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 1 of blood flow. | Superior and Inferior venae cavae |
| Step 2 of blood flow. | Right Atrium |

| Step 4 of blood flow | Right Ventricle |
| Step 5 of blood flow | Pulmonary Valve |
| Step 6 of blood flow | Pulmonary Trunk |
| 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 |
| Step 14 of blood flow | Ascending and descending aorta |
| 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 |
