The process by which the body tries to maintain a constant internal environment is called 1)_____________________. Our 2)_______________ ________________ aids this process by removing chemical wastes from the blood and balancing the amounts of needed substances in it. The 3)_______________ is also considered an excretory organ because it rids the body of some of the same wastes that are in urine by excreting them in sweat. 4)__________ is a waste that results from the breakdown of amino acids and is found in both urine and sweat. The primary organs of our excretory system are a pair of 5)_____________ found behind our abdominal cavity. They produce 6)________________ which is taken to its storage place called the 7)_________________ through two tiny muscular tubes known as the 8)____________________. Bowman's capsule
filtrate
filtration
glomerulus
nephrons
reabsorption
tubule
The microscopic functional units in a kidney are called 9)_________________. They consist of a 10)___________________, which is ball of capillaries under a great deal of blood pressure. The process of 11)_____________ occurs here and is a "dumb" process by which particles small enough to fit through the tiny holes in the glomerulus walls go into a collecting cup known as 12)________________ ______________ . From here the liquid known as the 13)____________________ heads down a tiny tube appropriately named the nephron 14)________________ where a very important process occurs. Here, 99% of the water that escaped from the glomerulus is taken back into the blood capillaries by the process of 15)_____________________.ADH
antibiotics
diuresis
H+
loop of Henle
secretion
water
The nephron tubule has a tiny loop that called the 16)________ ___ ___________ where molecules not wanted in the blood are transported into the tubule to be excreted in the urine. This process is called 17)__________________ and is how the body controls pH levels by removing 18)_________ ions and takes toxins from the blood such as 19)______________________ we are prescribed to get rid of infectious bacteria.
The kidneys tubule and its reabsorption rates are controlled by a hormone our pituitary gland (in our head) secretes called 20)_______ or antidiuretic hormone. 21)___________ is production of large amounts of urine. ADH slows this by increasing readsorption of 22)____________ in the tubules of the kidney.
