Two or more organs work together to form an organ system. Various types of organ systems include the skeletal system, the circulatory system, the muscular system, the digestive system, the endocrine system, and the respiratory system.
Functions of digestive system are procuring , mastication ,digestion and absorbing the food that we eat. What we can't digest is eliminated as waste. The organs in the digestive system include oral cavity , pharynx, esophagus, stomach, small intestine, large intestine.
The Human Organ Systems are: (in brief)
Integumentary System: Skin. Largest organ system. Protects, regulates body temperature, holds water, excretes waste, has sensory receptors, and synthesizes biochemicals.
Skeletal System: Bones. Attach to muscles, protects, structure, produces blood, store salts, and houses blood vessels/nerves.
Muscular System: Muscles. Movement, structure, heat, controls heart. 3 Types: Skeletal, cardiac, and smooth muscle.
Nervous System: Controlled in the brain, sensors throughout the entire body. Provides feelings, thoughts, movement, consciousness. Afferent and efferent fibers.
Endocrine System: Secretes hormones.
Cardiovascular System: The heart. Transports blood and oxygen around the body. Excreting wastes.
Lymphatic System: Takes excess fluids, transports fluid, absorb fats, attacks foreign cells/cancer/toxins.
Respiratory System: Lungs, nasal/oral cavities. Supplies oxygen to the body.
Urinary System: Kidneys, ureters, bladder, urethra. Removes wastes from body, maintains water concentration.
Reproductive System: Males- penis, testes, and sperm. Female: vagina, ovaries, eggs, breasts.
Levels of Organization (smallest to largest):
Atoms: smallest form.
Molecules: bonded atoms.
Macromolecules: completely bonded molecules.
Cell: basic structure of life.
Organelles: many cells which are specialized.
Tissue: organelles which have the same function come together.
Organs: Tissues which come together to form specialized functions.
Organ System: A group of organs working together.
Organism: A full being made up of many organ systems.

A group of organisms that perform a related task is called an organ system. An example would be the digestive system, which includes the esophagus, stomach, liver, gallbladder, pancreas, small intestine, and large intestine. Another example is the nervous system, which includes the brain and nerves.
A group of organs that work together to perform a specific job in the body is called a system. Each system serves one or more functions. For example, different hormones are secreted by different glands, but work together and provide feedback to each other to control their effects.

Your imune systems organisms, they work together to fight off infectious colds and viruses.
Group of living things plus the environment they live in forms an ecosystem.

a group of cells that work together to preform a function are called tissues. A group of tissues that work together to preform a function are called Organs.
A group of persons who work, play, or act together could be called a team or group. In the workplace, they might be called a work group.
what are weels working together in a system are called
Groups of cells that work together are called tissues.
A group of tissues that work together doing certain jobs is an organ.
