Blood vessels are divided into five (5) groups which are?
Arteries, Arterioles, Capillaries, Venules, Veins
Small subdivisions of the arteries, carry blood into the capillaries?
Are tiny, thin-walled vessels that allow for exchanges between systems?
These connect the arterioles and the venules?
Small vessels that receive blood from the capillaries and begin its transport back toward the heart?
Are vessels formed by the merger of venules, they continue the transport of blood until it is returned to the heart?
Vessels are subdivided into to two (2) groups?
Pulmonary and systemic circuits
This circuit delivers blood to the lungs where CO2 is eliminated and O is replenished?
Pulmonary Circuit
The pulmonary vessels that carry blood to and from the lungs include?
Pulmonary artery and its branches, capillaries in lungs, and pulmonary veins.
Carry blood from the RV to the lungs?
Pulmonary artery
Carry blood to the left atrium?
Pulmonary veins
What is the only artery that carries deoxygenated blood?
Pulmonary Artery
What is the only vein that carries oxygenated blood?
Pulmonary vein
All arteries except the pulmonary artery carry what kind of blood?
Oxygenated blood
All veins except for the pulmonary vein carry what kind of blood?
Deoxygenated Blood
These vessels supply nutrients and oxygen to all the tissues and carry waste materials away from the tissues for disposal?
Systemic Circuit
Receives blood from the LV and then branches into the systematic arteries carrying blood to the tissues?
The Systemic Circuit includes?
Aorta, capillaries, systemic veins
These vessels have thick walls because they must be strong enough to receive blood pumped under pressure from the hearts ventricles?
How many tunics of an artery are there?
The innermost membrame of simple, flat epithelial cells make up this tunic?
A smooth surface over which the blood flows easily?
The middle and thickest layers of an artery, which is under control of the ANS?
Middle Tunic
Is comprised of smooth muscle?
