Human Anatomy & Body Systems

Learn about human body systems! Understand how your circulatory, immune, and nervous systems work.

Anatomy, Facts & Functions The information contained in this link will provide you with everything you need to complete the webquest below. Circulatory System moves blood, nutrients, oxygen, carbon dioxide, and hormones, around the body Urinary System Eliminates waste Immune System Aids the body in defending against bacteria, viruses and pathogens. Nervous system controls voluntary actions (muscles) and involuntary actions (breathing) How the immune system works Match the type of cell with its job as described in the video above. B cell Tag invaders with antibodies so other immune system cells know what to do with them. Killer Cell To devour or kill invaders Cytotoxic Cell To destroy infected body cells before a virus has a chance to multiply. Helper T Cell To coordinate immune system attack by recruiting and activating other immune system cells. The urinary system aids the body in the following (use the information you read in the article at the beginning to answer the question): communicate between cells moves substances to or from cells disposes of dissolved waste molecules Above is a depiction of the human circulatory system. The circulatory system is responsible for the ability of the body to do all of the following except: Move substances to or from cells dispose of dissolved waste molecules respond to changing demands by increasing or decreasing heart rate to maintain homeostasis respond to changing demands by increasing or decreasing blood flow to maintain homeostasis Which of the following is the correct answer from smallest to largest? tissue-organ-system-cell cell-tissue-organ-system cell-organ-tissue-system What system receives oxygen and gets rid of carbon dioxide? Heart Muscular system Respiratory system How does the digestive system work with all the other systems? The digestive system puts oxygen into the body The digestive system transports blood to all the other systems The digestive system allows the body to move The digestive system gives the body energy and nutrients Which system detects information from the environment and directs the way your body responds to this information? respiratory nervous circulatory excratory
