Urinary System :) Movies, quizzes, and health info for kids: KidsHealth.org. Your Digestive System. Urinary System: Facts, Functions & Diseases. The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys.
The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder. When the bladder is full, a person urinates through the urethra to eliminate the waste. The urinary system is susceptible to a variety of infections and other problems, including blockages and injuries. These can be treated by a urologist or another health care professional who specializes in the renal system. Muscular System: Facts, Functions & Diseases. While most people associate muscles with strength, they do more than assist in lifting heavy objects.
The 650 muscles in the body not only support movement — controlling walking, talking, sitting, standing, eating and other daily functions that people consciously perform — but also help to maintain posture and circulate blood and other substances throughout the body, among other functions. Muscles are often associated with activities of the legs, arms and other appendages, but muscles also produce more subtle movements, such as facial expressions, eye movements and respiration, according to the National Institutes of Health (NIH).
Skeletal System: Facts, Function & Diseases. The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them.
The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive. Animals with internal skeletons made of bone, called vertebrates, are actually the minority, as 98 percent of all animals are invertebrates, meaning they do not have internal skeletons or backbones. Human infants are born with about 270 bones, some of which fuse together as the body develops. By the time we reach adulthood, we have 206 bones, according to Arizona State University’s School of Life Sciences. Circulatory System: Facts, Function & Diseases. The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells.
Without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment — such as proper temperature and pH — known as homeostasis. While many view the circulatory system, also known as the cardiovascular system, as simply a highway for blood, it is made up of three independent systems that work together: the heart (cardiovascular); lungs (pulmonary); and arteries, veins, coronary and portal vessels (systemic), according to the U.S National Library of Medicine (NLM).
In the average human, about 2,000 gallons (7,572 liters) of blood travel daily through about 60,000 miles (96,560 kilometers) of blood vessels, according to the Arkansas Heart Hospital.

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide.
The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed, according to the American Lung Association. Nervous System: Facts, Function & Diseases. The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body.
It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. According to the National Institutes of Health, the central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system. Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component; and the autonomic, or involuntary, component.
Immune System: Diseases, Disorders & Function. The role of the immune system — a collection of structures and processes within the body — is to protect against disease or other potentially damaging foreign bodies.
When functioning properly, the immune system identifies a variety of threats, including viruses, bacteria and parasites, and distinguishes them from the body's own healthy tissue, according to Merck Manuals. Lymph nodes: Small, bean-shaped structures that produce and store cells that fight infection and disease and are part of the lymphatic system — which consists of bone marrow, spleen, thymus and lymph nodes, according to "A Practical Guide To Clinical Medicine" from the University of California San Diego (UCSD).
Lymph nodes also contain lymph, the clear fluid that carries those cells to different parts of the body. Integumentary System. Introduction The integumentary system consists of the skin, hair, nails, glands, and nerves.
Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. In order to do these things, the integumentary system works with all the other systems of your body, each of which has a role to play in maintaining the internal conditions that a human body needs to function properly.

How Your Body is Like a Factory. Did you know that you can actually hear pulmonary circulation?
Pulmonary circulation is the movement of blood though the right side of the heart, to the lungs, and then back through the left side of the heart. The “lub dub” you hear when using a stethoscope is the sound of the ventricles contracting and the heart valves closing during this circulation process. Blood takes a very precise route during pulmonary circulation. Two large veins called the vena cavae bring blood to the right atrium of the heart.
