The skin makes up 16% of the body mass and is considered the largest organ. Being 2 mm thick, the skin takes care of protecting the body from germs, pollution, sun radiation, and any other environmental stressors. It also regulates the body’s temperature, receives sensory information, and stores water, vitamin D, and fat.

The functions of the heart are to pump blood and oxygen around the body and deliver waste products (carbon dioxide) back to the lungs to be removed. The heart consists of four chambers, each separated by valves that direct the flow of blood. It lies in the middle of your chest, behind, and slightly to the left of your breastbone.

Tooth decay, also known as cavities or caries, is the breakdown of teeth due to acids produced by bacteria. The cavities may be a number of different colors from yellow to black. Symptoms may include pain and difficulty with eating. Complications may include inflammation of the tissue around the tooth, tooth loss, and infection or abscess formation.

The spleen is a fist-sized organ in the upper left side of your abdomen, next to your stomach and behind your left ribs. It's an important part of your immune system, but you can survive without it. This is because the liver can take over many of the spleen's functions. The spleen has some important functions: it fights to invade germs in the blood (the spleen contains infection-fighting white blood cells); it controls the level of blood cells (white blood cells, red blood cells, and platelets); it filters the blood and removes any old or damaged red blood cells.

You have two lungs, the left lung, and the right lung. The left lung is slightly smaller and has a notch to give room for the heart. Each lung is divided into lobes—the left lung has two and the right lung has three—which are similar to balloons filled with sponge-like tissue. Each lobe receives air from its own branch of the bronchial tree, but they all have the same function: bringing oxygen into the bloodstream and removing carbon dioxide. That's why it's possible (but by no means ideal) to live with just one lung.

The cornea is the transparent part of the eye that covers the front portion of the eye. It covers the pupil (the opening at the center of the eye), iris (the colored part of the eye), and anterior chamber (the fluid-filled inside of the eye). The cornea’s main function is to refract or bend, according to the light. The cornea is responsible for focusing most of the light that enters the eye.

The central nervous system is made up of the brain and spinal cord. The brain is like a central computer that controls all the body's functions. It is in charge of what we think and feel, how we learn and remember, and the way we move and talk. It also controls things we're less aware of — like the beating of our hearts and the digestion of our food. The brain sends messages back and forth with the body. These messages travel through the spinal cord.

The immune system is a network of biological processes that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to parasitic worms, as well as cancer cells and objects such as wood splinters, distinguishing them from the organism's healthy tissue. Many species have two major subsystems of the immune system. The innate immune system provides a preconfigured response to broad groups of situations and stimuli. The adaptive immune system provides a tailored response to each stimulus by learning to recognize molecules it has previously encountered. Both use molecules and cells to perform their functions.

Scoliosis is a sideways curvature of the spine that most often is diagnosed in adolescents. While scoliosis can occur in people with conditions such as cerebral palsy and muscular dystrophy, the cause of most childhood scoliosis is unknown. Most cases of scoliosis are mild, but some curves worsen as children grow. Severe scoliosis can be disabling. An especially severe spinal curve can reduce the amount of space within the chest, making it difficult for the lungs to function properly.

The urinary bladder, or simply bladder, is a hollow organ in humans and other vertebrates that stores urine from the kidneys before disposal by urination. In humans, the bladder is a distensible organ that sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical adult human bladder will hold between 10.14 and 16.91 fl oz before the urge to empty occurs but can hold considerably more.

Permanent cells are cells that are incapable of regeneration. These cells are considered to be terminally differentiated and non-proliferative in postnatal life. This includes neurons, heart cells, skeletal muscle cells, and red blood cells. Although these cells are considered permanent in that they neither reproduce nor transform into other cells, this does not mean that the body cannot create new versions of these cells.

The nephron is the minute or microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule. The renal tubule extends from the capsule. The capsule and tubule are connected and are composed of epithelial cells with a lumen. A healthy adult has 1 to 1.5 million nephrons in each kidney.

Dr John Ngigi, a kidney specialist at KNH, says only the brain can't be transplanted. Reasons range from considerable obstacles in fusing the brain's severed nerve endings to a new spinal cord to establish normal nervous connections between the brain and the new body. Then there is overcoming the new body's inevitable immunological reaction to new tissues besides keeping the brain alive while it is deprived of blood during transplant.

Antennae (sg. antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more joint segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups.

The hippocampus is part of the limbic system, which directs many bodily functions. This system is located in the brain’s medial temporal lobe, near the center of the brain. The hippocampus gets its name from its shape, being the Latin name for a seahorse. It is a complex structure that plays a role in memory, learning, and movement. It also contributes to emotional behavior. In particular, the hippocampus seems to play a major role in declarative memory, the type of memory involving things that can be purposely recalled, such as facts or events.

The ear is the organ in control of the sense of balance. Inside the inner ear is the vestibular system, which is essential for our sense of balance and postural equilibrium. It also coordinates the position of our head with the movement of our eyes. It's made of three semicircular canals, with a space at the end, filled with fluid and small hair cells. Whenever we turn our heads, the inner ear turns along with it, moving the fluid inside and bending the sensory hairs. These hair cells then send information to the brain.

New research reveals how the brain can meet its massive energy demands with a “just in time” system that delivers oxygen that fuels nerve cells. This study demonstrates that microvessels in the brain play a key role in reacting to spikes in demand and accelerating the blood flow to respond to neuronal activity. Energy in the brain is generated almost exclusively from a form of metabolism that requires oxygen. The brain’s oxygen demands are enormous; despite comprising only 2 percent of the body, our brains consume 20 percent of the body’s oxygen supply.

The occipital bone is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull). It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone overlies the occipital lobes of the cerebrum. At the base of the skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord.
