What role does the urinary system play in maintaining the human body's homeostasis quizlet?
How does the urinary system help maintain homeostasis? By regulating the body PH, blood pressure and eliminating waste like urea and salt.
What role does the urinary system play?
The urinary system's function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy.
Does the urinary system maintain body temperature?
The urine in the bladder also helps regulate body temperature.
Which two parts of the body's homeostasis is controlled by the urinary tract?
The urinary system maintains an appropriate fluid volume by regulating the amount of water that is excreted in the urine. Other aspects of its function include regulating the concentrations of various electrolytes in the body fluids and maintaining normal pH of the blood.
How does each organ system maintain homeostasis?
the respiratory system helps the body maintain homeostasis because it gives the bloodstream the oxygen it needs. the circulatory system helps the body maintain homeostasis by transporting nutrients. The circulatory system works with the respiratory system to exchange carbon dioxide and oxygen.
What would happen without the urinary system?
The filtration performed by the urinary tract is vital to keep the body healthy. Without this system, your blood would be full of waste products and extra water. This could cause other systems, like the cardiovascular system, to malfunction and cause serious health issues.
How do kidneys help maintain homeostasis quizlet?
The kidneys maintain homeostasis by controlling the amount of water, ions, and other substances in the blood. cup-shaped strucutre of the nephron of a kidney which encloses the glomerulus and which filtration takes place.
How does the formation of urine by the kidneys contribute to homeostasis quizlet?
kidneys reabsorb as much water as possible back into blood to produce highly concentrated urine full of excreted ions and wastes. changes in excretion of water are controlled by antidiuretic hormone (ADH) ADH is produced in the hypothalamus + released by the posterior pituitary gland to help the body retain water.

Vitamin D Synthesis
In order for vitamin D to become active, it must undergo a hydroxylation reaction in the kidney, that is, an –OH group must be added to calcidiol to make calcitriol (1,25-dihydroxycholecalciferol).
Erythropoiesis
EPO is a 193-amino acid protein that stimulates the formation of red blood cells in the bone marrow. The kidney produces 85 percent of circulating EPO; the liver, the remainder.
Blood Pressure Regulation
Due to osmosis, water follows where Na + leads. Much of the water the kidneys recover from the forming urine follows the reabsorption of Na +. ADH stimulation of aquaporin channels allows for regulation of water recovery in the collecting ducts.
Regulation of Osmolarity
Blood pressure and osmolarity are regulated in a similar fashion. Severe hypo-osmolarity can cause problems like lysis (rupture) of blood cells or widespread edema, which is due to a solute imbalance.
Recovery of Electrolytes
Sodium, calcium, and potassium must be closely regulated. The role of Na + and Ca ++ homeostasis has been discussed at length. Failure of K + regulation can have serious consequences on nerve conduction, skeletal muscle function, and most significantly, on cardiac muscle contraction and rhythm.
pH Regulation
Recall that enzymes lose their three-dimensional conformation and, therefore, their function if the pH is too acidic or basic. This loss of conformation may be a consequence of the breaking of hydrogen bonds.
Chapter Review
The effects of failure of parts of the urinary system may range from inconvenient (incontinence) to fatal (loss of filtration and many others). The kidneys catalyze the final reaction in the synthesis of active vitamin D that in turn helps regulate Ca ++. The kidney hormone EPO stimulates erythrocyte development and promotes adequate O 2 transport.
How does the urinary system affect homeostasis?
The urinary system influences homeostasis by regulating the amount (volume) and the makeup (composition) of blood. The makeup of blood is regulated in a couple ways. The kidneys act to filter out metabolic wastes, like urea, that are picked up by the bloodstream. The kidneys prevent the buildup of this waste by removing it from the body.
What is the function of the urinary system?
I hope you aren't too surprised to find that the function of the urinary system is to filter waste out of the blood and produce urine. Within the urinary system the key players are the kidneys (there are two ...
How do hormones affect the body?
Hormones are chemical messengers that circulate in the bloodstream and can interact with specific cells to change their activity. Hormones allow bodywide chemical communication. An organ can produce a hormone and release it into the bloodstream to directly influence cell and organ activity. In our reservoir analogy, the management office is like the hormones, the dam can't open or close itself, the office has to make a decision about how to control the dam. Let's take a look at how some different hormones influence fluid balance and how that directly relates to the urinary system.
Why is urine darker?
When you're sufficiently hydrated, excess fluid is directed to your urine so the volume is higher, and you can see that it's more dilute (meaning that it's a lighter color). When your fluid intake is lower, the body retains water, your urine volume decreases , and the urine is a darker color. But how do the kidneys know whether to keep water or excrete water? In our reservoir example there was a management office that controlled the opening and closing of our dam. In the human body, this control comes in the form of hormones.
What is the name of the tube that carries urine?
The kidneys contain millions of tiny tubes called nephrons where the blood is filtered, the good stuff (like nutrients) is reabsorbed back into the body, waste is secreted, and water can be secreted or reabsorbed depending on conditions within the body. The fluid produced by the nephrons is urine.
Which hormones are produced by the heart that trigger the kidneys to excrete excess sodium?
We also learned about other hormones involved in the urinary system's processes, including aldosterone, which is a hormone that triggers the kidneys to retain sodium and water, and natriuretic peptides, which are hormones produced by the heart that trigger the kidney to excrete excess sodium and water.
What is the fluid produced by the nephrons?
