A blood vessel is a tubular structure carrying blood through tissues and organs

There are three varieties of blood vessels: arteries, veins, and capillaries

Blood vessels provide two important means of measuring vital health statistics: pulse and blood pressure

Page 3: Blood & Blood

Arteries - carries blood away from heart

Capillaries - connects arteries to veins.

Veins - carry blood back to the heart.

Page 4: Blood & Blood

Largest Artery in the body

Connected to left ventricle

Distributes Oxygenated Blood from the left ventricle of the heart to every organ.

Ends in abdomen after bifurcation (to divide or fork into two branches) of the abdominal aorta in the two common iliac arteries.

Iliac arteries are several anatomical structures located in the pelvis (base of the spine to the rear limbs)

Page 5: Blood & Blood

Returns Deoxygenated Blood to the heart

Cranial Vena Cava - above the heart, forms from convergence of the left and right brachiocephalic veins

Caudal Vena Cava - travels up alongside the abdominal aorta with blood from the lower part of the body

Page 6: Blood & Blood

Carries Deoxygenated Blood from the heart to the LUNGS~

One of the only arteries that carry deoxygenated blood

The main Pulmonary artery begins at: base of the RIGHT VENTRICLE

Branches out into 2 pulmonary arteries, left and right, which carry deoxygenated blood to the lungs.

Red Blood Cells

White Blood Cells

Platelets

Carried in Plasma

Page 9: Blood & Blood

Red blood cells (erythrocytes): shaped slightly indented, flattened disks.

RBCs contain: iron-rich protein hemoglobin. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs.

As the blood travels through the body, the hemoglobin releases oxygen to the tissues.

White blood cells (leukocytes): key part defending the body against infection.

Less WBCs produced than RBCs, but production may be increased.

Granulocytes and lymphocytes (types of WBCs) travel along the walls of blood vessels, fighting germs and may attempt to destroy cells that have become infected or have changed into cancer cells.

After the body has been challenged by infections, lymphocytes "remember" how to make the specific antibodies to counter the virus should it enter the body again.

Page 13: Blood & Blood

Platelets (thrombocytes): tiny oval-shaped cells

Made in: bone marrowHelps in clotting blood.When a blood vessel breaks, platelets gather in the area and help seal off the leak.

Platelets and clotting factors (Proteins that help with clotting) work together to form solid lumps, sealing wounds and cuts to prevent bleeding from injured areas.
