Period Ch. 21 -Unifying Concepts of Animal Structure and Function is the study of the structure of an organism is the study of the functions of an organism; how it works 3 What is the correct structural hierarchy? is a group of similar cells that perform a specific function tissue eccurs as sheets of tightly packed cells that cover body surfaces and line intenal organs and cavities epithelium would he a single layor of cells as tall as they are wide. epithelium would be more than one layer of flat oells epithelium would be more than one layer of scale-like cells is epithelial tissue lining our digestive & respiratory tracts that secretes mucous to keep it tissue is a sparse population of oells in an extracellular matrix binds and packs material, it holds organs in place tisue (fat) pads and insulaties the body. It also stores energy consists of cells (red and white) in a fluid matrix (plasma) 10. 12. 13. It transports materials around the body 14. t fonms tendons that hold muscies to bones and ligaments that hold bones to bones. 15. 16. has a matrix of densely packed parallel bundles of collagen fibers forms a strong but flexible material with several functions related to the skeleton tissue is a rigid matrix of collagen fibers with calkium salts. tissue consists of bundles of long muscle fibers tissue is the most common type of tissue in a vertcbeates. 19. muscle is atlached to the skeleton (by tendons) and allows us to move. muscle forms the heart mascle is found in the internal organs. 21. tissue forms a coemmunications system to transmit nerve signals around the body 23. The basic nerve cell is called a usually travel from one place to another by a chain of ncurons, each passing the signal to the next one. 25. provides 360 X-rays of the body which are picced topether with a computer to give 3-D views s used to exchange materials between blood and the body. 27. As extenmal conditions change, animals regulate their intermal environment to maintain is a system where the body senses when a cortain level is reached and stops an action. The 11 basic body systems: physiology .ingests food and breda it down i to smaller chemical units 29. Skeletal 30,Nervo@ .produces the sex cells and (in wonnen) allows for the prodation ofofhpring 31. Reprodactive C.coordinates body activities 2. Muscular D.transports nutrients & oxypen to the body cells and takes wastes away for removal 33. Respiratory E. produces hormones to affect metabolic activities 34. Circulatory F helps circulate materials throughout the body 35. Integumentary G.filkers wastes from the bHood 36. Digestive H provides support and protection 37. Lymphatic L allows us to move and perform certain body activities 38. Endocrine Jexchanges gases with the environment (takes in oxygen, relcases carbon dioxide) 39. Urinary K.prolects the body The 11 basic body systems: anatommy 40. Respiralory A glands such as the pancreas, pituitary, thyroid, adrenal, etc. 41. Digestive B ovaries or testes, uterus (in women) 42. Endocrine C.kidneys, ureters, bladder, and urethra 43. Circulatory D bones, tendons, ligaments, cartilage 44. Skeletal Eskin, hair, nails, interior linings 45. Muscular F. brain, spinal cord, nerves 46. Nervous G.skeletal, cardiac, and smooth muscles 47. Reproductive IL oral cavity, esophagus, stomach, small& large intestines 48 Lymphatic I nasal cavity, laryns, trachea, and hungs 49. Integumentary J. heart, blood, blood vessels 0. Urinary K. lymph, lymph vessels, lymph nodes, spleetExplanation / Answer
