Organ System Flashcards
Nervous System
enables animals to send, receive, and process nerve and sensory impulses
Reproductive System
enables animals to produce offspring
Central Nervous System
the brain and spinal cord
Peripheral Nervous System
the nerves that branch off of the brain and spinal cord and carry nerve signals to muscles and glands
Autonomic Nervous System
controls involuntary actions such as heartbeat and digestion
Circulatory System
transports blood throughout an animal’s body and carries away waste products
Respiratory System
respiratory system brings air into the animal and releases waste carbon dioxide back into the air
Lymphatic System
helps to filter out disease-causing organisms and helps to drain fluid waste from in and around tissues
Endocrine System
made up of glands (such as the thyroid, pituitary, parathyroid adrenal, pineal body, pancreas, thymus, ovaries, and testes) and hormones (chemicals released from glands into the bloodstream). glands and hormones control or influence various body functions (such as metabolism, growth, and reproduction)
Urinary System
consists of the kidneys, bladder, ureters, and urethra and enables animals to expel waste fluids in the form of urine
Muscular System
consists of skeletal muscles which help move the skeleton and control movement, smooth muscles which are involuntary and control the stomach and intestine, and cardiac muscles which include the heart muscles
Digestive System
enables animals to break down food that they eat and obtain energy for other body processes
Integumentary System
animal’s outer covering (such as skin, scales, feathers, fur, and other body parts that protect the animal and prevent it from drying)
Immune System
protects against infection and disease, contains both bone marrow and the thymus, organs involved with the immune system are called the Lymphoid organs
Skeletal System
provides internal or external support (such as a skeleton, exoskeleton or shell)
