In order to live, grow, and reproduce, all living things need energy obtained from oxygen. From the simplest of cells to the largest of animals, energy is generated from oxygen in a process called respiration, or breathing. Learn about the definition and characteristics of aerobic respiration, the respiratory organs, the process of photosynthesis in plants, different organisms and their respiratory processes, human respiration, lungs and other organs...

Shows readers how our respiratory system works.

Explains the chemical and metabolic processes by which plants transform sunlight into energy, describing concepts central to the fields of thermodynamics and bioenergetics.

This program examines how oxygen and carbon dioxide are transported throughout the body, guided by the brain as it reacts to internal and external stimuli. The process of breathing is modeled by a swimmer, the control of breathing by the brain is analyzed, and oxygen intake by the lungs and transport by red blood cells are discussed. The complementary actions of the circulatory and respiratory systems to meet the body's energy needs are identified,...

This edition of Science Screen Report explores the synergy of two different physiological systems: the respiratory system, for acquiring and processing oxygen, and the circulatory system, for the internal transportation of oxygen and nutrients. Emphasizing the vital roles of the heart, the lungs, capillary action, and Earth's oxygen-rich atmosphere, Energy for Life illustrates clear connections between concepts in anatomy and chemistry.

Explains why we breathe, what happens inside the lungs and heart, and the role of oxygen in our bodies.

This book explores the different parts of our lungs and the unique function each part performs.

An illustrated ABCs book paired with mindfulness and breathing exercises--from A for Astronaut Breath to Z for Zipper Breath.
