Theme 07: The Circulatory System and Excretory System Course Summary

In this theme, we explore the intricacies of the circulatory system, which plays a crucial role in transporting essential substances throughout the body. We also delve into the excretory system, responsible for eliminating waste products from the body and maintaining internal balance.

Blood and Blood Groups
– Discover the vital role of blood as a complex fluid that delivers oxygen, nutrients, and more to cells.

– Explore its structure, function, and the circulation of oxygenated and deoxygenated blood.

Lymphatic System
– Understand the lymphatic system’s role in immunity and fluid balance.
– Explore lymph nodes and their function in filtering and fighting infections.

The Excretory System
– Examine the different types of waste products produced by the body.
– Discover the various excretory organs within the human body, such as the kidneys, ureters, bladder, and urethra.

Excretion in Humans
– Gain insight into the mechanisms of urine formation, including filtration, reabsorption, and secretion.
– Understand the significance of the excretory system in maintaining a stable internal environment.

Haemodialysis
– Learn about the process of haemodialysis, a life-saving medical procedure used to filter blood and remove waste products in individuals with kidney dysfunction.
– Understand the technology and medical importance of haemodialysis in maintaining health.

This theme provides a comprehensive understanding of how our circulatory and excretory systems work together to support human life and maintain internal balance.
