Important Renal Anatomy and Physiology - Chapter Summary and Learning Objectives

While most people are aware of the kidneys' role in removing waste from the body, you might not be as familiar with how they work to regulate blood pressure and control blood chemistry. Find out which kidney structures are responsible for these tasks with the video lessons included in this chapter. Instructors can walk you through important kidney functions and give you a refresher on the components of the urinary system. This chapter is designed to teach you about:

  • Hormones secreted in the nephron
  • Factors affecting glomerular filtration rate
  • Materials reabsorbed in the renal tubule
  • Enzymes controlling the RAAS

Video Objectives
Gross Anatomy of the Urinary System Examine how the liver, kidneys, bladder, ureters and urethra detoxify the body by filtering blood and removing waste.
The Kidney: Major Divisions & Structures Identify components of the kidneys' renal cortex, renal medulla and renal pelvis.
The Nephron: The Glomerulus's Major Structures and Functions Explore the network of capillaries by which blood enters the glomerulus. Learn about the types of ions and molecules filtered back into the bloodstream.
Supportive Structures of the Nephron: Functions and Definitions Find out which kidney structures and cells regulate the hormones used to control blood pressure, the production of red blood cells and the glomerular filtration rate.
The Renal Tubule: Definition, Function & Terms Survey components of the renal tubule and identify their role in reabsorbing water and minerals, regulating electrolyte balance and maintaining urine pH.
Renin Angiotensin Aldosterone System (RAAS): Pathway, Functions & Terms Study the organs, enzymes and hormones that help regulate blood pressure and water absorption. Discover the feedback loops used to keep these processes under control.

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.

The Nephron: The Glomerulus's Major Structures and Functions

3. 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

4. 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.

The Renal Tubule: Definition, Function & Terms

5. 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

6. 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.
