Heart
The heart is a major organ of the body that is found in the circulatory system. It pumps blood throughout the blood vessels. Questions related to the heart should be put here.
8,781 Questions
Why does death of heart muscle cells happen?
Many reasons - but most commonly due to a lack of oxygen secondary to blockage of a coronary artery.
How does the heart receive nourishment?
Heart tissue, as with any other cell in the body, gets its nutrients through the blood stream. The blood plasma holds nutrients, which diffuse into the cells through the cellular membrane, and erythrocytes supply oxygen to the cells.
Question:
The circulation that connects your heart, organs, and tissues and supplies oxygen to them is what?
Systemic circulation
What is the number one cause of heart problems?
Angina.
Myocardial infarction.
Cardiac failure.
Valvular heart disease.
Congenital heart disease.
Cardiomyopathies.
Why does the heart has valves?
Valves are the "doors" which allow the proper amount of blood into each ventricle of the heart so it does not "explode" or push too much into the body. When high blood pressure occurs the culprit can be a defective valve that is leaking or failing to open and close properly. Not many people have that type of high blood pressure. There are many types of high blood pressure which doctors can determine by listening to the valves in the heart or elsewhere.
What describes the next step after the blood has traveled from the heart to the toes?
The blood returns to the heart through veins.
Your heart pumps blood. It's part of the circulatory system.
As the blood moves away away from the heart does the blood pressure increase or decrese?
The pressure decreases as it moves away from the heart.
What are the names for the two different sets of heart valves?
Atrioventricular valves
Bicuspid Valve
Tricuspid valve
Pulmonary valve
Aortic valve
these are all the valves which are part of the heart.
Heart chamber that blood enters after passing through the tricuspid valve?
The tricuspid is an atrioventricular valve located on the right side of the heart, between the right atrium and right ventricle. It is called a tricuspid because it has three valves. The blood flows towards the right.
What are the upper chambers of the heart and their function?
right and left atrium. they collect and hold blood before sending them into the ventricles where they are pumped to all parts of the body.
right and left atrium. they collect and hold blood before sending them into the ventricles where they are pumped away from the heart.
right and left atrium. they collect and hold blood before sending them into the ventricles where they are pumped to all parts of the body.
How would the thickened muscles on the left ventricle affect the function of the heart?
If the left ventricle is weak, it causes the volume to back up. The increase volume, over time, will result in ventricular dilation.
What is the Difference between top two heart chambers from the bottom?
The difference between the two sides of the heart starts with their different functions. The larger, more-muscular left side has the job of pumping blood all over the body to take oxygen and nutrients to the body's tissues. The smaller, less-powerful right side is responsible for pumping blood only to the lungs. The blood in the left side of the heart has a higher oxygen content because it has just returned from the lungs. Conversely, the blood in the right side of the heart has a lower oxygen content because it just returned from delivering that oxygen to all the tissues of the body. The body is also known for life and life is very important because of DICKS
What medical term means abnormally slow heart rate?
No, that would be called tachycardia. Bradycardia is an abnormally slow heartbeat.
What is the flow of blood between the heart and lungs called?
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.
The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
What difference atria and ventricles fetal pig?
the difference between the ventricles and the atria is that the ventricles are thicker
Which cardiac structure control blood flow to the heart?
The semilunar valves control the flow of blood from the heart. The aortic semilunar valve controls the flow of blood from the left ventricle to the aorta, and the pulmonary semilunar valve controls the flow of blood from the right ventricle to the pulmonary artery.
Pulmonary valve
How can you influence your heart rate consciously?
By properly learned breathing exercises taught to you by a professional ONLY! People who suffer from anxiety can learn to control their breathing if they hyperventilate. Speak to your doctor and find a professional who can teach you to control rapid breathing.
Is rheumatic heart disease contagious?
Unfortunately, once you have rheumatic heart disease, the damage has been done and there is no cure.
Fortunately, Rheumatic heart disease is pretty uncommon in recent years.
If you are having effects from the damage done to your heart valves, such as heart failure or anemia from destruction of red blood cells, you may need to have a valve replacement.

Trace blood flow from heart to spleen?
Aortic arch to descending thoracic aorta to abdominal aorta to celiac trunk to splenic artery
Can you use an aed with a metal heart valve?
Yes. After first calling an ambulance, apply the suction pads and leads as directed. This allows the AED to monitor and record the heart action, and direct further if a shock is required. A shock will ONLY be delivered if the heart is in fibrilllation. If there is no pulse, CPR should be started until help arrives, regardless of if the AED tells you 'no shock required', this is because, as mentioned before, the AED is only effective in fibrillation.
