Each kidney is held in place by connective tissue called renal fascia and surrounded by a thick layer of fatty tissue called adipose fat that helps protect it. The tough, fibrous connective tissue renal capsule closely envelops each kidney and supports the soft tissue inside.
What anatomical structures provide protection to the kidney quizlet?
The renal capsule is a smooth, transparent fibrous membrane that surrounds, encloses, and protects the kidney. Each kidney has its own renal capsule, or outer layer, which helps maintain the kidney’s shape and protect it from damage.
Which structure covers the outer surface of the kidney and provides protection?
The renal capsule, a thin membranous sheath covering the outer surface of each kidney. The capsule is composed of tough fibers, primarily collagen and elastin (fibrous protein), that support the kidney mass and protect vital tissue from damage.
What are the main anatomical structures of the kidney?
Inside the kidney are many pyramidal lobes. Each is composed of the outer renal cortex and the inner renal medulla. Nephrons flow between these sections. Each nephron contains a filter called a glomerulus and a tubule.
What is the protective layer of the kidney called?
The renal capsule is a tough fibrous layer that surrounds the kidney and is covered with a layer of terminal fat known as the renal fat capsule. The fat capsule may be included in the structure of the renal capsule. They provide protection from trauma and injury.
Are the kidneys protected by the ribs?
They are part of your internal organs. They are located on the back on both sides of your spine. Your kidneys are protected by your rib bones.
What is external structure of kidney?
External Structure of the Kidney Your kidneys are bean shaped and dark red in color. One side bulges outward (convex) and the other side is indented (concave). The indented or concave section is known as the hilum. This is where the renal artery, renal vein, and ureter enter/exit the kidney.
Which of the following is the outermost layer of the kidneys?
The outermost layer is a tough connective tissue layer called the renal fascia. The second layer is called the perirenal fat capsule and helps hold the kidney in place. The third inner layer is the renal capsule.
What is the structure and function of the kidney?
They are located just below the rib cage, one on each side of the spine. Healthy kidneys filter about half of the blood every minute, removing waste products and excess water to produce urine. Urine flows from the kidneys to the bladder through two thin tubes of muscle, one on each side of the ureter, called the ureters.
What is the function of the hilum in the kidney?
Each renal artery enters the kidney at a region of the kidney called the renal artery. This area is the outlet and exit for the blood vessels and nerves that feed the kidneys. From there, the arteries branch off into smaller vessels throughout the kidney.
What is the function of medulla in kidney?
The main function of the medulla is to regulate the concentration of urine. Urine flows from the collecting ducts to the renal calyces and pelvis, where it undergoes unilateral per movement, allowing drainage of urine downstream to the ureters and bladder.
Are kidneys covered by peritoneum?
Surgical Anatomy The peritoneum is a closed cavity containing all abdominal organs except the kidneys and adrenal glands. The parietal peritoneum covers the abdominal wall and diaphragm.
What is the name of the outer section of tissue in the kidney quizlet?
The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla.
Which of the following anchors the kidney to the surrounding structures?
– Renal fascia: the dense fibrous outer layer that anchors the kidney to the surrounding structures.
What type of tissue makes up the kidney?
The parenchyma of the kidney is the epithelial tissue (primarily the renal tubules). Supporting the blood vessels, nerves, and connective tissue of the kidney comprise the interstitium.
Where is the kidney located anatomically?
The kidneys are a pair of bean-shaped organs located on either side of the spine, under the rib bones and behind the belly. Each kidney is about 4 to 5 inches long, roughly the size of a large fist.
What is the renal hilum quizlet?
The hilum is where the ureter exits the kidney. The hilum is the concave clasp of the kidney.
What is the function of medullary pyramid?
Function. The medullary pyramid contains the motor fibers of the pyramidal tract, the corticospinal and corticospinal bodies.
What is the difference between the renal cortex and medulla?
The renal medulla is the innermost part of the kidney. It is divided into smaller sections called the renal pyramid. The difference between the renal cortex and the renal medulla is that the renal cortex is the outer portion of the kidney, whereas the renal medulla is the innermost portion of the kidney.
What structures are found in the renal columns quizlet?
These renal columns are where the interlobar arteries are located. A cavity within the kidney that is continuous with the ureter exiting the hilus. The pelvis contains an area that extends toward the apex of the renal pyramid.
Which of the following structures is located at the renal hilum quizlet?
The renal pyramid is where the three vessels attach to the kidneys. The ureter, renal artery, and vein are the three vessels that make up the kidney of the kidney.
Which of the following organs is protected by the peritoneum?
Peritoneal Relations The intra-abdominal organs are completely encased by the visceral peritoneum. These organs are the liver, spleen, stomach, upper part of the duodenum, jejunum, ileum, transverse intestine, sigmoid colon, and upper part of the rectum.
What is the difference between retroperitoneal and peritoneal?
The peritoneum and retroperitoneum refer to the various spaces within the abdominal cavity and the organs supported, protected, and nourished by these spaces. The retroperitoneal spaces and organs are found behind the peritoneal spaces, with only the anterior wall covered by the parietal (JanaVasković).
What is the function of peritubular capillaries?
Cortical capillaries are small blood vessels in the kidneys. They filter waste products from your blood so waste products can pass through your body into urine (pee). Cortical capillaries also reabsorb minerals and other nutrients your body needs to function properly.
What causes injury to the kidney?
Causes of Acute Kidney Injury Heart failure, liver failure, or sepsis results in the heart pumping out less blood than normal. Vascular problems – such as inflammation or blockage of blood vessels in the kidneys (a rare condition called vasculitis)
What is the function of the renal cortex quizlet?
The renal cortex receives most of the blood flow and is primarily concerned with reabsorbed filtered material. The medulla is a highly metabolically active region and helps concentrate urine. The renal pelvis is a funnel-shaped reservoir that collects urine and passes it to the ureter for excretion.
What are the names and locations of the layers in the kidney?
The kidneys are composed of three major sections Each kidney is composed of the outer renal cortex, the inner renal medulla, and the renal pelvis. Blood is filtered through the renal cortex. The renal medulla contains the renal pyramids where urine formation occurs. Urine passes from the renal pyramid to the renal pelvis.
What surrounds the kidneys to help protect them from trauma and anchor them in place?
Renal fascia: the outermost layer. It anchors the kidneys to the abdominal wall and surrounding structures.

1 Answer. The renal tubules are lined by a simple epithelium.
What are kidney anchors?
Externally, the kidney is surrounded by three layers shown in Figure 2. The outermost layer is a tough connective tissue layer called the renal fascia. The second layer, called the perirenal fat capsule, helps anchor the kidney in place.
What is the major artery that supplies the kidney?
The renal arteries are large blood vessels that carry blood from the heart to the kidneys. Renal is another word for kidney. There are two renal arteries. The right renal artery supplies blood to the right kidney and the left artery sends blood to the left kidney.
What is the physiological anatomy of the kidney?
The functional substance, or parenchyma, of the human kidney is divided into two main structures: the outer renal cortex and the inner renal medulla. As a whole, these structures are in the form of 8 to 18 conical renal lobes, each containing a renal cortex surrounding a portion of the medulla called the renal cone.
