| what word means below or closer to the feet | inferior or caudal |
| what word means toward the front of the body | anterior or ventral |
| what word means toward the back of the body | posterior or dorsal |
| What word means close to the midline of the body | medial |
| what word means further away from the midline of the body | lateral |
| what word means closer to the trunk of the body | proximal |
| What word means father away from the trunk | distal |
| what word means closer to the surface of the body | superficial |
| what word means farther from the bodies surface | deep |
| directional term that Divides the body into left and right sides. | sagittal plane |
| Directional term that divides the body into left and right sides running thru the midline. | midsagittal plane |
| directional term that divides the body into upper and lower sections, not always equally is: | transverse plane |
| also called the coronal plane, divides the body into anterior and posterior sections: | frontal plane |
| what body cavity houses the meninges/ | cranial cavity |
| What cavity connects to the cranial cavity and runs down the midline? | spinal cavity |
| what cavity houses the lungs, heart and major vessels | thoracic cavity |
| This houses the several major organs | abdominal cavity |
| this cavity houses the reproductive tract and bladder | pelvic cavity |
| RUQ | right upper quadrant |
| LUQ | left upper quadrant |
| RLQ | right lower quadrant |
| LLQ | Left lower quadrant |
| When the body is at a balanced stable state it's called: | homeostasis |
| What is responsible for protection, sensation, temperature regulation, and vitamin D production? | Skin |
| what Produces sebum | sebaceous oil glands |
| finger nails and toe nails are meant to: | protect fingertip and toes |
| This aids in the cooling of the body: | sudoriferous glands |
| outer layer of epithelial cells is: | epidermis |
| thick layer under the dermis that contains arteries, veins, and nerves is the: | Dermis layer |
| loose connective tissue composed of adipose tissue and lipocytes is the: | subcutaneous layer |
| 80 bones including the skull, vertabrae, and ribs is what type of skeleton? | axial skeleton |
| what type of skeleton contains 126 bones including arms, legs, and pelvic girdle | appendicular skeleton |
| these attach bone to bone | ligaments |
| these bones have yellow bone marrow and are covered by articular cartilage | long bones |
| these bones are small and round | short bones |
| skull and rib bones are what type of bone shape? | flat bones |
| vertebrae and pelvis bones are considered: | irregular bones |
| small round bones in joints held by tendons are called | sesamoid bones |
| This muscle type is responsible for movement: | skeletal, striated, or voluntary this muscle |
| this muscle is found within hollow organs, and blood vessels | smooth or involuntary |
| this muscles is cross fibered to allow for contracting | cardiac muscle |
| Small granular structures concentrated in the axilla, neck, and groin are | lymph nodes |
| masses comprised of macrophages and lymphocytes but not encapsulated are: | lymph nodules |
| located posterior to the sternum responsible for producing T-cells is: | thymus |
| located in the upper left abdominal quadrant home to macrophage that filter the blood is: | the spleen |
| A major component of the bodies defense are: | T cells and B cells |
| This is a foreign substance in the body | antigen |
| the protein the body creates in response to specific antigens in the body are: | antibodies |
| antibodies are also called: | immunoglobulins |
| These are lymphocytes that recognize antigens and respond by turning into plasma that create antibodies against a certain antigen are: | B cells |
| these are lymphocytes that recognize antigens and attaches and destroys them: | Killer T cells |
| these engulf and destroy coagulated pathogens in the blood with antibodies | Monocytes |
| This type of immunity occurs when a host has an infection and develops antibodies to prevent future infections | naturally acquired active immunity |
| this type of immunity comes from a vaccine | artificially acquired active immunity |
| This immunity is short term usually passed from mother to newborn | naturally acquired passive immunity |
| this immunity is short term and is done by giving an exposed person antibodies from a person who had the infection already | artificially acquired passive immunity |
| these are thick walled vessels that carry blood away from the heart and contract to move the blood. | artery and arteriole |
| These vessels carry blood to the heart and contain valves | veins and venule |
| these are the smallest of vessels that aid in the exchange of oxygen and nutrients between blood and body cells | capillary |
| this is the inner most layer of cells that line the atria and ventricles | endocardium |
| this is the muscular layer of the heart | myocardium |
| this is a membrane surrounding the heart producing pericardial fluids | pericardium |

| This organ is an expandable sac | urinary bladder |
| this tube is responsible for excreting urine | urethra |
| this body part is responsible for initial digestion | mouth |
| this is a part of the gastrointestinal and respiratory systems | pharynx |
| muscular tube that uses wave like movements called peristalsis | esophagus |
| uses gastric juices to break down food and propels it to the small intestine | stomach |
| this organ takes up most of the abdominal space and absorbs nutrients | small intestine |
| small intestine has 3 sections: | duodenum, jejunum, ileum |
| absorption is completed here and feces is formed here | colon |
| colon has 5 sections which are | cecum, ascending, transverse, defending, and sigmoid colon |
