Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs, by several cavities, tubes, and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies.
we now address the roles of the respiratory and urinary systems in the homeostatic control of blood gases, pH, blood pressure, and other variables related to the body fluids. This chapter deals with the respiratory system and chapter 23 with the urinary system. Anatomy of the Respiratory System Objectives
Respiratory System Consists of an upper respiratory tract (nose to larynx) and a lower respiratory tract ( trachea onwards) . Conducting portion transports air. - includes the nose, nasal cavity, pharynx, larynx, trachea, and progressively smaller airways, from the primary bronchi to the terminal bronchioles Respiratory portion carries out
The respiratory system consists of structures involved in moving air into and out of the lungs (bulk flow) and in gas exchange (diffusion). LUNGS AND CHEST WALL act as a unit. Each lung is surrounded by a membranous sac (pleura) filled with a thin film of fluid (Fig. 1). This intrapleural fluid serves as a lubricant so the
Anatomy Lecture Notes Section 5: The Respiratory System Arguably, the chief function of the respiratory system is to supply the lungs with oxygen (O 2) and to eliminate carbon dioxide (CO 2) from the body that is constantly being generated by the tissues. The

ANATOMY OF RESPIRATON: - It comprises respiratory tract and respiratory organs. RESPIRATORY TRACT It consists of pair of external nostrils, nasal cavity, internal nares, nasopharynx (throat), larynx (voice box), trachea (wind pipe), bronchi, bronchioles, alveolar duct and alveolar sac.

Anatomy and physiology of the Respiratory system Upper respiratory tract Nose: Humidifies, warms, and filters inspired air. Sinus: Air-filled cavities within the hollow bones that surround the nasal passages & provide resonance during speech. Pharynx: Passageway for the respiratory and digestive tract located behind the oral
cavity is the respiratory portion. The respiratory area is lined with a moist mucous membrane with fine hairlike projections known as cilia, which serve to collect debris. Mucus from cells in the membrane wall also helps to trap particles of dust, carbon, soot, and bacteria.
