Urgent need for schematic diagram of internal structure of pig kidney

Schematic diagram of internal structure of pig kidney:

The kidney is a dark red solid organ shaped like a broad bean. The surface of kidney is smooth, which can be divided into upper and lower ends, front and rear sides, and inner and outer edges.

Structural composition:

1. hius renalis: It is a depression in the middle of the medial edge of the kidney, where the renal artery, renal vein, renal pelvis, nerves and lymphatic vessels pass in and out.

3. Renal pedicle: All structures entering and leaving the renal hilum are surrounded by connective tissue, which is called renal pedicle. The right renal pedicle is shorter than the left renal pedicle.

4. Renal sinus: it is a cavity formed by the depression of renal hilum into renal parenchyma. It contains renal calyx, renal calyx, renal pelvis, renal artery branches, renal vein branches, lymphatic vessels, nerves and adipose tissue.

Characteristics of kidney deficiency in pigs;

1, kidney congestion The kidney is swollen, hard, dark, mottled or diffuse red, especially when the glomerulus is congested, obvious red spots can be seen on the renal section. Renal hyperemia is more common in acute inflammation, toxic diseases and compensatory hyperfunction.

2. There are a large number of dark red bleeding spots from the tip of a needle to the size of a grain of rice on the kidney surface and section of classical swine fever pigs, accompanied by bleeding spots with pale skin and different sizes, bleeding at the edge of lymph nodes all over the body, and the section is marble-like.

3, the kidney is not swollen, the texture is soft, the capsule is easy to peel off, and the surface is smooth. The color is grayish yellow, and there are grayish white or yellowish white focal infarcts on the surface of the kidney. Renal infarction is more common in the course of classical swine fever.
