2 Receptors skeletal muscles need more blood Control Center medulla oblongata Effectors parasympathetic fibers decrease impulses to SA node Stimulus strenuous exercise stop exercising Stimulus High Normal Low Response heart rate increases heart rate decreases Response skeletal muscles need less blood Receptors Medulla Oblongata Control Center Parasypmathetic fibers increae impulses to SA Node Effectors Negative Feedback Mechanism 2

3 10/21/13 Ch 16: Respiratory System 48 Objective: Students will be able to describe the function of the respiratory system overall and the function of each organ of the system. Respiratory System Functions Obtain oxygen for cellular respiration Remove carbon dioxide Filter and entrap particles from air Control the temperature of the air Control water content of the air Produce vocal sounds Participate in smell Help regulate ph of blood Respiration consists of 4 steps: ventilation (mvmnt of air in/out of lungs) external respiration (gas exchange b/w blood and air in lungs) gas transport in blood b/w blood and body cells internal respiration (gas exchange b/w blood and cells) Cellular Respiration Process of oxygen utilization and carbon dioxide production at the cellular level. Produces ATP and occurs primarily in the mitochondria. Functions of Respiratory System 3

4 Functions of Respiratory System 4

5 10/21/13 Ch 16: Respiratory System 50 Objective: Students will be able to describe how respiration is controlled and the effect of disease on respiration. Medulla Ventral Rhythm Respiratory Centers Dorsal innervates the diaphragm and processes sensory information regarding respiratory system Pons pontine respiratory group limits inspiration thereby changing the rhythm of breathing Respiratory centers in brain 5

6 Receptors chemoreceptors in ventral medulla oblongata Control Center respiratory areas in medulla and pons Effectors diaphragm breathing rate increases Stimulus csf levels of H + and CO 2 High Normal Low Response csf levels of H + and CO 2 fall Stimulus Response Receptors Effectors Control Center Negative feedback 6
