Internal Anatomy Of Kidney

There are 8-18 renal pyramids in each kidney that on the coronal section look like triangles lined next to each other with their bases directed toward the cortex and apex to the hilum. In the medulla 5-8 renal pyramids are separated by connective tissue renal columns.

If untreated the resulting damage can lead to total kidney failure.

Internal anatomy of kidney. This is a free printable worksheet in PDF format and holds a printable version of the quiz Internal Anatomy of Kidney By printing out this quiz and taking it with pen and paper creates for a good variation to only playing it online. This is an online quiz called Internal Anatomy of the Kidney. The kidneys are sandwiched between the diaphragm and the intestines closer to the back side of the abdomen.

Numerous tubes and blood vessels located in the cortex make it appear light red and somewhat granular. They are roughly the size of your fist and the male kidney is typically a bit larger than the female kidney. Pararenal fat mainly located on the posterolateral aspect of the kidney.

The most external region is referred to as the renal cortex. Internally the kidneys have an intricate and unique structure. If the front half of the kidney is removed it becomes possible to see that the inside is divided into three major regions or zones.

Each kidney has about 1 million un. The renal columns are connective tissue extensions that radiate downward from the cortex through the medulla to separate the most characteristic features of the medulla the renal pyramids and renal papillae. Not much explanation is needed if all you want to know is what it looks like and what the names of the parts are.

Each pyramid creates urine and terminates into a renal papilla. Roughly the size of a closed fist each kidney measures about 10 to 12 centimeters long 5 to 7 centimeters wide and 3 to 5 centimeters thick. The medulla is composed of a series of conical masses called the renal pyramids.

This quiz has tags. The apex of these pyramids form a papilla which projects into the lumen of the minor calyces. Internal Kidney Anatomy If a human kidney is sliced vertically from top to bottom the intricate structure of the internal anatomy will be revealed.

These are some images from my own textbooksart macro photos and light and electron micrographs. The renal capsule provides a stiff outer shell to maintain the shape of the soft inner tissues. Click on the tags below to find other quizzes on the same subject.

Internal anatomy of the kidney overview The main unit of the medulla is the renal pyramid. Some of these components can be seen with the naked eye and are known as the gross anatomy. 1 Each kidney is connected to the bladder through a ureter.

Gross Anatomy of the Kidney The kidneys lie on either side of the spine in the retroperitoneal space between the parietal peritoneum and the posterior abdominal wall well protected by muscle fat and ribs. Renal fascia also known as Gerotas fascia or perirenal fascia encloses the kidneys and the suprarenal glands. The renal cortex renal medulla and renal pelvis are the three main internal regions found in a kidney.

A thin layer of fibrous connective tissue forms the renal capsule surrounding each kidney. The apex of the pyramid projects medially toward the renal sinus. The pyramids empty into the calyx.

The renal artery is further subdivided into several branches inside the kidney. The renal columns are connective tissue extensions that radiate downward from the cortex through the medulla to separate the most characteristic features of the medulla the renal pyramids. A frontal section through the kidney reveals an outer region called the renal cortex and an inner region called the renal medulla Figure 2512.

Renal Artery branches off of the aorta bringing waste-filled blood into the kidney for filtering in the nephrons. Nephrons masses of tiny tubules are largely located in the medulla and receive fluid from the blood vessels in the renal cortex. There is a printable worksheet available for download here so you can take the quiz with pen and paper.

Medulla inner region of the kidney contains 8-12 renal pyramids. The renal cortex renal medulla and renal pelvis are the three main internal regions found in a kidney. The kidney is composed of an inner medulla and an outer cortex surrounded by a tough fibrous capsule.

Nephrons masses of tiny tubules are largely located in the medulla and receive fluid from the blood vessels in the renal cortex. These internal components are responsible for performing the many essential functions of the kidney. A frontal section through the kidney reveals an outer region called the renal cortex and an inner region called the medulla Figure 258.

The indentation on the concave side of the kidney known as the renal hilus provides a space for the renal artery renal vein and ureter to enter the kidney. Fig 2 The external coverings of the kidney. Severe damage to the kidneys can cause chunks of kidney tissue to break off internally and clog the kidneys.

A frontal section through the kidney Figure 2 reveals an outer region called the renal cortex and an inner region called the renal medulla.
