Chemical/ Molecular Level Atoms, the smallest stable unit of matter, form molecules The shape of the molecule determines its function 2. Cellular Level Molecules form organelles Each type of organelle performs a specific function Organelles together make up a cell, the smallest living unit 3. Tissue Level A tissue is a group of cells working together to perform one or more specific functions 4. Organ Level An organ is two or more tissues working together to perform several functions 5. Organ System Level An organ system involves the interaction of multiple organs to achieve common goals (11 organ systems, see on reverse) 6. Organism (Human) Level Organ systems work together to maintain the life and health of the body Amy Warenda Czura, Ph.D.3SCCC BIO130 Chapter 1 HandoutOrgan System Overview Integumentary System Protects against the environment and helps control body temperature Skeletal System Provides support, protects tissues, stores minerals, and makes blood Muscular System Produces movement and locomotion, provides support, and generates heat Nervous System Directs immediate response to stimuli by coordinating activities of other organ systems Endocrine System Directs long term changes in other organ systems via hormones Cardiovascular System Transports cells and dissolved materials including wastes and gases Lymphatic System Defends against infection and disease, and returns tissue fluid to the bloodstream Respiratory System Delivers air to sites where gas exchange can occur between air and circulating blood Digestive System Processes food, absorbs nutrients, and eliminates waste products Urinary System Eliminates excess water, salts, and waste products Reproductive System Produces sex cells and hormones Amy Warenda Czura, Ph.D.4SCCC BIO130 Chapter 1 HandoutAnatomical regionsAmy Warenda Czura, Ph.D.5SCCC BIO130 Chapter 1 HandoutPlanes of SectionDirectional TermsBody CavitiesAmy Warenda Czura, Ph.D.6SCCC BIO130 Chapter 1
