Endocrine system - Thyroid Gland  2
Posted in 2013

The thyroid makes two hormones that it secretes into the blood stream. One is called thyroxine; this hormone contains four atoms of iodine and is often called T4. The other is called triiodothyronine, which contains three atoms of iodine and is often called T3. In the cells and tissues of the body the T4 is converted to T3. It is the T3, derived from T4 or secreted as T3 from the thyroid gland, which is biologically active and influences the activity of all the cells and tissues of your body.
The T4, or rather the T3 derived from it, and the T3 secreted directly by the thyroid gland influence the metabolism of your body cells. In other words, it regulates the speed with which your body cells work. If too much of the thyroid hormones are secreted, the body cells work faster than normal, and you have hyperthyroidism. If you become hyperthyroid because of too much secretion of the hormones from the thyroid gland, the increased activity of your body cells or body organs may lead, for example, to a quickening of your heart rate or increased activity of your intestine so that you have frequent bowel motions or even diarrhoea.
On the other hand if too little of the thyroid hormones are produced (known as hypothyroidism), the cells and organs of your body slow down. If you become hypothyroid, your heart rate, for example, may be slower than normal and your intestines work sluggishly, so you become constipated.

My advise
1...  It is the system which will regulate the activity of various cells or organs
2...  The major glands of endocrine system are the  hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system; it has a role in hormone production as well as in digestion.
3... These hormones are chemical messengers created by our body
4..  They transfer the messages of various glands to coordinate with one another.
5... We are discussing on reproductive organs how they protect and regulate functions of these organs.  All of you know about reproductive organs
6... Protect this system with your healthy habits, healthy life style, healthy food etc.. to avoid various health problems caused and particularly on reproductive system
7.. Thyroid Gland is important gland situated in the neck.  It plays the role in bone growth up to young age then it plays to protect entire bone system.  In children it plays the role to develop brain cells and nervous system.

Possible Male Fertility problems  My memories Possible Male Fertility Problems Posted in 2015  Sexually Transmitted diseases or other infections.  G enital infections such as chlamydia  and gonorrhea  can cause infertility in men. The infertility can often be resolved by treating the infection. Blockages, birth defects   , or physical damage . In  some cases, men are born with blockages in parts of the testicle or other abnormalities that prevent sperm from getting into the semen. Physical trauma to the testicles, prostate, and urethra can also result in fertility problems. Surgery can sometimes correct the problem. Retrograde ejaculation.  In  this disorder, semen doesn't come out of the penis  during ejaculation, but instead enters the bladder. It can be caused by diabetes , certain medications , and surgery to the bladder, prostate, or urethra. Genetic diseases .  Although it's rare, genetic illnesses such as cystic fibrosis  or chromosomal disorders can c

Reproduction of Human Beings - Male Brought to U.... http://successgain.us     and    http://successgain.info My memories Reproduction of Human Beings- Male Posted in 2013 Reproduction in human beings is by sexual reproduction where both the male and female gametes fertilize to give rise to an embryo. The fertilization of human embryo occurs inside the body of the female. Thus, it is called Internal Fertilization. Human Beings are viviparous organisms who give rise to Embryos directly instead of laying eggs. Let us understand a little more about the male and female reproductive organs and the process of fertilization in them. Male Reproductive System Testes:  Male humans have two testes. They are situated in a bag of skin known as the scrotum. Scrotum lies outside the pelvic cavity. Sperm Duct:  These are thin ducts that arise from the testes. Prostrate Gland:  This gland is an accessory gland in males which pours its secretions into the sperm duct along with the

At present,  type 1 diabetes  cannot be prevented. The environmental triggers that are thought to generate the process that results in the destruction of the body’s insulin-producing cells are still under investigation. While there are a number of factors that influence the development of  type 2 diabetes , it is evident that the most influential are lifestyle behaviours commonly associated with urbanization. These include consumption of unhealthy foods and inactive lifestyles with sedentary behaviour. Studies from different parts of the world have established that  lifestyle modification  with  physical activity  and/or  healthy
