Part One: Course Knowledge Points

Knowledge point 1: The kidney is an important organ of the urinary system

1. Functions of each component organ of the urinary system

2. Structure of the kidneys

(1)Structure of kidney

①The renal hilum is the site where the renal vein and renal artery enter and leave the kidney, and where the ureter and the kidney connect.

②The kidney is divided into three parts: cortex, medulla and renal pelvis. The cortex is darker due to the rich capillaries, and the medulla is lighter. The renal pelvis is the cavity in the center of the kidney.

(2) Nephron, the basic unit of kidney structure and function

① The glomerulus is a vascular bulb formed by dozens of capillaries branching off from the afferent arteriole. These capillaries merge into an efferent arteriole before exiting the renal corpuscle.

② The glomerulus is surrounded by the renal capsule, the inner layer is close to the glomerulus, and the renal capsule cavity is between the inner and outer layers. Glomeruli and glomeruli are mainly located in the cortical part of the kidney.

③ Renal tubules are mainly distributed in the medulla of the kidney, and there is a capillary network connected with the efferent arteriole on the outside. A large number of renal tubules merge into larger tubes that flow into the renal pelvis.

Knowledge point 2: Urine is formed in the nephron

Special reminder (1) The glomerulus is a special capillary bulb, and the blood vessels connected to both ends are arterioles.

(2) Under normal circumstances, compared with plasma, raw urine does not contain macromolecular proteins; compared with raw urine, urine does not contain glucose.

(3) Compared with the blood in the afferent arteriole, the concentration of blood cells and macromolecular proteins in the blood in the efferent arteriole is increased.

(4) Venous blood containing very little urea flows in the renal vein.

PPT on the formation and discharge of urine, part 2: detailed explanation of textbook questions

Activity "Observing the Kidney" Discussion Questions

1.How many parts is the structure of the kidney divided into?

Tip: The structure of the kidney includes three parts: renal pelvis, cortex and medulla.

2. Which part of the kidney is connected to the ureter?

Tip The ureters connect to the renal pelvis in the kidneys.

3. Observe Figure 11-4. Why is the cortical part of the kidney darker than the medulla?

Tip: Because there are fewer blood vessels in the medulla, the medulla is lighter in color than the cortex, which contains more blood vessels.

Activity "Several Indicators for Analyzing Urine Components" Discussion Questions

1. Compared with normal people, which indicators in this patient’s urine are abnormal?

TIP: The red blood cells, protein, and glucose levels in this patient's urine are abnormal.

2. Infer which structures of this patient’s kidneys have problems?

Tip: It may be that there is a disease in the glomerulus, causing red blood cells and proteins to enter the glomerulus through the glomerulus and be excreted from the body with urine; it may also be that there is a disease in the renal tubules, causing glucose to be unable to be reabsorbed.
