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

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)

The first was said to be the continued use of leeches. The second was called arteriotomy‚ which is a process where the arteries in the temples would be ruptured and bled. The third was phlebotomy‚ commonly known back then as “breathing a vein”‚ where a large vein would be cut‚ to draw blood. The last was scarification which is said to be a particularly stomach-tossing method that involved one of a varied set of tools such as spring-loaded lancets and a round‚ mutli-bladed‚ and spring-loaded device

through a wire‚ called a lead. Sometimes just one lead is needed. Other times‚ there will be two leads. There are two types of pacemakers: • Transvenous pacemaker. This type is placed under the skin or muscle of your chest. The lead goes through a vein in the chest area to reach the inside of the heart. • Epicardial pacemaker. This type is placed under the skin or muscle of your chest or belly. The lead goes through your chest to the outside of the

The connectors between the veins and arteries. Very tiny and thin walled like arterioles‚ (their actually buddies) their function is to supply body tissue with the components of blood and to get rid of waste from surrounding cells. They have a specific job‚ unlike most blood vessels‚ which primary job is to transport blood from one station to another continuously. Venules • Venules are minute veins- Meaning real quick. There main job is to drain the capillaries into veins‚ returning the blood to the

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

system. Oxygenated blood is pumped away from the heart to the rest of the body‚ while deoxygenated blood is pumped to the lungs where it is re-oxygenated before returning to the heart. The total blood volume is unevenly distrubted among the arteries‚ veins‚ and capillaries. The heart arteries and capillaries in the pulmonary and systemic circuits normally contain30 percent of blood volume like 1.5 liters of whole blood. And the venous system contains the rest 65-70 percent and that’s about 3.5 liters

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

best to get them situated. Arteriosclerosis‚ Hypertension‚ Aortic Aneurysm‚ Heart Disease‚ Varicose Veins‚ and Chronic Venous Insufficiency‚ Angina‚ and Peripheral Vascular Disease are all problems that can proceed in the cardiovascular system. Arteriosclerosis is a circulatory disease that is caused by fat buildup‚ cholesterol‚ and or other substances in the artery wall. These things make the veins stiffen up and become narrow. Hypertension is an issue when a force of blood pushes against the artery

CVP and its normal waveform1 - 2 : It is a technique used to measure existing pressure at the junction on CVC and the right atrium. To measure the pressure they used the central venous catheter that inserted on right jugular vein. This technique used for evaluation the cardiac function in ill patients. In addition‚ it can used for diagnosis purposes such as heart failure and fluid resuscitation. The relationship between cardiac function and venous return used for determination of heart failure
