About biology
Welcome to the biology portal. Biology, from the Greek words bios (life) and the suffix -ology, meaning study of, is a branch of science. It is concerned with the characteristics and behaviors of organisms, how species and individuals come into existence, and the interactions they have with each other and with their environment. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. Together, they study life over a wide range of scales. Blue has been chosen as the colour for this portal to emphasise that life on Earth relies on the unique chemistry of water. A photo of Darlingtonia californica, the cobra lily, was chosen as the portal icon because of this species' dependency on a humid habitat, as well as illustrating both autotrophy (in this case, photosynthesis) and carnivory. Finally, they superficially resemble young shoots, with their tips curved in, symbolising growth, a feature of all life.

Major organ systems

 * Circulatory system: pumping and channeling blood to and from the body and lungs with heart, blood, and blood vessels.
 * Digestive system: digestion and processing food with salivary glands, esophagus, stomach, liver, gallbladder, pancreas, intestines, rectum, and anus.
 * Endocrine system: communication within the body using hormones made by endocrine glands such as the hypothalamus, pituitary or pituitary gland, pineal body or pineal gland, thyroid, parathyroids, and adrenals or adrenal glands
 * Integumentary system: skin, hair and nails
 * Lymphatic system: structures involved in the transfer of lymph between tissues and the blood stream, the lymph and the nodes and vessels that transport it including the Immune system: defending against disease-causing agents with leukocytes, tonsils, adenoids, thymus, and spleen
 * Muscular system: movement with muscles.
 * Nervous system: collecting, transferring and processing information with brain, spinal cord, peripheral nerves, and nerves
 * Reproductive system: the sex organs, such as ovaries, fallopian tubes, uterus, vagina, mammary glands, testes, vas deferens, seminal vesicles, prostate, and penis.
 * Respiratory system: the organs used for breathing, the pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
 * Skeletal system: structural support and protection with bones, cartilage, ligaments, and tendons.
 * Urinary system: kidneys, ureters, bladder and urethra involved in fluid balance, electrolyte balance and excretion of urine.
