Within each kidney are millions of microscopic nephrons where filtering takes place. Water, Urea, Glucose and minerals in the blood move into the bowman’s capsule. Wastes that are left after absorption are turned into urine.
How do kidneys clean the blood?
It evaporates, or changes from a liquid to a gas. To make this change heat from the body is used up, resulting in cooling the body.
How is perspiration important to regulating body temperature?
Top Layer: Epidermis
Lower Layer: Dermis
What are the names of the two main layers of skin?
made up of water, urea, and inorganic salts
What is urine
collects urine before it is eliminated from the body through urethra
What job does the bladder perform?
the balance of chemicals and elements in the body
What does the term homeostasis mean?
collect the metabolic waste carbon dioxide
What role do the lungs have in the excretory system?
about the size of a bar of soap. They are located on either side of the spinal cord.
How big are the kidneys and where are they located?
sum of all chemical processes that take place in the cells
metabolism
eliminates metabolic wastes from the body.
excretory system
incredibly small sacks found inside the lungs where the exchange of gases take place.
alveoli
the tiniest blood vessels in the body
Capillaries
two kidney-bean shaped organs responsible for filtering blood
kidneys
a state of balance between the elements of the body
homeostasis
location of true filtering of the blood; millions are found inside each kidney
nephron
waste product made of water, urea, and inorganic salts
urine
tube leading form the kidneys to the bladder
ureter
storage place for the waste products given off by the kidneys
bladder
tube leading form the bladder to outside the body
urethra
organ which performs many roles; stores some digested foods, removes sugar from blood and stores it as glycogen, changes hemoglobin into bile, etc
liver
outermost later of the skin, made from dead skin cells
epidermis
living layer of skin found below epidermis
dermis

it delivers urine from the bladder to the outside world
What is the function of the urethra?
how full the bladder is
what determines when you need to go to go bathroom?
Filter
What word best describes the function of the nephrons?
process by which metabolic wastes are eliminated from the body
What is excretion

What waste compounds are produced by every cell in the body?
excretes water, salts and small amount of urea in sweat
Skin
where carbon dioxide is exhaled
lungs
the liver
What organ converts dangerous nitrogen wastes into urea?
Kidney
What organ removes waste and manages blood ph?
transport urine form the kidneys to the bladder
Ureters
capillaries
Each kidney has nearly a million individual processing units called
glucose
The material that is filtered from the blood contains water, urea, salts, amino acids, some vitamins and
homeostasis
A number of materials, including salts, are removed from the filtrate by _______ and reabsorbed by the capillaries
glomerulus
The ______ is responsible for conserving water and minimizing the volume of filtrate
