Understand how the circulatory system keeps every cell nourished and clean
Discover the core ideas behind how blood moves through a closed network, delivering energy and removing waste while maintaining a steady environment for all body cells. This edition presents foundational concepts about the heart, vessels, and the blood’s work in sustaining life.
The book explains the components of blood, how red and white cells function, and the role of platelets in clotting. It describes how the membrane of red blood cells controls what passes in and out, how hemoglobin carries oxygen, and how different forms of hemoglobin interact with oxygen and carbon dioxide. You’ll also learn about the pulse as a record of heart action, what shifts its pattern, and how the lungs connect to the rest of the circulation. The text ties these ideas to practical ideas about how the body responds to changes in volume, pressure, and respiration.
- How blood transports nutrients, energy, and waste to keep tissues in balance
- Details on red cells, white cells, and platelets and how they behave
- How oxygen is carried, released, and how carbon monoxide and other forms alter blood chemistry
- How the pulse and blood pressure reveal the heart’s strength and the state of circulation
Ideal for readers seeking a clear, foundational view of physiology and the circulation in health and disease.
