Chapter 13: Homeostasis and Urinary System of Humans
What you need to learn in this chapter
In this chapter, we will learn about homeostasis and the urinary system of humans. Homeostasis refers to the body's ability to maintain stable physical and chemical factors in the internal environment. We will discuss why it is important for our body to maintain these factors. Next, we will focus on the urinary system. We will learn about the structure and functions of the kidney, which is an important organ in the urinary system. We will also study the structure of a nephron and collecting duct, and understand their roles in the filtration and reabsorption of waste products. Lastly, we will explore health issues related to the urinary system. We will discuss common problems such as urinary tract infections, kidney stones, and kidney failure. By the end of this chapter, we will have a better understanding of how our body maintains homeostasis and the importance of a healthy urinary system.
