What are the main organs and tissues found in the 8 main body systems: nervous, circulatory, digestive, excretory, endocrine, skeletal, muscular, and respiratory, and how do they interact with each other.
Answers
Answer:
Have you ever wondered how your food is digested, or how you can breathe, or even move your arms? If you think about it, it's pretty amazing that the human body can do all of these things and more. These actions are made possible by what are called organ systems which are collections of organs, body parts and tissues that work together for a common goal. For example, each one of your bones are part of the skeletal system; they work collectively to provide support and movement so that you can walk and run. Your bones also work together to protect your important internal organs, such as the heart, lungs and brain. Other organ systems present in your body are the circulatory, respiratory, muscular, digestive, integumentary, endocrine, reproductive, and nervous systems. All of these systems have specific functions but they cannot function independently, meaning that they rely on all the other systems in order to work properly. Each system is very important and every person has them. Below you will find a brief overview of each body system along with helpful educational links for adults and instructional links for teachers.
