25 Amazing Facts About Human Body

Even though you're around human bodies all day (after all, you have one of your very own), you probably don't know everything there is to know about them. Each of our bodies are a miracle; it's amazing they work the way they do, day in and day out. If you thought what our bodies could do before, once you read this list of insane facts about the human body, you'll be in awe. Never take your own body for granted, because some of the things it can do are mind-blowing.

1.) The average person produces enough saliva in their lifetime to fill 2 swimming pools.

2.) Every 60 seconds, your red blood cells do a complete circuit of your body.

3.) Sometimes, when you have to pee, you can visibly see that your bladder is bigger.

4.) Most babies are born with blue eyes; exposure to UV light brings out their true color.

5.) Most westerners consume 50 tons of food and 50,000 liters of liquid in their lifetime.

6.) It can take your finger and toenails 1/2 a year to grow an entirely new nail (from base to tip).

7.) The muscles that control your eyes contract about 100,000 times a day (that's the equivalent of giving your legs a workout by walking 50 miles).

8.) Over the course of your lifetime, you'll shed about 40lbs of skin.

9.) Your brain uses about 20% of your oxygen and caloric intake.

10.) In each kidney, there are 1 million filters that clean around 1.3 liters of blood every minute and push out close to 1.5 liters of urine every day.

Relationship Between Physics and Biology

Biology is the study of living organisms. Physics is the study of matter and the laws of nature to understand the behavior of matter and the universe. The Biophysical Society explains that, when scientists combine physics and biology, they learn more about biological systems on a molecular or atomic level. By taking a quantitative approach to biological questions, a scientist gains a better understanding of patterns that occur in living organisms.

This Is The Main Relationship Between Physics and Biology.

Definition of Biology

Biology is the study of life and organisms. This natural science includes the origin, evolution, function, structure and distribution of living organisms. The discipline also concerns itself with topics like the classification of organisms, an organism’s ability to regulate its internal environment, how structures function as a whole, and the interaction of living organisms within an environment. Basic biological concepts include the study of cells as basic structural units of life, genetics and heredity, and transformation of energy by organisms while growing, developing and adapting to their environments.

Definition of Physics

Physics is the study of energy and matter and how the two interact through time and space. As physicists study the natural word, they attempt to answer questions about the behavior of the universe. Physicists study events that occur in nature, such as the passing of time, and use principles or patterns to explain and make predictions about such events in the natural world.

Biology and Physics Working Together

Physics provides the basis for biology. Without space, matter, energy and time -- components that make up the universe -- living organisms would not exist. Physicist Richard Feynman said that everything on earth is made of atoms, basic units of matter, that constantly move. Since biology has its foundation in physics, it applies physical natural laws to the study of living organisms, according to Muskegon Community College. For instance, physics helps explain how bats use sound waves to navigate in the dark and how wings give insects the ability to move through the air. The American Physical Society shares that many flowers arrange their seeds or petals in a Fibonacci-like sequence to maximize exposure to light and nutrients. In some cases, biology helps prove physical laws and theories. Feynman states that biology helped scientists come up with the law of conservation of energy.

The Odd Couple

There are instances when physics disproves or can’t explain biological occurrences and vice versa. For example, physics can’t account for the encryption of traits in DNA or historical contingencies as they relate to evolution. Physics and biology can’t explain the origin of life or how inorganic objects transitioned to organic life. Cornell University states that the biological theory of evolution contradicts the second law of thermodynamics because nature can’t create order out of disorder -- and evolution is a process that creates increasing levels of order. Scientists wishing to bridge the gaps between physics and biology use biophysics, a science that relies on theories and methods related to physics to study and explain biological systems.

12 Surprising Facts About Sex And Women

1. Cycles of light affect our fertility
Women used to menstruate during the new moon (when it’s dark at night) and ovulate during a full moon (when it’s light). Now, in a world full of artificial lighting and bright screens, women are not as in tune with the connection between their biology and nature. Some have tried “lunaception,” altering the lights in their bedrooms based on the moon lighting to change their ovulation.

2. Women can get pregnant five to eight days after having sex
Studies have shown that some sperm can live in the cervical mucus crypt before the egg is actually fertilized for anywhere from five to eight days after sex.

3. Wearing high heels can negatively affect a woman’s orgasm
Certain high-end shoe brands developed the arch in their high-heeled shoes to approximate the arch in a woman’s pelvis when she is having an orgasm. The heels create a contraction in the pelvic floor, which is problematic because the pelvic floor then cannot contract further during orgasm. “An orgasm is usually like going from zero to 60,” explains Fromberg. “If you’re already at 55 [from wearing heels], you’re not going to have a full experience.”

4. Orgasms can make women more creative
Studies have shown that orgasms can make women more confident, productive and creative. And it’s a feedback loop—women achieve fuller orgasms when they are being creative.

5. Birth control pills dampen the libido
Any hormonal contraception has that psychological side effect. Sometimes women even have trouble conceiving once they’re off the pill because while they may have been attracted to their partner on the pill, they’re not actually compatible with each other biochemically without the extra hormones.

6.  Sitting in chairs can arouse women
Pudendal nerves, underneath the buttox and the sitting bones, feed arousal tissues (in the vagina, clitoris, anus, etc.). Sitting in a certain kind of chair pressing on the pudendal nerves in a certain way can lead to sexual arousal.

7. …But it can also dampen their orgasms
On the other hand, sitting in chairs for most of the day shortens the pelvic floor and psoas muscles—muscles which are essential to a full-body orgasm. When these muscles are tight from sitting too much, women find it harder to achieve a great orgasm.

8. Women have three erogenous zones 
The clitoris, the G Spot, AND the opening of the cervix. Some argue nipples belong on that list too.

9. Nerve endings are distributed differently in every woman’s vagina
Like a snowflake, each woman is unique in that her nerve endings are distributed in her genitalia differently than anyone else. That means, every woman needs to employ slightly different methods to achieve orgasm.

10. The pulsations a woman feels during orgasm are actually her uterus trying to gather sperm
Round ligaments that end in the labia majora “rock the uterus back and forth during orgasm so that the cervix has the opportunity to potentially scoop semen up that may have pooled in the back of the vagina to enhance fertility,” says Fromberg.

11. Being well hydrated leads to better orgasms
Because the body is mostly fluid, being hydrated enhances people’s ability to achieve orgasm.

12. All woman can achieve orgasm
Almost no woman was born unable to achieve an orgasm. “Women have the innate machinery programmed to have orgasms,” Fromberg explains. “But not everybody learns how to use that machinery well.”
