PHYS20030 An Introduction to Physiology: Organs and Systems

Academic Year 2024/2025

This module serves as an introduction to major organ systems that contribute to the ‘constancy of the internal environment’ of an organism. This control of the internal environment is known as homeostasis. Physiologically, homeostasis is the body's attempt to maintain a constant and balanced internal environment for living processes to take place, which requires persistent monitoring and adjustments, as external and internal conditions change. The major organ systems covered include:
1. The Cardiovascular System.
2. The Respiratory System.
3. The Gastrointestinal System.
4. The Urinary System.
5. The Endocrine System.

Learning Outcomes:

On successful completion of this module students should be able to:
Describe the structure and function of heart and blood vessels; describe the structure and function of the airways; describe the mechanisms of gas exchange and transport; explain how food is digested and absorbed; describe the structure and functions of the kidneys and urinary system; describe the principal endocrine glands and their basic functions; explain how the actions of the major body systems contribute to the function of homeostasis.

Indicative Module Content:

This module serves as an introduction to the major organ systems that contribute to the ‘constancy of the internal environment’ of an organism. This control of the internal environment is known as homeostasis. Physiologically, homeostasis is the body's attempt to maintain a constant and balanced internal environment for living processes to take place, which requires persistent monitoring and adjustments, as external and internal conditions change. The major organ systems covered include:
1. The Cardiovascular System, including the structure and function of the heart, blood vessels, lymphatic vessels.
2. The Respiratory System component, including the structure and function of the lungs including the exchange of gases in the airways.
3. The Gastrointestinal (GIT) System, including the structure and function of the GIT including food digestion and absorption of nutrients.
4. The Urinary System, including the structure and function of the kidneys, ureters and urinary bladder and examining the role the kidneys play in regulating solute and water content in the body.
5. The Endocrine System, including the structure and function of the principal endocrine glands.
