That would depend on the decision. If it is an intilectual questions (ie. who to vote for) make it with your brain. If it's a purly passion decidion (ie. who to go to prom with) make it with your heart. But be sure that you catigorize the decision correctly. A majority of decisions a person makes can be made with either, but should be made with a combination of both. Some decisions have much greater consiquesnces than may appear at first so think them through.

If we throw 1000000 out of our calculations (this is okay because it doesn't have any nines in it) then we're left with all the numbers with 6 or less digits.

There are 10 choices for each digit. If the 100000's digit is 9, then there are 105=10000 ways to choose the remaining digits, so there are 10000 numbers that have 9 in the 100000s place. Similarly, there are 10000 numbers that have 9 in the 10000s place, 10000 numbers with 9 in the 1000s place, and so on. There are 6 different places 9 could be in, so the digit 9 is used 10000*6 or 60000 times.

Improved... well your missing a zero in your answer.... the total amount of 9's used should be 600 000 , not 60 000 because already in the hundred thousands digit 9 is being used 100 000 times becasue from 900 000- 999 999, the number nine is being used atleast

100 000 times so already your answer is wrong. And if you did you method corectly, it should be the same for every other digit, which means the answer will be that 9 will appear 600 000 times between 1 and 1 000 000. Correct me if im wrong, but im pretty sure that that is the answer.

about 1 to 2 watt, depending size of te individuals.

it doesnt technically beat, its full of nerve endings which cause the muscles in the heart to twitch making it look lyk its beatin x

The closing of the mitral and tricuspid valves produces the S1 sound, followed by the closing of the aortic and pulmonic valves, which produce the S2 sound. In sequence, it sounds like "lub-DUB, lub-DUB, lub-DUB".

To move the valve down as the camshaft rotates.

The heart is the prime mover in the circulatory system. And the circulatory system is how all living tissue in our body is carried food and oxygen, and how all waste and carbon dioxide is carried off. idiot it doesent make sence

Yeah! Cuz the roots collect water and distribute nutrients to the tree! ;)

right coronary artery

Proprioceptors, stretch-reflex receptors.

frogs heart has five chambers namely.

1-Sinus Venosus =Thin walled

2-Right auricle =Thin walled

3-Left auricle =Thin walled

4-Ventricle =Thin walled and muscular

5-Truncus arteriosus =Tabular thick walled

The cardiovascular perfusionist is who operates the heart-lung bypass machine during open heart surgery.

This wall separates the ventricles, which are the lower two heart chambers and the major pumping chambers of the heart. It is important that full separation is achieved and each ventricle functions without any type of blood communication with the other.

bitter heart means that you are getting angry or uncomfortable.

Bitter is an adjective.

BITTER ex: soup

The largest force in the heart is generated by the left ventricle, which has the task of pumping blood throughout the rest of the body, unlike the right ventricle which only has to pump blood the short trip through the lungs.

The heart is about the size on a person's fist. It is made up of specialised cardiac muscle and is known as 'double pump' because each side of the heart works separately, the right side of the heart pumps blood from your heart to your lungs through the pulmonary artery. The left side of your heart pumps blood to other parts of your body through the aorta. The heart has four chambers a right atrium and ventricle and a left atrium and ventricle it also has special valves that make sure the blood is always pumped in the right direction. The muscle of the heart is specialised because it needs to be strong enough to beat everyday for a life time .The heart also has its own pacemaker, which sends electrical impulses to make sure the heart maintains a regular heart beat. The heart is made up of cardiac muscles.it has 4 chambers which separated by a partition called septum. The upper 2 chamber called atria and lower 2 are called ventricles. The left atrium is connected to left ventricles through a valve. The roght atrium is connected to the right ventricle through another valve. These valves prevent the backflow of of blood into atria when the ventricles contract to pump out the blood of the heart to the rest of the body. Ventricles have to pump blood into various organs with high pressure , so they have thicker walls than atria. The atries , veins and capillaries are a kind of thin pipes through which blood flows in the body . Through pulmonary veins oxygen reaches blood comes to left atrium from the lungs and then transferred in the left ventricle. Left ventricle contract and blood is pumped out to the whole body . Deoxygenated blood comes to right atrium from the whole body then it comes in the right ventricles and sent to the lungs by pulmonary artery.

Quite possible. It also depends on how long you have known this person and how long he/she has been a part of your life. I don't understand how you don't know if it is love or not when you claim that you can't live without them. Only your heart can tell you if it feels like it's love or not. It's love if you can die for them or die with them because you can't live without them and possibly fantasize about others because of lust, after you heart has been broken, but it's not love if you don't know if it's love or not, maybe due to because it's your first time in falling for someone. So really, it's up to you to decide on how you really feel about them and how much feelings you have for them. But anyways, I think maybe you should give up on relationships for now because it seems as if you're not ready for love just yet, since you don't know how love and lust feels like, and you might as well forget about relationships until you think that and feel like you're possibly in love.

Transmissions from the Satellite Heart was created on 1993-06-22.

A four chambered heart establishes two distinctly separate circulatory pathways. Pulmonary circulation carries blood from the heart to the lungs and back. Systemic circulation carries blood from the heart to all other areas of the body and back. To have separation of these pathways by a second ventricle insures no mixing of oxygenated blood (from the lungs) with de-oxygenated blood (from all other parts of the body). Pumping blood to all parts of the body with a higher concentration of oxygen would enable tissue to produce more energy which could sustain a higher level of activity and allow warm blooded animals to evolve (birds and mammals).
