Ch 28: Urinary Systems & Structures

About This Chapter

The lessons in this chapter are made to help you comprehend more about the urinary system and its structure and function. You can explore lessons about specific parts of the urinary system, then take the quizzes to assess your level of comprehension.

Urinary Systems & Structures- Chapter Summary

Use the lessons provided in this chapter to help you better understand the significant areas of the urinary system and how they function. This will be beneficial to you if you would like to learn how the body works. After completing this chapter, you should be comfortable with your ability to:

  • Identify the anatomy of the urinary of the urinary system
  • Recall the role of the kidneys
  • Review what the nephron is
  • Discuss the function of the glomerular filtration rate
  • Explain the terms related to the renal tubule
  • Detail the pathway of the renin angiotensin aldosterone system
  • Describe how the kidneys regulate water and acid base balance in the body

As you prepare to learn more about how the body works, you can take advantage of the resources in this chapter. There are quizzes paired with every lesson in this chapter that will test you on your understanding of the material. Students can also take the chapter test to further assess their comprehension. A benefit of using our resources is that it is all online, which gives you flexibility and convenience.

Gross Anatomy of the Urinary System

1. Gross Anatomy of the Urinary System

Our body must detoxify and cleanse itself to thrive. That is why we depend so heavily on our liver and urinary system. In this lesson, we'll explore how toxins are filtered by our organs and how urine is formed and expelled with the nephron, bladder, ureters, and urethra.

The Kidney: Major Divisions & Structures

2. The Kidney: Major Divisions & Structures

Learn about the major layers of the kidneys, like the renal cortex and renal medulla. Find out about the inner parts of the kidneys, including the renal papilla, renal pelvis, renal pyramid, and renal hilum.

Blood Supply of the Kidneys

3. Blood Supply of the Kidneys

Follow the blood supply of the kidneys through the aorta and into the renal artery, then delve deeper into the blood supply as we look into the arcuate artery, interlobar artery, and interlobular artery. Finally, we will find out the function of the renal vein.

The Nephron: The Glomerulus's Major Structures and Functions

4. The Nephron: The Glomerulus's Major Structures and Functions

Together, the glomerulus and Bowman's capsule make up the renal corpuscle of the nephron. These parts of the nephron filter blood and are vital to our body's survival. In this lesson, you'll explore the major corpuscular structures and their functions.

Supportive Structures of the Nephron: Functions and Definitions

5. Supportive Structures of the Nephron: Functions and Definitions

In this lesson, you'll learn about the supportive structures of the nephron, including the juxtaglomerular apparatus, juxtaglomerular cells, macula densa, and mesangial cells. You'll also explore enzymes and hormones like renin and erythropoietin and learn why they are so important to the body.

What is the Glomerular Filtration Rate? - Definition, Function & Terms

6. What is the Glomerular Filtration Rate? - Definition, Function & Terms

Forces known as hydrostatic pressure and oncotic pressure help to increase and decrease your glomerular filtration rate. Find out what the GFR is and how these forces influence it.

The Renal Tubule: Definition, Function & Terms

7. The Renal Tubule: Definition, Function & Terms

Renal tubules are essential structures in the kidneys. This lesson explores the function of the renal tubule and its parts, including the proximal and distal convoluted tubules, the loop of Henle, and the collecting duct. Learn how these components work together to absorb materials and form urine.

Renin Angiotensin Aldosterone System (RAAS): Pathway, Functions & Terms

8. Renin Angiotensin Aldosterone System (RAAS): Pathway, Functions & Terms

The renin-angiotensin-aldosterone system is one of the most complex and important systems in controlling the blood pressure in your body. As we go over this system, you'll also learn about the many hormones involved in the control of your body's glomerular filtration rate and blood pressure.

How the Kidneys Regulate Water Balance

9. How the Kidneys Regulate Water Balance

Water balance is essential to our health and survival. This lesson explores how the kidneys regulate water balance with special cells known as osmoreceptors and a process called osmoregulation. You'll also learn how this process relates to a rare form of diabetes known as diabetes insipidus.

How the Kidneys Regulate Acid Base Balance

10. How the Kidneys Regulate Acid Base Balance

Find out how your kidneys keep you alive by excreting acids and bases in conditions like respiratory acidosis, metabolic alkalosis, metabolic acidosis, and respiratory alkalosis.
