more oxygen. The pump on the left hand side receives oxygenated blood and then pumps it into the arteries to deliver its oxygen around the body. The deoxygenated blood enters the top right chamber of the heart‚ named the right atrium‚ through two veins. Blood from the upper portion of the body‚ like the head and arms‚ flows in through the superior vena cava. Blood from the lower body‚ which are the legs‚ comes in by the inferior vena cava. The blood that is in need of oxygen is forced to leave the

Introduction Cardiovascular Dynamics and the Cardiovascular Physiology experiments both have multiple goals. The first experiment aims to understand how blood flow‚ pressure gradient‚ and resistance relate to one another. To understand this‚ resistance and contributing factors‚ such as vessel radius‚ viscosity‚ and vessel length must be studied. The effects of vessel radius and stroke volume on the ventricular pump should also examined. The experiment also calls for an understanding of cardiovascular

more dimensions and features and is not as flat as were taught at a young age. The heart a muscular organ about the size of a fist‚ located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The heart has four chambers; the left and right atrium‚ left and right ventricle and the coronary Arteries that run along the surface of the heart and provide oxygen-rich blood to the heart muscle (The Heart 2014)

Fantastic Voyage – Battle of the Lung Gabrielle Jackson HS130-04 Unit 4 Assignment Kaplan University February 19‚ 2013 Today we will be taking a journey through the human body. We will be injected into the femoral vein of a healthy‚ 28 year old female named Corrin. We have received previous alert that there is a bacterium invading Corrin’s lower lobe of her left lung. As we go on this special voyage‚ we will get to document this invasion in regards to how infections attack the human body

cells and tissues. Waste substances flow from the tissues and cells into the blood for disposal. The capillaries join and enlarge to create tubes that eventually become veins‚ which take blood back to the heart. Vessels carrying oxygenated blood (usually arteries) are shown in red and those carrying deoxygenated blood (usually veins) are blue. The cardiac muscle of the heart wall depends on a constant flow of blood supply by the coronary arteries. Coronary arteries are blood vessels that arise from

The cardiovascular system is a closed organ system that is found within humans and other vertebrates. The heart consists of the right and left ventricle‚ right and left atrium‚ aorta‚ capillaries‚ pulmonary arteries and veins and the anterior and posterior vena cava. All of the following structures maintain the heart’s beating cycle and the circulation of blood throughout the body. Three main types of blood vessels: Arteries - Thick-walled tubes in which blood is brought from the heart to various

lymphatic system‚ the muscular –skeletal system and lastly the endocrine system. Each of these systems has their own functions and purpose Cardiovascular System- The cardiovascular system is made up of the heart‚ blood vessels‚ arteries‚ capillaries and veins. The cardiovascular system makes up a network which helps to deliver blood to all the tissues in our body. Each heartbeat pumps blood around our body‚ carrying necessary nutrients needed for our body to be absorbed and oxygen to the cells within our

Smooth muscle- are involuntary muscles found in the walls of hollow organs like the stomach‚ intestines or bladder. Smooth Muscles have many functions in the body‚ but one of the functions of smooth muscles in the bladder contracts to push urine out of the body. Skeletal muscle- Skeletal Muscles are muscles attached to the skeleton. The skeletal muscles main function is to contract to support the skeleton in movement. Skeletal muscles are voluntary because we have complete control of the movements

to give medicine or nutrition through a person’s veins. The tip of the central line ends in a large vein (vena cava) just above the person’s heart. Medicine given through the central line is quickly mixed with blood because the blood flow within this large vein is so great. This dilutes the medicine so it is swiftly delivered throughout the body. A central line may be placed because: You need medicine that would be irritating to the small veins in your hands or arms. You need long-term IV

08/12/13 1. MEDICAL TERMINOLOGY Aneurysm (AN-ū-rizm) A thin‚ weakened section of the wall of an artery or a vein that bulges outward‚ forming a balloonlike sac. Common causes are atherosclerosis‚ syphilis‚ congenital blood vessel defects‚ and trauma. If untreated‚ the aneurysm enlarges and the blood vessel wall becomes so thin that it bursts. The result is massive hemorrhage with shock‚ severe pain‚ stroke‚ or death. Treatment may involve surgery in which the weakened area of the blood
