How many organs do we have in our body?
In the study of anatomy, the term viscus refers to an internal organ. Viscera is the plural form. The number of organs in any organism depends on which precise definition of the term one uses. By one widely used definition, 79 organs have been identified in the human body.
What are the major organs of the human body?
Humans have five vital organs that are essential for survival. These are the brain, heart, kidneys, liver and lungs. The human brain is the body’s control center, receiving and sending signals to other organs through the nervous system and through secreted hormones.
What is the smallest organ in human body?
pineal gland
What is the biggest human organ?
Skin is our largest organ—adults carry some 8 pounds (3.6 kilograms) and 22 square feet (2 square meters) of it.
What is the strongest organ in the human body?
The heart has the ability to beat over 3 billion times in a person’s life. The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What’s the heaviest organ in your body?
skin
What organ has the most blood?
The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. The liver consumes about 20% of total body oxygen when at rest, so the total liver blood flow is quite high. Blood flow to the liver is unique in that it receives both oxygenated and partially deoxygenated blood.
What is the brightest thing in the universe?
The Brightest Quasar of the Early Universe Shines with the Light of 600 Trillion Suns. Scientists have discovered the energetic core of a distant galaxy that shatters the record for the brightest object in the early universe, blazing with the light equivalent to 600 trillion suns.
Do quasars last forever?
Thus the quasar lifetime can shed light on the growth and evolution of SMBHs. Current estimates of the quasar lifetime are not very tight — they span a couple of orders of magnitudes from 106 to 108 years.
What is the most powerful explosion in the universe?
GRB 080916C is a gamma-ray burst (GRB) that was recorded on September 16, 2008 in the Carina constellation and detected by NASA’s Fermi Gamma-ray Space Telescope. It is the most powerful gamma-ray burst ever recorded.
Will our Sun become a black hole?
No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
What is the strongest energy on Earth?
gamma-rays
What would happen if a gamma-ray burst hit a black hole?
As a massive star collapses into a black hole, it sends out a brilliant SOS signal in the form of ultrabright gamma-ray bursts. Now, scientists have found something very peculiar about those mysterious signals: They seem to reverse time.
How fast is a gamma ray burst?
Gamma ray bursts are short-lived blasts of gamma ray radiation, the most energetic of all forms of electromagnetic radiation. Lasting between a few thousands of a second to several minutes, these events can release a million trillion times as much energy as our Sun.
What can escape a black hole?
How can we learn about black holes if they trap light, and can’t actually be seen? No light of any kind, including X-rays, can escape from inside the event horizon of a black hole, the region beyond which there is no return.
What would happen if a neutron star was placed close to the earth?
Neutron stars can be dangerous because of their strong fields. If a neutron star entered our solar system, it could cause chaos, throwing off the orbits of the planets and, if it got close enough, even raising tides that would rip the planet apart. But the closest known neutron star is about 500 light-years away.
Could you walk on a neutron star?
No. A neutron star has such an intense gravitational field and high temperature that you could not survive a close encounter of any kind. The intense gravity would then flatten what was left of you as you merged into the super-dense crust of the neutron star. …
What would happen if a star hit Earth?
According to a 2016 study, supernovae occurring as close as 50 light-years from Earth could pose an imminent danger to Earth’s biosphere—humans included. The event would likely shower us in so much high-energy cosmic radiation that it could spark a planetary mass extinction.
Are neutron stars hot?
Neutron stars produce no new heat. However, they are incredibly hot when they form and cool slowly. The neutron stars we can observe average about 1.8 million degrees Fahrenheit, compared to about 9,900 degrees Fahrenheit for the Sun.
What is a black neutron star?
The object — dubbed a “black neutron star” by the BBC — was first detected in August, when it merged with a massive black hole of 23 solar masses, transforming into a final black hole of 25 solar masses some 800 million light-years from Earth.
Will a neutron star hit Earth?
If an object were to fall from a height of one meter on a neutron star 12 kilometers in radius, it would reach the ground at around 1400 kilometers per second. However, even before impact, the tidal force would cause spaghettification, breaking any sort of an ordinary object into a stream of material.
Is a neutron star hotter than the sun?
A: A neutron star is born very hot (leftover heat from when the star was still “normal” and undergoing nuclear reactions) and gradually cools over time. For a 1 thousand to 1 million year old neutron star, the surface temperature is about 1 million Kelvin (whereas the Sun is 5800 K).
Which is hotter the sun or lava?
But even lava can’t hold a candle to the sun! At its surface (called the “photosphere”), the sun’s temperature is a whopping 10,000° F! That’s about five times hotter than the hottest lava on Earth. A temperature of 27 million degrees Fahrenheit is more than 12,000 times hotter than the hottest lava on Earth!
What is the 3rd largest organ in the body?
Lungs are the third-largest organs in the human body.

Can you live without a brain?
Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it. But the rest of the brain is obviously capable of some remarkable feats, with one part able to compensate for deficiencies in another.
Can a person live without a spleen?
The spleen is a fist-sized organ in the upper left side of your abdomen, next to your stomach and behind your left ribs. It’s an important part of your immune system, but you can survive without it. This is because the liver can take over many of the spleen’s functions.

How many eggs are females born with?
At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman’s reproductive lifetime. Fertility can drop as a woman ages due to decreasing number and quality of the remaining eggs.

Your menstrual cycle and period are controlled by hormones like estrogen and progesterone. Here’s how it all goes down: You have 2 ovaries, and each one holds a bunch of eggs. The eggs are super tiny — too small to see with the naked eye.
Is period blood clean?
Contrary to that belief, the blood you menstruate is just as “clean” as the venous blood that comes from every other part of the body and it’s harmless as long as you don’t have any bloodborne diseases (pathogens aren’t picky when it comes to manifesting in bodily fluids).
Why do I poop so much on my period?
These chemicals stimulate the smooth muscles in your uterus to help it contract and shed its lining each month. If your body produces more prostaglandins than it needs, they’ll enter your bloodstream and have a similar effect on other smooth muscles in your body, like in your bowels. The result is more poop.
