Hi dude I might be wrong but i'm 100% thinking it is A)Truck 1 carries oxygen and Truck 2 carries carbon dioxide. The reason I say this is because the heart and lungs have two main systems known as respiratory system and circulatory system that take carbon dioxide and replaces it with oxygen, which it takes to the brain so you body can function. Hope this helps sorry it so lately answered.

What tissues are in the respiratory system?
seropon [69]

Answer:

Simple squamous epithelium,stratified squamous epithelium,pseudostratified columnar epithelium

Explanation:

The respiratory system is made up of many different types of tissues and they differ according to their locations in the respiratory system.

1.Simple squamous epithelium: It is found within the alveoles of the lungs. These cells are single layer,flat (squamous) cells. It controls the permeability of blood vessels in the lungs. When you inhale it allows more oxygen to be absorbed in the  blood flows.

2.stratified squamous epithelium: It is found at mouth surface primarily tongue and throat . These cells are stratified that is they are many layered because everyday whatever we put in our  mouth and throat it protects from wear and tear. It gives physical protection from pathogens as well.

3.pseudostratified columnar epithelium: It is a lining of the nasal cavity trachea and bronchi. This layer is ciliary to trap patheogen on entering into the lungs.
