7 0

Answer:

Lungs supply oxygen carried by blood to cells of the body. The cells which are responsible for the transportation of oxygen is hemoglobin.

Again this hemoglobin goes to the lungs and dispose carbondioxide there and repeat the process again.

The two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.

Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface.
