is one of the bodies’ most vital organs‚ without it the body would not receive oxygen and could not survive. The heart is comprised of 4 chambers‚ a left and right atrium and left and right ventricle. The deoxygenated blood enters the heart via a vein into the right atrium where it moves into the right ventricle before being transported to lungs via the pulmonary artery for oxygenation before returning to the heart into the left atrium. From the left atrium the now oxygenated blood

arteries. The plaque builds up in the little passage way in the artery causing the flow of blood to lessen‚ which in turn can cause a heart attack. This plaque can also break off and will cause a blood clot‚ which can stop the flow of blood through the vein. Risk factors such as “smoking‚ diabetes‚ high cholesterol‚ and high blood pressure” (National Heart Lung and Blood Institute‚ page 1) can cause the plaque buildup in the arteries. Other uncontrollable factors such as heredity or environment that can

High or Low Blood Pressure? Purpose: The purpose of this experiment is to compare blood pressure as related to gender and athletic status. Hypothesis: I predict that males have a higher blood pressure than women and athletes have a higher blood pressure than non athletes Background Info: Blood pressure is the amount of force that blood pushes against the inside walls of blood vessels as it passes through. This pressure
Premium Artery Blood Blood pressure
Control of blood pressure The blood pressure measures the force created by the heart beat (blood) on the walls of blood vessels. The blood pressure can show an increase with age due to lack of elasticity and narrowing of arteries. The regulatory centers of cardiac and vasomotor controls the sympathetic neuron to increase the blood pressure with regard to increase in blood volume. These regulating centers are located in the medulla oblongata show vasoconstriction while increasing heart rate. When

our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This process pushes the blood into high pressure arteries to the low pressure veins. Heart rate is most easily measured by counting the pulse of the blood in artery vein in your neck. Motivation/Purpose: It is good to measure heart rate constantly. People are constantly developing heart conditions that aren’t known until it’s too late. Asthma is constantly being developed

Premium Blood Artery Heart
The cardiovascular system is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The blood delivers nutrients and oxygen to the cells in the body. The arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues

This particular system is powered by the heart and relies on the blood in order to transport substances such as oxygen and carbon dioxide around the body through a network of blood vessels including the veins‚ arteries and capillaries‚ the veins and arteries serve the main function of transporting blood throughout the body and arteries enabling the substances to through to the cells due to their walls being
