Description

"Composition of Human Urinary System" PPT

Part One: Teaching Objectives:

1. Explain the composition of the urinary system and the functions of each part.

2. Overview the structure and characteristics of the kidney

3. Learn to observe and dissect pig kidneys

Self-study tips:

1. Carefully read the "Composition of the Human Urinary System" on pages 67 to 68 of the book, observe Figure 11-1, and think about what organs the urinary system is composed of and what are their functions?

The composition of the human urinary system PPT, Part 2 content: The composition of the urinary system

Kidney--the place where urine is formed

Ureter--transports urine

Bladder-temporarily stores urine

Urethral--discharge of urine

The main function of the urinary system is the formation and elimination of urine

Think about it:

Which organ is the main organ of the urinary system? What's your reason?

The kidney is the main organ of the urinary system

PPT on the composition of the human urinary system, part three: classroom activities

Activities: Observe and dissect pig kidneys

Activity suggestions:

(1) Overall observation

1. Look: the shape of the kidney--like a broad bean

Kidney color - reddish brown

2. Touch: The surface of the kidney - smooth

Kidney feel--soft

3. Smell: the smell of kidneys--the smell of urine

(2) Longitudinal section observation

Use a scalpel to cut the kidney longitudinally, and observe the internal structure of the kidney by referring to Figure 11-2 on page 68 of the book.

Please summarize

What are the main structural characteristics of the nephron?

1. The glomerulus is a capillary bulb with arteries connected to both ends;

2. One end of the renal capsule wraps the glomerulus, and the other end is connected to the renal tubule. The cavity between the two layers of cells is connected to the renal tubule;

3. The renal tubules are slender and tortuous, surrounded by a network of capillaries, and eventually converge into collecting ducts, which are connected to the renal pelvis.
