What is the pathway of urine from the kidneys?

Answer 1

Blood flows to the kidney through the renal artery. Once in the kidney the blood flows through a series of smaller and smaller arteries until it gets to the glomerulus. The glomerulus filters blood and to be very simplistic creates a filtrate of the blood or "urine". This urine then flows through a series of progressively bigger tubules and ducts until it gets to the renal pelvis. At this point urine exits the kidney, it enters the ureter (long tube connecting kidney and bladder), and flows into the bladder where it is held until one desires to urinate. At this time urine flows out of the bladder and into the urethra. The urethra connects the bladder to the outside of the body. As blood passes through the renal artery, it also passes through certain complexes that im not going to name. Those complexes are responsible for filtering out all un-needed components in blood. Those fluids flow down renal tubes at the mercy of diffusion. When it reaches the ureter, re-absorbtion takes place where its the body's last chance to make any changes. Once it passes the ureter, it collects in the bladder. All the blood that was passed through the kidney gets returned to the heart via the renal vein.

Answer 2

the kidneys filter blood and the waste goes down through the ureters, the tubes that carry urine to the bladder. the bladder holds urine until you pee it out. the tube that carries urine out of the body is called the urethra. when you are ready to pee, you relax musels in your bladder and the urine flows out through the urethra.

Answer 3

This is in a human body startin at kidneys till it exits the body:

Afferent arteriole--> glomerulus--> glomerular Capsule-->

proximal convulated tubule-->desending limb-->

loop of henle--> ascending limb--> distal convulated tubule-->

collecting duct--> renal papilla--> minor calyx--> major calyx-->

renal pelvis--> uretopelvic junction --> ureter-->

uretovesical junction --> bladder-->

and finally urethra and out it goes.

Answer 4

Urine takes a number of steps before its complete formation . The pathway of urine in the body is starting from the Glomerulus to bowman's Capsule then to proximal tubule , loop of Henle , distal tubule and finally it goes to the collecting duct.

Answer 5

Urine formation and the adjustment of blood composition involve three major processes: glomerular filtration by the glomeruli, and tubular reabsorption and tubular secretion in the renal tubules. In addition, the collecting ducts work in concert with the nephrons to concentrate or dilute the urine..

Functions of the nephrons include filtration, tubular reabsorption, and tubular secretion. Via these functional processes, the kidneys regulate the volume, composition, and pH of the blood, and eliminate nitrogenous metabolic wastes.

Answer 6

Glomerulus --> Bowman's space in Bowman's capsule --> proximal convoluted tubule --> proximal straight tubule --> descending thin limb of Henle's loop --> ascending thin limb of Henle's loop --> thick ascending limb of Henle's loop --> distal convoluted tubule --> cortical collecting duct --> medullary collecting duct --> renal pelvis --> ureter --> urinary bladder --> urethra

Answer 7

Your body takes nutrients from food and uses them to maintain all bodily functions including energy and self-repair. After your body has taken what it needs from the food, waste products are left behind in the blood and in the bowel. The urinary system works with the lungs, skin, and intestines-all of which also excrete wastes-to keep the chemicals and water in your body balanced. Adults eliminate about a quart and a half of urine each day. The amount depends on many factors, especially the amounts of fluid and food a person consumes and how much fluid is lost through sweat and breathing. Certain types of medications can also affect the amount of urine eliminated.

The urinary system removes a type of waste called urea from your blood. Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the bloodstream to the kidneys.

The kidneys are bean-shaped organs about the size of your fists. They are near the middle of the back, just below the rib cage. The kidneys remove urea from the blood through tiny filtering units called nephrons. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.

From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop. Small amounts of urine are emptied into the bladder from the ureters about every 10 to 15 seconds.

The bladder is a hollow muscular organ shaped like a balloon. It sits in your pelvis and is held in place by ligaments attached to other organs and the pelvic bones. The bladder stores urine until you are ready to go to the bathroom to empty it. It swells into a round shape when it is full and gets smaller when empty. If the urinary system is healthy, the bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.

Circular muscles called sphincters help keep urine from leaking. The sphincter muscles close tightly like a rubber band around the opening of the bladder into the urethra, the tube that allows urine to pass outside the body.

Nerves in the bladder tell you when it is time to urinate, or empty your bladder. As the bladder first fills with urine, you may notice a feeling that you need to urinate. The sensation to urinate becomes stronger as the bladder continues to fill and reaches its limit. At that point, nerves from the bladder send a message to the brain that the bladder is full, and your urge to empty your bladder intensifies.

When you urinate, the brain signals the bladder muscles to tighten, squeezing urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax. As these muscles relax, urine exits the bladder through the urethra. When all the signals occur in the correct order, normal urination occurs.
