Question
1. The fluid-that-will-be-known-as-urine begins its journey with the ??? of blood in/through a structure called the filtration membrane. Fluid exits through holes called fenestrations in the ??? capillaries, trickles through a mesh of biomolecules in the basement membrane, then slips through the slits between "feet" of the ???. The fluid produced here, called ???, is equal to ??? minus its large macromolecules, such as proteins.
Upshot: because of how filtrate is formed, a healthy individual's urine should never contain ???.
Diagnosis: the presence of ??? in the urine is usually a sign of kidney disease or extreme hypertension, while the presence of ??? in the urine usually means the patient has a urinary tract infection underway.
Few of the word bank: filtration; glomerular; podoccytes; plasma; glucose or amino acids; erythrocytes; proteins;leukocytes;
2. Filtrate is then adjusted in the ???, with the ??? (action) of ??? (amount) of nutrients, ??? (amount) of water and electrolytes, ??? (amount) of H+ and ??? (amount) of bicarbonate. At the same time, there is the ??? (action) of nitrogen wastes, drugs and toxins, and acid.
Upshot: given what is removed from the filtrate here, a healthy patient's urine should never contain ???.
Diagnosis: the presence of ??? in the urine is usually taken to be a sign of diabetes mellitus.
Word Bank: N.L (nephron loop); filtration; glucose or amino acid; nearly 100%; about 65%; none; secretion;glucose;protein
Explanation / Answer
The fluid that will be known as urine begins its journey with the filtration of blood in / through a structure called the filtration memberane. Fluid exits through holes called fenestrations in the glomerular capillaries, trickles through a mesh of biomolecules in the basement memberane, then slips through the slits between feet of the podoccytes. The fluid produced here is called glomerular filtrate , is equal to plasma minus its large macromolecules such as proteins.
Upshot: because of how filtrates is formed a healthy individuals urine should never contain erythrocytes.
Diagnosis: the presence of glucose or aminoacids in the urine is usually a sign of kidney disease or extreme hypertension, while the presence of leukocytes in the urine usually means the patient has a urinary tract infection underway.
