The Respiratory System STRUCTURAL PLAN Basic plan of respiratory system would be similar to an inverted tree if it were hollow; leaves of the tree would be comparable to alveoli‚ with the microscopic sacs enclosed by networks of capillaries (Figure 14-1) Passive transport process of diffusion is responsible for the exchange of gases that occur during respiration. RESPIRATORY TRACTS Upper respiratory tract—nose‚ pharynx‚ and larynx Lower respiratory tract—trachea‚ bronchial tree‚ and lungs

Before beginning this Effective Stress Management course‚ I never gave much thought to how well my stressors were controlled. Now that we are at the end of the course‚ I have learned so many new things‚ from the kinds of stress to coping skills and even relaxation techniques. All of this newly found knowledge has helped me to compile the following plan that will help me deal with my stress in the most optimal way. A major stressor in my life is school. I find that this particular stressor triggers

Energy Energy can be found in many forms. These forms can be- Chemical- usually found in substances Heat- this slows down energy and you may become dehydrated Sound- Your body absorbs this‚ and if you feel the energy from upbeat music Electrical – Your body absorbs this Light- Direct sunlight gives your body energy. A chemical bond that is made happens between two atoms or molecules. The energy can only be seen when the atoms or molecules have created a chemical reaction

not required and restores oxygen levels in the atmosphere of the alveolus. This also helps maximise the concentration gradient between the alveolar air and the blood entering and exiting through the capillaries. Pulmonary ventilation is the act of breathing comprised of two phases; inhalation and exhalation. In inhalation‚ air from the environment is drawn into the lungs and in exhalation internal air is drawn out of the lungs. The main mechanisms responsible for pulmonary ventilation are atmospheric

keeps static surroundings in which cells‚ tissues‚ and systems can operate. If there’s an alteration happen‚ these procedures can stop‚ decompress or quicken. Homeostatic mechanism controls a lot of activities inside the body such as our heart rate‚ breathing rate‚ body temperature and‚ blood glucose. “Negative feedback works rather like the central heating system of a building. If the temperature falls below the desired temperature‚ the thermostat will detect this change and send a message to the

Name: Judine Douglas ID#: 3111-0427 Respiratory System The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. What makes up the Respiratory System? The human respiratory system consists of the nose
