Seminal plasma in human male is rich in?
Fructose and calcium.
What protection of the sperm against bacteria is the function of?
The protection of sperm against bacteria is primarily the function of the seminal plasma, which is the fluid that makes up most of the ejaculate. The seminal plasma contains antibacterial substances such as enzymes, antimicrobial peptides, and immunoglobulins, which help to inhibit the growth and activity of bacteria. Additionally, the acidic pH of the vagina also provides a natural barrier against bacterial infections.
Name all structures contributing to its formation and describe the composition of semen?
Composition of human semen: The components of semen come from two sources: sperm, and "seminal plasma". Seminal plasma, in turn, is produced by contributions from the seminal vesicle, prostate, and bulbourethral glands. Seminal plasma of humans contains a complex range of organic and inorganic constituents. The seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract. The normal environment of the vagina is a hostile one for sperm cells, as it is very acidic (from the native microflora producing lactic acid), viscous, and patrolled by immune cells. The components in the seminal plasma attempt to compensate for this hostile environment. Basic amines such as putrescine, spermine, spermidine and cadaverine are responsible for the smell and flavor of semen. These alkaline bases counteract the acidic environment of the vaginal canal, and protect DNA inside the sperm from acidic denaturation. The components and contributions of semen are as follows: Testes: 2-5%. Approximately 200- to 500-million spermatozoa (also called sperm or spermatozoans), produced in the testes, are released per ejaculation. Seminal vesicle: 65-75% amino acids, citrate, enzymes, flavins, fructose (the main energy source of sperm cells, which rely entirely on sugars from the seminal plasma for energy), phosphorylcholine, prostaglandins (involved in suppressing an immune response by the female against the foreign semen), proteins, vitamin C Prostate: 25-30% acid phosphatase, citric acid, fibrinolysin, prostate specific antigen, proteolytic enzymes, zinc (serves to help to stabilize the DNA-containing chromatin in the sperm cells. A zinc deficiency may result in lowered fertility because of increased sperm fragility. Zinc deficiency can also adversely affect spermatogenesis.) Bulbourethral glands < 1% galactose, mucus (serve to increase the mobility of sperm cells in the vagina and cervix by creating a less viscous channel for the sperm cells to swim through, and preventing their diffusion out of the semen. Contributes to the cohesive jelly-like texture of semen.), pre-ejaculate, sialic acid A 1992 World Health Organization report described normal human semen as having a volume of 2 ml or greater, pH of 7.2 to 8.0, sperm concentration of 20x106 spermatozoa/ml or more, sperm count of 40x106 spermatozoa per ejaculate or more and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid progression (category a) within 60 minutes of ejaculation.
What is seminal plasma?
Seminalplasmin is a component of male seminal fluid. It acts as an antibiotic which has the capability of destroying certain bacteria. Because the female reproductive tract and the semen contain bacteria, the seminalplasmin helps to keep these bacteria under control; and thus helps protect the sperm and ensure fertilization which will lead eventually to reproduction. Please see the related link for more information.
What glands store secretions until the cells rupture?
the Holocrine gland the secretion is released by the disruption of the plasma membrane and destruction of the cell
What makes the liquid part of semen?
Sperm and secretions from the prostate gland, bulbourethral glands, and seminal vesicles.
Seminal plasma in human male is rich in?
Fructose and calcium.
What adds a chemical fluid to the semen?
The seminal vesicle adds a sugary rich and nutritious fluid to the sperm.

What is semen made out of?
Composition of human semenDuring the process of ejaculation, sperm passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen. The seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen.[1] The prostatic secretion, influenced by dihydrotestosterone, is a whitish (sometimes clear), thin fluid containing proteolytic enzymes, citric acid, acid phosphatase and lipids.[1] The bulbourethral glands secrete a clear secretion into the lumen of the urethra to lubricate it.[2] Sertoli cells, which nurture and support developing spermatocytes, secrete a fluid into seminiferous tubules that helps transport sperm to the genital ducts. The ductuli efferentes possess cuboidal cells with microvilli and lysosomal granules that modify the semen by reabsorbing some fluid. Once the semen enters the ductus epididymis the principle cells, which contain pinocytotic vessels indicating fluid reabsorption, secrete glycerophosphocholine which most likely inhibits premature capacitation. The accessory genital ducts, the seminal vesicle, prostate glands, and the bulbourethral glands, produce most of the seminal fluid.Seminal plasma of humans contains a complex range of organic and inorganic constituents.The seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract.

The Cowper's glands add a clear fluid.

Does the adrenal contribute to the urinary system?
The adrenal glands affect kidney function through the secretion of aldosterone, a hormone involved in regulating theosmolarity of blood plasma. Also, when adrenalin is secreted it shuts down blood flow to the urinary and digestive systems making them work slowly and produce less waste.
What is the combination of plasma and formed elements called?
It is called whole blood. Whole Blood is Plasma & Formed Elements (RBC's, WBC's, etc) Plasma contributes 46-63% and the Formed Elements contribute 37-54% of whole blood in the body.
