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

Liver is called the reticular gland because

  1. The shape is reticular

  2. It contains reticular tissue

  3. Lobules branches and anastomose with one another to form a network

  4. Hepatic duct and cystic duct unite to form the bile duct
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • The liver is an organ that is present on the right side of the stomach.
  • Liver tissue is made up of lots of smaller units of liver cells called lobules. Many canals carrying blood and bile run between the liver cells. 
  •  Reticular fibre is a type of fibre in connective tissue. It is composed of type III collagen secreted by reticular cells. Reticular fibres crosslink to form a fine meshwork(reticulin). 
  • This network acts as a supporting mesh in soft tissue such as liver, bone marrow and the tissues and organs of the lymphatic system. Hence, the Liver is called the reticular gland because it contains reticular tissue.
So, the correct answer is 'It contains reticular tissue'.

  1. Ovary

  2. Adrenal

  3. Liver

  4. Kidney

C Correct answer
Explanation

A. The ovaries are solid organs and are composed of connective tissue, the stroma. The stroma consists of an outer ovarian cortex and central ovarian medulla.

B. Adrenal: The adrenals are conical, yellowish bodies. Each has two distinct regions are called adrenal cortex and adrenal medulla.
D. Kidney:  The two regions of the kidney are outer region is called renal cortex and inner region is termed renal medulla.

So, the correct answer is 'Liver'.

How many lobes of liver are present in rabbit?

  1. 2

  2. 4

  3. 5

  4. 6
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The rabbit liver is situated in the epigastric region, between both costal arches, reaching the level of the right 7th and left 9th ribs. Rabit liver is divided into two right and left the region by deep cleft with right and left lobes. These lobes are further divided into the posterior and anterior region. It contains five lobes, as the right hepatic lobe, caudate and quadrate lobes are single, and the left hepatic one is separated in lateral and medial parts. Thus the correct answer is option C.

Sinusoids are characterised by

  1. Irregular lumen

  2. Absence of endothelium

  3. Mixing of blood and lymph

  4. Both B and C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sinusoids are characterized by a form of terminal blood channel consisting of a large, irregular anastomosing vessel having a lining of reticulo-endothelium and found in the liver, heart, spleen, pancreas, and the adrenal, parathyroid, carotid, and hemolymph glands.

So, the correct option is 'Irregular lumen'.

Which of the following stimulates the secretion of gastric juice?

  1. Gastrin

  2. Enterogastrone

  3. Secretin

  4. Hepatocrinin
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gastrin is a peptide hormone, that stimulates secretion of gastric acid ($HCl$) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum and the pancreas.