The fluid produced by the nephrons is urine. The urine is collected into two tubes called the ureters that lead to the bladder. The bladder is the storage compartment for the urine. The last part of the urinary system is the urethra, which is a single tube that leads directly from the bladder to the outside of the body.
How does the urinary system maintain homeostasis?
The urinary system maintains homeostasis by removal and restoration of selected amounts of water and solutes. By regulating and maintaining the volume of blood. Waste products from body cells can produce toxic waste and need to be eliminated from the body. These can include carbon dioxide and water as well as the breakdown from proteins which produces ammonia and urea. Also any excess ions such as sodium, chloride, phosphate and sulphate that exceed the body’s requirements must be eliminated via the kidneys in the form of urine. Water any other non toxic solutes that are needed are able to be reabsorbed helping to maintain homeostasis. Sometimes patients have been prescribed Diuretics to help prevent or ease accumulation of fluid in the tissues.
What is the function of the urinary bladder?
The function of the urinary bladder is a storage container temporarily for urine, until it is expelled through the urethra. The elasticity of the bladder is unmatched as it has the ability to increase in size to make room for increases in urine volume from 600 to 800 ml at maximum capacity. The reason for this elasticity is due to the visceral muscles and transitional epithelium located in the walls of this hollow organ, that allows this distensibility
What organs are responsible for removing fluid from the bloodstream?
Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra. Urine is used to extract excess minerals or vitamins as well as blood corpuscles from the body. The Urinary organs include the kidneys , ureters, bladder, and urethra . The Urinary system works with
What is homeostasis in the nervous system?
Homeostasis is a state where the internal conditions of the body are all balanced out. An example of homeostasis is in one of our readings, the nervous system helps maintain our body’s natural environment with our nervous tissues, the brain, and the spinal cord, these help control the balance in your body. Another example is the endocrine system, this system helps by releasing hormones that regulate your internal balance “such as water and blood sugar” (11/14 agenda “Homeostasis). It is important
Why is the endocrine system important?
Lauryn Varga 03-17-17 1B The Endocrine System is important because it maintains homeostasis. It secretes hormones into the bloodstream which helps the body in growth and reproduction. The endocrine system maintains homeostasis by releasing hormones which affect how the body works and functions. Homeostasis is maintaining the body’s natural state and keeping hormonal levels constant and stable. The endocrine system is a group of glands including the pituitary, thyroid, parathyroid, thymus, testes
What is the endocrine system?
The endocrine system is made up of cells and glands that make hormones and release them into the blood. These hormones help to regulate reproduction, sleep, metabolism, cell growth, and development. The word endocrine is a derivative from two Greek words: “endo”, which means within or inside, and “krinis”, which is a verb for secrete. In the endocrine system, there are different glands that each excrete different hormones. All of these glands are ductless, and secrete their hormones straight into
Why does the urinary system maintain the proper balance of water and H2O?
Because of it's interaction with the bloodstream and it's ability to excrete substance from the body the urinary system maintains the bodies proper balance of water H2O and chemicals.
What is the role of kidneys in the body?
Kidneys play and important role in maintaining the correct pH range with in the body, making sure that we're not become too Acidic or too Alkaline.
What is the final stage of urine production?
SECRETION- The final stage of urine production occurs when the special cell of the renal tubules secrete ammonia, uric acid, and other waste substance directly into the renal tubule. Urine formation is now finished; it passes into the collecting tubules, renal pappila, calyx, renal pelvis, and ultimately into the ureter.
Why is urine acidic?
Normal urine is acidic because this is one way our bodies dispose of excess acids.
What is the name of the protein that should remain in the blood?
Glucose, blood, or ALBUMIN, a protein that should remain in the blood.
Is urine sterile in the bladder?
Urine is sterile only while collecting in the bladder. However, as it passes through urethra in my become contaminated by bacteria.
How do kidneys regulate blood pressure?
The kidneys work with the adrenal cortex, lungs, and liver in the renin–angiotensin–aldosterone system to regulate blood pressure. They regulate osmolarity of the blood by regulating both solutes and water.
Which organs are involved in the renin–angiotensin–aldosterone system?
The kidneys cooperate with the lungs, liver, and adrenal cortex through the renin–angiotensin–aldosterone system (see [link] ). The liver synthesizes and secretes the inactive precursor angiotensinogen. When the blood pressure is low, the kidney synthesizes and releases renin. Renin converts angiotensinogen into angiotensin I, ...
What happens to the kidneys when Na+ is absorbed?
Due to osmosis, water follows where Na + leads. Much of the water the kidneys recover from the forming urine follows the reabsorption of Na +. ADH stimulation of aquaporin channels allows for regulation of water recovery in the collecting ducts. Normally, all of the glucose is recovered, but loss of glucose control (diabetes mellitus) may result in an osmotic dieresis severe enough to produce severe dehydration and death. A loss of renal function means a loss of effective vascular volume control, leading to hypotension (low blood pressure) or hypertension (high blood pressure), which can lead to stroke, heart attack, and aneurysm formation.
Why do kidneys produce more EPO?
If you start an aerobic exercise program, your tissues will need more oxygen to cope, and the kidney will respond with more EPO. If erythrocytes are lost due to severe or prolonged bleeding, or under produced due to disease or severe malnutrition, the kidneys come to the rescue by producing more EPO.
Which organ produces 85 percent of circulating EPO?
The kidney produces 85 percent of circulating EPO; the liver, the remainder. If you move to a higher altitude, the partial pressure of oxygen is lower, meaning there is less pressure to push oxygen across the alveolar membrane and into the red blood cell.
