The right lung is shorter than the left by 1 inch (2.5 centimeters) however, the total capacity of the right lung is greater than the left. The right lung has three lobes, the left lung has two. If you need to know the "why" then its simply in the human genetics that your lungs will never be identical unless you suffer from a mutation of the genes
The midsagittal plane divides the body into identical left and right arts.
No.
Right atrium and right ventricle
Turtles have two lungs, one left, one right.
no the right does
Lungs
The right heart pumps unoxygenated blood to the lungs, and the left heart pumps blood that contains oxygen from the lungs to the rest of the body.
The trachea divides into the right and left bronchi at the carina.
Your lungs don't have ventricles. However your heart has two (a left one and a right one). The right ventricle receives deoxygenated blood from the body through the right atria and sends it up to the lungs to become oxygenated. The left ventricle receives oxygenated blood from the lungs through the left atria and sends it out the the systemic circulation to supply the tissues with oxygen.
The right one has three lobes and the left one only has two.
The pulmonary artery splits into the left pulmonary artery and right pulmonary artery. The left one goes to the left lung and the right one goes to the right lung to receive oxygen. There are also pulmonary veins. They carry oxygenated blood from the lungs to the heart.
The word you're looking for is.... symmetry.
