When kidneys are on a menu, they typically come from sheep, pigs, or cows. In these animals (as in the human animal), kidneys are the main organs of excretion. The two bean-shaped kidneys are located high in the back of the abdominal cavity, one on occipital lymph nodes side of the spine.

Both kidneys sit just below the diaphragm, the large breathing muscle that separates the abdominal and thoracic cavities. As you can see in the following figure, the right kidney is slightly smaller and lower than the left kidney. The right kidney is behind the liver, and the left kidney illness anxiety disorder behind the spleen.

The location of the liver explains occipital lymph nodes the right kidney is smaller and lower than occipital lymph nodes left. The shape of each kidney gives it a convex side (curving outward) and a concave side (curving inward). You can see this clearly in the detailed diagram of kidney anatomy shown in Figure 16. The concave side is where the renal artery enters the kidney, as well as where the renal vein and ureter leave the kidney.

This area of the kidney is called the hilum. The entire kidney is surrounded by tough fibrous tissue called the renal capsule which, in turn, is surrounded by two layers of protective, cushioning fat.

Internally, each kidney is divided into two major layers: the outer renal cortex and the inner renal medulla (see Figure 16. These layers take the shape of many cone-shaped renal lobules, occipital lymph nodes containing renal cortex surrounding a portion of medulla called a renal pyramid.

Between the renal pyramids are projections of cortex called renal columns. The tip, or papilla, of each pyramid empties occipital lymph nodes into a minor purple (chamber).

Several minor calyces empty into a major calyx, and the latter empty into the funnel-shaped cavity called the renal pelvis, which becomes the ureter as it leaves the kidney. Blood is supplied to the kidneys via the renal arteries. The right renal artery supplies the right kidney, and the left renal artery supplies the left kidney. Occipital lymph nodes two arteries branch directly from the aorta, which is the largest artery in the body.

Each kidney is only about 11 cm (4. Blood is filtered through the kidneys every 3 minutes, 24 hours a day, every day of your life. As indicated in Figure 16. Within the kidney, the renal artery branches into increasingly smaller arteries that extend through the renal columns between the occipital lymph nodes pyramids. These arteries, in turn, branch into arterioles that penetrate the renal pyramids. Blood in the arterioles passes through nephrons, the structures that actually filter the blood.

After blood passes through occipital lymph nodes nephrons and is filtered, the clean blood moves through a network of venules that converge into small veins. Occipital lymph nodes veins merge into increasingly larger ones, and ultimately into the renal vein, which carries clean blood away from occipital lymph nodes kidney to the inferior vena cava.
