Cells Cells are the basic units of all living things Cells are composed of protoplasm Cell reproduction and metabolism takes place in the center nucleus Cytoplasm fluid surrounds the cell for growth, reproduction, repair Anabolism process of building larger molecules from smaller ones Catabolism breaks down compounds into smaller ones to release energy Tissues Connective tissuesupports, protects and binds tissues together Epithelial tissue a protective covering on body surfaces Liquid tissue carries food, waste and hormones thru body Muscular tissue contracts and moves body Nerve tissue carries messages to and from brain 1 Organs & Body Systems Organsgroups of tissues that perform a specific function Body systemsorgans acting together to perform a function Circulatory controls blood circulation thru body Digestive changes food into nutrients and waste; consists of mouth, stomach, intestines, salivary & gastric glands endocrine affects growth, development, sexual activity, body health consists of specialized glands excretory purifies body, eliminates waste, consists of kidneys, liver, skin,intestines, lungs integumentary protective covering regulates body temperature, consists of oil, sweat glands, sensory receptors, hair and nails muscular covers, shapes, and supports skeleton, consists of muscles that contract and move body nervous controls all other systems, consists of brain, spinal cord and nerves reproductiveresponsible for producing offspring respiratory supplies body with oxygen, consists of lungs skeletal foundation of body, consists of 206 bones and joints Osteology study of bones 2 Nervous System Central Nervous System consist of brain, spinal cord, cranial nerves Peripheral nervous system connects outer body parts to central nervous system Autonomic nervous system controls involuntary muscles Sensory nerves carry messages to and from brain Motor nerves carry impulses from brain to muscles 5th Cranial nerve/Trifacial chief sensory nerve of face, controls chewing 7th Cranial/facial nerve chief motor nerve of face, controls facial expression Cervical nerve/11th cranial affect side of neck and platysma muscle Circulatory System Blood vascular system heart, arteries, veins, capillaries Lymph vascular system lymph vessels, lymph nodes & structures; carries waste and impurities from cells Lymph nodes filter blood and fight infections 3
