Respiratory System

Agriculture, Food, and, Natural Resource Standards Addressed AS. 01. Evaluate the development and implications of animal origin, domestication and distribution on production practices and the environment. AS. 01. 02. a. Research and summarize major components of animal systems.

Upper Respiratory System Consists of the: nose (snout, nostrils, etc. ) mouth pharynx epiglottis larynx

Upper Respiratory System Nasal cavity Pharynx Esophagus Larynx Mouth Epiglottis Tongue Trachea

Upper Respiratory System Mucous membranes lining of respiratory tract that secrete mucus.

Upper Respiratory System Mucus slimy secretion that helps to warm, moisten, and filter air.

Upper Respiratory System Cilia tiny wave-like hairs that line the nostrils and help to filter air.

Upper Respiratory System Pharynx passageway shared by the digestive and respiratory systems.

Upper Respiratory System Pharynx

Upper Respiratory System Epiglottis tiny flap that covers the larynx during swallowing.

Upper Respiratory System Epiglottis

Upper Respiratory System Larynx “voice box” contains vocal cords that vibrate when air passes

Upper Respiratory System Larynx

Lower Respiratory System Trachea “windpipe” has rings of cartilage that keep its shape.

Trachea

Lower Respiratory System Bronchi branches at the bottom of the trachea that are contained in the lungs.

Bronchi

Lower Respiratory System Bronchial tree term describing how branches of the bronchi get continually smaller, like a tree branch.

Lower Respiratory System Bronchioles smallest branches of the bronchial tree.

Bronchioles

Lower Respiratory System Alveoli grape-like clusters at ends of bronchioles where exchange of gases occurs.

Alveoli

Lower Respiratory System Lungs paired organs containing bronchi that are divided into clearly defined lobes.

Lungs

Lower Respiratory System Diaphragm a muscle located below the lungs that contracts causing the lungs to fill with air.

Breathing Inhalation - drawing in of a breath

Breathing Exhalation – release of a breath

Breathing Apnea – not breathing

Breathing Dyspnea – difficult breathing

Breathing Bradypnea – abnormally slow breathing rate

Breathing Tachypnea – abnormally fast breathing rate

Breathing Respiration – exchange of oxygen and carbon dioxide gases in the lungs
