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 are the differences between the 4 chamber of the heart?
the left & right atria also the left & right ventricle
Which is an example of a scientist using a physical model to describe a human heart?
You'll need to first find a pump that will mimic the human heart, then find the electric parts to keep it going. There might be clear alginate for the heart, or perhaps rubber. For that you'll need to search websites for art supplies or other warehouses that sellliquid rubber or alginate. Next you make form for the front and back halves of the hearts to coat with the rubber. Assemble the parts and see if it will do what you want.
This project will take a bit of time to complete the experiments and find the products you need to make this work. I admire your ambition.
Why is water important in all living organisms?
So that they dont die
- Water acts as a solvent to provide a liquid environment for biochemical reactions. Solid phase is too slow and gaseous phase is too fast for biochemical reactions.
- Water stays liquid at high temperatures (relatively compared to CH4 and NH3) and stays liquid over a wide range of temperatures. Higher temperatures and wider range of temperatures for liquid phase means that reactions can happen faster and under more diverse circumstances.
- Water dissolves polar compounds and does not dissolve nonpolar compounds. This is important for both biochemical reactions and crucial hydrophilic/hydrophobic interactions in protein folding.
- Water is an important reactant in certain biochemical reactions such as electrolysis reactions and the first step of the photosynthetic electron transport chain.
- Water has a high specific heat capacity to facilitate better maintenance of internal temperature and the usage of evaporation to cool down.
What does the heart do in the human body?
It delivers Oxygen to the brain and tissues and all the other organs in your body. Without a heart you would not BE ALIVe
And it gose BOOM BOOM PAWW
BOOM BOOM PAW
BOOM BOOM PAW
(AND IF YOUR SMOKE)
BOOM (BREATH) BOOM (BREATH) DIE!!
Describe the location and position of the heart in the thorax?
beneath your ribs slightly to left of the centre. Not near the bottom of your ribs under your breast / chest.. If you are in a quiet room, put your hand over your chest where i have said you heart is located and concentrate .. You can feel/hear it.
What does cardiac output do if heart rate increases?
because your muscles are working so much harder, they need more oxygen, and also produce more waste products. Your cardiac output increases so that the blood is pumped around the body faster to provide the oxygen required and remove any waste.
The correct sequence in the conduction system of the heart is?
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
Why do fit people's hearts beat more slowly than unfit people's hearts?
The heart doesn't have to work as heard to circulate blood throughout the body because the arteries (pathway for blood) are clearer and there is less blockage. Unfit people usually have arteriosclerosis (hardening of the arteries) and atherosclerosis (accumulation of plaque); both of these make it harder for blood to move about the body, forcing the heart to work harder by pumping faster.
Why are there two separate sides to the heart?
the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.
aspirin is used to relieve many kind of minor aches and pains _headache ..some people take aspirin daily to reduce the risk of strok , heart attack.
Which organ is the first recipient of oxygen-rich blood from the heart?
well the first port of call is the lungs to exchange co2 for o2 and then back to the heart so obviously the heart// peace
obviously its the heart. what is the first to receive from the heart the question ask
What side of the heart receives blood from the lungs?
It is left auricle in heart which receives blood from the lung.
WOG" is simply defined as water, oil or gas and traditionally accepted as a catch all for ambient temperature fluids
How does the pump action of the heart work?
The pump of the heart is blood cells going through the heart to get oxygen from the lungs.
What is the function and roles of the right atrium?
The left ventricle is where the blood that is oxygenated is pumped from into the aorta. The atrium is the above the left ventricle, and the bicuspid valve (which controls blood flow) has a place where there is a more controlled amount of blood going into the aorta.
What is the sound of your heart beating?
The atria and ventricles work together, alternately contracting and relaxing to pump blood through your heart. The electrical system of your heart is the power source that makes this possible. Your heartbeat is triggered by electrical impulses that travel down a special pathway through the heart.
Is it normal to actually feel your heart beating?
Your heart will pump more quickly after physical activity, or when one is under stress or anxiety.
The blood flow quickens to transport oxygen from the lungs to parts of the body faster.
