Standard
Identify and Investigate the general functions of the major
systems of the human body (circulatory, respiratory, and
musculoskeletal) and describe ways these systems interact
with each other to maintain Homeostasis
Objective
Students will identify and/or describe the general fuctions of
the major systems (Circulatory and Respiratory Systems) of
the human body
Students will identify and/or describe how the major systems
of the human body interact to maintain Homeostasis
Vocab
Circulatory System: the system that circulates blood and lymph
through the body
Heart: muscular organ that pumps the blood through the circulatory
system
Lungs: pair of organs in the ribs, consisting of sacs were air is inhaled,
so that oxygen can pass into the blood and carbon dioxide be
removed
Respiratory System: set of organs that allows a person to breathe and
exchange oxygen and carbon dioxide throughout the body
Essential Question
How do the Circulatory and Respiratory
Systems work together to allow the body to
maintain homeostasis?
Circulatory System
-The Circulatory System includes both the
Cardiovascular System and Lymphatic System
-The heart pumps blood around the body,
which serves as a transport system for cells,
chemical messages and removing wastes.
Blood
-Blood contains cells, fluid and other substances
-Arteries carry blood away from the heart
-Veins carry blood back to your heart
-Capillaries exchange Nutrients, Oxygen and
other substances throughout the body
Blood (cont)
-Plasma is the liquid part of the blood. It contains
the nutrients and red and white blood cells
-Red blood cells carry oxygen to every cell in your
body
-White blood cells fights pathogens to keep you
healthy
Respiratory System
-Takes in oxygen and releases carbon dioxide
-Exchanges these substances via capillaries
-Nose takes in oxygen, it goes down your throat, and splits
into the larynx, which vibrates to make you speak, and the
trachea, which goes into the lungs.
-Alveoli is in the lungs surrounded by blood vessels, which
when you breathe air is sucked into and out of them
Homeostasis
-The respiratory system allows for entry of oxygen and
releases carbon dioxide
-The circulatory system carries the blood around the body
-They work together to exchange gas, which is maintaining
homeostasis
Homeostasis (cont)
-If the circulatory system stopped functioning,
oxygen couldn't be carried around the body
-If the respiratory system stopped functioning,
oxygen couldn't be able to enter the body
