| a tough, flexible band of connective tissue that holds bones together at a joint | ligament |
| the microscopic unit of compact bone | osteon |
| where two bones are fused together | immovable joint |

| when bones act like a rigid bar turning on a fulcrum act as a __________. | lever |
| what is contained in the central cavity of a bone | marrow |
| what is formed from additional cells/layers as a result of friction to protect the deeper layers of the skin? | callus |
| type of gland for cooling and excretion of wastes | sweat |
| the layer below the skin which is not really part of the skin | subcutaneous layer |
| the type of tissue the epidermis is made of | epithelial tissue |
| type of gland next to each hair follicle | oil gland |
| functions of the subcutaneous layer | support, cushioning, insulation |
| the study of the organs and structures of the body | anatomy |
| the study of how organs and structures function | physiology |
| What are the four levels of organization in the human body starting with the lowest level? | cells-->tissues-->organs-->systems |
| Cells work together to make up tissues | tissues work together to make organs |
| tissue that supports, connects, and protects other body structures | connective tissue |
| a small opening in the epidermis that releases oil onto the skin surface | pore |
| very hard bone made of circular layers | compact bone |
| the material at the center of some bones that produces blood cells | bone marrow |
| a band of connective tissue that attaches muscle to bone | tendon |
| another name for a voluntary muscle | skeletal muscle |
| a muscle that has a pattern of dark and light bands, called striations, found in both skeletal and cardiac muscles | striated muscle |
| a muscle that is not controlled at will | involuntary muscle |
| a striated, involuntary muscle found in the heart | cardiac muscle |
| tissue that receives and transmits electrochemical impulses to coordinate the functions of the body | nerve tissue |
| tissue that contracts either to move the body or to move substances through the body | muscle tissue |
| hard and rigid bone with empty spaces throughout | spongy bone |
| the connection between two or more bones | joint |
| the organ system that an animal or human uses to move around | muscular system |
| an involuntary muscle without striations found in internal organs | smooth muscle |
| the study of the organs and structures of the body | Anatomy |
| the study of how organs and structures function | Physiology |
| a body tissue that carries messages back and forth between the brain and every other part of the body | nerve tissue |
| A body tissue that contracts or shortens, making body parts move. | muscle tissue |
| A body tissue that covers the surfaces of the body, inside and out | epithelial tissue |
| a small tubular cavity containing the root of a hair | hair follicle |
| the organ system that an animal or human uses to move around | Muscular System |
| a muscle that is controlled at will | voluntary muscle |
| Connects muscle to bone | Tendon |
| A muscle that is attached to the bones of the skeleton and provides the force that moves the bones. | skeletal muscle |
| Which system consists of the skin, hair, and nails | integumentary system |
| Which system supplies the body with energy by breaking down and absorbing food and eliminating wastes? | digestive system |
| Which system protects the internal organs and supports the body? | Skeletal system |
| Which system provides movement by pulling on the bones, causing them to move? | muscular system |
| Which system transports blood? | circulatory system |
| Which system eliminates certain types of wastes and maintains the right amount of water in the body? | urinary system |
| Which system exchanges oxygen with carbon dioxide in the blood stream? | respiratory |
| Which system besides the what involves the skin helps protect the body from threats such as viruses and bacteria? | lymphatic system |
| Which system coordinates and controls movement and processes information? | nervous system |
| Which system consists of the glands that secrete chemicals that regulate body functions? | endocrine system |
| Which system creates and protects new human life? | reproductive system |
| Which system is the lymphatic system part of? | immune system |
| How are humans different from mammals? | created in the image of God--having immortal souls, and the ability to distinguish right/wrong |
