that has gotten oxygen from the lungs) from the heart to the rest of the body. Blood then travels through veins back to the heart and lungs, so it can get more oxygen to send back to the body via the arteries.
What is one disease that affects the circulatory system?
Atherosclerosis, also known as hardening of the arteries, occurs when plaque builds up on the walls of your arteries and eventually blocks blood flow. Plaque is made of cholesterol, fat, and calcium. Coronary artery disease indicates that the plaque buildup in your arteries has caused the arteries to narrow and harden.
Which condition produces heart attack like symptoms but does not damage the heart muscle?
In unstable angina, blood work that assesses for damage to the heart muscle is negative, indicating no heart attack (yet). Generally, at rest, there is still some blood flow beyond a severe blockage, and so there has not been damage to the heart.
Can doctors tell if you had a heart attack?
If your doctor thinks you may have had one, he or she may order imaging tests. These could include an electrocardiogram ( ECG or EKG ), which is a special ultrasound, or a CT scan or MRI of your heart. These tests can show if your heart muscle has been damaged, signaling that you’ve had a heart attack.
Can you have a heart attack and feel fine?
With SMI, you may feel discomfort in the center of the chest and not a sharp pain on the left side of the chest, which many people associate with a heart attack. “People can even feel completely normal during an SMI and afterward, too, which further adds to the chance of missing the warning signs,” says Dr. Plutzky.
Can EKG show old heart attack?
An ECG can show evidence of a previous heart attack or one that’s in progress. The patterns on the ECG may indicate which part of your heart has been damaged, as well as the extent of the damage. Inadequate blood and oxygen supply to the heart.
