Brachiocephalic artery Essays

pig allow for a litter of 8 to 10 pigs. In fetal pigs, “the brachiocephalic artery splits into the right subclavian artery and the bicarotid trunk which then splits into the right and left common carotid arteries” (“Human/ Pig Comparisons”). Nonetheless, humans do not have a “bicarotid trunk and instead the left common carotid artery branches directly from the aorta” (“Human/ Pig Comparisons”). Fetal pigs also do not have iliac arteries that humans have. Additionally, because of the fact that pigs

the heart is artery; vein is towards the heart). If they connect arteries and veins then they are called capillaries and if an organ is receiving or returning the blood then the organ’s name is a part of the blood vessel’s name. Circle of Willis is a looped network (anastomosis) of arteries at the base of the brain. Branches of the internal carotid arteries form the front of the circle and branches of the posterior cerebral arteries form the back of the circle, with smaller arteries, collectively

Anatomy and Physiology Assignment 2 – Essay The Lymphatic System The lymphatic system has three primary functions. It drains excess interstitial fluid from tissue spaces and returns it to the blood, enabling circulatory blood volume to be maintained; transports lipids and lipid-soluble vitamins A, D, E, and K absorbed through the gastrointestinal tract; and is responsible for the body’s adaptive (specific) immunity, ie. defences against microbes that breach its innate (non-specific) immunity (eg

Question: What are the effects of temperature on heart rate and strength of contraction? The effects of temperature can either increase the heart rate or decrease the heart rate. The temperature can also effect the strength of contraction either by making the contraction stronger or weaker. Background: Explain on the cellular level how dropping warm Ringers solution on the frog’s heart would affect the cells of the SA node. Dropping warm Ringers solution on the frog’s heart would increase the heart

Pulmonary artery- transports deoxygenated blood away from the right side of the heart to the lungs (viii) Pulmonary vein- this is where oxygenated blood leaves the lungs and returns to the heart (ix) Aorta- passes blood from the left ventricle to the whole body The blood

Introduction Syringe Pump is another type of infusion pump which is small used to deliver small quantities of intravenous medications and fluids. It is also called as syringe driver. Most of the times this is used to infuse things and sometimes use to withdraw things.Actually we use syringe pumps applications where we need to deliver specific volume of fluid. We can use constant delivering rate or programmed flow rate. Most important part is exact deliver finite amount precisely because here we

A STUDY OF THE BIFURCATION OF SCIATIC NERVE AND ITS CLINICAL IMPORTANCE ABSTRACT Background:The sciatic nerve ,the principal nerve of the posterior compartment of the lower limb normally divides at the superior angle of popliteal fossa.Sometimes there could be higher division.,the knowledge of which is important in avoiding inadvertent injury during surgeries in the gluteal region . Materials and Method: The study was conducted in 64 lower limbs at Government Stanley Medical College,Chennai and

Introduction: BLOOD PRESSURE (BP) is defined as the "pushing force exerted by the blood against the vessel walls". This pressure is highest in the arteries and lowest in the veins. As a result, the blood moves from the arteries through the organs into the veins and back into the heart to begin the cycle over again. The heart acts as a pump to create the high arterial pressures that keep the blood flowing. Because it is the "driving pressure" that pushes the blood through the organs, the ARTERIAL

The Human Body System AC 2.1. Explain the structure and function of at least 3 to 4 systems 1) The Circulatory System; This system transports blood, full of oxygen and nutrients to and from the heart, and all around the rest of the human body. At the same time it transports out carbon dioxide and other unwanted material such as harmful minerals, waste material resulting from cellular breakdown, nitrogenous waste in liquid form, and food additives.These are then taken to the liver where they get

' hernia abdominal is the leakage of a viscus - or a part of it - from the abdominal cavity where it is normally contained. The herniation makes its way through a preformed orifice or an area of weakness in the cladding wall. Abdominal herniaAbdominal hernia is therefore the expression of a progressive weakening of the muscular and fascial walls, which under physiological conditions should keep the bowels in its proper place . abdominal hernias are called external because the viscera, slipping between

containing cholesterol and lipids on the inner most layer of the walls of large and medium –sized arteries. (Herbert, 2014) Atherosclerosis is the buildup of a waxy plaque on the inside of artery, the arteries are blood vessels that carry blood from the heart through the body, and they are lined by a thin layer of cells called the endothelium. The endothelium works to keep the inside of arteries toned and smooth, which blood keeps flowing. (Zarbock, et al, 2008) There are two major types

