Heart

No. A hiccup is just a breathing spasm. The heart is not affected under normal conditions.

Actually, the exchange of oxygen for CO2 happens in the lungs. The heart pumps the blood through the system.

However emotional we are, the brain rules all our activities and bodily functions as well as our emotions. Hope this helps and good luck to you!

It pumps the blood quicker to get more oxygen to the muscles...

an artificial hearts can last from about 5 months to about 5 years

upper left and right atria and lower left and right ventricles. Atria are divided by interatrial septum&ventricles by interventricular septum.Both Atria&Ventricles are separated by tricuspid&bicuspid valves

be honest the way you touch it the heart can damage

no, never, unless it goes into cardiac arrest or you are dead.

There is no "blue blood," only red blood. Deoxygenated blood is dark red and oxygenated blood is bright red. Deoxygenated blood (dark red) picks up oxygen at the lungs in the alveoli. The high concentration of oxygen in the lung cavities diffuse into the low concentration of oxygen in the blood. The oxygen binds to the hemoglobin and becomes "oxygenated," and continues to the systemic circuit.

Normally a human heart beats 72 times in a minute. 60 to 80 beats are normal beats/minute in the human body.

cardiac cells are specialized muscle cells

brain cells are nerve cells

The heart is divided into two sides each side is divided again into two chambers the atrium upper chamber and ventricle lower chamber blood vessels veins carry blood to the heart from the rest of the body this blood carries carbon dioxide and cellular waste products the blood goes into the right atrium and then to the right ventricle where it is then pumped to the lungs to dispose of wastes and receive a fresh oxygen supply from the lungs the blood returns to the heart It returns to the left atrium and then to the left ventricle the blood is then pumped out of the heart by the left ventricle into the aorta the left ventricle is the chamber of the heart that is responsible for pumping blood to all parts of the body the aorta sends this blood to small arteries, which carry the oxygen-rich blood to the rest of the body. information obtained from http://www.besthearthealth.com/about.HTML

The pulmonary valve, one of the semilunar valve, permits blood flow from the right ventricle. From there, the blood goes to the pulmonary artery, and then to the lungs.

the weight of the human heart is 300 gram in adult males and 250 grams in adult females

Left atrium via the pulmonary veins from the lungs.

Your Brain is like the harddrive on your computer. It controls all your body functions including breathing, movement, awareness, cognitive abilities, heart function, nerve and muscle function etc. The only way a heart still beats after brain death is more than likely due to being assisted by medicine: respiratory support. If you take this away the patients brain causes breathing to cease and the heart to stop beating. This is called clinical death. Both Brain Death & Clinical Death are the same except for the fact that doctors usually put such patients on life support until family has made the decision to remove said support. There are also times that brain death has occurred but physicians will keep patients on life support if they are organ donors and they must have their organs harvested. After this the physicians will remove said life support and the patient will be pronounced dead.

Nasal septum

I think it's the middle part of the central tendon of the diaphragm

yes they do!

It depends blood doesnt go into the lungs but if your talking about how does blood travel threw lungs its by veins.

this is an assinine question. your HR is not static... unless you have a pacemaker that is set at 75... your a bright kid... do the math.... but i can tell you that your HR was only 75 bpm for that 1 minute that you tracked it, as soon you got up and walked away it changed.

the right side is bigger because it has to pump blood to the whole body
