The Wonders Of The Human Body
The Wonders of the Human Body
Created By Stephone Robinson
The human body is one of the most complicated systems in the world doctors still don’t have all of the answers to what makes us tick and maybe will never know but we are breaking into it one piece at a time. Did you know The largest cell in the human body is the female egg or the smallest is the male sperm and technically You use 200 muscles to take one step there are all kind of mysteries to the human body. The average woman is 5 inches shorter than the average. They say pair of human feet contains 250,000 sweat glands or a full bladder is roughly the size of a soft ball. These are just some interesting facts I thought you should know but the coolest two is that The acid in your stomach is strong enough to dissolve razor blade and The human brain cell can hold 5 times as much information as the Encyclopedia Britannica.
Great Ways to stay healthy
If we want to stay healthy, we should protect our liver well. Liver is the major organ responsible for purifying our bodies. Besides, the intestines and kidneys are also important for eliminating toxins from our bodies. Without these organs, we could not survive. to keep your body healthy and have a very good system of internal organs, you can do something starting at home. These techniques are not difficult to learn, but they are very useful. Also healthy eating is a very good way to keep up good health and daily exercising to keep in shape
The Digestive System
The human digestive system is a complex process that consists of breaking down large organic masses into smaller particles that the body can use as fuel. The breakdown of the nutrients requires the coordination of several enzymes secreted from specialized cells within the mouth, stomach, intestines, and liver. The major organs or structures that coordinate digestion within the human body include the mouth, esophagus, stomach, small and large intestine, and liver.Food provides us with fuel to stay a live. From food we get the energy to work and play and the raw materials to build new cells. The food we eat needs to be broken down so that our bodies can use it to make energy. Food is broken down by our digestive system and then taken around our body by the circulatory system (the blood).
The human respiratory system is composed of the nasal passage, the pharynx, larynx, the trachea, bronchi and lungs. It is responsible for the process of respiration that is vital to the survival of living beings. Respiration is the process of obtaining and using oxygen, while eliminating carbon dioxide. It is the process by which human beings take in the oxygen from their environment and give out the carbon dioxide that is produced as a result of chemical reactions within the cells. The specialized system that brings about this critical process of respiration in human beings is known as the human respiratory system. The respiratory system in human beings can be divided into the upper respiratory tract that consists of the nasal passages, pharynx and the larynx and the lower respiratory tract that is composed of the trachea, the primary bronchi and the lungs.
The Circulatory Systems main organ is the heart and the purpose of our heart is so that we can stay alive. The other parts that helps make up this organ are arteries, veins, chambers, valves and vessels. There are 4 chambers: The Right & Left Atrium and The Right & Left Ventricle. The right side of your heart receives oxygen poor blood from the body to the lungs to get rid of carbon dioxide. The left side is oxygen rich which receives blood from the lungs to send back into the body. There are 4 valves: Pulmonary valve, Aortic valve, Tricuspid valve, and Mitral valve. The beating of your heart is the sound of these valves opening and closing. When you take your blood pressure it is the measurement of the force of blood as it goes through your arteries. This system also works with the Respiratory System. A disease of the heart could be a heart attack.
The Nervous System has many different parts. But it’s divided into two main parts: central nervous system (CNS) and the peripheral nervous system (PNS). The spinal cord and brain make up the central nervous system. Its main priority is to get information from the body and sends out instructions. The peripheral nervous system is made up of all the nerves. It sends messages from the brain to the rest of the body. The brain keeps the body in order. It helps to control all of the body systems and organs. The brain communicates with the rest of the body through the spinal cord and the nerves. The spinal cord runs down a tunnel of holes in the backbone or spine. The spinal cord is thick bundles of nerves that connect the brain to the rest of the body. Our fives senses (touch, smell, taste, see, hear) is apart of the central nervous system. Diseases involved with the nervous system are: Alzheimer disease, multiple sclerosis
The muscular system makes up nearly half the weight of the human body, this is why when we train we sometimes put on weight instead of losing it. We put on muscle weight.
The muscles provide the forces that enable the body to move. Muscles stretch across joints to link one bone with another and work in groups to respond to nerve impulses
There are nearly 650 skeletal muscles in the human body!
muscles are attached to the skeleton
They work in pairs: one muscle moves the bone in one direction and the other moves it back again
muscles are voluntary muscles - in other words we think about what movements we want to make and send messages to our nervous system to tell the appropriate muscles to contract.
The skeletal System is all of the bones in the body and this tissue (like tendons, ligaments and cartilage that connects them together) which helps support, protect and move us. It's what keeps out skin, organs and muscles from just falling and making us look like spaghetti. Also, the skeletal system is what keeps a lot of our organs safe. The heart and brain is surrounded by bones to keep protected. Your spine gives your structure. When we are born we have over 300 bones, but as we grow our bones grow and fuse together which give us 206 bones when we finish growing. A few diseases and disorders are Leukemia, Bursitis, Osteoporosis, Sprains and Fractures.
