| Question | Answer |
|---|---|
| 4 characteristics of water | temperature regulator, solvent, chemically inactive, protects parts of the body |
| functions of respiratory system | keeps blood supplied with oxygen, removes carbon dioxide |
| functions of the lymphatic system | immune cells, returns leaked fluid back to the blood, purifies lymphatic fluid, houses cells to attack against foreign substances |
| functions of the muscular system | movement, posture, heat, facial expression |
| functions of the endocrine system | glands secrete hormones to regulate growth, metabolism, and reproduction |
| functions of the digestive system | break down food and elimination of waste |
| functions of the urinary system | eliminate waste, regulates water, electrolytes, and acid-base balance |
| functions of the reproductive system | growth and development of sex organs, reproduction |
| functions of the integumentary system | protection, vit D synthesis |
| functions of the nervous system | sensory input, interpretation, motor output |
| metabolism | the sum total of all chemical and physical processes which go on inside the body to sustain life |
| homeostasis | a steady stage of balance that the body maintains through positive and negative feed back loops |
| 3 major chemical bonds in the body | hydrogen, ionic, covalent |
| function of the cell membrane | ion (protein) gates, transport channels, enzyme activity, receptor sites, enzyme activities, cellular positive and negative balance, cellular water balance, maintain cellular homeostasis |
| mitochondria | organelle that is abundant in ATP |
| cell nucleus | controls most cell activities |
| nucleolus | produces ribosomes |
| cytoskeleton | supports the structure of the cell |
| ribosomes | synthesizes (makes) proteins |
| lysosomes | breaks down large molecules |
| vacuoles | stores food, water, salt, protein, and waste |
| During the process of meiosis each daughter cell has: | 1/2 the number of chromosomes as the parent cell |
| sodium potassium pump | requires energy exchanges 3 sodium and 2 potassium |
| diffusion | no energy required higher to greater concentration |
| osmosis | diffusion of water molecules |
| filtration | passive forces particles out to balance concentration gradient |
| what is the typical balance of pH in the human blood | 7.2 - 7.4 |
| which is more of a threat to human homeostasis: alkaline or acid? | alkaline |
| function of epithelial tissue | repair and reproduction |
| function of the nervous tissue | detect and respond to motor and sensory stimulus |
| function of the muscular tissue | ,movement of bones, joints, and heat production |
| function of the connective tissue | support, bind, protect organs, muscles, and other structures |
| cell | two or more organelles with similar function |
| tissue | two or more cells with similar function |
| organ | two or more tissue with similar funtion |
| anatomical systems | two or more organs with similar function |
| organism | two or more anatomical systems functioning to create an organism |
| mitosis has how many stages of cell division | 4 |
| meiosis has how many stages of cell division | 8 |
| what is the purpose of mitosis | cellular growth and development of the body |
| what is the purpose of meiosis | genetic diversity by producing eggs and sperm |
| what is the best class ever?! | human physiology! |
| what will we be studying next? | Integumentary System |
