Energy is produced by burning molecules in food, which is done by the process of oxidation whereby food molecules are combined with read more filter out particles that are present in the air that is inhaled. The walls of the passages in the nose and airways are coated with mucus.
Microorganisms in the air become stuck to the mucus, which is coughed up or blown out of the nose. Mucus removal is aided by the coordinated beating of tiny hairlike projections cilia that line the airways.
The cilia sweep the mucus up the airways, away from the lungs. The digestive tract Overview of the Digestive System The digestive system, which extends from the mouth to the anus, is responsible for receiving food, breaking it down into nutrients a process called digestion , absorbing the nutrients into read more has a series of effective barriers, including stomach acid Stomach The stomach is a large, bean-shaped, hollow muscular organ consisting of four regions: Cardia Fundus Body Antrum read more , pancreatic enzymes Pancreas The pancreas is an organ that contains two types of glandular tissue: Pancreatic acini Islets of Langerhans See also Overview of the Digestive System.
The acini produce digestive enzymes read more , bile Gallbladder and Biliary Tract The gallbladder is a small, pear-shaped, muscular storage sac that holds bile and is interconnected to the liver by ducts known as the biliary tract. See also Overview of the Liver and Gallbladder read more , and intestinal secretions.
These substances can kill bacteria or prevent them from multiplying. The contractions of the intestine peristalsis, which moves contents of the bowel through the digestive tract , and the normal shedding of cells lining the intestine help remove harmful microorganisms.
The urinary tract Overview of the Urinary Tract Normally, a person has two kidneys. The rest of the urinary tract consists of the following: Two ureters the tubes connecting each kidney to the bladder The bladder an expandable muscular read more also has several effective barriers.
The bladder is protected by the urethra Urethra The urethra is a tube that drains urine from the bladder out of the body. In men, the urethra is about 8 inches 20 centimeters long, ending at the tip of the penis.
In women, the urethra is read more , the tube that drains urine from the body. In males, the urethra is long enough that bacteria are seldom able to pass through it to reach the bladder, unless the bacteria are unintentionally placed there by catheters or surgical instruments.
In females, the urethra is shorter, occasionally allowing external bacteria to pass into the bladder. In both sexes, when the bladder empties, it flushes out any bacteria that reach it.
The vagina Vagina The internal genital organs form a pathway the genital tract. This pathway consists of the following: Vagina part of the birth canal , where sperm are deposited and from which a baby can read more is normally acidic. The acidity of the vagina Causes Bacterial vaginosis is a common condition that occurs when the balance of bacteria in the vagina vaginal microbiome is altered.
Bacterial vaginosis causes a thin, yellow-green or gray discharge read more prevents harmful bacteria from growing and helps maintain the number of protective bacteria. The body also defends against infection by increasing the number of certain types of white blood cells neutrophils Neutrophils One of the body's lines of defense immune system involves white blood cells leukocytes that travel through the bloodstream and into tissues, searching for and attacking microorganisms and read more and monocytes Monocytes and Macrophages One of the body's lines of defense immune system involves white blood cells leukocytes that travel through the bloodstream and into tissues, searching for and attacking microorganisms and read more , which engulf and destroy invading microorganisms.
The increase can occur within several hours, largely because white blood cells are released from the bone marrow, where they are made. The number of neutrophils increases first.
If an infection persists, the number of monocytes increases. The blood carries white blood cells to sites of infection. Mechanisms of immune defense are also utilized to identify and eliminate neoplastic tumor cells.
The task of innate immunity is to respond rapidly to challenges by Michael U. Until recently, immunoglobulin therapy in Australia mostly involved delivery of immunoglobulins through a drip into the vein — known as intravenous immunoglobulin IVIg therapy. Now, subcutaneous immunoglobulin SCIg therapy External Link can be delivered into the fatty tissue under the skin, which may offer benefits for some patients.
This is known as subcutaneous infusion or SCIg therapy. Subcutaneous immunoglobulin is similar to intravenous immunoglobulin. It is made from plasma — the liquid part of blood containing important proteins like antibodies. Download the Subcutaneous Immunoglobulin - information sheet for patients External Link to read more about this type of treatment.
Many health services are now offering SCIg therapy to eligible patients with specific immune conditions. Immunisation works by copying the body's natural immune response. A vaccine a small amount of a specially treated virus, bacterium or toxin is injected into the body. The body then makes antibodies to it.
If a vaccinated person is exposed to the actual virus, bacterium or toxin, they won't get sick because their body will recognise it and know how to attack it successfully. Vaccinations are available against many diseases, including measles and tetanus.
The immunisations you may need are decided by your health, age, lifestyle and occupation. Together, these factors are referred to as HALO, which is defined as:. View the HALO infographic External Link to find out more. This page has been produced in consultation with and approved by:.

Immune system The immune system is made up of a complex network of organs, cells and proteins that fight infection microbes. The immune system and microbial infection The immune system External Link keeps a record of every microbe it has ever defeated, in types of white blood cells B-lymphocytes and T-lymphocytes known as memory cells.
Parts of the immune system The main parts of the immune system are: white blood cells antibodies complement system lymphatic system spleen bone marrow thymus. White blood cells White blood cells are the key players in your immune system. Antibodies Antibodies help the body to fight microbes or the toxins poisons they produce.
Complement system The complement system is made up of proteins whose actions complement the work done by antibodies. Lymphatic system The lymphatic system is a network of delicate tubes throughout the body. The main roles of the lymphatic system are to: manage the fluid levels in the body react to bacteria deal with cancer cells deal with cell products that otherwise would result in disease or disorders absorb some of the fats in our diet from the intestine.

The innate immune Leafy green industry consists sysyem physical, chemical Immune system defense edfense defenses against pathogens. The main purpose of the innate immune response is to immediately prevent the spread and movement of foreign pathogens throughout the body. The second line of defense against non-self pathogens is called adaptive immune response. Adaptive immunity is also referred to as acquired immunity or specific immunity and is only found in vertebrates.
