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
What is the central thoracic region that contains the heart?
The heart is a thoracic, not abdominal, organ. It is found in the mediastinum.
What is the ventricular septum?
That portion of the heart wall that divides the right and left ventricles
Why do children's heart rates inncrease as they get older?
That is a very good question! I do not know the exact answer. Birds like sparrows have got very fast heart beats. The heart rate of the large animals like elephant is very slow. So it looks that the heart rate is proportional to the surface area of the body. Smaller the size, more the surface area. I am also curious to know the exact answer of this question.
any infection that gets in the blood stream can also get in the heart causing infection.
What happens to the blood in the right ventricle?
blood in the right ventricle goes right to the lungs to be oxygenated then the blood goes to the left atria then left ventricle then throughout the body the back to right atria then right ventricle
What does it mean when blood flows backwards in heart?
It could mean that you have Pulmonary Arterial Hypetension.
What causes your heart rate to increase during exercise?
Exertion on the body causes the need for blood to be circulated at a faster rate - thus the heart rate increases to make this happen. This can be a good thing.
Before exercise your heart rate might increase in anticipation of the exercise.
What will happen with the heart if any of the ventricles or atrium is injured?
If the heart is injured or diseased, the organism is likely to die without medical intervention because the heart pumps blood to all parts of the body and without blood none of the organs will work.
If minor injury then it will heal, during which period the animal will have a reduced capacity for work.
If major, it will die.
What bones are around the heart?
The sternum, ribs 3-6 (3 on each side) and vertebra T 3-6 for a total of 10.
What is different about the heart and lungs?
The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen. This occurs in the lungs and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide.
They work hand in hand to provide the tissues of the body with oxygen. The respiratory system oxygenates the blood and the circulatory system sends it to the rest of the body.
The heart works as a pump basically moving blood through the entire system to nourish the body and deliver oxygen to tissue. The heart pumps blood through the capillary vessels around the lungs so that red blood cells can pick up oxygen that has been transported across the alveolar membranes in the lungs. Maybe that a little over simplified but thats the basic idea.
Your lungs send oxygen to your heart so the blood can have oxygen in it
When you inhale, oxygen rushes into your lungs which is diffused into your bloodstream through alveoli located on the bronchioles. The heart pumps oxygenated blood throughout your body. All cells absorb oxygen which they need to live. Blood becomes deoxygenated and continues to be pumped by heart back to lungs. Deoxygenated blood also contains waste products of cells which are rid from your body when you exhale.
The lungs do not affect how the blood flows through the arteries and veins, it simply provides oxygen to the hemoglobin in the blood so that it may be carried to your organs. The heart is responsible for making sure that blood is flowing through the body's arteries and veins because it pumps it throughout the body.
The lungs pull oxygen into the body. The heart oxygenates the blood cells by pumping the blood to the lungs. Together with the arterial and venous system, the body is oxygenated.
the lungs inhale oxygen which goes to your avioli that lets the Oxygen seep into the blood and takes out the carbon dioxide so your body can function.
The heart pumps oxygen poor blood to the lungs, where the lungs infuse oxygen into the blood, and then the heart distributes the oxygen rich blood throughout the body supplying your muscles with oxygen.
The cardiovascular system works with the respiratory system to ensure that all living cells receive a constant supply of oxygen - the cardiovascular system pumps the oxygen around the body and the respiratory system allows the oxygen to enter the blood from inhaled air.
Where is the lateral ventricle located?
Lateral ventricle is located in the brain (in telencephalon). Its central part lies in parietal lobe, but its so-called 'horns' - cornu anterius, posterius and inferior extend into the frontal, occipital and temporal lobes, respectively.
the precordium is the external suface of the body overlying the heart and stomach...i still don't know what it means sorryz.
What is the name of the space in between the lungs where the heart is found?
this is the thoracic cavity, the space between the neck and the abdomen, this contains the lungs, heart & the main artery called the aorta, the lungs are covered by a membrane called the pleura which holds the lungs in situ and is the area affected by pleurisy, if air or gasses are allowed to permeate this area outside the lungs the vacuum that enables breathing is compromised and a collapsed lung can occur.
Cup both of your hands in front of you and put the little finger edges against each other, and then imagine the heart taking up that space; that is the average size of the heart, depending on the size of the person.
What are complex carbohydrates that aids elimination and may help prevent heart disease and cancer?
Dietary Fiber is the complex carbohydrate that aids elimination and may help prevent heart disease.
Why does the heart beat faster in stress?
Your heart beats fast because when your brain gets a sudden fright it contracts all muscles and that uses oxygen and it also contracts the heart and so the heart needs to pump blood around more often so the muscles can continue to react in the state of emergency in rapid speed. I hope this answers your question.
What is the difference between a resting heart rate and a active heart rate?
The difference between a person's resting and target heart rate reflects the amount of work the heart must do to meet the increased demands of the body when exercising.
What makes up the pulmonary circuit?
The circulation of venous blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart.
Is there a Heart and lung bill for law enforcement officers Florida?
Yes there is but Law Enforcement Officers are not taking advantage of it..They can get all their heart related drugs paid for by the state Of Florida and most don't know or do not not take advantage of this new law..
What does the heart muscle do in between beats?
Your heart is still a muscle, and thus forth needs to rest in between beats. Rest.
What would happen if a valve in the heart stopped working properly?
One result could be heart failure, which despite the sound of it is not an acute sudden and complete termination of heart function. If the 'left heart' fails, the part of the heart that specializes in moving blood from the lungs to the body, then there is usually a build-up over time of fluid in the lungs. If the 'right heart' fails, the part of the heart that moves blood from the body to the lungs for oxygenation, then there may be edema (swelling) in the body's extremities.
What is the maximum blood volume contained in the ventricles?
The maximum for both ventricles in an adult male is 70ml.
What is The function of left and right bundle branches?
The right bundle carries nerve impulses that cause contraction of the right ventricle (the lower chamber of the heart) and the left bundle carries nerve impulses that cause contraction of the left ventricle.
Why men's heart are bigger than women?
it depends wither they are active as athletic people have larger hearts due to the amount of blood being pumped around - men do generally have larger hearts as they are bigger then women it depends wither they are active as athletic people have larger hearts due to the amount of blood being pumped around - men do generally have larger hearts as they are bigger then women it depends wither they are active as athletic people have larger hearts due to the amount of blood being pumped around - men do generally have larger hearts as they are bigger then women
