The last one for this mini series is going to be about the brain. Now it is clearly far too complex to cover everything in a minute but here’s just 6 facts!
- A definition of the brain is “An organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating centre of sensation and intellectual and nervous activity”.
- The brain has two sections called hemispheres. The left side of the brain is dominant in languages and the right side is in charge of spatial abilities, face recognition and processing music.
- The corpus callosum is a thick band of nerve fibres that divides the left and right hemispheres of the brain.
- The average brain weighs three pounds.
- Diseases of the brain include Alzheimer’s disease, Parkinson’s disease and multiple sclerosis. Diseases such as these can limit the normal function of the human brain.
- There is no difference between male brains and female brains, although each brain is slightly different to the different balance of hormones in each person.
The definition of the brain came from the oxford dictionary. The second fact comes from live science. The third fact is from the biology about page. Number four comes from the alzheimers association. The fifth fact comes from this fact sheet.The sixth fact came from an article from the New Scientist about research completed at the University of Bern, Switzerland.
Hello! I’m back after being gone for far too long, so this months theme of 6 in 60s will all be about human organs! Starting off with the heart, lets do this!
Heart and Brain: Credit to The Awkward Yeti
- Each day, your heart beats about 100,000 times. It pumps about 23,000 litres (5,000 gallons) of blood around your body.
- The heart has four compartments two smaller upper chambers called the atria and two lower larger chambers called the ventricles. The two sides of the heart are separated by the septum.
- The basics on how blood travels around your heart: The right side of the heart receives dark, de-oxygenated blood which has circulated around your body.It pumps this to your lungs, where it picks up a fresh supply of oxygen and becomes bright red again.The blood then returns to the left side of the heart, ready to be pumped back out to the rest of your body.
- Each of the chambers of the heart are separated by valves, this ensures that the blood only flows in one direction.
- A good belly laugh can send 20% more blood flowing through your entire body. One study found that when people watched a funny movie, their blood flow increased.
- A heart attack is a serious medical emergency in which the supply of blood to the heart is suddenly blocked, usually by a blood clot. Lack of blood to the heart can seriously damage the heart muscle.
