Did You Know? Intriguing Facts That Will Make You Say Wow About Tuitions

Did you know that the human brain is 78% water? That’s one fascinating fact that will make you say wow!

Using “did you know” facts in your writing can help you look like you’re the smartest person in the room. It’s a great way to expand your knowledge base so you can be prepared for any situation!

1. The human brain is 78% water

Your heart is comprised of two hearts, which are separated by a thin muscular wall. The right side of the heart pumps deoxygenated blood to your lungs to collect a fresh supply of oxygen, while the left side of your heart pumps reoxygenated blood back out to the rest of your body.

The human brain is a complex organ with over 7 billion neurons, or cells, connected by trillions of synapses. Water plays a key role in the formation of these neurons, as well as in delivering oxygen to each cell.

2. The human heart is made up of two hearts

The human heart is the muscle at the centre of our circulation system, pumping blood around our body as we breathe. This sends oxygen and nutrients to our cells, organs and tissues, and carries away waste products such as carbon dioxide.

The heart is made up of four chambers: two atria and two ventricles (say: VEN-trih-kulz). Each chamber contracts and relaxes in turn to generate a rhythmic heartbeat.

Our hearts are roughly the size of two clenched fists and sit between our lungs, slightly to the left of our breastbone (sternum). A double-membraned sac called the pericardium surrounds the heart.

The wall of our hearts separates into three layers: the outer epicardium, middle myocardium and inner endocardium. These are surrounded by a double-membraned sac called pericardium, which is lined with fibro-elastic connective tissue.

3. The human body is made up of 80% water

Water is crucial to the functioning of our bodies, and a large percentage of your body is made up of this fluid. It helps to regulate temperature, cushion your brain and spinal cord, transport oxygen and nutrients, and flush out toxins.

Our bodies are composed of two types of water: extracellular water (ECW) and intracellular water (ICW). ECW makes up about one-third of total body water, whereas ICW represents another 2/3.

The water in your blood falls into the ECW category, as does interstitial fluid and transcellular fluid, which are all aqueous mediums that surround cells. Plasma, which is found in your blood, is a mix of water and other dissolved elements that helps control electrolytes, transport oxygen, and clear waste.

The remaining 0.15% of your body is made up of a variety of chemical elements and trace elements. Some of these are essential for life, while others are necessary to keep your body running efficiently but not necessarily needed for survival.

4. The human body is made up of ten bacterial species

The human body is made up of around 20,000 different types of cells. Some of these are made up of proteins, carbohydrates, lipids, nucleic acids and other organic molecules that perform vital functions in the body.

While many people think of bacteria as something to be avoided, some are essential to human survival. They help us digest food, produce protective toxins, and protect against disease.

These microorganisms live in all parts of the body, including our skin, gut and nose, where they contribute to a healthy microbiome. Now researchers have mapped the normal bacterial makeup of healthy adults and are learning more about how a variety of microbes interact with humans.

5. The human body is made up of 20,000 words

The human body is made up of thousands of different tissues, organs and systems. Each of these parts works together in complicated relationships from the micro to macromolecular levels. For example, your blood consists of tiny molecules made up of proteins, carbohydrates and fats that carry oxygen from your lungs to the rest of your body, your intestines are filled with cells that absorb and release nutrients as they are consumed and used, and your brain is a complex web of nerve fibers connecting your eyes, ears, and muscles.

The main building blocks of the body are water (a molecule composed of two hydrogen and one oxygen atom), organic molecules (organic compounds that include proteins, carbohydrates, fats and nucleic acids) and inorganic minerals such as calcium, phosphorus, sodium and magnesium. These molecules make up around 99% of the total mass of your body.
