Anatomy of the Respiratory System ● the nose ● the nasal cavity ● the pharynx ● the larynx ● the trachea ● the bronchi ● the lungs

Anatomy of the Respiratory System

● the nose ● nares ● the nasal cavity ● conchae ● the palate ● the sinuses

Anatomy of the Respiratory System ● the pharynx ● tonsils ● the larynx ● epiglottis ● the trachea ● C rings

Lung Dissection ● Video Video

Review ● Take out a piece of paper and answer these questions ● 1.How is breathing related to cellular respiration? ● 2. How did exercise affect the rate of cellular respiration? ● How can bromothymol blue pH help you measure the rate of cellular respiration?

A closer look at the mechanics ● video video

Respiration investigation ● In this activity you will measure and monitor breathing rates to better understand respiration, inspiration, and lung capacity ● Grab a worksheet from the front: 1 per table ● Use cellphone as timer ● Work with people from your table ● Answer questions on worksheet and put everyone's name onit

Lesson 2 Respiration: Mechanics and Control Chapter 9: The Respiratory System

● respiration ● nonrespiratory air maneuvers ● control of breathing ● lung volume Respiration: Mechanics and Control

● also known as breathing ● air always moves from a higher pressure area to a lower pressure area ● four key tasks involved in respiration ● pulmonary ventilation ● external respiration ● respiratory gas transport ● internal respiration Respiration

● Boyle’s law ● as the volume of a gas increases, the pressure of the gas decreases Respiration

● inspiration (inhalation) ● diaphragm and intercostal muscles contract ● thoracic cavity expands ● expiration (exhalation) ● diaphragm and intercostal muscles relax ● thoracic cavity shrinks Respiration

Nonrespiratory Air Maneuvers

● neural factors ● pons and medulla oblongata ● chemical factors ● central chemoreceptors ● peripheral chemoreceptors ● mechanoreceptors Control of Breathing

● static ● air volume in lungs ● dynamic ● air volume in lungs based on time Lung Volume

● tidal volume ● vital capacity ● residual volume ● functional residual capacity ● inspiratory reserve volume ● expiratory reserve volume ● total lung capacity Static Lung Volume

● forced expiratory volume in one second ● forced expiratory volume in one second/forced vital capacity Dynamic Lung Volume

True or False? 1. The pons and medulla control breathing. 2. Static lung volume involves time. 3. Muscles contract in inspiration. 4. Larger gas volume, higher pressure. 5. Gas moves from low to high pressure. Review and Assessment

Plan ● Quiz ● read about respiratory organ ● write a paragraph about organ (everyone must turn in) ● discuss important points with table ● write down what to say and turn in a copy ● 7.3 notes ● 7.3 key terms and study questions

Review ● Video Video ● Three things that I know about the respiratory system ● Two things I still don’t understand ● One thing that would really help me to prepare for the test

Overall function ● Functions of the respiratory system ● - gas exchange ● - filter and remove foreign particles from inspired air ● - humidify and control the temperature of the inspired air ● - produce sound (voice) ● - provide sense of smell ● - aid in immune defense ● - conduct air to the lower respiratory tract

Major respiratory organs ● Nose ● Pharynx ● Larynx ● Trachea ● Bronchi and Alveoli ● Lungs ● Thorax

Lungs 3B ● Cone shaped organs ● Elastic sacs with branching passages ● Oxygen into the blood ● Carbon dioxide is removed ● Lungs are in vertebrates, except fish ● The lobes can be divided into more functional lobes called bronchopulmonary segments ● 3 sections in the right lung, 2 in the left ● 2 spongy air filled organs ● Contains bronchi and alveoli ● Right lung has superior, middle, and inferior ● The right lung is more indented then the left
