20 Fun Facts About The Skeletal System

Readers will bone up on their knowledge of the human body with this enlightening text about the skeletal system. The skeleton forms framework for the entire body. It protects the organs, stores minerals, and makes it possible for the body to move and function. Readers will study the parts of the skeletal system, learn about types of bones, and discover how the body changes over time. Useful diagrams help readers visualize abstract concepts, and attention-grabbing photographs enrich the comprehensive text.

Muscles do far more than help us lift heavy things off the ground. Muscles make the heart work well and move food through the stomach. They allow us to walk, swim, and even draw! In the fun fact file format, this book introduces readers to the most interesting aspects of the muscular system, including information from the science curriculum, through engaging and sometimes gross tidbits! Detailed diagrams and full-color photographs support each fascinating fact, guiding readers to better body literacy and understanding of this important body system.

Have you ever wondered how the brain is able to control so many important things in the human body? Or how the spinal cord is structured? This volume engrosses and engages reader in this fascinating topic in an easy-to-follow format that adds to the accessibility of this text. Graphic organizers, a body system diagram, and full-color photographs reinforce the science curriculum content contained in each fun fact. Even reluctant readers will marvel at all the amazing processes of the nervous system when explained through gross, unbelievable, and amusing tidbits on each page.

When talking about the digestive system, a few topics must be covered: vomit, the intestines, and poop! All readers can enjoy these and many more topics about the grossest of the body systems in this friendly, fun fact format. From the mouth and esophagus to the small and large intestine, readers take a journey through the human body via the digestive tract, and enjoy learning about processes the digestive system does without us even knowing. The bright images and labeled diagrams encourage body literacy and support science classroom learning.

The human body is a biological machine made of body systems; groups of organs that work together to produce and sustain life. Sometimes we get lost while studying about cells and molecules and can’t see the forest for the trees. It can be helpful to step back and look at the bigger anatomical picture. The human body is a complex, highly organized structure made up of unique cells that work together to accomplish the specific functions necessary for sustaining life. The biology of the human body includes Physiology (how the body functions) Anatomy (how the body is structured) Anatomy is organized by levels, from the smallest components of cells to the largest organs and their relationships to other organs. Gross anatomy is the study of the body's organs as seen with the naked eye during visual inspection and when the body is cut open for examination (dissection). Cellular anatomy is the study of cells and their components, which can be observed only with the use of special techniques and special instruments such as microscopes. Molecular anatomy (often called molecular biology) is the study of the smallest components of cells at the biochemical level. The human body is a complex and intricate piece of engineering in which every structure plays a precise role. There are approximately 200 bones, 650 muscles, 79 organs, and enough blood vessels to circle the Earth twice! Anatomy and physiology change remarkably between fertilization and birth. After birth, the rate of anatomic and physiologic changes slows, but childhood is still a time of remarkable growth and development. Some anatomic changes occur past adulthood, but the physiologic changes in the body's cells and organs are what contribute most to what we experience as aging Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The job of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide, and hormones, around the body. It consists of the heart, blood, blood vessels,arteries and veins. The digestive system consists of a series of connected organs that together, allow the body to break down and absorb food, and remove waste. It includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. The liver and pancreas also play a role in the digestive system because they produce digestive juices. The endocrine system consists of eight major glands that secrete hormones into the blood. These hormones, in turn, travel to different tissues and regulate various bodily functions, such as metabolism, growth and sexual function. The immune system is the body's defense against bacteria, viruses and other pathogens that may be harmful. It includes lymph nodes, the spleen, bone marrow, lymphocytes (including B-cells and T-cells), the thymus and leukocytes, which are white blood cells. The lymphatic system includes lymph nodes, lymph ducts and lymph vessels, and also plays a role in the body's defenses. Its main job is to make is to make and move lymph, a clear fluid that contains white blood cells, which help the body fight infection. The lymphatic system also removes excess lymph fluid from bodily tissues, and returns it to the blood.

A version of the OpenStax text

A body without bones simply couldn't work! The skeletal system of the human body is the focus of this valuable volume, which centers on key concepts in elementary curricular content and uses at-level language to make biology accessible and interesting to young scientists. Readers will appreciate the fascinating fact boxes and many colorful photographs featured throughout the text. A concluding activity will help them understand how essential science concepts are truly relevant to their lives.
