Inferior vena cava

2. Physiology Q=(P1 - P2)/ R Q= flow The amount of a liquid moving past a point in a given amount of time. P=Pressure (P1-P2) The amount of force placed on an artery at any given point in time. R= resistance Is the force that must be overcome for flow to occur. Describe the basic flow equation and resistance equation as they relate to vascular flow. b. Define Poiseuille’s Equation, and describe the effect on blood flow of a change in each variable. Poiseuille's equation states that the…

capillary into the tissues of the body. RBC exchanges oxygen with carbon dioxide, as they are now known as deoxygenated RBC. The deoxygenated RBC then travels through the venules, veins, and returns to the right atrium of the heart by the superior or inferior venacava.…

What is the cardiovascular system? The cardiovascular system functions when it transports oxygen from the lungs to the tissues around the body. While also transporting oxygen around the body this system transports carbon dioxide which is a waste product from the body to the lungs. The cardiovascular system works when a person breathes air through their mouth and nose and then it travels the lungs. Oxygen from the air is slowly absorbed into the bloodstream through the lungs. The heart then…

heart is one of the most important organs in your body. Your heart helps the all the blood in your body circulates. For does who do not know the function of the blood-flow I will explain. On the right side of the heart we have two Vena Cava in which is superior and inferior. Next we have the right atrium, from the right atrium the flows through the tricuspid valve. Upcoming the blood flow goes through the right ventricle, to the pulmonary valve, succeeding to the pulmonary artery than to the…

different routes, for examples through the lymphatic chain or blood borne spread. For instance rectal cancer can spread to the liver by the venous drainage of the gastrointestinal system. It can also spread to lung when tumor embolus into the inferior vena cava (IVC) (Washington & Leaver, 711) . As a result of this, if a tumor to metastasizes in the digestive system it is going to be base on the lymphatic chain or the follow of blood. The prognosis of digestive system cancer depends on the…

(+Chorda Tympani from Facial Nerve) →Submandibular Ganglion Inferior Alveolar Nerve Pathway: CNV3 Mandibular Nerve → Inferior Alveolar Nerve →Inferior Dental Nerves → Mental Nerve (+ Nerve to Mylohyoid) Lingual Artery Pathway: External Carotid Artery→ Lingual Artery → Sublingual Artery, Deep Lingual Artery, Dorsal Lingual Artery Inferior Alveolar Artery Pathway: External Carotid Artery → Maxillary Artery → [Mandibular Foramen] → Inferior Alveolar Artery → [Mental Foramen] → Mental Artery…

Operative Management of Portal Vein/SMV Trauma: Can We Just Ligate Case Scenario: A 21-year-old male presented to the emergency department after he was stabbed in the abdomen. On examination, his vital signs were significant for a systolic blood pressure of 70 mmHg, heart rate of 120 beats per minute, and a right upper quadrant stab wound. Given the concern for intra-abdominal bleeding, he was taken to operating room for exploratory laparotomy. The patient had a large right zone 1…

ABOUT LIVER TRANSPLANTATION What is a liver transplant? A liver transplant is a procedure performed to replace a diseased liver with a healthy liver from another person. During the liver transplantation surgery, the surgeon removes the diseased liver and replaces it with a healthy one. The surgery generally takes 4 - 12 hours to perform, and patients stay in the hospital for up to 3 weeks after the surgery. Most patients return to normal or near-normal activities 6 - 12 months following the…

1. Dr. Baker spends a long time listening to (auscultating) Caleb’s heart. a. Where on the thoracic surface do you auscultate to the tricuspid, mitral (bicuspid), pulmonary, and aortic valves? The tricuspid valve is between the right atria and right ventricle. Therefore, you would auscultate the tricuspid valve on the left side of the heart, between the fourth and fifth rib (or intercostal space) and lower left sternum area. The mitral valve is between the left atrium and left ventricle.…

open the pulmonary arteries examining them for thromboembolism. After examining the pulmonary arteries, I detach the heart from the lungs by cutting the pulmonary arteries and pulmonary veins close to the pulmonary hila. Next I need to cut the inferior vena cava as it comes through the diaphragm. After this the heart can be removed and weighed. Next, the lungs must be freed from the remaining hilar structures by cutting along the pulmonary hilum. After the lungs are freed they need to be weighed…
