Cardiovascular System: How our body delivers materials
Systemic Delivery:
• We need to get materials to all our cells!
• Materials include: Nutrients and Gasses (Glucose, CO2, O2)
• Primary mechanism of delivery is the Cardiovascular System
•
2 Primary routes of entry to the body are the Respiratory and
Digestive Systems
• Both systems introduce materials to the bloodstream for systemic
distribution
Cardiovascular System: How our body delivers materials
The Cardiovascular System is a
very effective system to deliver
gasses, nutrients and transport
waste (or anything else!)
The Digestive System and
Respiratory Systems connect to
the Cardiovascular System –
allowing entry of materials into
our body.

Cardiovascular System: How our body delivers materials
The Cardiovascular System
A fluid transport system that consists of
the heart, all the blood vessels in the
body, the blood that flows through these
vessels, and the bone marrow tissue in
which red blood cells are formed.

Plasma: Water (92%) and
Proteins
Plasma Proteins
Fibrinogen: Helps Clotting
High-Density Lipoproteins
(HDLs) carry lipids &
cholesterol from the blood
and tissues to the liver.
Low-Density Lipoproteins
(LDLs) carry lipids &
cholesterol to the blood and
outlying tissues from the liver
and small intestine

LDL and Heart Disease:
Heart Attack: Blockage (complete) of a coronary artery. Can lead to the
death of heart cells (no O2, glucose). This means your heart may not
be able to contract or sustain a normal rhythm.

Cardiovascular System: How our body delivers materials
Bone marrow is the soft tissue found
inside of bones.
In humans, red blood cells,
white blood cells and
platelets are produced by
red bone marrow in the
heads of long bones
This process is known as
hematopoiesis

Cardiovascular System: How our body delivers materials
Blood Vessels
Arteries: Carry blood away from
the heart (usually oxygenated)
Veins: Carry blood back to the
heart (usually deoxygenated)
Capillaries: Tiny blood vessels
that connect arteries and veins.
Where blood bathes cells

In the respiratory system

The heart is the organ that
powers this ongoing cycle
Blood Vessels and Circulation
The Heart:
Pumps oxygen poor
blood from the body
(Veins) into the lungs
Pumps oxygen rich
blood to the body
(Arteries)
