Heaviest organs in the body


1. Skin: 4,535g 
function: Protects against pathogens; provides insulation; synthesizes vitamin D; regulates temperature; provides sensation

 2. Liver: 1,560g 
function: Breaks down toxins; produces hormones, proteins and digestive biochemicals; regulates glycogen storage

 3. Brain: 1,500g 
function: Drives executive functions such as reasoning; coordinates responses to changes in environment

 4. Lungs: 1,300g 
function: supplies oxygen to be distributed around the body; expels carbon dioxide that is created around the body

 5. Heart: 300g 
function: Pumps oxygenated blood from lungs around the body; pumps deoxygenated blood to the lungs

 6. Kidneys: 260g (pair) 
function: remove waste products; regulate sodium and water retention; filter blood; produce urine and hormones

 7. Spleen: 175g

 8. Pancreas: 70g
 function: Produces insulin and glycogen; secretes enzymes that assist in the absorption of nutrients in the small intestine

 9. Thyroid: 20g

Why do different countries use different mains voltages?

Why do different countries use different mains voltages? the biggest disparity is between the usA on 110V and most of the rest of the world on 230V. America’s lower voltage goes all the way back to thomas edison, who introduced direct current (dC) mains electricity at 110V. edison’s rival nikola tesla showed that long power lines transmitted alternating current (AC) more efficiently than dC. His AC approach won out, but he stuck with edison’s 110V. But by the time electrification spread to europe early in the 20th Century, lamps had filaments that could give out more light and handle greater power loads. so the Berliner elektrizitätswerke company in Germany established 230V as the standard.

Ten most dangerous animals in the world.

10 DANGEROUS ANIMALS 10 Poison dart frog (phyllobates terribilis)  Human deaths/year: Unknown living in the rainforest of colombia, this frog’s skin is coated with enough batrachotoxins to kill at least ten men. 09 Box jellyfish (Chironex fleckeri) human deaths: at least 60 since 1883 each of the sea wasp’s tentacles is armed with about 5000 stinging cells. 08 sloth bear (Melursus ursinus)  Human deaths/year: <2 like other bear species, sloth bears don’t predate humans, but chance encounters can result in deaths. 07 Great white shark (carcharodon carcharias)  Human deaths/year: <30 unprovoked shark attacks on humans are extremely rare – and fatalities even rarer. Great white, tiger and bull sharks are responsible for most. 06 lion (panthera leo) Human deaths/year: ≤100 lion attacks on humans often occur during harvests, but rare outbreaks of mass ‘maneating’ also occur. 05 African elephant (Loxodonta africana)  Human deaths...

Do video games change the brain?

Do video games affect behaviour? Video games are likely able to affect the way we behave in a number of ways. For instance, there’s concern about whether violence in games makes young people more violent. It’s not uncommon for news outlets to blame games every time a crime happens, but how true is that claim? This is controversial even within the scientific community. Yes, exposure to violence seems to affect the brain, but studies have also found that we’re good at distinguishing between real and virtual violence, and aggressive behaviour is better explained by other, mainly socio-economic factors. Numerous studies about the effects of games on the brain had been published, but all that information had not been put together until now. How did you review the research?  We gathered all scientific articles to date and compared results. In total, we found 116 experiments, the first from the 1980s. Many compared regular video game players with people who had never played; other...
