2. Major blood vessels connected to the
heart <3
• Aorta
• vena cavae
• pulmunary vein
• Artery
3. Aorta
• the largest artery in the body
originating from
the left ventricle of
the heart and
extending down to
the abdomen,
where it splits into
two smaller arteries.
The aorta distributes
oxygenated blood to
all parts of the body
through
the systemic
circulation.
4. venae cavae
• veins that return deoxygenated blood from
the body, into the heart. They both empty into
the right atrium.
5. Pulmonary vein
• large blood vessels that carry
oxygenated blood from the lungs to the
left atrium of the heart. In humans there are
four pulmonary veins, two from each lung. Its
unusual since almost all other veins carry
deoxygenated blood.
7. What capillaries do
• In the lungs, carbon dioxide is exchanged
for oxygen
• In the tissues, oxygen and carbon dioxide and
nutrients and wastes are exchanged
• In the kidneys, wastes are released to be
eliminated from the body
• In the intestine, nutrients are picked up, and
wastes released
8. Components of blood!
• Platelets
• Plasma
• FUNCTIONS
• Blood transports gases, nutrients, water,
wastes to and from all the cells of the body.
