In the analogy where the liver is like the sewage treatment plant, the kidneys are like the trucks that take the waste out of town. the people who produce the waste. trash cans where the waste is stored. the trucks that carry the waste from the people who produce it to the treatment plant.
Which comes first the reabsorption of salt or water in the kidneys?
The reabsorption of water in the kidneys always precedes the reabsorption of salt. F *The reabsorption of salt in the kidneys always precedes the reabsorption of water. Section: 11.04 Which substances regulate the reabsorption of sodium and water in the distal convoluted tubule?
Is a nephron a two-way system?
A nephron is a two-way system with glomerular filtrate traveling back and forth within the nephron. false Place the parts of the nephron in order.
How do the kidneys interact with other organ systems to maintain homeostasis?
The blood carries these to the kidneys where they are eliminated. Sometimes, urea can be excreted by the sweat glands in perspiration. Section: 11.04 The kidneys interact with every other organ system of the human body in maintaining homeostasis.
What do the kidneys filter and excrete from the blood?
The kidneys filter and excrete H+ from the blood. *The kidneys remove and excrete excess H+ from the blood in order to maintain a blood pH of 7.4. Section: 11.04 Which of the following is not a metabolic waste product? erythropoietin *Erythropoietin is a hormone secreted by the kidneys. Section: 11.01
Which of the following best describes the location of the kidneys?
The kidneys are located at the rear wall of the abdominal cavity just above the waistline and are protected by the ribcage. They are considered retroperitoneal, which means that they lie behind the peritoneum.
Why is the refrigerator cleaning Example A good analogy of how the kidneys work?
When nephrons clean up the blood, it's like cleaning a fridge – everything (all the substances apart from blood cells and proteins) has to come out of the fridge, so the inside of the fridge can be cleaned. Then the substances that are still in date and useful are put back into the fridge.
Which of the following parts of the kidney is actually an expansion of the upper end of the ureter?
renal pelvis, enlarged upper end of the ureter, the tube through which urine flows from the kidney to the urinary bladder.
Why do water and small molecules move from the glomerulus into the filtrate within the kidney tubules?
Why do water and small molecules move from the glomerulus into the filtrate? *Due to glomerular blood pressure, water and small molecules move from the glomerulus to the inside of the glomerular capsule as part of the filtrate.
How do the kidneys assist the body in maintaining homeostasis in terms of fluid levels and hydration?
The kidneys control the amount of water, ions, and other substances in the blood by excreting more or less of them in urine. The kidneys also secrete hormones that help maintain homeostasis.
What is an analogy for the urinary system?
The urethra is like a garbage truck because its job is to dispose of waste. A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.
Which structure is included in the discussion of the urinary system even though it is part of the circulatory system?
CQLC APII Urinary SystemQuestionAnswereven though this structure is part of the circulatory system, it is included in the discussion of the urinary system.glomeruluswhat are the functions of the urinary systemremove waste from the blood, maintain proper electrolyte balance, maintain proper pH level in the blood.28 more rows
Which of the following is one of the structures in the renal corpuscle group of answer choices?
Structure. The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule.
Where are the upper and lower borders of the kidneys located?
The upper and lower borders of the kidneys are generally at the levels of the twelfth thoracic and third lumbar vertebrae, respectively. The kidneys are positioned retroperitoneally, which means they are behind the parietal peritoneum and against the deep muscles of the back.
What is the path of an excreted water molecule as it moves from the glomerulus to collecting duct?
What is the path of an excreted water molecule as it moves from the glomerulus to collecting duct? - protein is digested and then concentrated in glomerular (Bowman's) capsule. - the kidney manufactures and then stores protein in the glomerulus. - reabsorption of protein occurs.
In what direction are substances moving during the process of secretion explain what these substances are and why they are excreted from the body?
In what direction are substances moving during the process of secretion? Explain what these substances are and why they are excreted from the body. Substances are being moved from the blood into the nephrons. These substances are waste products, drugs, minerals, potassium and hydrogen ions.
What is the path of fluid as it is filtered from the blood and flows through the nephron?
The correct path of filtrate through a nephron starts in the renal corpuscle, which is comprised of the glomerulus and Bowman's capsule. Filtrate then passes through the proximal convoluted tubule, where the majority of reabsorption takes place.
How do kidneys interact with other organ systems?
*The kidneys play a major role in homeostasis in the body and interact with every other organ system. The reabsorption of water in the kidneys always precedes the reabsorption of salt.
Which parts of the nephron are in order of how filtration would occur?
Place the parts of the nephron in order of how filtration would occur. 1. ascending limb of loop; 2. descending limb of loop; 3. proximal convoluted tubule; 4. glomerulus; 5. collecting duct; 6. distal convoluted tubule
Where is water reabsorbed?
It is reabsorbed at the proximal convoluted tubule. *Nutrients such as glucose and amino acids are reabsorbed at the proximal convoluted tubule. Section: 11.03. Approximately 99% of the water that is filtered in the glomerulus is reabsorbed.
Does caffeine affect the urinary system?
It may affect the ability to sleep but caffeine has very little effect on the urinary system. It can cause a headache if consumed late at night. It can lead to diarrhea. It increases the flow of urine and causes you to go to the bathroom during the night. *Caffeine is a diurectic and increases the flow of urine.
Does glucose go into the glomerular filtrate?
No glucose is filtered into the glomerular filtrate. The kidneys produce glucose in diabetes. The carriers for glucose reabsorption reach their maximum rate of transport. The ascending limb of the loop of Henle secretes glucose into the urine.
