DO NOW: The Pre-test
1) Identify and interpret the functions of the
circulatory system.
2) Compare and contrasts veins and arteries.
3) The level of CO2 in the blood affects
breathing rate. How would you expect
high levels of CO2 to affect the heart?
The process in which
cellular materials are
distributed (moved)
and absorbed (taken
in) throughout the
organism
Examples of Cellular
Materials
Water
Nutrients
Oxygen
Carbon Dioxide
Wastes
A circulatory system
•Heart
•Blood
•Blood vessels
Organ of the Human
Circulatory system
Made of cardiac
muscle
Responsible for
pumping blood through
the circulatory system.
•Liquid component of
circulatory system
•Present in the blood
vessels
•Carries cellular
materials throughout
the body
•Contains plasma,
blood cells, and
platelets
Tubes in the body that are used to
hold the blood
Pressure is applied to blood vessels to cause
the blood to move
1. Veins
2. Arteries
3. Capillaries
•Is a thin of blood
vessel that
contains valves
•Carries blood
TO the heart
•Is a thick blood
vessel
•Carries blood
AWAY from the
heart
•Smallest blood
vessels (Microscopic)
•One cell “thick”
(very thin)
•Where cellular
materials are
exchanged
ex.) lungs – alveoli
Small intesine - villi
CHECKING YOUR PULSE RATE
The heart speeds up when the blood volume
reaching your atrium increases. It also
speeds up when you exercise. The number
of heart beats per minute is your heart rate,
which can be measured by your pulse.
1. Why is your pulse a means to indirectly
measure heart rate?
2. Use values from your pulse rate (resting
and after exercise) to describe the change in
your pulse rate.
1. CORONARY CIRCULATION
ANY BLOOD FLOW GOING
TO OR FROM THE HEART
2. PULMONARY CIRCULATION
ANY BLOOD FLOW
GOING TO OR FROM
THE LUNGS
3. SYSTEMIC CIRCULATION
ANY BLOOD FLOW
GOING TO OR FROM
BODY PARTS OTHER
THAN THE HEART AND
LUNGS
Summary
The diagrams show various organ systems.
Cardiovascular diseases interfere most directly
with the normal functioning of
1) system E
2) system G
3) system C
4) system D
Which statement best describes
arteries?
1) They have thick walls and transport
blood away from the heart.
2) They have thick walls and transport
blood toward the heart.
3) They have thin walls and transport
blood away from the heart.
4) They have thin walls and transport
blood toward the heart.
In a human, the movement of
glucose from the digestive tract
to muscle cells is most directly a
result of
1)
2)
3)
4)
ingestion and digestion
absorption and circulation
anaerobic respiration
protein synthesis
Which two systems are most directly
involved in providing molecules
needed for the synthesis of fats in
human cells?
1)
2)
3)
4)
digestive and circulatory
excretory and digestive
immune and muscular
reproductive and circulatory
