How does the heart work brief answer?
The heart pumps blood around the body to ensure your body has enough blood in your body otherwise you can die instantly. The heart is an automated, muscular machine that uses muscles to pump blood. The heart has 4 chambers and valves. The top chambers pull blood into the heart, and the lower chambers push it out. The valves keep the blood moving in only one direction so the heart can work. If the blood tries to go both ways, pumping doesn't occur. The natural pacemaker that is a branch of the vagus nerve is what slows down the heart and regulates the speed. One side of the heart pulls oxygenated blood from the lungs and send it to the body starting with the aorta (the largest artery). The other side of the heart pulls the stale blood from the vena cava (the largest vein) and sends it to the lungs.
Which term refers to the force exerted as the heart pumps from the left ventricle into the arteries and out into the body?
The atria Actually, it is the contractions (squeezing) of the ventricles (the lower parts of the heart), not the atria (the upper parts), that do the pumping. That's why the lower part of the heart is larger, and the muscular walls are thicker. The atria receive the blood from the body and pump it down into the ventricles.
How does the blood from the lower parts of your body enter the heart?
Through the right ventricle =D
How does the heart helps in the distribution of the blood throughout the body?
The heart does not just "help"- it is the primary force to push blood through the arteries to all parts of the body. It is a pump.
What lower chambers of the heart pump out blood of the organ?
The left ventricle. Blood from the body comes into the right atrium goes into the right ventricle and is then pumped to the lung comes back to the left atrium and then left ventricle to the aorta to the body.
What force pulls the blood to the lower part of the body?
magnetism
What force pulls the body to the lower part of the body?
Gravity.
What force fulls the blood to the lower parts of the body?
Your heart pumps blood to all parts of the body.
What is the force that pulls the freely falling body towards the earth is called?
Gravitational Force
How is weight a force?
because it is experienced by pull of earth.weight of a body is equal to force by which earth pulls body towards its centre
When do you experience redouts?
A redout occurs when the body experiences a negative g-force that causes a blood flow from the lower parts of the body to the head. It is the opposite effect of a greyout.
What brings blood from the lower part of the body to the heart?
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
What Sends blood to heart from lower body?
The inferior vena cava is the large vein carrying blood back from the lower body.
What supplys blood to the lower body?
delete and rephrase this odd question please... to answer THIS question... the same as the top of the body
What is force on the moon?
The Earth pulls on the Moon, and the Moon pulls on the Earth. The Sun pulls on the Moon, and the Moon pulls on the Sun. Mars pulls on the Moon (ever so slightly) and the Moon pulls on Mars. Your body pulls on the Moon (hardly measurable, but it does) and the Moon pulls on your body. The Moon and Sun and Earth's gravity pull (and push) Earth's oceans, and the ocean "tides" are the results.
Why the pressure in blood vessels pulmonary vein and inferior vena cava is less than the aorta and pulmonary artery?
In a healthy person, the blood pressure in the arteries of the lungs is usually lower than the pressure of the blood in the rest of the body because the blood is pumped from the weaker right side of the heart (a shorter distance from the heart) into the lungs.
Why is the blood pressure lower in lung capillaries than body capillaries?
Because if blood pressure in lung capillaries was as high as it is in body capillaries, the hydrostatic pressure caused by this blood pressure would force blood plasma out of the capillaries into intracellular spaces (as is done in body capillaries) or into the alveoli. This would reduce the efficiency of gas exchange.
