Definition of Anatomy: | The Structures of the Body |
Definition of Physiology | Is the study of functions of anatomical structures. |
How are living things organized? | From simple to complex: Atoms, Molecules, organelles,Cells, Tissues, Organs, Organ System, Organism |
What are the 11 organ systems? | Integumentary, Lymphatic, Respiratory, Digestive, Urinary, Reproductive, Muscular, Skeletal, Nervous, Endocrine, and Circulatory |
Circulatory System includes and does what? | Heart, Blood, and Blood Vessels. Primarily a transport system that carries blood and other substances to and from the tissue cells. |
Digestive System includes and does what? | Oral cavity,esophagas, stomach, small/large intestines, and accessory structures. Breaks down ingested food. |
Endocrine System includes and does what? | thymus, thyroid, ovaries, testes, and pancreas Helps maintain body homeostasis, promotes grown and development. |
Integumentary System includes and does what? | Epidermal and Dermal regions Protects deeper organs, aids in regulation of body temp, produces vitamin D |
Lymphatic System includes and does what? | Spleen,thymus,tonsils clean blood, pick up fluid leaked from blood vessels and returns it to the blood. |
Muscular System includes and does what? | Muscles Primary function is to contract or shorten. |
Nervous System includes and does what? | Brain, Spinal cord, nerves, and sensory receptors Helps body to detect changes and to respond and helps maintain homeostasis of the body |
Reproductive System includes and does what? | Male:testes, prostate gland, scrotum, penis, and duct system. Female: Ovaries uterine tubes uterus, mammary glands, and vagina. |
Respiratory System includes and does what? | Nasal passages, Pharynx, larynx trachea, bronchi, and lungs. Keeps blood continuously supplied with oxygen while removing carbon dioxide. |
Skeletal System includes and does what? | bones, cartilages, tendons, ligaments, and joints body support and protection of internal organs. |
Urinary System includes and does what? | Kidneys, ureters, bladder, and urethra Rids body of waste |
Homeostasis | The processes used to maintain body equilibrium. |
Negative Feedback | The response of the effector negates the stimulus (re-set) |
Positive Feedback | The response of the effector reinforces/exaggerates the stimulus. |
