We all know that the main functions of the blood are the transport of respiratory gases, digested food or nutrients, waste products, hormones, enzymes and ions from one body part to another, it protects a body against diseases and regulates body temperature. In other words, blood is the essence of life. A body cannot survive without a sufficient amount of blood. Unfortunately, there are people who don’t have the same chances as we do. Let us take the United States as example. Every two…

The terms heart disease and cardiovascular disease are interchangeable. “Cardiovascular disease is caused by narrowed, blocked or stiffened blood vessels that prevent your heart, brain or other parts of your body from receiving enough blood”(“Diseases”). Heart disease kills by suffocating a body from the inside. Heart disease causes “36 percent” of deaths in America(“Top”). An abstract example of heart…

During my dialysis experience I found it to be very informative and interesting. We were not allowed to touch the patients or help with any care but the staff was interactive and explained was they were doing. The staff also was able to provided scenarios of different complications that happened and how they 'd respond. By the end of the first day I was able to see what the caregiver would due if a patient had muscle cramps, was short of breath and had chest pain. The first day I mostly…

nutrients, hormones and cellular waste products and permits blood to circulate and form cells in the body to nourish it with every heartbeat throughout the body.However, the Cardiovascular system is composed of the following organs, heart and blood vessels, including arteries, veins, and capillaries. One of the major structures of this system is the heart which functions to propel blood throughout the body, supplying oxygen and nutrients to the tissues. For example, the right side of the heart…

Vascular smooth muscle cells (VSMC) and extracellular matrix (ECM): Blood vessels, include arteries that transport blood from the heart to the systemic circulation, and veins that transport blood back again into the heart. A remarkable change in blood vessel structure and function happened, with the emergence of a high-pressure, pulsatile circulatory system in vertebrates. Blood vessels then evolved from simple tubes for channeling blood or other body fluids from a low-pressure heart. According…

Body systems and the bond types of Vitamins and Minerals go hand in hand. The Digestive System breaks down food into vitamins and minerals to be transported to other body systems. The Integumentary System is made up of skin, which uses copper to create Melanin to help protect against the sun. The Integumentary System also uses Vitamins A and C, as well as Niacin and Zinc for healthy growth and repair of skin. The Respiratory System consists of mouth, nose and lungs to inhale oxygen and exhale…

The spleen can be found in the left upper quadrant of the abdomen, lying posteriorly to the stomach and underneath the diaphragm. The spleen can be found enclosed in a capsule of dense irregular connective tissue (Krause, 2008). Prone to infections and other conditions, the spleen can easily become enlarged because it is highly vascularized. Malignancies, parasites, liver diseases and other conditions passed in the blood and immune system can cause the spleen to be infected. In addition to the…

Worksheet 1: Biological Hierarchy; and Organising the Natural World 1. Define what is meant by the “biological hierarchy”. Biological hierarchy is the structured organisation of all biological entities. It can be shown in pyramid form with the most simple element at the base being atoms and at the pinnacle is the ecosphere, the most complex. 2. What is an “emergent property?” An emergent property is when a new property develops on the next step in the biological hierarchy as the levels…

When varicose veins are very close to the surface of the sin, they may spontaneously rupture and bleed. A minor injury to the skin can also make them bleed, usually in the veins near the ankle. These may not cause any weakness or pain. When pressure builds up in varicose veins near the ankle or foot, the pressure may be as strong as arterial blood pressure. This is because of gravity along with the pressure of blood that pools in the veins. The vein may rupture and bleed into the surrounding…

physiologic process important to mechanisms like wound healing, menstruation, tissue growth and embryonic development (Griffioen & Molema, 2000). Endothelial cells which line the blood vessels are in direct contact with blood. Below the layer of endothelial cells, the pericytes (structural support cells) surround the blood vessels along with fibroblasts, smooth muscle cells, extracellular membrane and basement membrane (Griffioen & Molema, 2000). Endothelial cells play a role in many regulatory…
