30.1 Respiratory and Circulatory Functions The respiratory and circulatory systems bring oxygen and nutrients to the cells.
THE RESPIRATORY SYSTEM provides oxygen to the cells and removes carbon dioxide from the body. works closely with circulatory system. made of following.
The Respiratory System
Oxygen carbon dioxide The respiratory system is the system of the body that deals with breathing. When we breath, the body takes in the oxygen it needs.
 The respiratory system uses many parts for breathing in oxygen and releasing carbon dioxide.  These include the nose, the trachea, and the lungs.
Respiratory System. Function of the Lungs  Supplies oxygen to the blood by inhaling. This oxygen is then carried to all the cells of the body.  Removes.
THE RESPIRATORY SYSTEM Main Function: Exchanges oxygen and carbon dioxide between the blood, air & tissues.

Breathing Process

Main Function Gas exchange - Inhale Oxygen / Exhale Carbon Dioxide Diaphragm = Major muscle of breathing Contracts during inhaling Relaxes during exhaling

Inhaling Oxygen enters trachea & inflates lungs Requires energy Intercostal muscles contract to increase lung capacity; Diaphragm contracts

Exhaling Carbon Dioxide is forced out from the lungs Passive Intercostal muscle relax; Diaphragm relaxes, moves upward & pushes air out Only requires energy when a respiratory disease is present

Chest Tube Hollow, flexible tube that acts as a drain Pt. Conditions Post-op Pneumothorax Fluid in the lung
