Answer (1)
The digestive system is a series of organs and glands that work together to break down food, absorb nutrients, and eliminate waste. The main parts of the digestive system include:
Mouth : Where digestion begins with chewing and saliva breaking down food.
Esophagus : A tube that connects the mouth to the stomach, transporting food.
Stomach : Produces acids and enzymes to further break down food into a semi-liquid form called chyme.
Small Intestine : Further digests food and absorbs nutrients into the bloodstream.
Liver : Produces bile to help digest fats.
Gallbladder : Stores and concentrates bile from the liver.
Pancreas : Produces digestive enzymes and hormones to assist in digestion.
Large Intestine (Colon) : Absorbs water and forms waste products into stool.
Rectum and Anus : Expel waste from the body.
Let's evaluate each statement to determine if it's true or false:
a) The function of the excretory system is to expel waste from the body. TRUE . The excretory system removes waste and excess substances from the body, including through the kidneys, which filter blood to produce urine.
b) The ureters filter the blood and separate the waste and the water. FALSE . The kidneys, not the ureters, are responsible for filtering blood and separating waste products and excess water to form urine. The ureters are tubes that transport urine from the kidneys to the bladder.
c) The combination of waste and water forms the ureter. FALSE . The combination of waste and water forms urine, not the ureter. The ureters are tubes that carry this urine from the kidneys to the bladder.
d) The urine goes down two tubes called ureters. TRUE . The ureters are indeed the tubes that carry urine from each kidney to the bladder.
e) When the kidney is full, your body tells you to go to the bathroom. FALSE . It's actually when the bladder becomes full of urine that signals are sent to the brain to go to the bathroom.
