Lesson aims Review lecture 1 Review lecture 1 · (part 1) (part 1) Henry's Law · Respiratory responses & adaptations · Move onto the cardiovascular system · Lecture 1 recall task 1) Identify the route that air takes from the atmosphere to the blood (e.g., air enters through the mouth and then...). 2) Explain the mechanism of how air is drawn into the body with reference to Boyle's law and diffusion. 3) With reference to Dalton's law explain why training at altitude can be problematic for athletes. Henry's Law · When a mixture of gases is in contact with a liquid, each gas will dissolve in the liquid in proportion to its partial pressure. · Greater concentration of gas, the more and faster that gas will go into solution in the liquid. · How much gas dissolves in liquid depends on: solubility of the gas in the liquid temperature of the liquid.

peensoolde (12 sõrmik) Näiteks koertel säilivad mõlemad nii ventraalne kui dorsaalne pankreasejuha. 80. Kuidas arenevad kopsud? Endodermist tekib hingetoru ja neelu epiteel, bronhid ja alveoolid Splanhiline mesoderm (külgplaadi mesoderm) annab aluse sidekoele, kõhredele, kopsu silelihastele Hingamiselundkond areneb eessoolest vastusena ümbritsevast mesodermist tulevatele FGF ja WNT signaalile Respiratoorsest endodermist moodustub neelu piirkonnas kopsupung, mis pikeneb ja sirgest osast (neelu piirkonnas) areneb hingetoru sisevooderdus ja tagumisest osast paarilised harunevad bronhipungad (annavad aluse primaarsetele bronhidele) Seejärel tekivad sekundaarsed bronhipungad (neist arenevad sekundaarsed bronhid) ja need omakorda harunevad mitmeid kordi (moodustuvad bronhioolid, alveoolid) * harunemist aitavad kontrollida
