LEVEL 1
Structural and functional unit of the kidney
Nephron
The major excretory products are - Carbon dioxide, ...........and ............ like ammonia, urea, uric acid, etc.
excess water, nitrogenous compounds
.............. involves forcing out liquid part of the blood into the cavity of Bowman’s capsule.
ultrafiltration/glomerulus filtration
Nitrogenous waste that is excreted as urine by terrestial animals
Urea
Deamination is the process whereby excess ....... and ............ are broken down in the liver to form .........
Protein, amino acids, ammonia
Is highly coiled tubule that extends from Bowman’s capsule to the descending loop of Henle.
Proximal convulated tubule
This waste is a by-product of respiration of both plants and animals.
Carbon dioxide
The skin has ..... which excrete excess water, minerals salts, and traces of urea.
sweat glands
The urinary system has a large ......, and narrow ......, which allows buildup of pressure, thus facilitating .......
afferent arteriole, efferent arteriole, ultra filtration
........ is not excretion, because it involves the removal of undigested food materials from the body which are not metabolic wastes.
defecation / egestion
Urinary system is a system concerned with ...., ...... and ..... of urine.
production, storage, removal
Due to the high pressure in the glomerulus the liquid part of the blood and dissolved substances of small molecular sizes such as urea, glucose, amino acids, salts, uric acid, vitamins, and hormones are forced out of the ......... into the ...........
glomerulus, Bowman’s capsule
Is the production and release of useful material in the body of an organism.
Secretion
The layers are: ........., which contains billions of glomeruli where blood is filtered. The ........which is the space inside the kidney which collects the urine and leads it to the ureter, and the .......... consists of billions of loops of Henle where the amount of salt and water are controlled.
Cortex, pelvis, medulla
Tthe concentration of protein and blood cells in glomerular filtrate and urine is zero because the walls of the ....... of the glomerulus and Bowman’s capsule have very small pores, hence protein and blood cells are not filtered due to their large ........ size
capillaries, molecule/molecular
