Vascular System & Glands
Question | Answer |
---|---|
Arteries carry what type of blood? | Oxygenated blood |
Veins carry what type of blood? | Deoxygenated blood |
Anastomosis | a vein can rejoin a vein; an artery can rejoin an artery; or a vein and artery can join. |
Plexus | Veins continue to branch until there is a large network of blood vessels in a general area. |
Arteriole | Smaller artery that branches off an artery and connects with a capillary. |
Atherosclerosis | Narrowing and blockage of the arteries by a buildup of fatty plaque. |
Bacteremia | Bacteria traveling through the vascular system |
Carotid Pulse | Pusle palpated from the common carotid artery. |
Embolus | Foreign materials (thrombus) traveling in the blood that can block the vessel. |
Hematoma | Bruise. |
Hemorrhage | Large amounts of blood that escape into the surrounding tissue without clotting when a blood vessel is seriously injured. |
Plaque | Substance which consists of cholesterol, calcium, clotting proteins, and other substances that can be found lining arteries . |
Thrombus | Clots that form on the inner blood vessel wall. |
Vasuclar System | System that consists of an arterial blood supply, a capillary network, and venous drainage. |
Vein | Type of blood vessel that reveals to the heart, carrying blood. |
Venous Sinus | Blood filled space between two layers of tissue. |
Venule | Smaller vein that drains the capillaries of the tissue area and then joins larger veins. |
What are the 10 major branches of the maxillary artery? | Middle Meningeal, inferior alveolar, deep temporal, pterygoid, mastered, buccal, posterior superior alveolar, infraorbital, greater palatine, sphenopalatine. |
The middle meningeal supplies what tissue? | Meninges and bones of vault. |
The inferior alveolar supplies what tissue? | The mandibular teeth, floor of the mouth, and mental region. |
The deep temporal supplies what tissue? | Temporalis Muscle. |
The pterygoid supplies what tissue? | Lateral and medial pterygoids. |
The mastered supplies what tissue? | masseter muscle. |
The buccal supplies what tissue? | buccinator muscle and buccal region. |
The infraorbital supplies what tissue? | The orbital region, face, and maxillary anterior teeth. |
The greater palatine supplies what tissue? | Hard and soft palates. |
The sphenopalatine supplies what tissue? | The nasal cavity and anterior hard palate. |

Step 7 of blood flow | Left & Right pulmonary arteries |
Step 8 of blood flow | Left and Right lungs |
Step 9 of blood flow | Four pulmonary veins |
Step 10 of blood flow | Left Atrium |
Step 11 of blood flow | Mitral Vein |
Step 12 of blood flow | Left Ventricle |
Step 13 of blood flow | Aortic Valve |

Within the vascular system a large network of blood vessels is a? | Plexus |
Blood filled spaces between two layers of tissue? | Venus Sinuses |
In most cases what drains the capillaries of a tissue are within the vascular system? | Venules |
What can cause narrowing and blockage of the arteries? | Fatty plaque |
What is a clot that forms in the inner vessel wall? | Thrombus |
An excellent example of variability in the vascular system | Lingual Veins |
The sternocleidomastoid muscle hides what artery? | Internal carotid artery |
How do blood vessels communicate with each other? | anastomosis |
The pterygoid plexus drains what? | Maxillary and mandibular teeth. |
Superficial vein + maxillary vein= | retromandibular vein |
Lacrimal gland secretion | tears |
Parotid salivary gland secretion | 25% of serous saliva |
Submandibulary salivary gland secretion | 60-65% of serous and mucous salvia |
Sublingual salivary gland secretion | 10% of predominating mucous saliva. |
Thyroid gland secretion | Thyroxin |
Parathyroid gland secretion | Parathyroid hormone |
Thymus gland secretion | thymosin |
