A horse must win:1-Kentucky Derby2- Belmont Stakes3- Preakness
17A. Describe the purpose of the respiratory systemWhat do race horses have to do with the respiratory system?18A. Describe the purpose of the respiratory systemFunction of Respiratory System 1. To obtain and use oxygen 2. To eliminate carbon dioxide 19B. List & describe the structures of the respiratory system1. Nostrils Also called nares Paired, external openingsSeparated by nasal septum
20B. List & describe the structures of the respiratory system1. Nostrils contdDilatable a. Species Differences i Horse--Very Pliable and Dilatable ii. Pig--Rigid
212. Nasal Cavities Paired Separated by Nasal Septum, and from mouth by palate
3. Pharynx Common pathway for air and food B. List & describe the structures of the respiratory system224. Larynx "Voice Box" Organ of Phonation (Sound Production) Sound produced by controlled passage of air which causes vibration of vocal chords Syrinx Voice Box for Birds Located where trachea divides from bronchi Vibrating Muscles
B. List & describe the structures of the respiratory system235. Trachea Primary passage way to Lungs Cartilage Rings prevent collapse of airway
6. Bronchi 2 main branches from trachea
B. List & describe the structures of the respiratory system
247. BronchiolesSmaller stems of bronchi
8. AlveoliPrinciple site of gaseous diffusion between air and blood
B. List & describe the structures of the respiratory system
25Lungs Principle Organ of Respiratory System Paired, found in Thorax Thorax = chesta. Thorax expansion causes Lung expansion
B. List & describe the structures of the respiratory system

DiaphragmAlveoli28Respiratory Cycle:1. Inspiration A. Intake of air B. Enlargement of thorax and lungsC. Diaphragm pulls down creating negative air pressure
C. Describe the respiratory cycle, frequency, and factors that effect respiration in animals29Respiratory Cycle:2. Expiration A. Removal of air B. Contains mostly Carbon DioxideC. Diaphragm pushes UP
C. Describe the respiratory cycle, frequency, and factors that effect respiration in animals30Frequency A. Number of Respiratory Cycles per minute B. Factors affecting Respiratory Frequency a. Species variations Horse 12 Cow 29 Pig 40 Sheep 25 b. Body Size --Heavy animals breath heavier
C. Describe the respiratory cycle, frequency, and factors that effect respiration in animals31Frequency Contdc. Age -Younger less d. Exercise -Increases e. Excitement -Increases f. Environmental Temperature -Faster in heat (panting)
C. Describe the respiratory cycle, frequency, and factors that effect respiration in animals32Frequency Contdg. Pregnancy --Increases h. Degree of filling of Intestine --Increases I. State of health --Disease increases

35E. Follow the path of a blood cell through the circulatory system
Circulatory System is a closed circuit pathBlood cells follow this path over, and over, and over again
Circulatory System
36E. Follow the path of a blood cell through the circulatory system
1-Capillary:Thin walled blood vesselsSite of gas exchangeMicroscopic in sizeEvery inch of your body is covered in hundreds of capillaries
Follow the Circulatory System
37E. Follow the path of a blood cell through the circulatory system
2-Vein:Pathway of blood headed BACK to the heartAlways deoxygenated With 1 exception
Follow the Circulatory SystemSmall Veins are called Venules

E. Follow the path of a blood cell through the circulatory system
Follow the Circulatory System13-ArteriesLARGE Blood passageways that take OXYGENATED blood AWAY from the heart
49E. Follow the path of a blood cell through the circulatory system
Follow the Circulatory SystemCapillaries (again)Here is where the process starts all overJunction between arteries and veins

Trivia Question:Which species of animal has a second heart?The frog is an important part of the horse's circulatory system it pumps blood up the horse's leg each time the frog makes contact with the ground. The blood flows down the horse's leg into the digital cushion, a fibrous part of the inner hoof located just above the frog which contains a network of blood vessels. The horse's weight then compresses the frog on the ground, squeezing the blood out of the digital cushion, and pushing it back up the horse's legs.
BellworkTell me everything you know about the horse racing industry54BellworkName 2 purposes of the respiratory systemCompare the structure of the nares of the horse and the pigWhat is the name of the voice box?What is the name of the roosters voice box?List the pathway of an air molecule from the time it enters the nasal passages til it reaches the alveoli.
55Bellwork 11-17-09Sketch a diagram of the lungs. Include the bronchus, bronchioles, alveoli, etc.
56BellworkName the 4 chambers of the heart in the order that blood passes through themWhat valve connects the right atrium and ventricle?What valve connects the left atrium and ventricle?What structure is the site of gas (oxygen) exchange?What is the definition of a vein?What is the definition of an artery?What is the only vein in the body that carries oxygenated blood?BellworkDescribe the path of Robbie the red blood cell as he travels from a capillary, back to the heart and ends up in a capillary again.
