The Mammalian Circulatory and Gas Exchange Systems Radwa Abdallah Professor Yan Xu Fundamentals of Biology II Lab February 20, 2014 Objectives The objectives of the Circulatory System laboratory experiment included observing and learning to identify the structural characteristics, mostly arteries and veins, in the chest cavity of the fetal pig, which would further the understanding of the heart and lungs in most other mammals; another objective was to understand blood pressure and heart

A venous leg ulcer is a chronic wound as it takes longer than six weeks to heal. It is caused by venous hypertension which is high blood pressure exerted in the veins of the legs which causes damage to the skin. Fluid can leak from the veins and pool under the skin causing swelling and thickening, this then leads to the skin breaking down to form an ulcer. Before a venous ulcer can be treated it is important to rule out peripheral arterial disease being the cause of the ulcer. Symptoms

Cardiovascular System The cardiovascular system transports oxygen around the body to the working muscles. It also helps to transport waste products such as CO2 that is caused by aerobic respiration so that it can be disposed. Your heart is a fist sized muscle that is located on the left side of your chest and is an involuntary muscle and an adult heart approximately weighs 255grams. The heart is separated by a septum. The left side of the heart is thicker than the right because it has to pump oxygenated

Cardiovascular System The cardiovascular system includes the heart, the blood and the blood vesicles. The heart is a muscular organ that pumps blood around the body by using blood vessels. The blood vessels consist of the arteries, veins and capillaries. The blood carries dissolved oxygen to the body cells and at the same time, it removes the waste products made by respiration. Blood also distributes heat throughout the body, along hormones, nutrients, salts, enzymes and urea. The heart is a double

Effects of Caffeine on a Person’s Cardiovascular System INTRODUCTION Caffeine is a stimulant that makes a person’s heart beat faster (Nunley 2013). This effect of caffeine is usually seen as a negative one and that it hearts your cardiovascular health overall. A lower heart rate, both resting and post exercise, is said to be better if the rate is lower because it puts you at a lower risk of having a stroke or heart disease (Boyles 2002). Having a lower rate is preferred because it means that

between the respiratory and cardiovascular systems in maintaining the body’s internal balance The respiratory and cardiovascular systems work together to supply oxygen to the body’s cells, remove carbon dioxide and regulate the Ph of the body’s fluids. This system of regulation is called homeostasis. (www.wiki.answers.com, 2013) To understand how both systems interact requires fundamental knowledge of how each system functions independently. The cardiovascular system is made up of blood, the

The cardiovascular system can be broken down into two words 'cardio' or 'cardi' meaning heart and 'vascular' meaning blood vessels Roberts, (2010). The cardiovascular system is also known as the circulatory system Roberts, (2010). The whole meaning cardiovascular system can be explained as a system consisting of the heart, blood vessels, arteries and veins which carry blood around the body and takes oxygen and nutrients to the body tissues and removes wastes products from the tissue cells Roberts

optimal temperature and pressure for the health of cells (Tortora, p.22). The respiratory and cardiovascular systems are able to maintain the first one. Some of the other organs in the body involved with homeostasis are pancreas, kidneys and skin. The respiratory and cardiovascular systems work in conjunction to maintain the body’s internal balance. The cardiovascular system relates to the circulatory system, which consists of the blood, the heart and blood vessels. (Tortora, p.546). The blood carries
