Support- Blood Vessels & Blood Components

Blood Vessels

Closed Circulatory System

• Blood is pumped through vessels.

Blood Vessels

• Arteries
• Veins
• Capillaries

Arteries

• Thick walled
• Elastic connective tissue
• Transport blood AWAY from the heart

Type of blood transported

• Oxygenated Blood- oxygen-rich blood
• Oxygen is picked up in the lungs

Veins

• Not elastic
• Carry blood TO the heart

contain valves

• Keep blood flowing in one direction
• Help push blood forward counteracting gravity

Type of blood transported

• Deoxygenated blood: oxygen-poor
• Oxygen is distributed to all cells of the

body

Capillaries

• One cell thick
• Where diffusion/exchange of

– Nutrients
– Oxygen
– wastes

Type of blood transported

• Oxygenated and deoxygenated

Blood

• Maintains homeostasis

• Regulates body temperature
• Transports materials to and

from cells

Blood Components

•Plasma
•Red Blood Cells
•White Blood Cells
•Platelets

Plasma

Transports:

–Blood cells
–Hormones
–Water
–Nutrients

-sugars

-amino acids

Red Blood Cells

•Transport O2 on hemoglobin

RBC

Made in bone marrow
Life Span: ~120 days

White Blood Cells

• Engulf (eat) pathogens & make antibodies

• Contain a nucleus

•Made in: Bone Marrow

Platelets

• Clot blood
• Formed in bone marrow
