Did you know the difference between resistors and rheostat ?

Resistors and rheostat both are used in a circuit for the same function, to offer resistance to the current flow. The only difference is that in resistors, the resistance value is fixed (like 100 ohm, 200 ohm) and in rheostat the resistance value can varied within a range as per requirement (like 1–200 ohm).

Respiratory system
What is the respiratory system?

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

ما هو الجهاز التنفسي؟

الجهاز التنفسي هو شبكة من الأعضاء والأنسجة التي تساعدك على التنفس. يشمل الشعب الهوائية والرئتين والأوعية الدموية. العضلات التي تمد رئتيك بالطاقة هي أيضًا جزء من الجهاز التنفسي. تعمل هذه الأجزاء معًا لتحريك الأكسجين في جميع أنحاء الجسم وتنظيف الغازات العادمة مثل ثاني أكسيد الكربون.
