Question

Secretions from which one of the following are rich in fructose, calcium, and some enzymes?
A. Salivary glands
B. Male accessory glands
C. Liver
D. Pancreas

Answer 1

Secretions are the substances that are released by the various kinds of glands in our body. Secretions are hormonal and enzymes usually. Moreover, secretions from a particular endocrine gland are rich in fructose, calcium, and enzymes.

Complete answer: Let us look at all the options that are given to us one by one.
-Salivary glands are the saliva-producing glands. These glands are present inside the mouth. Humans have three pairs of salivary glands. These are exocrine glands. The saliva is made up of ninety percent water. It has some percent of NaCl and KCl also. Apart from that, it contains the mucin protein, thiocyanate ions, and IgA antibodies. Saliva also consists of two enzymes, lysozyme, and ptyalin. The pH of the saliva is 6.5 making it slightly acidic.
-Male accessory glands: There are three pairs of male accessory glands. Their secretions are often termed as the seminal fluid. The seminal fluid consists of fructose, citric acid, prostaglandins, and inositol from the seminal vesicles. The prostate secretes alkaline substances like citrate ions, calcium, phosphate ions, and profibrinolysin in the seminal fluid. A viscous mucus is secreted from the cowper’s glands that act as the lubricant.
-Liver: The secretion of the liver is known as the bile juice. The bile juice consists of ninety percent water. Apart from that, it contains lecithin, cholesterol, sodium or potassium taurocholate, and glycocholate. Bile juice contains no enzymes.
-Pancreas: The pancreas is a mixed gland. It consists of both the endocrine and the exocrine parts. The cells secreting various secretions are known as the Islet of the Langerhans. These cells secrete various types of hormones like glucagon, insulin, etc. Also, pancreatic juice and hormone are produced. Pancreatic juice contains several enzymes.
Thus, based on the above information we can conclude that secretions from the male accessory glands are rich in fructose, calcium, and some enzymes.
Hence, the correct answer is option (B).

Note: The male accessory glands are as follows –
a. Seminal vesicles – They are paired, tubular, and coiled glands situated behind the urinary bladder. They secrete the seminal fluid which is viscous in nature. It is the main component of semen.
b. Prostate gland – It is a chestnut-shaped gland found at the base of the urinary bladder and at the starting of the urethra. It gives an alkaline nature to the semen. It also gives a characteristic odor to the seminal fluid.
c. Cowper’s gland – They are also known as the bulbourethral glands. They are the pea-sized structures lying adjacent to the urethra that are present at the base of the penis.
