Multiple choice bio-chemistry digestion liver functions of the liver secretory organs

The structural and functional units of liver are called

  1. Glisson's capsule

  2. Hepatic cells

  3. Hepatic cords

  4. Hepatic lobules
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. Glisson's capsule: It is a layer of dense connective tissue that surrounds the liver. 
B. Hepatic cells are the cells of liver and building blocks of liver.
C. Hepatic cords are the mass of cells (hepatocytes) which are arranged in irregular rows and columns.
D. Hepatic lobules are the minute, thin, profusely branched septa like trabeculae which extend inwards from the Glisson's capsule and divide each liver lobe into polyhedral units. These are the structural and functional units of liver.
So, the correct answer is 'Hepatic lobules'.

Cells of the liver manufacture

  1. Diastase

  2. Amylase

  3. Lipase

  4. Insulin

  5. None of the above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

The liver doesn't secrete any enzyme. The liver only secretes bile that it produced by the byproducts of haemoglobin breakdown. With the presence of bile, lipase, an enzyme will be able to break down the fat into smaller units.

Kupffer cells of liver are

  1. Loose connective tissue

  2. Phagocytic cell

  3. Mast cell

  4. Fat cell
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Kupffer cells constitute 80-90% of the tissue macrophages present in the body. They are found in the lumen of the liver sinusoids. 

So, the correct answer is 'phagocytic cells '

Kupffer cell of liver are

  1. Loose connective tissue

  2. Phagocytic cell

  3. Mast cell

  4. Fat cell
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Kupffer cells are specialized macrophages located in the liver, lining the walls of sinusoids. Kupffer cells are a part of the mononuclear phagocytic system. The main function of kupffer cells is clearing any bacteria or foreign substances which are harmful to the body. Hence, Kupffer cells of the liver are the phagocytic cell.

So, the correct answer is 'Phagocytic cell'.

Rhabditiform larva of Ascaris undergoes second and third moulting's in?

  1. Liver

  2. Heart

  3. Alveoli of lungs

  4. Small intestine
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

During its lifecycle, the infective juvenile or rhabditiform larva of Ascaris migrates through the bloodstream to the heart and lungs. It undergoes its second and third molts inside the alveoli of the lungs before moving up the trachea.

Cells of liver which act as phagocytes are

  1. Dieters cells

  2. Kupffer cells

  3. Hensen cells

  4. Acinar cells
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Kupffer cells, also known as Browicz-Kupffer cells are specialized macrophages located in the liver lining the walls of the sinusoids that form part of the reticuloendothelial system. Red blood cells are broken down by phagocytic action of Kupffer cells, where the hemoglobin molecule is split. The globin chains are re-utilized, while the iron-containing portion, heme, is further broken down into iron, which is re-utilized, and bilirubin, which is conjugated to glucuronic acid within hepatocytes and secreted into the bile.
