How Your Body Works: 1 (Children's World)

Product Information

Your blood flows through your heart and your lungs to become re-oxygenated before being pumped to the rest of your body. Oxygen is added to your blood in four main steps, they are: In the brain…The smell of food triggers your brain, which sends a message to your gut to prepare for a meal. The gut then starts producing digestive juices and enzymes to transform the food into usable molecules for the body. How Your Body Works How Your Body Works If you’ve ever wondered how the trillions of cells in your body work together to keep you alive, Live Science has the answers. Throughout this collection, you’ll find out how complex networks of neurons control our thoughts and actions, and how specialised systems perform vital functions such as keeping our blood pumping, making our muscles move, and protecting us from harm.

Wear protective goggles in classes where debris or chemicals could go flying, such as wood shop, metal shop, science lab, or art. We have long thought that the appendix was a remnant of our evolution: an organ that once served a purpose, but now doesn't do anything other than getting acutely infected, requiring emergency surgery. What a useless little bugger.For instance, the yellow marrow inside your bones stores essential fatty acids to use in case you run low. Minerals from your bone matrix can be drawn out to alkalise the blood if it gets too acidic. The bones can even store harmful heavy metals to keep them from damaging your organs and glands. The nervous system, which consists of your brain, the spinal cord, and all the nerves throughout your body, controls movement, balance, the five senses, thought processes, and awareness. And how about the last time you felt sad, scared, or upset? Your eyes got a message from your brain to make you cry, and the lacrimal glands made many, many tears. How Can I Protect My Eyes? Your body is made up of minerals, salts, and electrolytes that create a seawater-like system. This gives the nervous system the power to make your body breathe, walk, circulate blood, digest, and perform every other task it does on a daily basis.

In reality, your body is an entire microcosm. How healthy you are depends on your genetics and your epigenetics: your habits, lifestyle, and external environment. Additionally, each blood group can be either positive or negative, resulting in eight possible blood types. The +/- part of a person’s blood type is determined by the presence (or absence) of a third antigen called the Rh factor. Okay, so this one is a little unsettling. Did you know that there are ten times more bacteria cells in our bodies than our own human cells? Of course, most of these bacteria are, if not perfectly harmless, fairly essential to our health, helping us to perform key bodily functions.

When you drink alcohol, your liver oxidises 95 per cent of it. This means your liver converts alcohol into water and carbon monoxide. Your liver can only oxidise one unit of alcohol an hour. Drinking with an empty or full stomach The cornea (say: KOR-nee-uh), a transparent dome, sits in front of the colored part of the eye. The cornea helps the eye focus as light makes its way through. It is a very important part of the eye, but you can hardly see it because it's made of clear tissue. Like clear glass, the cornea gives your eye a clear window to view the world through. What's the Iris? Each of these senses is associated with its own organ (taste with the tongue, smell with the nose) or sensory receptor (the skin contains separate touch, temperature, and pain receptors). 7. Our appendix does actually still have a purpose Every good design contains a reserve tank, and your body is no different. Whether you’re dealing with an injury, illness, or other medical condition, a reserve tank offers a safety net of life-preserving fuel and nutrients. Through the functional medicine lens, you can identify the causative factors that are leading to your health issues and reverse them. When your body has the right resources and environment to thrive, it can’t help but to heal itself!

There isn’t much academic research in the area of self-care for young people who are living with mental health issues. We are trying to find out more about what works for different people so we can better advise other young people what to try. And would you believe it but this girl is AB+! #winning) 3. Our DNA is stored in 23 pairs of chromosomes within the nucleus of every cell in our body DNA has 23 pairs of chromosomes and exists in the nucleus of every cell in our body. The human body contains approximately 6 quarts (5.6 liters) of blood. Blood acts as your body’s transportation system—in one day, your blood travels nearly 12,000 miles (19,312 kilometers). Pumped along by your heart, blood takes oxygen from the air you breathe and nutrients from the food you eat to all the cells of your body. (Your heart pumps 1 million barrels of blood during your lifetime—enough to fill three supertankers.) Blood also keeps cells clean and healthy by transporting waste products away after the nutrients and oxygen have been used for processes such as growth and repair. In addition, blood transports hormones—chemicals made in glands that control a variety of processes—throughout your body. To help your body function like a well-oiled machine, be sure to eat a varied, whole-foods diet. Include foods like: Many people assume that sleep helps the brain rest, but our brains are actually busier while we're sleeping! When we sleep and dream, our brains carry out important functions they cannot while focusing on movement and conscious thought. They also process things we learned and emotions we felt during our waking hours, filing them away in our memories. That’s why sleep is so important to learning.

What does my brain do, besides think?

Take the brain for instance. At its simplest, the brain is a bundle of fat and protein. Fat myelinates your nerve cells and helps speed up communication. Proteins called peptides make up other parts of the brain and neurotransmitters. Glucose (sugar), ketones, and other polysaccharides fuel the brain with energy so we can carry out all our daily functions and think.
