It receives information through the senses from inside and outside of the body. It analyzes this information then sends messages to the body that controls its functions and actions. The brain remembers past experiences, is the source of thought, moods, and emotions.
Lungs Either of two spongy, saclike respiratory organs in most vertebrates, occupying the chest cavity together with the heart and functioning to remove carbon dioxide from the blood and provide it with oxygen. Diaphragm The main muscle used in the process of inspiration or breathing in.
It is a dome-shaped sheet of muscle that is inserted into the lower ribs. Kidneys A pair of organs functioning to maintain proper water and electrolyte balance, regulate acid-base concentration, and filter the blood of metabolic wastes, which are then excreted as urine. Bladder A hollow muscular organ that stores urine before expelling it from the body. Skeletal Structure.
Organs of the Body. More Information. Circulatory system heart arteries veins capillaries cisterna chyli spleen Lymphatic system a part of the circulatory system thoracic duct right lymphatic duct lymph vessels tonsils, adenoids thymus spleen.
The skin with its associated structures is sometimes considered an organ. Muscular system The individual muscles of the body. Nervous system brain spinal cord peripheral nerves Reproductive system Female: ovaries fallopian tubes uterus clitoris vagina Male: testes vas deferens seminal vesicles prostate penis Respiratory system pharynx larynx trachea bronchi lungs diaphragm Skeletal system The individual bones of the skeleton and associated ligaments and other structures.
The thymus is very active in children and adolescents, and becomes much less active as you grow older. Pancreas — your pancreas is a pistol shaped gland below the liver. It releases digestive enzymes into the small intestine and hormones that control sugar levels in your blood.
Many of the internal organs of the human body. Details. System · Organ systems. Identifiers. Latin, organi. Greek, Οργανο. FMA · · Anatomical terminology. [ edit on Wikidata]. Organs are groups of tissues with similar functions. Plant and animal life relies on many organs. Illustration of the human abdominal organs The abdomen (commonly called the belly) is the body space between the thorax (chest) and.
You can live without a pancreas but you need to take insulin to regulate blood sugar levels and take supplementary digestive enzymes. Skin — your skin is the largest organ in the body. It stops your body from drying out and is the main barrier against infection.
If bone cells are not replaced quickly enough, bones becomes brittle and break more easily. This means that over ten years you have grown and replaced your whole set of bones.

This is because the liver plays a role in recycling red blood cells and their components. For example, during human embryonic development the coronal plane is horizontal, but becomes vertical as the embryo develops into a fetus.

This is called appendicitis.
Most people have two kidneys, but you can survive with just one — or even none with the aid of dialysis. The role of the kidneys is to filter the blood to maintain water and electrolyte balance, as well as the acid-base balance. It does this by acting like a sieve, using a variety of processes to hold onto the useful things, such as proteins, cells and nutrients that the body needs.
There are many reasons people have to have a kidney — or both kidneys — removed: inherited conditions, damage from drugs and alcohol, or even infection. The first uses a machine containing dextrose solution to clean the blood, the other uses a special catheter inserted into the abdomen to allow dextrose solution to be passed in and out manually. If a person is placed on dialysis, their life expectancy depends on many things, including the type of dialysis, sex, other diseases the person may have and their age.
Recent research has shown someone placed on dialysis at age 20 can expect to live for years, whereas someone in their 60s may only live for five years.
