The only purpose of kidney is to filter blood. is the statement true or false?

Learning Objectives By the end of this section, you will have completed the following objectives: • Explain how the kidneys serve as the main osmoregulatory organs in mammalian systems • Describe the structure of the kidneys and the functions of the parts of the kidney • Describe how the nephron is the functional unit of the kidney and explain how it actively filters blood and generates urine • Detail the three steps in the formation of urine: glomerular filtration, tubular reabsorption, and tubular secretion Although the kidneys are the major osmoregulatory organ, the skin and lungs also play a role in the process. Water and electrolytes are lost through sweat glands in the skin, which helps moisturize and cool the skin surface, while the lungs expel a small amount of water in the form of mucous secretions and via evaporation of water vapor. Kidneys: The Main Osmoregulatory Organ Figure 1. Kidneys filter the blood, producing urine that is stored in the bladder prior to elimination through the urethra. (credit: modification of work by NCI) The kidneys, illustrated in Figure 1, are a pair of bean-shaped structures that are located just below and posterior to the liver in the peritoneal cavity. The adrenal glands sit on top of each kidney and are also called the suprarenal glands. Kidneys filter blood and purify it. All the blood in the human body is filtered many times a day by the kidneys; these organs use up almost 25 percent of the oxygen absorbed through the lungs to pe...

The Kidneys The kidneys are a pair of bean-shaped organs just above the waist. They are important organs with many functions in the body, including producing A cross-section of a kidney is shown in Figure Urine is the liquid waste product of the body that is excreted by the urinary system. Wastes in the blood come from the normal breakdown of tissues, such as muscles, and from food. The body uses food for energy. After the body has taken the nutrients it needs from food, some of the wastes are absorbed into the blood. If the kidneys did not remove them, these wastes would build up in the blood and damage the body. Kidneys and Nephrons The actual removal of wastes from the blood occurs in tiny units inside the kidneys called nephrons. Nephrons are the structural and functional units of the kidneys. A single kidney may have more than a million nephrons! This is further discussed in the Urinary Systemconcept. Each kidney is supplied by a renal artery and renal vein. Kidneys and Homeostasis The kidneys play many vital roles in homeostasis. They work with many other organ systems to do this. For example, they work with the circulatory system to filter blood, and with the urinary system to remove wastes. The kidneys filter all the blood in the body many times each day and produce a total of about 1.5 liters of urine. The kidneys control the amount of hormones that help maintain homeostasis. Erythropoietin, for example, is a kidney hormone that stimulates bone marrow to produce r...

Q: The only purpose of the kidneys is to filter blood. True or False? A: False. The kidneys are a pair of bean-shaped organs, located just below the ribcage on either side of the spine. They help filter your blood by removing waste and excess fluids, but they do much more. The kidneys help maintain the balance of Q: Urine is made in the kidneys. True or False? A: True. Each day, the kidneys filter up to 150 quarts of blood and produce 1 to 2 quarts of urine, which is composed of body wastes and extra water. The urine passes from the kidneys through tubes called ureters, into the bladder where it is stored until it is filled. When the bladder reaches capacity, signals are sent to the brain that it is time to urinate, and the urine is released out of the body through a tube called the urethra. Q: What are common non-specific symptoms of chronic kidney disease? A: Kidney disease can have many different signs and symptoms that are non-specific, meaning, these same symptoms could also be signs of dysfunction in another body organ. Some non-specific symptoms of renal disease include: - Fatigue - Weakness - Difficulty concentrating - Trouble sleeping - Dry, itchy skin - Frequent urge to urinate - Blood in the urine - Urine is foamy - Puffiness around the eyes - Loss of appetite - Swelling in the ankles and feet - Q: Which kidney disease is known to be inherited? A: Polycystic kidney disease. A type of kidney disease that is genetic, or inherited, is polycystic kidney disease (PKD...
