  2. Gynochorism

  3. Feminization

  4. Gynaecomastia

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gynaecomastia refers to the presence of enlarged mammary glands in males like that of females and is caused by the presence of extra X chromosome in males. Gonochorism is the unisexual condition. Feminization refers to the development of female secondary sexual characters caused by hormonal changes at puberty in females. So, the correct answer is option D.

"4s gland" is 

  1. Pancreas

  2. Liver

  3. Thyroid

  4. Adrenal

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The adrenal gland is known as 4S gland. 4S stands for the source of energy, sugar metabolism, salt retention and sex hormones. 

The adrenal glands, located at the top of each kidney, produce hormones that help the body control blood sugar, burn protein, and fat, react to stressors like a major illness or injury and regulate blood pressure. Two of the most important adrenal hormones are cortisol and aldosterone.

The liver is ........ gland in the body. 

  1. Tallest

  2. Smallest

  3. Largest

  4. Thickest

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The liver is the largest glandular organ in the body and performs multiple critical functions to keep the body pure of toxins and harmful substances. An average adult liver weighs about three pounds. Located in the upper-right portion of the abdominal cavity under the diaphragm and to the right of the stomach, the liver consists of four lobes. It receives about 1.5 quarts of blood every minute via the hepatic artery and portal vein. 

Therefore, the correct answer is option C.

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'.

.......... is the largest gland in the body.

  1. Spleen

  2. Thymus

  3. Liver

  4. Pancreas

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Liver is the largest gland in the body. It is a digestive gland present at the left half of the digestive system besides stomach. It synthesises bile, which emulsify (breaking into small droplets) fats and increase the surface area for the action of lipase enzyme.

Therefore, the correct answer is option C.

Which gland is not associated with human alimentary canal?

  1. Salivary gland

  2. Adrenal gland

  3. Liver

  4. Pancreas

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Human alimentary canal or gastrointestinal tract associates wit salivary glands, liver, pancreas, small intestine etc. The adrenal glands are endocrine glands that produce a wide variety of hormones. They are found above the kidneys and consist of a number of different layers that directly influence the structure and function of the glands. It is not associated with alimentary canal. Thus, option B is correct.

Largest digestive gland in the human body is

  1. Liver

  2. Pancreas

  3. Gall bladder

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The digestive glands associated with the alimentary canal include the salivary glands, the liver and the pancreas. Liver is the largest gland of the body weighing about 1.2 to 1.5 kg in an adult human. It is situated in the abdominal cavity, just below the diaphragm and has two lobes. The hepatic lobules are the structural and functional units of liver containing hepatic cells arranged in the form of cords. Each lobule is covered by a thin connective tissue sheath called the Glissons capsule. The bile secreted by the hepatic cells passes through the hepatic ducts and is stored and concentrated in a thin muscular sac, called the gall bladder. The duct of gall bladder (cystic duct) along with the hepatic duct from the liver forms the common bile duct.
