CELLLS
| Question | Answer |
|---|---|
| Anatomy | structure of human body |
| Physiology | study of processes, how and why they work, function |
| Pathophysiology | study of how diseases occur and body's response. |
| Cells | basic unit of all living things microscopic vary in shape and size perform different functions carry on all functions of life ( take in food, oxygen, produce heat & energy) |
| Cell membrane | outer protective covering semi permeable- selective in allowing substances in and out of cell |
| Cytoplasm | surrounds nucleus gel like fluid inside cell contains water, salts, protien site of all chemical reactions in cell (Organelle- structures that help cell function) |
| Nucleus | mass in cytoplasm "brain" of cell controls cell activity important in cell division |
| Nucleolus | "protien factory" inside nucleus important in cell reproduction has ribosomes (RNA and Protien), reproduction |
| chromatin | inside nucleus contains DNA and protien condenses to form chromosomes human cell has 46 chromosomes and 23 pairs(genes) |
| centrosomes | inside cytoplasm, near nucleus contain 2 centrioles (seperate in cell division and form fibers that attach to chromosomes) |
| mitochondria | "Furnace" or "Powerhouse" rod shaped organelles located throughout cytoplasm |
| Golgi Apparatus | stack of membrane layers in cytoplasm produces, stores, packages, secretions for discharge from cell |
| Endoplasmic Reticulum | fine network of tubular structures in the cytoplasm transports materials in and out of nucleus aids in synthesis and storage of protien |
| lysosome | contain enzymes that digest and destroy old cells and bacteria important to immune system |
| pinocytic vesicle | pocket like folds in cell membrane allow molecules to enter cell |
| Mitosis | asexual cell reproduction used by most cells |
| Meiosis | process by which sex cells reproduce |
| tissues | water and dissolved subs. joined together for common purpose |
| edema | swelling |
| dehydration | inadequate amt. of fluid in tissues |
| Epithetial tissue | covers surface of body skin forms lining of intestines, respiratory, circulatory and urinary form glands in body that reproduce |
| connective tissue | supports organs and other body parts |
| soft connective | Adipose= fatty tissue insulates, padding and energy Fibrous= ligaments/tendons- hold body structures together |
| Hard connective | Cartilage- tough elastic material, btwn bones and at ends of long bones (shock absorber, flexible) found in nose, ears, and larynx (gives shape/form) bone-osseous tissue , forms rigid body structure |
| liquid connective | vascular tissue Blood and lymph circulates O2 and CO2 also transports tissue fluid to circulatory sys. |
| Nerve Tissue | made of neurons controls and coordinates bodys actions by transmitting messages through body Nerves- brain, spinal cord= made of nerve tissue |
| muscle tissue | produces power and movement |
| 3 types of muscle | Skeletal= attached to bone (movement) Cardiac= heart (causes heart to beat) visceral= (smooth) found in walls of respiratory tract, digestive tract, blood vessels and urinary tract |
| organs | 2 or more tissues joined together for a specific purpose |
| system | organs and other body parts joioned together for a particular function * systems work together to form the human bodyyy |
| NERVE | control and communicate |
| EPITHELIUM | secrete and protect |
| MUSCLE | move and protect |
| CONNECTIVE | support and connnect |
