the larger the force pushing the two surfaces together the stronger the microwelds will be , because more of the surface bumps will come into contact , to move one surface over an other , a force must be applied to break the microwelds .
The energy is from the force of gravity pushing the object down the hill, without gravity the object would not fall. The object would remain in place until acted upon by an outside force.
no.
cuz they come from your ass duhhhhhhhhh
When they jump, they come down.
The heart has two pumps inside of it and each has two chambers and two valves. The left side of the heart has the biggest chambers, and the one that pumps the blood to your body is called the left ventricle, When it contracts (squeezes together), the first valve closes shut (that's the "lupp" sound of a heart beat) and the contraction pushes the blood up past the second valve and into aorta, which is the main artery that distributes the blood to the regular arteries that carry the blood throughout the body. When the blood goes into the aorta, the second valve shuts so the blood doesn't go backwards into the heart and that is the "dubb" sound of a heart beat.
your heart!your attiliries carry blood from the heart and your veins carry blood to your heart because they ran out of "food"
yes if i doesnt come out ull die
No. The heart is an organ that pumps blood.
heart valves opening and closing
this is two step process.in the first process blood go from the heart and in the second step blood come into the heart for clean. when it goes from the heart it is cleaned blood,but when it returns it become dirty and our heart performs as a filter and it cleans our blood. this is the chemistry of blood, hopefully you would like it.
yes
No blood does not come from the brain. It comes from the heart. It is pumped and some is sent to the brain and other parts of the body.
If you are asking where blood cells are "made," they are made in bone marrow.
Oxygenated blood is carried by the pulmonary vein. This vein transports blood from the lungs to the heart.
When a cat let's it's claws come out, it puts force on its pads pushing out the claws. When that force is stopped, the claws retract.
Carries oxygenated blood from the lungs to the left atria of the heart. Brings blood from the lungs to the heart.
