The triangular shaped areas of the renal medulla are the what?
Renal Pyramids - The renal medulla consists of 6 to 18 distinct conical or triangular structures called renal pyramids.
What parts of the nephron is found in the renal medulla?
Most nephrons (85%) are contained withing the renal cortex. The remaining 15% are called juxtamedullary nephrons and their glomeruli are close to the corticomedullary border. Their loops of Henle are found within the renal medulla.
What are nephrons called if they are located mainly in the cortex?
cortical nephrons
What is the function and location of the nephrons?
The nephrons are found in the kidneys (about 1 million in each kidney). These structures are responsible for filtering the blood and then reabsorbing wanted substances further down the nephron. Blood reaches the top of the nephron (called the glomerulus), and the smaller molecules, such as glucose, water, urea and ions diffuse across the glomerular membrane. Further down the nephron, at the convoluted tubules, the glucose and some of the water and ions are reabsorbed back into the bloodstream, either by diffusion or by active transport, if the substances need to go against a concentration gradient. What's left in the nephron is a mixture of excess water and ions, as well as the toxin urea. These pass out of the nephron and through the ureters into the bladder, as urine.
Which part of the brain controls The cardiac and respiratory centers for the body?
Lots of areas of the nervous system are. The brainstem (medulla) helps control heart rate, but the heartbeat itself doesn't depend on the nervous system at all.Autonomic nervous system controls circulation by acting on muscles that surround arteries, and smaller vessels.One of the things that influences which capillaries are open is body temperature, which is controlled in a part of the brain called the hypothalamus.

What are nephrons and why are they important?
Nephrons are the smallest functional filtering units of the kidneys. They are located in the adrenal cortex (outer crust) which is considered the urine manufacturing facility. The adrenal medulla (inner core) is the urine collecting facility. The urine then goes into the renal pelvis which leads to the ureters, tubes that lead to the bladder where it is stored until you urinate. The urine then leaves your body through your urethra. Medically this is called micturition. See the link below: This is a complete nephron. ( Αdrenal medulla ?? )
What is a tiny filtering unit in the kidney?
The filtering unit of the kidney is the nephrons.
What are the cortical tissues located between the pyramids?
fibrous column The answer you are looking for is: renal column
What are the filters inside a kidney called?
The filtering units within the kidney are called nephrons.
How is the interior of the kidney constructed?
The kidney is divided into two sections:an outer layer, the cortex, and an inner layer:the medulla. the medulla is divided into triangular shaped wedges called renal pyramids with bases toward the cortex and "tops", or renal papillae, emptyng into cavities called calyces.
True or False The kidney is composed of two blood filtering units called nephrons?
Tiny cells in the kidneys called nephrons filter the blood, they are composed of the glomerulus and the tubule. You have thousands of nephrons in each kidney.
Striped appearing structures formed primarily of collecting ducts?
The striped looking structures that collect ducts is called medullary pyramids. This structure is the content of the ventral part of medulla oblongata.
What are the parts of the kidney?
The outer, reddish region, next to the capsule, is the renal cortex. This surrounds a darker reddish-brown region called the renal medulla. The renal medulla consists of a series of renal pyramids, which appear striated because they contain straight tubular structures and blood vessels. The wide bases of the pyramids are adjacent to the cortex and the pointed ends, called renal papillae, are directed toward the center of the kidney. Portions of the renal cortex extend into the spaces between adjacent pyramids to form renal columns. The cortex and medulla make up the parenchyma, or functional tissue, of the kidney. The central region of the kidney contains the renal pelvis, which is located in the renal sinus and is continuous with the ureter. The renal pelvis is a large cavity that collects the urine as it is produced. The periphery of the renal pelvis is interrupted by cuplike projections called calyces. A minor calyx surrounds the renal papillae of each pyramid and collects urine from that pyramid. Several minor calyces converge to form a major calyx. From the major calyces the urine flows into the renal pelvis and from there into the ureter.Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla). The nephrons make up the bulk of the kidney tissue and join up with larger collecting tubes that eventually form the main urine-carrying duct - the ureter Each kidney has an indentation, called the hilum, on the medial side. The hilum leads to a large cavity, called the renal sinus, within the kidney. The ureter and renal vein leave the kidney, and the renal artery enters the kidney at the hilum.Malphigian body can be further divided into glomerulus and bowman's capsule,whereas renal tubules can be divided into proximal convoluted tubule, loop of henle, distal convoluted tubule and collecting tubule.
