| Question | Answer |
|---|---|
| integumentary system(skin,hair,fingernails,toenails,sweat glands,and oil glands) | protects the body,helps regulate body temperature,eliminate some waste,detects sensations such as touch ,pain,warmth and cold. |
| skeletal system(bones joints cartilage) | supports and protects the body,provides surface area for muscle attachments,aids in body movement,houses cells that produce blood cells,stores minerals and lipids |
| muscular system(skeletal muscle tissue) | participates in body movements such as walking,maintaining posture,produces heat. |
| nervous system(brain, spinal cord,nerves,eyes,ears) | detects changes in the bodys internal and external enviorments,interprets changes and responds by causing muscular contractions or glandular secretions |
| endocrine system(pineal gland,hypothalmas,pituitaty gland,thymus gland,parathyroid glands,adrenal glands,pancreas,ovaries,testes) | regulates body activities by releasing hormones |
| cardiovascular system (blood, heart,blood vessels) | heart pumps blood through blood vessels,blood carries oxygen and nutrients to cells and carbon dioxide and wastes away from cells |
| lymphatic system(immunity)(lymphatic fluid and vessels,spleen,thymus,lymph nodes,tonsils | returns proteins and fluid to blood,carries lipids from gastrointestinal tract to blood. |
| respiratory system(lungs,pharynx{throat},larnx{voice box},trachea{windpipe},bronchial tubes.) | transfers oxygen from inhaled air to blood and carbon dioxide from blood to exhaled air,helps regulate acid base balance of body fluids. |
| digestive system(mouth,pharynx,esophagus,stomach,small intestines,large intestines,anus,salvary glands,liver,gallbladder,pancreas.) | acheives physical and chemical breakdown of food,absorbs nutrients,eliminates solid wastes. |
| urinary system(kidneys,ureters,urinary bladder,urethrea) | eliminates wastes and regulatesvolumes and chemical composition of blood,helps maintain the acid base balance of body fluids,helps regulate the production of red blood cells |
| reproductive system(testes,ovaries,uterus,vagina,mammary glands,ductus,deferens,seminal vesicals,prostate and penis) | gonads produce gametes that unite to form new organism,gonads also release homormones that regulate reproduction and other body processes. |
