Heart

Blood flows into the right atrium from the vena cava. It then is pumped to the right ventricle, which pumps the blood to the lungs via the pulmonary arterial system. In the lungs, the blood dumps CO2 and picks up O2 from capillaries running next to the alveoli of the lungs. Then, the returning blood enters the left atrium from the pulmonary veins, where it is pumped to the left ventricle. From there, the blood leaves the heart through the aorta to be distributed throughout the body.
Blood enters the heart through the superior and inferior venae cavae into the right atrium. This blood then flows through the right atrioventricular valve to the right ventricle. The right ventricle contraction opens the pulmonary valve and blood flows into the pulmonary trunk. The pulmonary arteries allow oxygen to be put into the blood, and carbon dioxide to be taken out. The blood then flows from the lungs through the pulmonary veins to the left atrium. It then flows through the left atrioventricular valve into the left ventricle. The contraction of the left ventricle opens the aortic valve. The blood then flows into the aortic valve to the ascending aorta and goes through the body to deliver oxygen to organs. The carbon dioxide-rich blood returns to the heart by means of the venae cavae. Contraction of the heart happens on both sides at the same time.

The left atrium is like a "turbocharger" for the left ventricle of the heart. It fills with oxygenated blood from the lungs, then contracts to pump the blood into the left ventricle. Here, the ventricle then contracts to pump the oxygenated blood all around your body.

Parts:

Pulmonary veins(left and right)

Superior vena cava

Inferior vena cava

Right atrium(auricle)

right ventricle

Pulmonary Arteries(left and right)

Left atrium(auricle)

Right ventricle

Left ventricle

semi-lunar valve

bicuspid valve

Function:

To pump blood.

Right side pumps to the lungs & the left side pumps to the body.

Absence from someone you love does, in fact, make the heart grow stronger. Absence in this sense can mean either or both distance and time. When an individual is away from another they care deeply for, or have good types of feelings about, they are more likely to feel those caring and good feelings more-so then before the person was away.

This word can be broken down into two parts that will reveal the answer to your question. Myo is the medical term for muscle and cardio is the medical term for heart. Therefore, your answer would be the muscle that is the heart.

There are two chambers at the top. There is one above each ventricle. They have been given the name atrium which means a room that leads to a larger room. The one on the right side of the heart is called the right atrium and the other is the left atrium. The ventricles are called the left and right ventricles.

The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.

Cardiac is the adjective that denotes "heart."

the chambers help the respiration by a flowinf the blood to go out and in so the blood has guide on where it is going. BY: Pocholo thank you for reading

In fact, we have 2 hearts, one beside another.

Its like a dual pump in other words, one pumps deoxygenated blood, while one pumps oxygenated blood.

Taking the two formulas: Cardiac Output = Heart rate x Stroke Volume Blood Pressure = Cardiac Output x Peripheral Resistance When Blood pressure drops, either cardiac output (Heart rate or Stroke Volume) has to increase, or peripheral resistance (Aterioles Vasconstriction) has to increase. When Blood pressure drops, this is detected by baroreceptors in the carotid bodies and arch of the aorta, these send signals to the cardio vascular centre within the Medulla, which sends signals back to the heart to increase the heart rate and force of contraction. The medulla also sends signals to arterioles to constrict and therefore raise blood pressure. Hope this helps Colin

There doesn't appear to be any clear answer to this question. The only thing that everyone agrees on is that implants don't last forever. Some people recommend for safety having breast augmentation redone in as little as 5 years. Others think that 10 years should be sufficient if there are no known complications.

• How many gallons of blood does an adult human heart pump?

• How long does it take for your heart to pump blood through your body?

• What is the heart made of?

• Where does the heart send used blood?

• What body system does the heart belong to?

Oxygenated blood will pass through the bi-cuspid valve, located in the left ventricle, and the semi-lunar valve, located at the entrance to the aorta.

I would have to say; depending if it's the left or right side. Left side it would be the aortic valve and the right side would be the pulmonary valve.

You are very healthy and your blood is moving well.

The aorta is pumping too deeply, you should see a doctor immediately!!

Most human hearts are about the size of a human fist, some a little larger, are located just behind the sternum to about the left nipple. If you follow the curve of your chest muscle from the sternum to the left about 3.5 inches and level with both nipples (on men), you will be over the center of the heart. Between the 4th and 5th ribs at this point is the easiest path to the heart. Some skinny people can see their heart beat between these ribs.

Answer:The sternum protects your heart=and its in the middle of your rib cage=

the bottom/point of the heart is called the apex

Well, both birds and mammals have four heart chambers. So, there is your answer!

An elevated heart and respiratory rate helps the body Êto gain Êsufficient oxygen and energy.Whereas, stimulating Êsweating Êbefore a race is important as it Êmake the sweat gland more Êactive.

depends on the adults size of hand

Closure of the two atrioventricular valves, specifically the tricuspid and mitral valves.

Lotuses are symbols of purity and 'spontaneous' generation and hence symbolize divine birth. According to the Lalitavistara, 'the spirit of the best of men is spotless, like the new lotus in the [muddy] water which does not adhere to it', and, according to esoteric Buddhism, the heart of the beings is like an unopened lotus: when the virtues of the Buddha develop therein the lotus blossoms. This is why the Buddha sits on a lotus in bloom. In Tantrism, it is the symbol of the feminine principle. The lotuses are usually differentiated by their colour and grouping, in three or five flowers, which may or may not be combined with leaves. White lotus This symbolizes Bodhi, the state of total mental purity and spiritual perfection, and the pacification of our nature. It generally has eight petals corresponding to the Noble Eightfold Path of the Good Law. It is the lotus found at the heart of the Garbhadhatu Mandala, being the womb or embryo of the world. It is characteristic of the esoteric sects, and the lotus of the Buddhas. Red lotus This symbolizes the original nature of the heart (hrdaya). It is the lotus of love, compassion, passion, activity and all the qualities of the heart. It is the lotus of Avalokitesvara. Blue lotus This is the symbol of the victory of the spirit over the senses, of intelligence and wisdom, of knowledge. It is always represented as a partially opened bud, and (unlike the red lotus) its centre is never seen. It is the lotus of Manjusri, and also one of the attributes of Prajnaparamita, the embodiment of the 'perfection of wisdom'. Pink lotus This is the supreme lotus, generally reserved for the highest deity, sometimes confused with the white lotus it is the lotus of the historical Buddha. Purple lotus This is the mystic lotus, represented only in images belonging to a few esoteric sects. The flowers may be in full bloom and reveal their heart, or in a bud. They may be supported by a simple stem, a triple stem (symbolizing the three divisions of Garbhadhatu: Vairocana, lotus and vajra), or a quintuple stem (symbolizing the Five Knowledges of Vajradhatu). The eight petals represent the Noble Eightfold Path and the eight principal acolyte deities of the central deity on the mandalas. The flowers may also be depicted presented in a cup or on a tray, as a symbol of homage. from http://www.buddhanet.net/e-learning/history/b_lotus.htm
