مساء الخير والاحساسـ



امممم اسفه تاخرت بكتابه الموضوع

بسسس اعذروني

للحين ما خلصت الجيناتيكس

البدايه راح تكون مع جهاز الهضم

Digestive System

The digestive system uses mechanical and chemical methods to break food

<< لاحضوا زين وفرقوا بين الكيميائي والميكانيكي

Digesting in mouth
Mechanical and chemical digestion start in mouth.

Polysaccharide break down begins in mouth


من اسئله السنوات اللي راحت في البايو

1-
Digestion of ingested starch begins in the:
a. duodenum.
b. jejunum.
c. stomach.
d. mouth.

مثل ما قلنا بالبدايه بالفم

T F Chemical digestion of protein starts in the mouth.

<<الميكانيكل والكميكل يبتدي بالفم
بسسس تاكدوا اذا بروتين يبتدي بالفم !
البروتين في المعده يتحول لببتيد
<< شاغل بالي هالسؤال



-----


Most chemical digestion occurs in the:
a. colon.
b. oesophagus.
c. stomach.
d. small intestine.

<<<اتوقع في الاستوميك

T F Bile secretion includes many enzymes.

<< اتوقع خطا بسس
تاكدوا من الجواب

:t1:

[إيلاف]

T F Chemical digestion of protein starts in the mouth
^
^
أتوقع F
لأن البروتين يبتدي هضمه في المعده .. بسبب وجود الـ pepsin ..
..

Most chemical digestion occurs in the:
a. colon.
b. oesophagus.
c. stomach.
d. small intestine
^
^
من أجزاء الـ small intestine ..
jejunum >> in which most nutrient are digested and absorbed
امم
انا فكرت في الستومك أول .. بس هالجملة استوقفتني ..!!
..
T F Bile secretion includes many enzymes

امم اتوقع انا بعد F

..

الهوجاس ..
شي حلو انك نزلتي الأسئلة .. اتوقع راح تكون مفيييدة كثير ..
يعني راح تكون مثل المراجعه السريعه لأهم الأشياء ..
الله يعطيك العافية ..
ومن القلب .. الله يوفقك ويحقق لك اللي تتمنيه ..
