12 Introduction
13 Introduction Respiration (AKA: breathing) Movement of air into and out of the lungs. Breathing is the most easily observable of the body's vital signs.
14 Introduction The respiratory and cardiovascular systems work together to provide oxygen to the tissues and remove metabolic wastes including carbon dioxide. Failure of either system results in disruption of homeostasis and rapid cell death from oxygen deprivation.
15 Anatomy Upper respiratory tract Lower respiratory tract Diaphragm Sinuses
16 Anatomy Upper respiratory tract: Nose and nasal cavity Pharynx Larynx
17 Anatomy Lower respiratory tract: Trachea Bronchi and bronchioles Alveolar ducts and alveoli Lungs
18 Diaphragm Anatomy
19 Sinuses Anatomy
20 Exchange gases Olfaction Sound production Maintenance of homeostasis Physiology
21 Physiology Exchange gases Oxygen and CO2 exchange occurs through the capillary walls in the lungs and in the systemic circulation.
22 Physiology Olfaction The sense of smell. During inhalation, scent molecules are forced against ends of the olfactory nerves which connect to the olfactory bulb. The nerve impulse is then carried to the cortex for interpretation.
23 Physiology Sound production Air moving over the vocal cords combined with movements of the lips, facial muscles, and tongue forms words and produces speech.
24 Physiology Maintenance of homeostasis Maintains oxygen levels in the blood. Eliminates wastes (carbon dioxide, heat). Regulates blood ph.
25 Upper Respiratory Tract
26 Upper Respiratory Tract B A. Nose B. Nasal cavity C. Oral cavity D. Pharynx E. Epiglottis F. Larynx A C E D F
27 Upper Respiratory Tract Nose Port of entry for air and the beginning of the air conduction pathway. Nasal hair Traps particles and foreign matter as air flows through the nose.
28 Upper Respiratory Tract Nasal cavity Cavity just behind the nose where air is warmed by superficial blood vessels and moistened by mucosal secretions.
29 Upper Respiratory Tract Cilia Tiny hair-like projections of the mucosae that trap foreign particles and transport them down the throat where they are either swallowed or coughed out through the mouth.
30 Upper Respiratory Tract Pharynx (AKA: throat) Muscular tube shared by the respiratory and digestive systems. Contains tonsils and openings to the Eustachian tubes.
31 Upper Respiratory Tract Larynx (AKA: voice box) Connects the pharynx to the trachea. Houses the vocal cords where sound is produced when air passes over them.
32 Upper Respiratory Tract Epiglottis Cartilage in the larynx that closes the trachea during swallowing to prevent food and water from entering the lower respiratory tract.

38 Classroom Rules Punctuality- everybody's time is precious: Be ready to learn by the start of class, we'll have you out of here on time Tardiness: arriving late, late return after breaks, leaving early The following are not allowed: Bare feet Side talking Lying down Inappropriate clothing Food or drink except water Phones in classrooms, clinic or bathrooms You will receive one verbal warning, then you'll have to leave the room.
39 Lower Respiratory Tract
40 Lower Respiratory Tract Trachea (windpipe) Bronchi (primary) Lungs: Secondary bronchi Tertiary bronchi Bronchioles Alveolar ducts Alveoli Diaphragm Bronchi Trachea Alveoli Bronchioles Diaphragm
41 Lower Respiratory Tract Trachea (AKA: windpipe) Tube that connects the larynx to the bronchi.
42 Lower Respiratory Tract Primary bronchi Large air conduction passageways from the trachea to each lung.
43 Lower Respiratory Tract Lungs Primary organs of respiration; extends from the diaphragm to just above the clavicles. Right lungs has 3 lobes. Left lung has 2 lobes.
44 Lower Respiratory Tract Lungs Primary organs of respiration; extends from the diaphragm to just above the clavicles. Right lungs has 3 lobes. Left lung has 2 lobes.
45 Lower Respiratory Tract Secondary and tertiary bronchi (not detailed in Salvo) Branches from the primary bronchi, similar to them but decreasing in size.
46 Lower Respiratory Tract Bronchioles Smaller branches off the tertiary bronchi, having no cartilage, and surrounded by smooth muscle.
47 Lower Respiratory Tract Alveolar ducts Connect bronchioles to alveoli.
48 Lower Respiratory Tract Alveoli Tiny sacs attached in clusters resembling grapes to alveolar ducts. Made of single-layer epithelial tissue and surrounded by capillaries which together make gas exchange possible.
49 Lower Respiratory Tract Diaphragm Main muscle of respiration and structure separating the thoracic cavity from the abdominal cavity. Primary Bronchi Trachea Alveoli Bronchioles Diaphragm
50 Breathing
51 Breathing Breathing Mechanical action consisting of two phases: inhalation (inspiration) and exhalation (expiration). Adults breath times per minute.
52 Breathing Inhalation (AKA: inspiration) Process of drawing air into the lungs. 1. Diaphragm contracts and moves down. 2. External intercostals contract to lift the ribcage up and out. 3. Pressure in the lungs is now lower compared to atmospheric pressure. 4. Air moves from higher pressure (atmosphere) to lower pressure (lungs).
53 External intercostals
54
55 Breathing Forced inhalation Intensified and voluntary inhalation that requires contraction of accessory muscles of inhalation. (sternocleidomastoid, scalenes, and pectoralis minor).
56 Breathing Exhalation (AKA: expiration) Process of expelling air from the lungs. 1. Diaphragm relaxes, elastic recoil of stretched tissues causes it to rise up. 2. Ribcage and lungs are reduced in size as a result. 3. Pressure in the lungs is now higher compared to atmospheric pressure. 4. Air moves from higher pressure (lungs) to lower pressure (atmosphere).
57
58 Breathing Forced exhalation Intensified and voluntary exhalation that requires contraction of accessory muscles of exhalation (internal intercostals and abdominal).
59 Breathing Volitional/voluntary breathing Allows you to hold your breath while swimming under water and to take deep breaths to project your voice during public speaking.
60 External and Internal Respiration
61 External and Internal Respiration External respiration (AKA: pulmonary respiration) Gas exchange in the lungs. Occurs by diffusion between blood in capillaries and air in the alveoli.
62 External and Internal Respiration Internal respiration (AKA: tissue respiration) Gas exchange between blood and the body tissues.
