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.

How Kidney and Metabolic Disease Affect Kidney Function

11. How Kidney and Metabolic Disease Affect Kidney Function

This lesson explores chronic kidney disease and the metabolic disorders that affect kidney function. We'll delve into diabetes mellitus, hypertension, and glomerulonephritis and learn what your urine can tell you about your health.
