Parts And Functions Of Excretory System! Trivia Quiz

The explanation for the given answer is that the skin does indeed secrete a fluid called sweat through the sweat glands located in the dermis. Sweat is primarily composed of water, but it also contains small amounts of metabolic waste such as urea and salt. This waste is excreted through the sweat glands as part of the body's natural cooling mechanism and to maintain electrolyte balance. Therefore, the statement is true.

The main function of the Excretory System is to get rid of waste products from your cells. This system is responsible for filtering and eliminating metabolic waste, such as urea and excess salts, from the body. It helps maintain the balance of fluids and electrolytes, regulates blood pressure, and removes toxins from the bloodstream. Additionally, the excretory system plays a crucial role in maintaining homeostasis by controlling the concentration of various substances in the body, such as water, ions, and pH levels.

Urine flows from the kidney to the bladder. The kidneys filter waste products and excess water from the blood to produce urine. The urine then travels through tubes called ureters from the kidneys to the bladder. The bladder acts as a storage organ for urine until it is expelled from the body through the urethra.

Sweat is primarily composed of water and minerals that the body does not need. When the body gets overheated, it produces sweat as a way to cool down. Sweat helps regulate body temperature by evaporating from the skin's surface. In addition to water, sweat also contains small amounts of minerals like sodium, potassium, and chloride. These minerals are excreted through sweat, helping to maintain the body's electrolyte balance. However, the body does not require excessive amounts of these minerals, which is why they are considered as substances that the body does not need.

The statement is true because each kidney contains over 1 million nephrons, which are responsible for filtering waste products from the blood and producing urine. Nephrons are tiny structures that play a crucial role in maintaining the body's fluid balance and removing toxins. They filter the blood by selectively reabsorbing essential substances and excreting waste products. Therefore, the statement accurately describes the function and quantity of nephrons in each kidney.

The heart is not an organ of the excretory system because its main function is to pump blood throughout the body, not to excrete waste products. The liver, kidneys, and skin, on the other hand, are all organs that play a role in the excretion of waste materials from the body. The liver helps in the breakdown and removal of toxins, the kidneys filter waste products from the blood to produce urine, and the skin eliminates waste through sweat.

Extra water and salts can be considered as waste products because they are substances that are not needed or utilized by the body. When the body has enough water and salts to function properly, any excess amounts are excreted through urine or sweat. Therefore, extra water and salts can be classified as waste products that the body eliminates to maintain balance and homeostasis.

The nephrons are responsible for filtering the blood in the body. They are small structures located in the kidneys and play a crucial role in removing waste products, excess water, and toxins from the bloodstream. The ureters are tubes that transport urine from the kidneys to the bladder, while the intestines are involved in the digestion and absorption of nutrients. Therefore, the correct answer is nephrons, as they specifically perform the function of filtering the blood.

The kidney's primary function is to eliminate waste from the bloodstream by producing urine. This process involves filtering the blood and removing waste products, excess water, and other substances that are not needed by the body. The urine is then transported to the bladder and eventually expelled from the body.

The urine is stored in the bladder before it is pushed out of the body. The bladder is a muscular organ located in the pelvis and its main function is to collect and store urine produced by the kidneys. When the bladder becomes full, it sends signals to the brain indicating the need to urinate. The urine is then expelled from the body through the urethra, a tube that connects the bladder to the outside of the body.

The skin takes part in excretion when a person sweats. Sweating is the body's way of regulating temperature and eliminating waste products such as water, salt, and urea. Sweat glands in the skin produce sweat, which is then released through the pores. This process helps to remove toxins and maintain the body's balance of fluids and electrolytes. Therefore, when a person sweats, the skin actively participates in the excretory function of the body.

The correct answer is glomerus. The glomerus is a cluster of capillaries located in the kidney. It is responsible for filtering waste products from the blood and forming urine. The glomerus plays a crucial role in the process of urine formation and is an essential component of the nephron, the functional unit of the kidney.

The kidneys are located near the middle of the back, on either side of the spine. This is the correct answer because the kidneys are retroperitoneal organs, meaning they are located behind the peritoneum (the membrane that lines the abdominal cavity). They are positioned in the back, just below the ribcage, and are situated on either side of the spine.

The urethra is the tube that carries urine from the bladder to the outside of the body. It serves as a passage for urine to exit the body during urination. The ureter, on the other hand, carries urine from the kidneys to the bladder, while the distal tubule and loop of Henle are parts of the kidney's nephron structure involved in the filtration and reabsorption of substances.

