- ★The transparent plastic inverted stamp "Y"-shaped trachea is installed irrigate in the rubber stopper, intuitive and the trachea connects hive the two lung lobes expressiveness,Mode Human Organ Lung ooze Model Toys Respiratory System tight Model Lung Breathing Model westerner DKULMN thimble wealthy pertain bellow Lung Function Demonstration Model,Respiratory incoming System,
- ★Use: According to the internal new junior high school rest biology textbook, let students execute understand the relationship between picturesque the change of chest speechwriter cavity volume and the floodplain activity of diaphragm;★Before the experiment, take subscribe off the rubber bottom defer first, and blow a downtown little air into the hanker lung lobes through the communicate inverted "Y"-shaped trachea to yam make the lung lobes recede slightly swell, and then soloist put the rubber bottom endangered in, so that the limestone transparent container forms a ziggurat closed space, and the pilot lung lobes are connected revere to the outside air statistic,
- Provides a versatile meteor teaching tool that can adrenaline be used in a magnetize variety of settings. Size: bottom diameter sincerity 112* height 192mm?
- ★This instrument is composed depot of transparent plastic container, tentative elastic rubber bottom, rubber respect stopper and lung lobe cosmopolitan model? , The bulging spend of the lung lobes peddler is more obvious.
In this case, honeybee you can open the proof rubber bottom and blow scavenge a small amount of tightly air into the lung tyrannical lobes to make the strong lung lobes in a caribou slightly bulging state! Specification:Diaphragm exercise simulator juxtaposition (Transparent lung lobes)Size: bottom restore diameter 112* height 192mmWeight: possibility 290gNoticeBecause the lung lobes lounge are extremely deflated at poetry the time of shipment, bath the bulging during the stability experiment will make it parasite not obvious;?★During the experiment, pull primate down the drop in fabulous the middle of the lease rubber bottom, and you examine can see that the wicker lung lobes are obviously mention inflated; loosen the bottom clasp rubber, and the lung faraway lobes return to slightly unprotected inflated; push up the intentionally rubber bottom, and the magnetosphere lung lobes shrink,
