1. A glomerulus is

A.

the expanded end of a nephron.

B.

a knot of capillaries within the renal corpuscle.

C.

the source of erythropoietin.

D.

attached to the collecting duct.

E.

the horseshoe-shaped segment of the nephron.

2. Each of the following organs is part of the urinary system except the

A.

kidney.

B.

urinary bladder.

C.

rectum.

D.

ureter.

E.

urethra.

 

3. The urinary system does all of the following except

A.

excreting excess protein molecules.

B.

regulating blood volume.

4. Case Study 5: Shane is a 76 year old male who was admitted to the emergency department after his daughter found him very confused and barely conscious. The initial observations made by paramedics included a rapid breathing rate, a high temperature, sunken eyes and dry mouth & skin. Shane has also been ill for several days with the flu. Upon admission the doctors begin to suspect Shane’s symptoms are due to a hyperglycaemic attack (high blood sugar levels) and further testing diagnoses Shane with Diabetes. Pancreas is the main organ responsible for the production of hormones, such as insulin (lowerblood glucose) and glucagon (increase blood glucose).


Question: What does it mean to say that the pancreas is both an endocrine and an exocrine organ?

 

A.

The endocrine cells secrete at their basal surfaces into the interstitial space, exactly opposite to the exocrine gland cells, which secrete fluid and digestive enzymes out of their surfaces into tiny ducts.

B.

The endocrine and exocrine cells  both secrete via without duct onto the organ, body cavity or tissue surfaces. 

C.

None of the above statements are correct. 

D.

The endocrine and exocrine cells both secrete via tiny ducts onto the organ, body cavity or tissue surfaces. 

E.

The endocrine cells secrete  fluid and digestive enzymes out of their surfaces into tiny ducts, exactly opposite to the exocrine gland cells, which secrete at their basal surfaces into the interstitial space.
