| Term | Definition |
|---|---|
| integumentary | system referring to the skin, hair and nails |
| circulatory system | (aka cardiovascular system) This system works as the transportation highway for the body. It consists of the heart, blood, and blood vessels. It transports substances such as oxygen, carbon dioxide, and nutrients in the body. |
| muscular system | Consists of skeletal muscles, tendons that connect muscles to bones, and ligaments that attach bones together to form joint, participates in heat production |
| digestive system | body system that breaks down food and absorbs nutrients |
| urinary system | kidneys, ureters, urinary bladder, urethra also helps regulate blood volume and pressure |
| nervous system | system charged with the control, regulation and coordination of other systems as well as sensation and memory |
| lymphatic system | produces immune cells |
| reproductive system | system of organs involved in producing offspring including testes, seminal vesicles, ovaries, faliopian tubes |
| respiratory system | system responsible for taking in oxygen and releasing carbon dioxide using the lungs includes the nose, pharynx, larynx, taches, bronchi and lungs |
| endocrine system | Consists of glands that control many of the body's activities by producing hormones. |
| skeletal system | Protects and supports body organs and provides a framework the muscles use to support movement. Made up of bones and joints key role in blood formation. |
| arm | brachial |
| lower back | lumbar |
| armpit | axillary |
| heel | calcaneal |
| fingers | digital |
| shoulder | deltoid |
| sole of foot | plantar |
| forehead | frontal |
| chest | sternal |
| front of elbow | antecubital |
| foot | pedal |
| cheek | buccal |
| groin | inguinal |
| ankle | tarsal |
| 4 elements that make up 96% of the body | oxygen, carbon, hydrogen, nitrogen |
| Makes up the greater percentage of the body's weight | oxygen |
| metabolism | All of the chemical reactions that occur within the body |
| why water is important | lubricates many body tissue |
| normal PH of blood | 7.35-7.45 |
| plasma membrane | proteins embedded in the cell wall acts as channels |
| forms the bulk of plasma membrane | phospholipids |
| develops in a solution as the result of osmosis | osmotic pressure |
| action of the sodium potassium pump | works to transfer sodium from inside to outside the cell while transferring potassium from outside to inside the cell |
| type of tissue that covers the body's surface | epithelial |
| bone, cartilage and adipose tissue are all types of | connective tissue |
| The heart is located in the _____ cavity | thoracic |
| Pain in Right Hypochondriac Region | gallbladder |
| adding and removing elements from an atom result in the formation of | iron |
| factor that differentiates one element from another | number of protons |
| causes atom to emit radiation | unstable isotopes emit radiation as they decay |
| towards the midline | medial |
| away from the midline | lateral |
| farthest from the point of origin | distal |
| closest to the point of origin | proximal |
| above | superior |
| toward the front of the body | anterior |
| toward back of the body | posterior |

| away from the body surface | deep |
| below | inferior |
| divides the body lengthwise into right and left portions. | sagittal |
| divides body horizontally | transverse plane |
| divides the body into anterior and posterior portion | frontal |
| two major cavities | dorsal and ventral |
| receives info/change in environment | receptor |
| receives and processes the information supplied by the receptor and sends out commands | control center |
| Responds to signalsRe | effector |
| opposes stimulus and reverse direction of change | negative feedback |
| reinforces a stimulus to produce an even greater response | positive feedback |
| anything that has mass and takes up space | matter |
| pure substance | elements |
| chemical compound of 2 or more elements | compounds |
| consist of particles called atoms | elements |
| tiny particles with negative charge | electrons |
| protons and neutrons packed together in the center of atoms | nucleus |
| particle composed of 2 or more atoms united by a chemical bond | molecule |
| Largest molecules in the body | DNA |
| boundary of the cell | plasma membrane |
| gel like substance | cytoplasm |
| short rod like structures | chromosmes |
| performs tasks for which it was created | first gap phase |
| makes or synthesizes extra set of DNA | synthesis phase |
| final preparation for cell division | second gap phase |
| cell division occurs | mitotic phase |
| atom of an element that contains a different number of neutrons | isotope |
| energy of motion | kinetic |
