LIFE PROCESSES

Hello again dear friends!

In this post, we will review some basic concepts about the life processes. As you well know, life processes are necessary to maintain life. They are carried out by living things. Just click on the underlined words (the blue ones) and the videos will be opened.

Nutrition is the process which provides your body with all the nutrients and energy that are necessary for life. It involves four processes: digestion (the main organs are the stomach and the intestines), respiration (the main organs are the lungs), circulation (the main organ is the heart) and excretion (the main organs are the kidneys).

The process of sensitivity is the ability to detect and respond to changes in the environment. It involves the sense organs (eyes, ear, nose, tongue and hands), the nervous system (the brain and the nerves) and the locomotor system (made up of the skeletal system and the muscular system).

The process of reproduction allows us to have offspring (children/babies) similar to ourselves through the sexual reproduction. Male reproductive organs and female reproductive organs are different and they develop during the stage of adolescence. The baby develops and become larger inside the mother’s uterus. This period is called pregnancy and lasts about nine months.

Thanks for visiting. Regards, Christopher.
