What three structures, in order, are involved of the production of mature sperm?
34kurt

Answer:

The three anatomical structures that, in order, contribute to the production of mature sperm are the epididymis, seminal vesicle and prostate.

Explanation:

The sperm and the first seminal fluid are produced and found initially in the seminiferous tubules of each testicle. From there they move on to several structures that contribute to the maturation process:

  1. Each <u>seminiferous tubule </u>drives the sperm to the epididymis, through the vas deferens, where the sperm can be for a long time and complete their maturation process.
  2. From the epididymis, the sperm pass to the seminal vesicle, which produces more seminal fluid to give nutrients to the sperm and facilitate its movement.
  3. Finally, and before being expelled outside, the seminal fluid receives the prostatic secretion in the prostatic urethra, a viscous and whitish liquid that completes the seminal fluid content.

The process of maturation of sperm is of  importance for the process of sexual reproduction.

Rina8888 [55]

Answer:

Dementia

Explanation:

Dementia is a condition that involves impaired mental ability and memory which is common among older adults. This condition, which is a major contributor to disability and placement of older adults in nursing homes, can be as a result of several factors of which nutrition has a major role to play. Metabolic and endocrine problem that results to the inability of the body system to regulate nutrients such as calcium and vitamin B-12, are some of the factors that triggers dementia in older adults. Also, nutritional deficiencies such as dehydration, inadequate intake of vitamin B-1, vitamins B-6, copper,vitamin E, and vitamin B-12 increases the chances of developing dementia in older adults.

Research shows that low levels of vitamin D can be linked to increased risk of developing dementia, and as such, supplements such as B-complex vitamin, vitamin C, and vitamin D is usually recommended for the prevention of dementia, especially when they are deficient in the diets taken.
