Description

"The formation and discharge of urine" PPT

Part One: Learning Objectives

1. Know the composition of the urinary system; understand the structure of the kidneys and the structural characteristics related to urine formation.

2. Be able to describe the process of urine formation and excretion.

3. Explain the meaning of urination and develop good urinary system hygiene habits.

The formation and discharge of urine PPT, part 2 content: course exploration

Explore theme one

components of urinary system

Observe the kidneys

1. Describe the external shape of the kidney.

2. Observe the renal artery, renal vein, and ureteral opening connected to the renal hilum.

3. Cut open the kidney and observe its internal structure: identify the cortex, medulla, and renal pelvis.

1. Kidney

1. Position and form

Located on the posterior wall of the human abdominal cavity and both sides of the spine; broad bean shape;

At the renal hilum are the renal veins, renal arteries entering and exiting the kidneys, and the connection between the ureters and the kidneys.

2. Structure of the kidneys

Cortex: Peripheral, rich capillaries, dark color

Medulla: Medial, light colored

Renal pelvis: The cavity in the center of the kidney where urine collects

2. Ureter, bladder and urethra

kidneys produce urine

ureter carries urine

Bladder temporarily stores urine

urethra discharges urine

Analyze several indicators of urine components

Explore theme two

formation of urine

1. Glomerular filtration-formation of original urine

There are no blood cells and macromolecular proteins in raw urine, and other components are the same as plasma.

2. Renal tubular reabsorption—formation of urine

Most of the water, some inorganic salts, all glucose and other nutrients in the original urine are reabsorbed by the renal tubules into the capillaries. The remaining material flows out of the renal tubules to form urine, which flows to the renal pelvis.

think:

1. Where does blood type change?

2. A patient has blood cells and protein in his urine. Where is the possible location of the disease in his kidney?
