What are the functioning units of the kidneys?
The nephron is the functional unit of the kidneys. Each human kidney has around 1.2 million nephrons, which are hollow tubes made up of a single cell layer. A renal corpuscle, proximal tubule, loop of Henle, distal tubule, and collecting duct system comprise the nephron (Figure 2-2).
What is the functional unit of filtration in the kidney?
The nephron is the functional unit of the kidney. Each nephron is composed of a renal corpuscle, the initial filtering component; and a renal tubule that processes and carries away the filtered fluid.
What are the function of the kidneys quizlet?
What do the kidneys do? they extract waste from blood, balance body fluids, form urine, and aid in other important functions of the body. against the back muscles in the upper abdominal cavity, opposite each other on either side of the spine.
Why is the kidney supplied with large blood vessels?
Kidney function is highly dependent upon sufficient blood pressure in the glomeruli. The arteries and arterioles that provide blood flow to the kidneys must maintain sufficient blood flow to keep the tissues of the kidneys alive and also maintain sufficient blood pressure to allow wastes to be separated from the blood.
What are the functions of the urinary system quizlet?

Where does filtration take place in the nephron?
Filtration. Filtration takes place in the glomerulus , which is the vascular beginning of the nephron . Approximately one-fourth of the blood flow from cardiac output circulates through the kidney, the greatest rate of blood flow for any organ .
What are the 7 functions of the kidney?
The 7 functions of the kidneys A – controlling ACID-base balance. W – controlling WATER balance. E – maintaining ELECTROLYTE balance. T – removing TOXINS and waste products from the body. B – controlling BLOOD PRESSURE. E – producing the hormone ERYTHROPOIETIN. D – activating vitamin D.
What are the 3 major functions of the urinary system?
The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
What is the kidney structure?
The bean-shaped kidneys have an outer convex side and an inner concave side called the renal hilus, where the renal artery, vein, and ureter are found. A thin connective tissue called the renal capsule surrounds each kidney. This capsule maintains the kidneys' shape and protects the inner tissues.
How do kidneys function?
Proper kidney structure and function is dependent on adequate blood supply: 1 The renal artery, which branches out from your abdominal aorta enters the kidney in the renal hilus. 2 Each renal artery divides into the smaller afferent arterioles in the kidney. 3 The afferent arterioles in the renal cortex separate into bundles of capillaries called glomeruli. 4 Each glomerulus recollects into a smaller efferent arteriole that descends into the renal medulla. 5 Each efferent arteriole separates into peritubular capillaries near the renal tubules. 6 Peritubular capillaries merge, forming veins that drain into the renal vein. 7 The renal vein exits each kidney to join the inferior vena cava, which transports blood back to your heart.
What are the functions of the urinary system?
The urinary system depends on proper kidney structure and function. Some of these core actions include: 1 Excretes waste: The kidneys get rid of toxins, urea, andexcess salts. Urea is a nitrogen-based waste product of cell metabolism that is produced in the liver and transported by the blood to the kidneys. 2 Maintains water balance: The kidneys help maintain water and electrolyte balance in the body. They react to changes in the water level, which may increase or decrease throughout the day. 3 Regulates blood pressure: The kidneys help regulate blood pressure by producing angiotensin, a substance that constricts blood vessels and signals the body to retain waterand sodium when blood pressure is low. 4 Regulates red blood cells: The kidneys produce erythropoietin, a hormone that stimulates your bone marrow to produce more red blood cells when the bodydoes not get enough oxygen. 5 Regulates acid levels: Acids are products of metabolism. The kidneys help maintain proper acid-base balance to keep the body healthy.
What is the kidney capsule?
A thin connective tissue called the renal capsule surrounds each kidney. This capsule maintains the kidneys' shape and protects the inner tissues.
What is the outer layer of the kidney?
This capsule maintains the kidneys' shape and protects the inner tissues. Inside the renal capsule is the outer layer called the renal cortex, asoft, dense, and vascular tissue. Deep to this layer is the renal medulla, which consists of several renal pyramids, ...
Where does urine drain into the kidney?
From here, urine drains into the larger ureter. Here’s a summary of kidney structure and function based on different parts of the kidney: An indentation near the center of the concavity of the kidney where the renal vein and ureter leave the kidney and the renal artery enters the kidney.
How many nephrons are there in the kidney?
There are about a million nephrons in each kidney. Collecting duct. The part of the kidney nephron that collects urine and drains into papillary ducts, minor calyx, and major calyx, and finally into the ureter and urinary bladder. Ureter. The structure which conveys urine from the kidney to the urinary bladder.
