    Diseases A-Z

    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Blood, Heart and Circulation.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.Blood refers to the fluid that circulates around the arteries, capillaries, veins and heart of human beings which carry with it nourishment and oxygen to and from, removing along the way impurities and waste products from all parts of the body.The heart is an organ that is hollow and muscular present in human beings which contract rhythmically acting as a natural force pump which helps to maintain the flow and movement of blood throughout the body.Circulation refers to the ability of the body to move blood and lymph fluids through blood vessels around the body which are supported by the heart and its pumping action.In addition to filtering by body location Blood, Heart and Circulation, you may also filter by Brain and Nerves, Eyes and Vision, Mouth and Teeth, Bones, Joint and Muscles, Ear, Nose and Throat, Lungs and Breathing and lastly Skin, Hair and Nails.
    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Bones, Joints and Muscles.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.The bones of the human body are made of very hard tissue that helps protect the organs and supports the muscles. This tissue is mainly composed of collagen and calcium phosphate. The combination of these two substances allows the bones to have both flexibility and rigidity.The joints are areas where more than one separate bone is joined together. The body has multiple types of joints. There are mobile joints where the joint is flexible and the bones can move around. There are also joints where bones are joined together but the movement is not a priority. The joints help the body create a range of movement.The muscles of the human body are made of bundles of fibers that contain muscle cells. Movement is created when the muscles contract and relax. The muscles in your stomach help you digest food and the muscles in your arm help you reach things.In addition to filtering by body location Bones, Joints and Muscles you may also filter by Blood, Heart and Circulation, Brain and Nerves, Eyes and Vision, Mouth and Teeth, Ear, Nose and Throat, Lungs and Breathing, and lastly Skin, Hair and Nails.
    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Brain and Nerves.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.The brain is a big mass of nerve tissue that is located inside the skull. There are billions of nerve cells within the brain. They form connections with each other to help facilitate various cognitive processes such as learning, memorizing, and sensory processing.Nerves are bundles of fibers that transmit electrical messages between the central nervous system and the rest of the body. These bundles can be found throughout various areas of the body. The motor nerves and the sensory nerves are the two main types of nerves in the human body. The motor nerves send information from the muscles to the brain. Sensory nerves detect environmental stimuli and send that information to the brain. The brain processes these electrical signals before sending command signals back to the cells that sent them. The nerves work together with the central nervous system to decide how to coordinate muscle movement.In addition to filtering by body location Brain and Nerves you may also filter by Blood, Heart and Circulation, Eyes and Vision, Mouth and Teeth, Bones, Joint and Muscles, Ear, Nose and Throat, Lungs and Breathing and lastly Skin, Hair and Nails.
    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Ears, Nose and Throat.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.The ear is a sensory organ and it helps the human body to detect sound. It also helps the body stay physically balanced. Sound waves enter the ear canal and reach special instruments of the ear to be processed into electrical impulses. Next, the electrical impulses are sent to the brain to be understood as sound.The nose is a sensory organ that helps the human body to detect smells. There are special nerve cells within the nose to sense the smells. The nose is also an area for air to enter and leave the lungs. Any additional debris in the air is routinely filtered out by the mucous membranes within the nose.The throat is a muscled passageway that connects both the nose and mouth to the esophagus and trachea. The throat has a tissue flap called the epiglottis. It acts as a cover to block food and liquids from entering the trachea.In addition to filtering by body location Ears, Nose and Throat you may also filter by Blood, Heart and Circulation, Brain and Nerves,  Eyes and Vision, Mouth and Teeth, Bones, Joint and Muscles, Lungs and Breathing and lastly Skin, Hair and Nails.
    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Eyes and Vision.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.The eyes are a pair of sensory organs that sense visual stimuli. They sit at the front of the skull. When the light reaches the eyes, the special receptor cells within the eyeballs sense the light. Next, the special receptor cells send the information in the form of electrical impulses to the brain. The brain processes those electrical impulses into the visual images perceived as vision.Vision is the ability to perceive the visual images in the environment. Humans have binocular vision. Binocular vision is the combination of two visual images that have different angles from each other. Each eye sits at a different area in the skull. So when the eyes are looking at an object there is a difference in the angle of the object's location. With binocular vision, there is greater accuracy in perceiving depth perception because of the 3D vision that results from the converged images.In addition to filtering by body location Eyes and Vision you may also filter by Blood, Heart and Circulation, Brain and Nerves, Mouth and Teeth, Bones, Joint and Muscles, Ear, Nose and Throat, Lungs and Breathing and lastly Skin, Hair and Nails.
    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Lungs and Breathing.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.The lungs are a pair of pink spongy lobes that sit within the chest area of the human body. The role of the lungs is to take oxygen into the body and expel carbon dioxide out. When breathing in, the air enters the lungs to reach tiny air sacs called alveoli. The alveoli are covered with tiny blood vessels where blood cells are waiting to receive oxygen. At that same area, blood cells are also dropping off carbon dioxide for the lungs to push out of the body.Breathing is the inhalation and exhalation of air. As you take a breath, the diaphragm contracts to allow more room for the lungs to expand. The additional room helps allow the air to enter the lungs more easily. When you breathe out, the diaphragm relaxes and waste gases are pushed out of the lungs and into the air.In addition to filtering by body location Lungs and Breathing you may also filter by Blood, Heart and Circulation, Brain and Nerves, Eyes and Vision, Mouth and Teeth, Bones, Joint and Muscles, Ear, Nose and Throat, and lastly Skin, Hair and Nails.
    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Mouth and Teeth.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.The mouth is a mobile cavity that can open and close to allow food and air to enter the body. Different anatomical structures of the mouth, such as the lips, teeth, tongue, and salivary glands help break down the food.Teeth are a group of partially mineralized anatomical formations  that help break down food with their specialized shapes and hard structures. There are different types of teeth that help accommodate certain movements needed to break down food. For example, there is an incisor tooth at the very front center of the mouth that helps cut out chunks of food. The incisor tooth's flat screwdriver shaped top is what specifically allows the food to be cut into pieces. Molar teeth are located at the back of the mouth where a lot of the grinding motion occurs. Molars have a wide and rugged surface that allows the food to be ground into smaller pieces.In addition to filtering by body location you may also filter by Mouth and Teeth, Blood, Heart and Circulation, Brain and Nerves, Eyes and Vision, Bones, Joint and Muscles, Ear, Nose and Throat, Lungs and Breathing, and lastly Skin, Hair and Nails.
    This page allows you to read up extensively about diseases and drug articles and posts, separated by specific body locations, including Skin, Hair and Nails.This page is organised by alphabetical order, with diseases beginning with the letter A and ending with the letter Z. There is the option to also filter diseases by age group and body systems in addition to body location.The skin primarily acts as a barrier that protects your body from foreign particles and microbes from entering the body. It also keeps necessary fluids, such as water, inside the body.Hairs are thin structures that grow outwards from within the skin. They help keep the body warm and prevent dust particles from entering the eyes. There is hair growing in several areas of the body, such as the scalp, arms, legs, and eyebrows.Nails are flat platelike growths that are found on the tops of fingers and toes. The hard structure of nails help protect the ends of fingers and toes. The nail grows longer because the older cells are pushed outward from the body as new cells are formed. Due to the loss of contact with the nutrient-rich nail bed, the nail turns into an opaque white as the nail grows in length.In addition to filtering by body location lastly Skin, Hair and Nails you may also filter by Blood, Heart and Circulation, Brain and Nerves, Eyes and Vision, Mouth and Teeth, Bones, Joint and Muscles, Ear, Nose and Throat, and Lungs and Breathing.
