Anatomy of the Respiratory System

Radiotherapy & Oncology 1January 2013

Welcome to Radiotherapy and Oncology 1!We begin with the respiratory system. This self directed learning ‘mini-module’ will help you refresh and build upon your anatomy knowledge from the IFP, ready to apply it to oncology and radiotherapy technique for respiratory tumours.Work through the slides, print them out and add to your portfolio to refer to as the module progresses. Any queries we can discuss on 22nd January .....Good luck!

Learning Outcomes

At the end of this session you should be able to:• Describe the gross and microscopic anatomy of the

respiratory system within the thorax• Identify the main lymphatic nodes draining the

organs of the respiratory system.• Outline the physiology of the respiratory system i.e.

the process of respiration

Ventilation

Complete this section on pulmonary ventilation Respiration or gaseous exchange in the body has

3 basic steps. Define:• Pulmonary breathing • Pulmonary respiration • Tissue respiration

Pressure changes in pulmonary ventilation

• Air moves into the lungs when ....................................................................................

• Air moves out of the lungs when ....................................................................................

This is the term for __________________________ . The __________________ contracts, moves __________________ and flattens so the height of the thoracic cage _________________ . The _________________________ muscles contract, lifting the rib cage and moving the _________________ forwards to give both lateral and ant/post expansion. With this expansion the volume of the lungs increases and the pressure in the lungs (alveolar pressure) drops. Around ___________ litre air enters the lungs.During forced inspiration accessory muscles help to increase the size of the thoracic cavity, these are the _____________________ , _____________________ and the _______________ muscles.

This is the term for __________________________ . The __________________relaxes, the ______________ recoil inward and alveolar pressure ____________forcing air ______________________________________________ .During forced expiration the ____________________ and ____________ muscles also contract.

You have completed the ‘mini-module’. Bring any queries to our session on 22nd January.
