An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ system does a particular job in the body, and is made up of certain tissues.
Organs systems and their functionsEdit
These specific systems are widely studied in anatomy. They are present in many types of animals.
- Respiratory system: the organs used for breathing, the pharynx, larynx, bronchi, lungs and diaphragm.
- Digestive system: digestion and processing food with salivary glands, esophagus, stomach, liver, gallbladder, pancreas, intestines, rectum and anus.
- Cardiovascular system (heart and circulatory system): and channeling blood to and from the body and lungs with heart, blood and blood vessels.
- Urinary system: kidneys, ureters, bladder and urethra involved in fluid balance, electrolyte balance and excretion of urine.
- Integumentary system: skin, hair, fat, and nails.
- Skeletal system: structural support and protection with bones, cartilage, ligaments and tendons.
- Endocrine system: communication within the body using hormones made by endocrine glands such as the hypothalamus, pituitary gland, pineal gland, thyroid, parathyroid and adrenal glands.
- Lymphatic system: the transfer of lymph between tissues and the blood stream; includes the lymph and the nodes and vessels. Includes the functions of immune responses and the development of antibodies.
- Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The job of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide, and hormones, around the body. It consists of the heart, blood, blood vessels, arteries and veins.
- Immune system: protects the organism from foreign bodies.
- Nervous system: collecting, transferring and processing information with brain, spinal cord, peripheral nervous system and sense organs.
- Muscular system: allows for manipulation of the environment, provides locomotion, maintains posture, and produces heat. Includes skeletal muscles, smooth muscles and cardiac muscle.
- Reproductive system: the sex organs, such as ovaries, fallopian tubes, uterus, vagina, mammary glands, penis, testes, vas deferens, seminal vesicles and prostate.
