Lung development in your unborn child 2
Posted in 2013

Pseudoglandular Phase

Until about the 17th week of gestational age, well into the fetal period of development, lungs are in the pseudoglandular phase. The Brown University publication “Introduction to Fetal Medicine” notes that this phase is characterized by further branching of the original lung buds into smaller and more numerous areas. Each bud eventually becomes an independent respiratory unit, served by a bronchiole—a small branch off the trachea—and surrounded by capillary vessels that will bring blood to the lungs for oxygen.

Canalicular Phase

Lasting until approximately 25 weeks of gestational age, the canalicular phase sets up the air-blood barrier that will allow oxygen to enter blood in respiratory capillaries and carbon dioxide to flow out of respiratory capillaries into the lungs for exhalation. The University of Lausanne also notes that this phase is characterized by differentiation of the different tissue types in the lungs, meaning that air transport tissues become distinguishable from gas-exchange tissues.

My advise
1....   For development of any part or cell need sufficient oxygen...  Your child's lungs also need sufficient oxygen to develop
2....  Your oxygen levels are depend on your food
3...   Eat healthy food which consume less oxygen for your body needs and sufficient oxygen to your child

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

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
