Transcript

  • 1.  * Your cells are the basic living units that make up your body.  *Groups of cells come together to form specialized tissues.  * Groups of tissues come together to form your organs.  * Organ systems – groups of organs that perform a specific purpose in the human body.
  • 2.  Here are the body systems in order of importance:  Nervous System  Endocrine System  Cardiovascular System  Respiratory System  Digestive System  Urinary System  Muscular System  Skeletal System  Integumentary (Skin) System  Immune System (includes Lymphatic System)  Reproductive System
  • 3.  These two systems are co-directors of ALL of your body’s moment-to-moment activities. The Nervous System is made up of the brain, the spinal cord, and nerves. One of the MOST important systems in your body, the N.S. is your body’s control system. It sends, receives, and processes nerve impulses throughout the body, which tell your organs and muscles what to do and how to respond to the environment. The most important system is Autonomic N.S. which regulates involuntary action, such as HEART BEAT and digestion.  The Endocrine System is made up of a group of glands that produce the body’s long-distance messengers, or hormones, which control body functions, such as metabolism, growth, and sexual development..
  • 4.  Your Respiratory System brings in the oxygen that your Cardiovascular system delivers to all of your calls. Your Respiratory System also plays a vital role in maintaining your blood pH.
  • 5.  Your Digestive System provides fuel for all of your other organ systems to use to produce energy.  Your Urinary System is essential to maintaining fluid and pH balance within all of your organ systems.
  • 6.  Your Muscular System allows you to move (making the rest of your organ system relevant to your existence). It also serves as an important reservoir for your Endocrine System.  Your Skeletal System provides physical protection and structural support for your other organ systems.  Your Integumentary (skin) and Immune Systems play critical roles in preventing life-threatening infections of all of your other organ systems.  Your Reproductive System is a system of organs within an organism which work together for the purpose of reproduction.
  • 7.  These systems don’t just exist as individual units. The final product of these cooperating system is one unit called THE BODY. Each system depends on the others, either directly or indirectly, to keep the body functioning normally.  Each of your organ systems are groups of organs that work TOGETHER to carry out specific duties in your body.  Some organs contribute essential work to MORE than ONE organ systems.  Finally, it’s important to point out that ALL of your organ systems AFFECT one another.
  • 8.  The Nervous System is one of the most important systems in your body, because it your body’s central system. There are 3 parts of your N.S. that work together:  1. The central N.S. which consists of the brain and spinal cord. It sends impulses and analyzes information from the sense organs, which tell your brain about things you see, hear, smell, taste and feel.  2. The peripheral N.S. which includes the craniospinal nerves that branch off from the brain and the spinal cord. It carries the nerve impulses from the central N.S. to the muscles and glands.  3. The autonomic N.S. which regulates involuntary action, such as HEART BEAT and digestion.
  • 9. All systems are vital to our survival, but if I have to pick the most important ones, I would go with The Nervous and the Cardiovascular Systems. The Circulatory System is our body’s transport system, which is made up of the vessels and the muscles that help and control the flow of the blood around the body. Then the heart pumps the blood and the arteries and veins transport it.  So the reason why I picked the Nervous System on the first place is because as I mentioned before the Autonomic N.S. performs the very important function such as a HEART BEAT. And the Peripheral N.S. carries the nerve impulses from the Central N.S. to the muscles (which also control the flow of the blood around the body) and glands. So if the N.S. wont send the nerve impulses to the muscles, they wont be able to help to control the blood flow.  And as we all know that if the heart fails/stops working , we go to HEAVEN  Least important would be the Reproductive System, because we can survive and live a full life without it- although if no one had one, the species would die out !!!!
