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

The urinary system is comprised of several organs that perform critical roles in the detoxification of the body and the excretion of toxins in the form of urine. Learn about the anatomy of the urinary system (liver, kidneys, nephrons, ureters, bladder, & urethra), the purpose of each organ, and how the urinary system functions to eliminate waste from the body.

The Kidney: Major Divisions & Structures

2. The Kidney: Major Divisions & Structures

The kidney is a complex organ that helps the human body function properly by removing urine and excess fluid, and also by regulating minerals and removing waste from the blood. Learn about the functions of the kidney's major divisions and structures including the cortex, medulla, renal pyramid, renal papilla, and renal pelvis.

The Nephron: The Glomerulus's Major Structures and Functions

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

One job of the nephron is to filter blood to the kidneys, which helps promote the human body's health and survival. Learn about the nephron and explore the glomerulus' major structures and functions. Review cardiac output to the kidneys, Bowman's capsule, renal corpuscle, afferent and efferent arteriole, and ultrafiltration.

Supportive Structures of the Nephron: Functions and Definitions

4. Supportive Structures of the Nephron: Functions and Definitions

Some cells in the kidneys play roles in regulating blood pressure and kidney blood flow. Explore the functions of the supportive structures of the nephron, like the juxtaglomerular (JG) apparatus and its JG, macula densa, and mesangial cells.

The Renal Tubule: Definition, Function & Terms

5. The Renal Tubule: Definition, Function & Terms

The kidneys include renal tubules, which are essential structures that help the kidneys function properly. Learn the definition of the renal tubule and explore its functions, including the role of PTH in regulating calcium. Understand terms important to the renal tubule, including ultrafiltrate, proximal convoluted tubule, loop of Henle, distal convoluted tubule, connecting tubule, the collecting duct and its hormones, and distal nephron and its hormones.

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

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

The renin angiotensin aldosterone system (RAAS) controls blood pressure and glomerular filtration rate using enzymes like renin and hormones like angiotensin I and II and aldosterone. Explore the pathways, functions, and terms of the RAAS.
