GLE 3.2.C.f: Explain the interactions between the circulatory and
respiratory systems in exchanging oxygen and carbon dioxide
between cells and the atmosphere (when oxygen enters the body,
passes into the blood stream, and is transported into the cell; carbon
dioxide is transported out of the cell, passes into the blood stream,
and exits the body).

1. Explain the interactions between the circulatory and respiratory systems in exchanging
oxygen and carbon dioxide between cells and the atmosphere (when oxygen enters the body,
passes into the blood stream, and is transported into the cell; carbon dioxide).
GLE: 3.2.C.f: DOK 2: Points Possible: 2
Scoring Guide: 2 point answer: I expect you to write like the following samples.
One study tip: Practice writing it 10 times or make flash cards and study them for the next
three months for 5-10 minutes every other day.
The respiratory system includes the lungs, trachea, pharynx, bronchus,
alveoli, mouth and nose. The respiratory system takes in or inhales oxygen and
exhales or puts out carbon dioxide waste products.
The circulatory system includes the heart, valves, arteries, veins and
capillaries. The circulatory system transports or brings oxygen to the respiratory
system and other systems in the body. Oxygen from the atmosphere enters through
the nose or mouth. Oxygen then passes through the throat (pharynx), and then it goes
through the windpipe (trachea). The trachea splits into two as it enters both lungs.
These are now called the bronchus. The bronchus divides or segments into bronchi.
The oxygen goes through the bronchus to the bronchi which then branch into a very
small bronchiole tree. The final branches are called atria and they end in single celled
sacs called alveoli. Every cell in the body requires oxygen to do their jobs and these
cells release carbon dioxide as waste when they are done. This waste must be
eliminated out of the body or it will cause damage or death. 1 point
The circulatory system has capillaries attached to the alveoli in the respiratory
system. Carbon dioxide and oxygen are exchanged here or in other words, the
oxygen enters the blood and carbon dioxide leaves the blood at this site. 1 point
