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.

What carries blood between the heart and body?
The heart pumps it around the body through arteries and it the blood returns to the heart via the veins.
Muscle tissues in order to pump the blood, and fibrous tissue that are made up of the valves.
your heart tissue is made of cardiovascilar tissue. i think that's how you spell it, your heart is the only musule with that tissue. but whats hard for me to believe is you didnt learn that in eitheer 3rd, 4th, or 5th grade.
How will you compare the heart pump model to human heart?
The heart pump model can be compared to the human heart by examining its structure, function, and efficiency in circulating blood. Both systems utilize chambers and valves to facilitate blood flow, but the heart pump model may lack the biological complexities and regulatory mechanisms present in the human heart, such as hormonal control and neural regulation. Additionally, the heart pump model can be evaluated on its ability to mimic the cardiac output and pressure dynamics of the human heart under various conditions. Overall, while the model provides valuable insights, it cannot fully replicate the intricacies of human cardiac physiology.
Is dizziness and nausea signs of an impending heart attack?
Yes sweating and nausea and dizziness can be a sign of a stroke or heart problem in people . Here are some sites that can help you out with this www.webmd.com/heart-disease/guide/heart-disease-symptoms
Why is the walls of the lower chambers in the heart thicker than the walls of the upper chambers?
Because the net weight of the fluid in the blood is bigger, because the bigger size of the lower chambers (ventricles) allows more blood to accumulate in there, thus causing the need for thicker walls
What is the circulation called when it travels from the heart to the lungs and back?
Pulmonary circulation is the movement of blood from the heart, to the lungs, and back.
When viewing a dissected heart it is easy to visually discern the right and left ventricles by?
The walls of the left ventricle are 3 times as thick as those of the right ventricle, and its cavity is basically circular. The right ventricle cavity is crescent shaped and wraps around the left ventricle, the way a hand would loosely grasp a clenched fist.
What are the four divisions in the human heart?
the upper and lower part
upper part- recives unoxygnated blood and release the oxygenated blood to the whole body system.
lower part- or pumping station it recive the unoxygnated blood and the lower part will make it oxygenated blood.
How many chambers are there in a mammal's heart what are they?
NO they do not. They have four chambered hearts.
What is more important Heart or Brian?
Both are very important.
DETAILS-THE HEART:Some would say the heart is more important because it pumps blood to all parts of the body, including the brain. Without the blood in the brain, the brain would not be able to control involuntary activities such as heart beat. Basically, the brain needs the heart to pump blood to it.
THE BRAIN:
There is one part of the brain that controls involuntary activities such as heart beat. (The name of that part is the medulla) Without the medulla, the heart would never be able to pump blood to other parts of the body. Even though, you still need the heart to pump blood to the brain to let it function and control.
OPINION-In my opinion truly, I think the heart is the most important because of the latest technology, machines are able to act like medullas and control heart beating. But, in order to live a wonderful life, both organs the heart & the brain are needed. :) DEFINITIONS-Involuntary activities- actions that the body cannot control, it just happens.(examples: breathing, digesting, heart beat.)
Medulla- a part of the brain that connects the spinal cord to the brain. It controls involuntary activities.
(located on the bottom of the brain and is the smallest part of the brain.)
What is the relationship between coronary artery disease and a heart attack?
atherosclerosis is a condition where plaque builds up in your arteries. This can narrow the artery, reducing blood flow and oxygen perfusion. In the case of the coronary system this reduced perfusion can lead to chest pain or a heart attack. this condition can be worsened if the plaque build up ruptured. the body will respond to this by building a clot around the area, further reducing blood flow and oxygen. worst case scenario this will lead to an acute myocardial (AMI) causing cell death to cardiac muscle.
How do the valves between the atria and ventricles control the direction of blood flow?
The heart contains valves to prevent the backflow of blood. The right half of the heart has a "Triscupid Valve" and the left half of the heart has a "Biscupid Valve".
Is the heart the only muscle and organ that pumps blood?
I'm afraid I have no idea what you're asking, but the heart (an organ) is made of cardiac muscle (which means "heart" muscle). As far as I know, no other muscles are considered "organs," and I'm not even sure the heart isn't simply considered a muscle.
Why human heart is divided into four chamber?
On one side is oxygenated blood, and on the other is blood that does not contain oxygen. It is divided into two because if those two different types of blood mix, your brain can never get enough oxygen to function properly, leading to mental stupidity.. It is really important that those two types of blood do not mix.
The left side is thicker because it has to pump blood to the entire body, where as the right side only has to deliver blood to the lungs. Your body is actually large compared to your heart. Your heart is only the size of your fist. Ask me if you have any questions :)
What are the 2 chambers on top of your heart called?
The two chambers on top of the heart are called the atria. There is a right atrium and a left atrium, which receive blood returning to the heart from the body and lungs, respectively. The right atrium collects deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs.
What type of tissue is in the heart?
Cardiac tissues, smooth muscle, endothelial cells.
Cardiac Muscle found in the hearts chambers right and left atrium and riht and left ventricle. This tissue perform the pumping of the heart.
Smooth muscle tissues provide stability and flexibility so that the large arteries can contract and expand.
Edothelial cells line the chambers and vessels. They stop blood components from moving to the muscle and help prevent clotting.
How do you get painful gas in your body out?
It depends how young or old your child is, but there are a number of things which can help - the two most common of these being Peppermint tea (well sweetened), and "gripe water".
Gripe water is intended for babies and children up to about 18 months, to help ease the kinds of pain associated with the stomach and with gas, while Peppermint tea helps with older children. Peppermint is well known to calm and settle the stomach, as well as having an assisting effect in bringing up and dispersing wind.
In the absence of Peppermint tea, giving your child a Peppermint to suck (something with real Peppermint oil in it, like Altoids) makes a good substitute.
