Insights Human Body Systems

How do the respiratory and circulatory systems work together to get oxygen to the cells?

How do cells throughout the body get oxygen needed for life?

What does the respiratory system do? How does it work?

6A(6-8)#1: Like other animals, human beings have body systems for obtaining and providing energy, defense, reproduction, and the coordination of the body functions.

6C(6-8)#3: ~~To burn food for the release of energy stored in it, oxygen must be supplied to the cells, and carbon dioxide removed~~ . Lungs take in oxygen ~~for the combustion of food~~ and they eliminate the carbon dioxide. The urinary system disposes of dissolved waste molecules, the intestinal tract removes solid wastes, ~~and the skin and lungs rid the body of heat energy~~. The circulatory system moves all these substances to or from cells where they are needed or produced, responding to changing demands.

6C(6-8)#2: For the body to use food for energy and building materials, the food must first be digested into molecules that are absorbed and transported to cells.

NSES (5-8): The human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control and coordination, and for protection from disease. The systems interact with one another.

Getting Started discussion driven by questions on page 196 will help to identify what students know and don't know about the respiratory system.

Journal Entry: What might cause an individual to have a faster breathing rate? A slower one? What are some reasons a person might be able to breathe a large amount of air?

Do students understand how the parts of the respiratory system work together to supply the body with oxygen?
Can students explain how air gets into the body?
Are students able to connect the respiratory system to the circulatory system?
