The human body is an incredibly complex and intricate system, one that still baffles doctors and researchers on a regular basis despite thousands of years of medical knowledge. There are many complicated mind-boggling processes that are carried out every second by our bodies. It is really important to have knowledge about the human biology basics in order to make informed decisions that will be helpful in keeping your body working. You will be astonished and amazed by knowing the interesting facts about the human biology.

 

These are some of the human biology basics everyone should be aware of:

  1. We have more non-human cells as compared to human cells:

According to a microbiologist of U.I., Carolyn Bohach, there are around 10 times more bacteria cells living inside your body as compared to human cells. These bacteria don’t harm us rather they are helpful in performing key bodily functions like digestion.

  1. The shape of eyeballs have an impact on the eyesight problems:

Both farsightedness (hyperopia) and nearsightedness (myopia) can be (and most often are) caused by alterations in the growth or length of the eye. However, a change in the shape of the lens will also affect the uncorrected focal distance – that is, nearsightedness or farsightedness. Myopia can be the result of a cornea – the eye’s outermost layer – that is too curved for the length of the eyeball or a lens that is too thick. Farsightedness (hyperopia) is the opposite of myopia and is usually caused by shortening of the eyeball.

 

  1. Our brain does double duty when we are asleep:

When we are sleeping, our brain is extraordinarily active. As it turns out, most of that activity helps the brain to learn and remember. Sleeping is involved in the learning and memory process in several important ways such as: recovering forgotten skills, selectively preserving emotional memories and helping us to remember the sequence of events.

 

  1. We have more than five senses:

When we think of human senses we think of eyesight, hearing, taste, touch and smell. Yet we have always known that we are capable of sensing much more than this. The commonly held human senses are as follows:

  • Taste
  • Sight
  • Pressure
  • Touch
  •  Sound
  •  Itch
  •  Hunger
  • Proprioception (This sense gives you the ability to tell where your body parts are, relative to other body parts.)
  • Pain
