In this video, we reveal 15 amazing facts about the human body. Our bodies are made up of many biological systems. They carry out specific functions necessary for everyday living. You’ll quickly realize how amazing your body really is if you think about everything it does to keep you functioning. At any given time, your body’s doing numerous things that you’re not even aware of. It digests your dinner and it is growing new skin. It carries vital oxygen to your cells from your head to your toe.
There are many amazing facts about the human body. In addition to the basic functions, we learned in school! But first, let’s go over the body systems to refresh your memory.
To begin, we have a circulatory system. It moves blood, nutrients, oxygen, carbon dioxide, and hormones, around the body. Followed by the digestive system. Its job is to break down and absorb food, and remove waste. Next, we got the endocrine system. Its function is secreting hormones into the blood. These hormones then travel to different tissues regulating various bodily functions. Such as metabolism, growth and sexual function. The immune system is the body’s defense. It protects us against bacteria, viruses and other pathogens that may be harmful. Then we have the lymphatic system that plays a role in the body’s defenses. Our nervous system controls both voluntary action and involuntary actions. It sends signals to different parts of the body. Your body’s muscular system aids in movement, blood flow, and other bodily functions. We also have the reproductive system that allows us to reproduce.
Of course, the skeletal system supports all that! Our skeleton helps us move. But, it’s also involved in the production of blood cells and the storage of calcium. The respiratory system allows us to take in vital oxygen and expel carbon dioxide via breathing. While the urinary system helps eliminate a waste product called urea from the body. Urea is produced when certain foods are broken down. Last, but not least, our skin, the integumentary system protects us from the outside world. It is our first defense against bacteria, viruses and other pathogens.
Our bodies are truly magnificent machines! They carry many mysteries, and some you probably don’t even know about. Did you know that there are about 10 times more bacterial cells in your body than human cells? Have you ever wondered how many strands of hair you have on your scalp?
