Discover how the body breathes and keeps every tissue alive. A clear, practical guide to the mechanics of respiration and the heart’s role in circulation.

The book traces the journey of air and blood through the body, from simple forms of exchange in humble organisms to the twofold process in higher animals: internal gas exchange with tissues and external gas exchange in the lungs. It explains the structure of the lungs, the blood vessels that nourish them, and how breathing movements relate to the chest’s size and the heart’s activity. Readable explanations connect anatomy to real bodily function, helping readers see how respiration and circulation fit together.

How air moves into and out of the lungs, and how these movements relate to breathing sounds and chest mechanics.
The two sets of lung blood vessels and how oxygenated blood is readied to nourish the body.
Different patterns of arterial contraction and relaxation and what they mean for blood pressure.
How respiration occurs in simple organisms as a foundation for understanding human physiology.

Ideal for general readers and students seeking a solid, accessible overview of respiration, circulation, and their nervous system connections.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free.
