Basic biology here. Right lung is divided into 3 lobes, left lung into 2.
Lung sizes do differ, but only marginally. This is true of all mammals. Even in the human, the right lung has three lobes and the left has two.
The right lung is slighty broader and larger in size and in left lung a cardiac notch is present which is for the presence of Heart. So the left lung is divided into two lobes - superior and inferior lobes while the right lung is divided into three loes - superior, middle and inferior. Right lung is also little havier with weight of 625 gm. and of left lung is 567 gm in adult (an average).
The right lung is divided into three lobes (superior, middle and inferior), while the left lung is divided into two lobes (superior and inferior) allowing room for the heart.
A part of his left lung
They are on the left and right side of the heart, and the ribcage protects them. The left lung is a little smaller than the right lung because it shares space in the left side of the chest with the heart. Each lung is divided into sections (lobes).
The oxygen enters your mouth or nose then to your trachea which is a tube that leads the oxygen to your left & right bronchi. From the bronchies, the oxygen goes to the left/ right lung (corresponding to which lung is connected to which bronchi; left bronchi->left lung and right bronchi->right lung) then the lung travels the oxygen to other parts of the body!
your left lung is slightly smaller then your right lung. So your right lung is a little bigger then your left lung.
3 on the right and 2 on the left.
The left lung is on the left and the right lung is on the right.
