* Cont Recognition(identify) : Alveoli 2-Types of cells :- Alveolar macrophages- Pneumocytes :
-Terminal bronchioles with clara cells -Divide to regenerate the bronchiolar epith
Type II Pneumocytes(cuboidal) 1- secretion of surfactant.2- divide to regenerate both type I & type II pneumocytes..
Type I Pneumocytes(Simple squamous ) 1- exchange gases.

منخفضة جدا كلها والقيم النسبة
Q3: THE SAME WAY =80%جدا طبيعية فعال النتيجة كويس ركزوا هنا
جدا منخفضة المعطاة القيم ولكن restrictive lung disease

واجب االحتياط ولكن ماهيجي عاالغلب
Plateau
FVC = 5 المنحنى عندها يكون التي القيمة Plateau هي
FEV1 = 4عند خرج الذي الهواء حجم هي
األولى الثانية
FEV1% = (FEV1/FVC) * 100= (4/5) *100=80 %
FEV1% = (FEV1/FVC) * 100
Normal
FEV1% = (FEV1/FVC) * 100
FVC = 2
FEV1 = 1.8
FEV1% = (FEV1/FVC) * 100= (1.8/2) *100=90 %
Restrictive
Plateau
1.8
؟ عرفنا مو كيف أصال ال النقليل مره FVC = 2 ! طبيعي
FEV1% = (FEV1/FVC) * 100
FVC = 3.5
FEV1 = 1.9
FEV1% = (FEV1/FVC) * 100= (1.9/3.5) *100=54 %
obstructive
3.5
Plateau