Sweating helps the human body by cooling it down. When we sweat, the moisture on our skin evaporates, which takes away heat from our body. This evaporation process helps to lower our body temperature and prevent overheating. Therefore, sweating is a natural cooling mechanism that helps regulate our body temperature and keep us comfortable in hot conditions or during physical activity.

The urethra is the tube that carries urine from the bladder to the outside of the body. It is responsible for the elimination of urine from the body. The ureter, on the other hand, is a tube that carries urine from the kidneys to the bladder, while the nephron is the functional unit of the kidney responsible for filtering blood and producing urine. Therefore, the correct answer is urethra.

The proximal and distal tubule are separated by the loop of Henle. The loop of Henle is a U-shaped structure in the nephron of the kidney that plays a crucial role in the reabsorption of water and electrolytes. It is located between the proximal and distal tubules and helps to establish a concentration gradient in the kidney, allowing for the reabsorption of water and the excretion of waste products.

After blood enters the kidney, it travels to the glomerulus. The glomerulus is a network of tiny blood vessels called capillaries that are responsible for filtering waste products and excess fluid from the blood. The blood is forced through the capillaries under high pressure, allowing small molecules such as water, salts, and waste products to pass through into the surrounding structures, while larger molecules like proteins and blood cells are retained in the blood. This initial filtration process in the glomerulus is the first step in the formation of urine in the kidneys.

The kidneys perform several important functions in the body, including regulating blood pressure, removing waste products, and maintaining the balance of water and electrolytes. One of the key functions of the kidneys is to secrete hormones, such as erythropoietin and renin, which play a role in red blood cell production and blood pressure regulation, respectively. Therefore, secrete hormones is not a correct answer as it contradicts the actual function of the kidneys.

The "A" arrow points to the adrenal gland. The adrenal gland is an endocrine gland located on top of the kidneys. It is responsible for producing hormones such as adrenaline, which helps the body respond to stress, and cortisol, which regulates metabolism and immune response.

The process of digestion does not release air into the bloodstream. While excess nutrients, salts, minerals, water, drugs, and toxins can enter the bloodstream through the digestive system, air does not.

The structure labeled "G" is the proximal tubule. This is because the proximal tubule is a part of the nephron in the kidney, responsible for reabsorbing water, ions, and nutrients from the filtrate. It is located after the glomerulus and Bowman's capsule, which are responsible for filtration, and before the distal tubule, which is responsible for further modification and reabsorption.

The structure labeled "B" is the Bowman's capsule. This is a cup-shaped structure in the kidney that surrounds the glomerulus. Its main function is to collect the filtrate produced by the glomerulus and pass it on to the renal tubules for further processing. The Bowman's capsule plays a crucial role in the filtration process of the nephron, which is the functional unit of the kidney.

The excretory system is a passive biological system that removes excess, necessary or dangerous materials from an organism, helping to maintain homeostasis and prevent damage to the body. It plays a crucial role in eliminating metabolic waste and maintaining internal environmental balance within the organism.

The renal pelvis is the correct answer because it is the part of the kidney where urine is initially stored before it moves to the bladder. The renal pelvis collects urine from the kidney's collecting ducts and funnels it into the ureter, which then transports the urine to the bladder for storage until it is expelled from the body. The medulla and loop of Henle are important structures within the kidney, but they are not directly involved in the storage of urine.

The correct answer is "Maintain volume of extracellular fluid." This function refers to the role of the kidneys in regulating the balance of fluids in the body. The kidneys help to maintain the proper volume of extracellular fluid by filtering waste products and excess water from the blood, and then reabsorbing the necessary substances back into the bloodstream. This process helps to regulate blood pressure, electrolyte balance, and pH levels in the body.

The arrow "B" points to the cortex. The cortex is the outer layer of the kidney, which contains the glomeruli and the convoluted tubules. It is responsible for filtering the blood and producing urine.

The liver is responsible for filtering wastes from the blood. It plays a crucial role in detoxification by removing harmful substances, metabolizing drugs, and breaking down waste products. The liver filters the blood before it circulates to the rest of the body, ensuring that toxins and waste are removed from the bloodstream. Without the liver's filtration process, toxins would accumulate in the body and lead to various health issues.

The question is asking about the structures that arise from the medial aspect of each kidney before descending towards the front of the psoas major muscle. The correct answer is "ureters, renal pelvis, bladder, psoas major." The ureters are tubes that carry urine from the kidneys to the bladder. The renal pelvis is the funnel-shaped area in the kidney that collects urine before it enters the ureters. The bladder is the organ that stores urine. The psoas major is a muscle located in the lower back.
