The skin is the largest organ. The skin is a very flexible organ. The human skin has many layers. Your skin gives you the ability to feel things. The human body has many features and the skin is just one of the many. The skin is one of the most important organs in our bodies. There are three layers of skin, the epidermis, the dermis, and the hypodermis. The skin protects from the suns harmful rays. It keeps us hydrated by preventing fluid loss. The skin also produces vitamin D to maintain strong bones. Healthy hint= Do not stay in the sun to long without suntan lotion. The skeleton system is very important to the human body. When you’re a baby you have over 300 hundred bones in your body. The spine forms from curves. Calcium helps build up your bones and can prevent you from breaking your bones. Your bones protect your organs. The bones are very important to the human body. The skeleton has three major jobs, to protect the vital organs, gives us our shape, also allows to move and walk. When you are born you have around 350 bones in your body. When you are a adult you will only have 206 bones in your body. When you get older some bones will join together. Our bones are held together by strong stretchy bands called ligaments. www.google.com.webloc Bones are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone mass faster than it removes old bone. After about age 20, you can lose bone faster than you make bone. A major disease affecting your bones is Osteoporosis. Osteoporosis, literally means ‘porous bones’, and is a disease that causes the bones in our body to become fragile and prone to break. Osteoporosis is a major public health threat for an estimated 44 million Americans, or 55 percent of the people 50 years of age and older. To have strong bones when you are young, and to prevent bone loss when you are older, follow these guides: eating a well-balanced diet rich in calcium and vitamin D; participating in regular exercise; taking safety precautions to protect your bones and prevent falls; avoiding excessive dieting and excessive thinness http://www.nof.org/osteoporosis/diseasefacts.htm http://www.health.state.ny.us/diseases/conditions/osteoporosis/promote.htm Nervous tissue is made of two main cells: neurons and glial cells. Neurons send nerve messages. When you are born you have over the number of nervous cells than all the stars in the sky. Nervous cells send shock waves through your body when you are getting injured, so the nervous cells can protect you being seriously hurt. As you can see the nervous system is very important to the human body. The nervous system of an organism is a network of cells made to process information and cause reactions in the body parts . www.emc.maricopa.edu/.webloc http://ann13tn.tripod.com/id4.html In the human body the nervous system has two main parts, the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and spinal chord. The peripheral nervous system consists of all the neurons in the body. Healthy hint= Eat foods with calcium in them. www.clarian.org/.../graphics/images/en/8679.jpg The muscles in the human body are very important to use. You need your muscles to be able to stretch and bend your body. Your muscles can get stressed and strained. Your muscles can grow if you exercise. One of your muscles are the bicep, the bicep is the muscle that is near the Humurous (bone). There are many muscles in the human body and they are all very important. The human muscles are in mostly every part of the body. There are more than 650 individual muscles in the human body. Muscle cells contain contractile filaments that move past each other and change the size of the cell. They are classified as skeletal, cardiac, or smooth muscles. Their function is to produce force and cause motion. http://en.wikipedia.org/wiki/Muscle Healthy hint= exercise daily. http://www.musclesmagic.com/wp-content/uploads/2009/07/400pxMuscles_anterior_labeled.png The Digestive System is very important to the human body . The digestive system is a series of organs and glands that process food. In order to use the food we eat, our body has to break the food down into smaller molecules that it can process. It also has to excrete waste. In all there are about 30 feet of these convoluted pipe works, starting with the mouth and ending with the anus. The digestive system is made out of several hollow organs, mouth, esophagus, stomach, small intestine, large intestine, and anus. On the way the food is broken down, sorted, and reprocessed before being circulated around the body to nourish and replace cells and supply energy to our muscles. For a person to stay healthy, proper functioning of the digestive systems is necessary. Healthy hint= Eat right and not fast. http://www.setbc.org/curriculumset/resources/digestive_system/digestive_system.gif The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat, our body has to break the food down into smaller molecules that it can process; it also has to excrete waste. Most Digestive organs are tube-like shaped and contains food as it makes it way through the body. The Digestive System is a long, twisting tube that runs from the mouth to the anus plus a few other organs that produce or store digestive chemicals. The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical. After being chewed and swallowed, the food enters the esophagus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we're upside-down. action of salivary enzymes. http://www.enchantedlearning.com/subjects/anatomy/digestive/ The respiratory system is very important to the human body. The Respiratory System has many organs that work together to move oxygen through the body to help us breathe. When air passes through the nose to the nasal passages called the windpipe, it gets filtered, moistened, and heated. The lungs are the main part of the respiratory, which enables the exchange of oxygen and carbon dioxide in the blood. With out the Respiratory System we would not be able to breathe. http://www.buzzle.com/articles/respiratory-system-facts.html The Respiratory System has many functions that are vital to the human body. Every minute we breathe, we take in 13pints of air. We breathe about 9 to 20 times every minute. We inhale and exhale about 22,000 times per day and in the process, transport about 300 cubic feet of air. Asthma is a long – standing (chronic) disease. When you have asthma, your airways are over sensitive and inflamed. The tubes that carry air into the lungs are called airways or bronchioles. They are more sensitive in people with asthma. They react to asthma triggers such as colds, cigarette smoke and exercise faster and more strongly than normal airways. More than 2,000,000 people have learned to manage their asthma at home. Healthy hint= when you have asthma always carry an inhaler. http://www.texaschildrenspediatrics.org/healthlibrary/images/respirat.gif The Heart is one of the most important organs in the human body. Your heart is located in the center of your chest between your lungs. An adults heart is the size of a fist. It is important to eat healthy meals and exercise regularly. If you keep your body in good health it makes the heart a more efficient organ. The human heart beats about 50 to 100 times each minute for a total of 100,000 times a day. An adult heart pumps about 5 quarts of blood each minute. That is almost 2,000 gallons of blood each day. A man’s heart weighs about 10 ounces. Without the heart no one would be able to survive. Heart disease is a common cause of death for many people. More than 24 million people have heart disease and more than 900,000 people die from heart disease each year. Fortunately there are many ways to prevent heart disease and live longer: No Smoking or tobacco Regular exercise at least 30 minutes per day Eat a heart-healthy Maintain a healthy weight http://www.mayoclinic.com/health/heart-disease-prevention/WO00041 http://www.alabelleddiagramofthehumanheart.net/images/revi ews/diagram-3.jpg The Circulatory System is very important to the human body. The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to all of your body cells. The Circulatory has three major parts, the Heart, the Blood, and the Blood Vessels. Without the Circulatory System we would not be able to live. The circulatory system is very interesting to learn about. It passes nutrients, gases, hormones, blood cells, etc. to and from cells to fight diseases and help keep body temperature stabile. The main parts of the circulatory system are the heart, the blood, and the blood vessels. Also, the digestive system works with the circulatory system to provide the nutrients the system needs to keep the heart pumping. Healthy hint= Do not eat a lot because it makes the blood travel slower through your body. http://www.ashlandschools.org/morgan_cottle/body/circ.gif Circulatory System- The bodily system consisting of the heart, blood vessels, and blood that circulates blood throughout the body, delivers nutrients and other essential materials to cells, and removes waste products. Glial cell- Any of the cells making up the glia, such as the star – shaped cells called astrocytes Neurons cell- A cell of the nervous. Neurons carry and transmit electrical signals throughout the nervous system. Esophagus- The muscular tube that connects the mouth to the stomach and serves as a passageway for food. Hypodermis- A subcutaneous layer of loose connective tissue containing a varying number of fat cells.
