Each lung is fed oxygen by a separate bronchus. select the best answer from the choices provided. t f

The given statement is true.

At lungs level, trachea segmented into two primary bronchi: left primary bronchus which enters the left lung and right primary bronchus which enters the right lung.

In each lung, primary bronchi (both left and right) segmented into tertiary bronchi via secondary bronchi.

Tertiary bronchi divide to form smaller airways termed as bronchioles.

These bronchioles eventually connect with alveoli, specialized sac-like structures which form the site for gas exchange.

Thus, we can conclude that each lung is fed oxygen by a separate bronchus.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
