What are the 3 main part of a cell? | 1)nucleus 2)cytoplasm 3)cell membrane |
nucleus | directs the activities of the cell, like a command center. It directs the growth of the cell and cell division |
chromosomes | threadlike structures that carry DNA |
cytoplasm | material surrounding the nucleus of a cell |
metabolism | process of the living cell in which oxygen is used and carbon dioxide is given off (called the work of the cell) |
Tissue | group of the same type of cells functioning in the same way |
What are 5 categories that tissues are grouped into? | 1)epithelial 2)connective 3)nervous 4)blood and lymph 5)muscular |
cell membrane | the edge of the cell. It keeps the protoplams in but allows certain other materials to pass in and out of the cell. |
metabolism | process of the living cell in which oxygen is used and carbon dioxide is given off (called the work of the cell) |
Organ | (tissues combine to form it) it is a body part where two or more tissues work together to perform a particular function |
System | consist of a group of organs that perform the same function. |
Name the body systems | 1)integumentary 2)digestive 3)skeletal 4)respiratory 5)muscular 6)circulatory 7)nervous 8)endocrine 9)urinary 10)reproductive |
What happens when cancer invades the cell's normal mechanisms that control rate of growth? | cell division and movements are destroyed. |

External therapy | a machine bemas high-energy rays toward the cancer site. The treatment ise painless, but side effects frequently results |
internal therapy | very small amount of radioactive material is placed inside the body and left for a short period of time. This type of therapy is carried out in the accute care hospital |
chemotherapy | use of medications to treat disease |
What does the medication from chemotherapy do? | interfere with the duplication and growth of the rapidly multiplying cancer cells. This affects normal cells as well |
What chemotherapy drug affect | bone marrow, gastrointestinal tract, mouth, hair, skin, reproductive system, urinary tract, emotional state |
What are appliative measures used for? | to reduce pain and discomfort in cancer patients. |
Report these side effect at once | fever, sudden weight loss or gain, bleeding or hemorrhage, changes in vital signs, intense or severe pain, changes in behavior, severe constipation or diarrhea |

aqueous humor | fluid in the space between the cornea and lens |
cornea | clea pasticlike covering |
iris | circle of color |
pupil | the opening in the center of the iris through which light enters |
lens | directly behind the pupil, focuses the imagge upon the retina |
retina | back part of the eye; receives image and sends impulses to the optic nerve |
optic nerve | receives impulses from the rods and cones in the retina and transmits them to the brain |
presbyopia | lends loses its ability to focus clearly due to loss of elasticity |
glaucoma | increased pressure within the eye that can lead to blindness due to pressure on the optic nerve |
What are the 3 main parts of the ear? | outer ear, middle ear, and inner ear |
outer ear | leads to the small opening of the middle ear. The outer ear and middle ear is separated by the eardrum |
How do we hear? | Sound waves strike the eardrum (tympanic membrane), causing it to vibrate. The vibration causes the tiny bones to move. Through a complex process, sound stimuli are transmitted to nerves that transport the signal to the brain |
