A Level Biology "Breathing in Humans"
You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/
In this video, we look at breathing in humans. This is also called ventilation. First we explore inhalation, looking at the muscles involved and how inhalation is an active process. We then explore exhalation. We also look at how the internal and external intercostal muscles are antagonistic.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.

Gas Exchange: The Structure of the Lungs in a Snap! Unlock the full A-level Biology course at http://bit.ly/2ZagyJm created by Adam Tildesley, Biology expert at SnapRevise and graduate of Cambridge University.
The key points covered of this video include:
1. Introduction to the Lungs
2. Trachea and Bronchi
3. Bronchioles
4. Alveoli
Introduction to the Lungs
Mammals require a large amount of oxygen and produce a large amount of carbon dioxide. They are large organisms, they have a high metabolic rate and level of activity. To deal with these constraints mammals evolved lungs.
The Trachea and Bronchi
The trachea and bronchi connect the lungs to the mouth. They contain many C-shaped rings of cartilage to provide support and flexibility. This diagram shows...

A Level Biology Revision "Gas Exchange in Mammals"
You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/
In this video, we look at gas exchange in mammals. First we look at the structure of the lungs, focussing on two adaptations of the trachea. We then explore the structure and function of the alveoli, looking at how the alveoli are adapted for the efficient diffusion of oxygen and carbon dioxide.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.

Gas Exchange: The Structure of the Lungs in a Snap! Unlock the full A-level Biology course at http://bit.ly/2ZagyJm created by Adam Tildesley, Biology expert at SnapRevise and graduate of Cambridge University.
The key points covered of this video include:
1. Introduction to the Lungs
2. Trachea and Bronchi
3. Bronchioles
4. Alveoli
Introduction to the Lungs
Mammals require a large amount of oxygen and produce a large amount of carbon dioxide. They are large organisms, they have a high metabolic rate and level of activity. To deal with these constraints mammals evolved lungs.
The Trachea and Bronchi
The trachea and bronchi connect the lungs to the mouth. They contain many C-shaped rings of cartilage to provide support and flexibility. This diagram shows a cross-section of a bronchus as would be seen under a microscope. Smooth muscle allows them to constrict to reduce air flow. The walls are line with ciliated epithelial tissue containing goblet cells. Goblet cells secrete mucus that traps dirt and pathogens. Ciliated epithelium wafts mucus up out of the airways.
Bronchioles
The bronchioles lead from the two bronchi to the alveoli. The bronchi consist mainly of smooth muscle and epithelial cells. Larger ones may have cartilage but most do not.
The Alveoli
The lungs consist mostly of millions of alveoli. Alveoli consist of squamous epithelial tissue and elastic fibres. This is a micrograph of a section of lung tissue showing alveoli. The alveoli show a variety of adaptations that suit them to gas exchange: Large surface area and good blood supply, short diffusion distance for gasses to travel.
Summary
Lungs are highly complex gas exchange organs
The alveoli are gas-filled sacs specialised for gas exchange
The trachea, bronchi and bronchioles deliver gasses to and from the alveoli
The functions on different parts of the lungs are represented in their structures that show their specific adaptations towards carrying out their roles

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/
In this video, we look at gas exchange in mammals. First we look at the structure of the lungs, focussing on two adaptations of the trachea. We then explore the structure and function of the alveoli, looking at how the alveoli are adapted for the efficient diffusion of oxygen and carbon dioxide.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
