The trachea is lined with

A

Ciliated columnar epithelium and mucus secreting goblet cells.

43
Q

true or false? The right brochus is wider, shorter and more verticle than the left.

44
Q

A

true

45

51
Q

In the bronchioles the cartilidge is replaced by…

A

smooth muscle

52
Q

In the bronchioles the ciliated epithelium is replaced by…

non-ciliated columnar epithelium and goblet cells disappear.

53
Q

58
Q

What is external respiration?

A

O2 from atmosphere into lungs to blood. CO2 goes from blood to lungs then to atmosphere.

59
Q

What is internal respiration?

A

Oxygen from blood goes into tissues and waste products go from tissue to blood.

60
Q

Boyles law

A

The pressure of a gas in a closed container is inversely proportional to the volume of a container.

Diffusion allows the movement of substance such as O2 and CO2 across a semipermeable membrane from a region of…

A

high concentration to lower concentration.