Beta Blockers That are Used in Managing Heart Failure Heart failure occurs when the heart is not able to pump or fill with blood to reach the body needs, leading to decrease in pumping action and cardiac output. The body will sense the hypo-perfusion of vital organs then activate the compensatory mechanisms. First compensatory mechanism is cardiac compensation by increasing the heart rate, contractility, or myocardial hypertrophy and remodeling. Additionally, systemic compensation by increasing

INTRODUCTION Chest pain is the most usual symptom at presentation in patients with acute myocardial infarction (AMI), even if it ishighly subjective, and the pain characteristics, severity and emotional consequences may vary widely.1, 2 An asymptomatic AMI is not necessarily less severe than a symptomatic event. Diabetic and elderly subjects are those who generally present with a lower severity of chest pain and at the same time represent the subgroups of AMI patients withworse outcome.3 Chest pain

substances (carbon dioxide and urea); this system is also responsible for circulating lymph (colourless fluid that contains white blood cells protecting organisms against disease). The cardiovascular system itself consists of the heart and blood vessels (arteries and veins), which pumps blood throughout the body. The heart itself is the variable pump consisting of striated cardiac tissue (dense arrangement of myosin and acting overlapping). Composed of 4 different compartments called the atria (right and

Aortic arches are also called as pharyngeal arteries. They are vascular structures that emerge from the ventricle of the heart. There are 6 pairs of these arches in embryonic stages which give rise to several major arteries later. They arise from the aortic sac and are present on the ventral and dorsal aorta. As discussed earlier that there are 6 pairs of aortic arches present in embryonic stages giving rise to several arteries are as follows: Arch 1st and 2nd: The first and second arches

Gout is the most common inflammatory type of arthritis affecting adults. The clinical syndrome of gout arises from deposition of urate crystals in joints,where they cause an inflammatory response, and in soft tissues where they do not. Crystal deposition occurs when serum becomes saturated with urate,the final breakdown product of purine metabolism.It is characterized by chronic hyperuricemia which is defined as serum urate levels above 6.8mg/dl,the level above which the physiological saturation

Introduction: Blood pressure is the measure of the force on arteries applying by blood as pumping out of the heart. Blood pressure measurement includes systolic and diastolic blood pressure. Systolic blood pressure (SBP) is the force that the heart needs to create to get the blood start to flow in our circulatory system; and diastolic blood pressure (DBP) is the pressure on arteries when the heart relaxes before pumping the blood out of the heart. Another factor that helps us to have a better understanding

inferior mesenteric vein and the median colic artery are located anterior and medial to the hernia (11). Right paraduodenal hernias Right paraduodenal hernias herniate to the Waldeyer’s fossa, posterior to the superior mesenteric artery and inferior to the third portion of the duodenum. On CT imaging the cluster of small bowel loops will be lateral and superior of the second portion of the duodenum and posterior and lateral of superior mesenteric artery (11). Pericaecal

Your heart is a pump. It's a solid organ about the measure of your clench hand, arranged marginally left of focus in your trunk. Your heart is partitioned into the privilege and the left side. The division shields oxygen-rich blood from blending with oxygen-poor blood. Oxygen-poor blood comes back to the heart subsequent to coursing through your body. The correct side of the heart, including the correct chamber and ventricle, gathers and pumps blood to the lungs through the pneumonic conduits.

Cardiovascular infection is a term that notice to extra than one sickness of the cardiovascular framework including the veins and heart. Despite the fact that it might seem like it, heart failure does not really imply that the heart has fizzled. Heart failure is a genuine condition in which the heart is not pumping blood around the body effectively. Heart failure influences around 5 million Americans. Approximately 550,000 individuals are determined to have heart failure every year. It's the main
