Step-by-Step Guidance for BIO 173 Anatomy and Physiology II: Urinary System Study Guide

Q1. List the various functions of the urinary system.

Background

Topic: Urinary System Overview

This question tests your understanding of the primary roles the urinary system plays in maintaining homeostasis and overall body function.

Key Terms:

• Homeostasis

• Excretion

• Osmoregulation

• Acid-base balance

• Blood pressure regulation

Step-by-Step Guidance

1. Start by recalling the main purpose of the urinary system in the body, focusing on waste removal and fluid balance.

2. Think about how the urinary system helps regulate the composition of blood, including the removal of metabolic wastes like urea and creatinine.

3. Consider the system's role in maintaining electrolyte balance, water balance, and acid-base balance.

4. Remember that the kidneys also play a part in regulating blood pressure and producing hormones (such as erythropoietin and renin).

Q2. Describe the structures of the urinary system and their associated functions.

Background

Topic: Anatomy of the Urinary System

This question assesses your ability to identify the organs of the urinary system and explain what each does.

Key Terms:

• Kidneys

• Ureters

• Urinary bladder

• Urethra

Step-by-Step Guidance

1. List the four main organs of the urinary system.

2. For each organ, briefly describe its location in the body.

3. Explain the primary function of each organ (e.g., filtration, transport, storage, elimination).

4. Think about how these structures work together to produce and eliminate urine.

Q3. Identify the gross anatomical features of the kidney, both internal and external.

Background

Topic: Kidney Anatomy

This question focuses on your ability to recognize and describe the major anatomical landmarks of the kidney.

Key Terms:

• Renal cortex

• Renal medulla

• Renal pelvis

• Renal capsule

• Renal pyramids

• Hilum

Step-by-Step Guidance

1. Begin by identifying the external features of the kidney, such as its shape, location, and the renal capsule.

2. Move to the internal features, describing the cortex, medulla, pyramids, columns, and pelvis.

3. Consider the path of blood flow and urine through these structures.

4. Think about how these features are organized and their functional significance.

Q4. List the structures that urine passes through in order to be voided from the body.

Background

Topic: Pathway of Urine Flow

This question tests your knowledge of the sequential pathway urine takes from its formation to elimination.

Key Terms:

• Nephron

• Collecting duct

• Renal pelvis

• Ureter

• Urinary bladder

• Urethra

Step-by-Step Guidance

1. Start with the nephron, where urine is first formed.

2. Trace the path through the collecting duct system.

3. Continue through the renal pelvis and into the ureter.

4. Follow the path into the urinary bladder and finally out through the urethra.

Q5. Briefly list the vessels blood passes through before and after the glomerulus.

Background

Topic: Renal Circulation

This question examines your understanding of the blood supply to and from the glomerulus within the nephron.

Key Terms:

• Afferent arteriole

• Glomerulus

• Efferent arteriole

• Peritubular capillaries

• Vasa recta

Step-by-Step Guidance

1. Identify the main artery that brings blood to the kidney (renal artery).

2. List the sequence of vessels leading to the glomerulus (ending with the afferent arteriole).

3. Describe the vessels blood passes through after leaving the glomerulus (starting with the efferent arteriole).

4. Consider the differences in blood flow for cortical versus juxtamedullary nephrons.
