Respiration & Circulation
7.12 Organisms and Environments. The student knows that living systems at all levels of organization demonstrate the complementary nature of structure and function. The student is expected to:
(B) Identify the main functions of the system of the human organism, including the circulatory, respiratory,
(B) Identify the main functions of the system of the human organism, including the circulatory, respiratory,
Respiratory SystemFunction of System: To provide the body with oxygen (O2) and remove carbon dioxide (CO2) from the body. Allows the body to breathe- inhale and exhale
Organs: lungs, trachea, bronchi, bronchioles, alveoli, pharynx, nose/mouth, and diaphragm (a muscle) Comparison to cell Function: This system is similar to the cell membrane allowing cretin things in to and out of the cell.

Circulatory/Cardiovascular SystemFunction of System: To transport and deliver materials throughout the body. The heart pumps blood, circulating it between the body heat and lungs.
Organs: heart, blood vessels: artery, veins, capillaries, and blood- technically it’s a tissue! Comparison to cell Function: This system would be similar to the functions of a golgi body with in a cell identifying and delivering materials.

Respiration VideosThis first one is a MrCoachRisigner original production. The ending is goofy but the content is great. Heavy focus on Breathing Vs. Cellular Respiration.
The next two videos are from "Crash Course" on YouTube... they are professionally done and cover way more detail then you will ever be quizzed or tested on in 7th grade. But they are well done, accurate, and entertaining.
his video is not nearly as full of big words as the last one. More for "kids" not the highly skilled middle schoolers in my class but it is shorter and easier to follow.

Circulatory/Cardiovascular Video'sAwesome detail on the Pumping of the heart! Does a really nice job of explaining the "FUNCTION" of the system.
This one is a bit heavy on the structure of each blood vessel but if you get past the different layers of each blood vessel it really nice to understand where blood goes when it leave the heart and how it gets back.
And lastly the blood. If you have another 10 min go for it!
