The Circulatory System
Number of chambers in your heart
4
One drop of blood
About 5,000,000 Red Blood Cells
Mouth and nose
Air is inhaled
Hormones
Also carries substances, which control body processes, and antibodies to fight invading germs.
Three Kinds of Blood Vessels
Arteries Veins Capillaries
Full of oxygen
Blood from the left side pump is bright red
oxygen poor
Blood from the right side pump is dark red
lungs
Blood from through pulmonary veins back to the heart's left side pump and pumped out into the body.
Ventricles
Bottom two chambers
Artery
Carriers blood away from heart
Vein
Carries blood to heart
Arteries
Carry blood AWAY from the heart
Transportation system
Circulatory System nickname
Diaphragm controls breathing
Contracts to pull in air an relaxes to push out air
3 layers of skin
Epidermis dermis subcutaneous layer
Capillary
Gas exchange takes place
CO2
Gas exhaled
O2 enters blood and CO3 leaves the body
Gases exchanged
3 parts of circulatory system
Heart Blood Blood vessels
Circulation
Heart acts as double pump called?
Lung give it oxygen
Heart sends blood to lung before the rest of body
Death
Heart stops beating
Blood Vessels
Hollow tubes that circulate your blood
Diaphragm
Large muscle underneath your rib cage that controls breathing
Air travel way
Mouth pharynx trachea bronchi bronchioles alveoli blood stream

Number of chambers
Why hearts pump
Oxygen can be pumped to the rest of the body
liver
Plasma is made in the what?
6 functions of integumentary
Protecting the underlying skin Regulating internal body tempture Collecting sensory info from environment Producing vitamins Retaining necessary fluids Eliminating some waste
Veins
Receive blood from the capillaries Carry blood to the heart Transport waste-rich/ oxygen-poor blood back to the lungs and heart
on the inside
Smooth in the heart
Parts of the Circulatory System
The Heart The Blood The Blood Vessels
circle part
The heart, the lungs, and the blood vessels work together to the ? circulatory system.
blood
The plasma carries the cells throughout the body
Atrium
Top two chamber
on the outside
Tough in the heart
miles
Travels through thousands of ?of blood vessels
pulmonary arteries
Travels through to the lungs where it gets fresh oxygen and becomes bright red.
Heart
Where blood comes from
oxygen-rich blood.
Your body has a system of arteries supplying it with fresh,
Main artery
aorta
Upper Chamber
atria (single=atrium) receives blood coming in from the veins
White blood cells
attack and destroy germs when they enter the body.
Platelets
blood cells that help stop bleeding
Blood Takes
carbon dioxide and transports it back to the lungs
Muscular walls
help the heart pump blood
Plasma
liquid part of the blood
Bloods made up of
liquids, solids and small amounts of oxygen and carbon dioxide.
Valves
located inside the veins and allow blood to move in one direction.
half of your blood
made of plasma
Blood carries
nutrients, water, oxygen and waste products
heart size
of your fist
Circulatory System
oxygen and nutrients reach the body's cells, and waste materials are carried away.
Red blood cells carry
oxygen from the lungs to all the cells of the body.
Lower chambers
ventricles squeeze blood out into the arteries
