Quick fact. Ready? Our heart is able to pump completely on its own through ways of self depolarization. Not only this, but it's auto-rhythmic, in which it regulates its own pace.

Quick fact. Ready? Our arteries are made up of three main layers. The innermost layer contains endothelial cells, The middle layer is smooth muscle, While the outermost layer is mainly elastic connective tissue. And even that is a simplified version of it. Isn't the human body so complex?

Quick fact. Ready? One of the main ligaments on the bottoms of our feet is known as the 'spring ligament.' This is right around where our feet arch the highest. It's very important when it comes to walking, for it helps to absorb the impact that it has on the body.

Quick fact. Ready? There is a negative pressure that is kept outside of our lungs and in our thoracic cage. Why is this so? To prevent our lungs from completely collapsing in on themselves! Thank goodness.

Quick fact. Ready? When we stand on our tippy toes or wear high heels, we are reducing the area of contact between our tibia (a shin bone) and talus (a foot bone). In this state, one is more vulnerable to injury due to the lower amount of stability between the two.

Quick fact. Ready? Nitric Oxide is a compound produced in the body that helps to increase blood flow. How? By causing a relaxation response in blood vessels, allowing for more to pass through. However, Nitric Oxide really only exists in the body for about five seconds before it breaks down into Nitrogen and Oxygen. Weird.

Quick fact. Ready? A woman's egg is one of the largest cells of the human body, which can actually be seen by the naked eye. And one of the smallest cells of the human body? A man's sperm. Strange how the body works, isn't it?

Quick fact. Ready? Many of our joints are lined with a special substance called hyaline cartilage. This is meant to greatly reduce the friction between our bones as they slide across one another during movement.

Quick fact. Ready? Humans only have four teeth that are supposedly built for chewing meat. The rest of them are structured to better suit plant eating.

Quick fact. Ready? The length of the human GI tract is much similar to those of herbivores, while carnivorous animals tend to have a much shorter colon.

Quick fact. Ready? Probiotics can be of many origins; including human, dairy, plant, or soil. Human strains may stay the longest in the GI tract for about a week or so before being excreted. Why? Because it is only the probiotics that we are exposed to during the first year of our lives that are able to stay in our guts forever.

Your heart; the one that is beating right at this very moment, As you read this sentence, As it sends blood to your magnificent brain, Fuelling your thoughts as you wonder what point I'm trying to make, Beats for you constantly. You, and only you. It's self regulating itself constantly to ensure that your body gets enough blood and oxygen at every single moment. You have always had a secret admirer, and today is the day you realize who that is; None other than your own brilliant heart.

Quick fact. Ready? Immediately following a mild or major concussion, there is a decreased amount of blood flow to the brain. This is very dangerous, for the brain actually demands more blood flow to heal itself properly. Thus, one must be very careful during this period, for one is at a much greater risk of a secondary concussion.
