The cardiovascular system‚ also known as the circulatory system‚ is composed of the heart‚ blood vessels‚ and blood. The term cardiovascular refers to the heart (cardio-) and blood vessels (vascular). The term circulatory refers to the circulation of the blood. The heart is a muscular pump and its regular contractions send blood into tough‚ elastic tubes called arteries‚ which branch into smaller vessels and convey oxygen-rich blood through the body. The arteries eventually divide into tiny capillaries

Osteoporosis Anatomy & Physiology 250 CASE - Module 2 Osteoporosis is a condition of low bone density that can progress silently over a long period of time. Osteoporosis has no symptoms until a fracture occurs‚ which causes bone pain‚ height loss‚ and abnormal spine curvature. If a fracture is determined to be due to osteoporosis‚ it is considered a pathological fracture‚ which is a break of a diseased or weakened bone without any identifiable trauma or following a minor injury that would

Cardiovascular system consists of the heart which pumping and transporting blood to the body through blood vessels which is the other part of the cardiovascular system. The blood vessels consist of veins‚ capillaries‚ and arteries. Each one of the blood vessels has a specific function such as arteries which transfer the blood from the heart to the whole body‚ and veins which have the reverse process which carries the blood back to the heart. This is a simple definition of cardiovascular system. Then

This essay will explain the function of the respiratory‚ digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food

ANATOMY & PHYSIOLOGY of the EYE Even though the eye is small‚ only about 1 inch in diameter‚ it serves a very important function -- the sense of sight. Vision is by far the most used of the five senses and is one of the primary means that we use to gather information from our surroundings. More than 75% of the information we receive about the world around us consists of visual information. The eye is often compared to a camera. Each gathers light and then transforms that light into a "picture

The epidermis which is the outer layer and is a protective multi-layered self-renewing structure which varies in thickness depending on which part of the body it covers. The dermis is underneath the epidermis‚ this is a layer of connective tissue which provides the

Introduction In the United States‚ Cardiovascular Disease (CVD) remains the greatest common cause of death. Cardiovascular Diseases‚ also known as the common heart diseases‚ are any conditions that involve blocked blood vessels that can lead to either a heart attack or other heart problems. The common types of CVD are coronary artery disease‚ high blood pressure‚ stroke‚ and arrhythmia. CVD is a major disease that will not show any symptoms until the disease is at its extreme. Yet numerous adults
