Flashcards in 3.1.3- Tissues In The Gaseous Exchange System Deck (22):
1

Explain what villus ted epithelium is.

A later T cells with many hair like protrusions called cilia.

2

Explain what elastic fibres are.

Protein fibres that can deform and then recoil to their original shape.

3

Explain briefly what goblet cells are.

Mucus secreting cells.

4

explain briefly what smooth muscle is.

Involuntary muscle that contracts without the need for conscious thought.

5

List the five tissues that are found within the gaseous exchange system.

Cartilage
Smooth muscle
Elastic fibres
Ciliated epithelium
Goblet cells

6

What are the two parts of the gaseous exchange system that have all five types of tissue?

The trachea and the bronchi.

7

What is the one type of tissue that is found in all parts of the gaseous exchange system in mammals- the alveoli, trachea, bronchi and bronchioles?

Elastic fibres.

8

How is cartilage found in the trachea compared to in the bronchi?

In the trachea, it is in large, C shaped pieces and in the bronchi it is found in small chunks.

9

What are the different types of tissue found within the trachea?

Cartilage (large C shaped pieces), smooth muscle, elastic fibres, goblet cells and ciliated epithelia.

10

Explain what different types of tissue are found within the bronchi.

Smaller pieces of cartilage, smooth muscle, elastic fibres, goblet sells and ciliated epithelia.

11

Explain what different toes of tissue is found in the larger bronchioles.

Smooth muscle, elastic tissue, goblet cells and ciliated epithelia.

12

What types of tissue are found in the smaller bronchioles?

Smooth muscle, elastic fibres and ciliated epithelium.

13

Explain what types of tissues are found in the smallest bronchioles.

Elastic fibres and NON ciliated epithelia.

14

Explain what type of tissue is found I thin the alveoli.

Elastic fibres and NON ciliated epithelia.

15

Explain the three things that the tracheal, the bronchi and the bronchioles must have in order to be effective air passage systems.

-be large enough to allow sufficient air flow without obstruction
-be flexible to allow movement
-be supported to prevent collapse when the air pressure inside is low during inspiration

16

Explain the function of cartilage within the gaseous exchange system.

It provides support and helps prevent the collapse of the trachea and bronchi during inspiration.

17

Explain the function of cartilage specifically within the trachea.

In he trachea, the cartilage is in C shaped rings that allow for flexibility and space for food to pass down the oesophagus.

18

Explain what the smooth muscle within the trachea, bronchi and larger and smaller bronchioles does.

It controls their diameter. It relaxes during exercise to widen lumen snd create less airflow resistance so air can flow in and out of lungs easier and it contracts for the opposite effect.

19

Explain what the function of the elastic fibres is within the alveoli, bronchi, trachea and bronchioles.

It helps with the breaking process. They stretch during inspiration and recoil to their original shape and size in order to push air out.

20

What is they nation of the ciliated epithelia within the trachea, bronchi, larger and smaller bronchioles?

It beats the music band to prevent mucus build up. It moves music from the alveoli to the throat where the mucus is swallowed. Prevents mucus build up that could lead to infection.

21

What is the function of goblet calls found within the trachea, bronchi and larger bronchioles?

It releases music that traps pathogens to help protect the lungs from infection by these pathogens. They are found between ciliated epithelia Cells.

22

What is cartilage?

A form of connective tissue.
