Of all the organs in the human body, the heart is without a doubt the hardest worker. Beating an average of 72 times per minute, it's responsible for pumping 2,000 gallons or more of blood through the body each day.
Your heart pumps a lot of blood
Your heart is an incredibly hardworking organ. In five minutes, it will pump five litres of blood around your body.
Heart is the organ of the human body which is continuously pumping the blood throughout the body.
The heart is one of the most complex and arguably the most vital organ contained within the human body.
Your heart is sort of like a pump, or two pumps in one. The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body.
At an average of 80 beats per minute, most of us will manage less than four billion beats in our lives. But you don't die because you run out of heartbeats – you run out of heartbeats because you die.
When the heart stops, the lack of oxygen-rich blood can cause death or permanent brain damage within minutes. Time is critical when you're helping an unconscious person who isn't breathing. If you see someone who's unconscious and not breathing normally, do the following: Call 911 or emergency medical help.
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.
Of course the brain stem which sits at the bottom of the brain and connects to the spine was normal. Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it.
Each cell got all essential nutrients through blood which is pumped by heart. So, without it, no one can live. In serious heart failure patients, a total artificial heart saves the life, but a transplant is necessary. So without heart, survival is not possible.
1-3am is the time of the Liver and a time when the body should be alseep. During this time, toxins are released from the body and fresh new blood is made.
The hours between 1am and 3am are governed by the liver meridian. Emotionally it is associated with anger and physically associated with your shoulder. The hours between 3am and 5am are governed by the lung meridian.
Organ and peak functionality
3–5 a.m. Lung: This period is when the lungs are at their peak energy. It's is believed to be an ideal time to exercise, as opposed to later in the day. 5–7 a.m.
Kidneys: Kidneys are the most needed and most commonly transplanted organ.
The Stapedius, the smallest skeletal muscle in the human body, which is about 1 mm in length, is regarded to be the weakest muscle.
Because the brain is so rich in nerve cells, or neurons, it is the most energy-demanding organ, using one-half of all the sugar energy in the body. Brain functions such as thinking, memory, and learning are closely linked to glucose levels and how efficiently the brain uses this fuel source.
An unexpected discovery made by an international team, examining the results of an EEG on an elderly patient, who died suddenly of a heart attack while the test was in progress.
“You can live without bone covering your brain, but it's dangerous,” Redett says. “If you look at photos of him preoperatively, you can see that he was pretty sunken in and had a sizeable indentation from the top of his head down.”
In brain dead cases, the spirit or soul is usually out of the body, though often the brain dead person's spirit stays with the body until life support is switched off.
Heart is the only organ in the body which never rest throughout the entire life. The heart is a hollow muscle that pumps blood throughout the blood vessels by repeated, rhythmic contractions.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born. When you look at a baby's face, so see mostly iris and little white. As the baby grows, you get to see more and more of the eyeball.
Some people have chest pain before they become unconscious from cardiac arrest. However, you won't feel pain once you lose consciousness.
When you sneeze, the intrathoracic pressure in your body momentarily increases. This will decrease the blood flow back to the heart. The heart compensates for this by changing its regular heart beat momentarily to adjust. However, the electrical activity of the heart does not stop during the sneeze.
Newswise — People may feel a flip-flop in their chest when they're under stress, haven't slept well or even during normal activity. They may say, “I felt my heart stop for a second.” But in most cases, that heart-stopping feeling is actually an extra heartbeat, called a premature ventricular contraction (PVC).
