Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons. Learners use the models to investigate how movements of the diaphragm cause lungs to inflate. This activity can be enhanced by sharing the "Health Hazards of Lunar Dust" Podcast with learners (see related resource link). This resource includes background information and variation ideas.

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).

Students explore the inhalation/exhalation process that occurs in the lungs during respiration. Using everyday materials, each student team creates a model pair of lungs.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Cystic fibrosis (CF) is a lung disorder affecting more than 70,000 people worldwide. Genetic mutations leading to defective fluid clearance in the lungs cause progressive airway damage. The most life-threatening challenge in patients with CF is chronic infections, which cause severe airway inflammation. Monitoring these infections could help doctors track patients’ health, informing treatment decisions. Unfortunately, current infection surveillance techniques provide a limited picture of the full spectrum of lung microbes in CF. A new study aimed to more fully define the lower airway bacterial microbiota in patients with CF. Using high-throughput sequencing, researchers evaluated sputum samples from 299 patients from Europe and the U.S. The results showed that microbiota diversity decreased when lung function declined..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

The lungs are the site for gaseous exchange, and are situated within the thoracic cavity. They occupy approximately 5% of the body volume in mammals when relaxed, and their elastic nature allows them to expand and contract with the processes of inspiration and expiration.

Every time you take a breath, oxygen makes it way into your lungs. Follow along on that journey! Rishi is a pediatric infectious disease physician and works at Khan Academy. Created by Rishi Desai.

Blood circles through the heart, which pumps it to the lungs where it picks up oxygen - this is the pulmonary circulation. This resources tracks the route of blood through the heart and lungs and provides illustrated diagrams and assessment tools.

The pulmonary system including the lungs, larynx, trachea, bronchi, bronchioles, alveoli and thoracic diaphragm.
