This 21-minute video lesson looks at the pulmonary system including the lungs, larynx, trachea, bronchi, bronchioles, alveoli and thoracic diaphragm. [Biology playlist: Lesson 37 of 71].
This course focuses on the complete health assessment, the nursing process, and its relationship to the prevention and early detection of disease in clients across the life span. This course introduces processes of health assessment: interviewing, history-taking, and physical assessment. Dominant models, theories and perspectives are used to explain health behavior are considered in relation to evidence-based health promotion and health education strategies. Students are also expected to identify and apply pathophysiological principles to selected health issues across the lifespan. This course includes a laboratory component complemented by self-directed computer assisted instruction. Incorporated throughout the course is the importance of communication and collaboration across culturally diverse urban populations.
This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).
A study in the art and science of medical diagnosis.
Students explore the inhalation/exhalation process that occurs in the lungs during respiration. Using everyday materials, they create a model pair of lungs.
This patient education program discusses lung cancer and the treatment options. It also reviews the anatomy of the respiratory system, cancer and its causes, symptoms, and diagnosis of the disease. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.
Dolphins are mammals because they have lungs. Even though they live in the water, they must come to the surface to breathe air. They are one of the few mammals that don't have fur.
This site provides information about heart, lung, and blood diseases and sleep disorders. Learn how the heart works. Find out about aneurysms, angioplasty, electrocardiograms, heart attacks, high blood pressure, asthma, cystic fibrosis, sickle cell anemia, insomnia, narcolepsy, and more.
This lesson goes over the parts of the human respiratory system and the gas exchange process that occurs in the lungs. It also covers changes in the respiratory system that occur during spaceflight, such as decreased lung capacity.
There are three lessons in this group. The first two provide students with the opportunity to learn about the circulatory system and conduct an experiment where they take their pulses after different types of activity. During the third lesson, a pediatrician explains how she checks a patient's heart and the ways that a healthy lifestyle (food and exercise) can keep students' hearts healthy.
