to the tissue beds of the body. The blood then returns to the heart from the body through the systemic veins. It returns to the right atrium‚ and is pumped to the right ventricle. From the right ventricle the blood is pumped through the pulmonary arteries to the lungs‚ where gas exchange occurs. The blood is returned to the heart through the pulmonary veins to the left atrium. Then it is pumped to the left ventricle to complete the circuit (1‚ 2). The pressure at which the heart pumps blood throughout

Low-density lipoproteins (LDL) are lipoproteins that transport lipids from the liver to alternative tissues like muscle and fat and they contain a large proportion of cholesterol. High-density lipoproteins (HDL) are lipoproteins that pick up and return cholesterol from the tissues and carry it away to the liver for dismantlement and disposal. HDL contain a large portion of protein. Both low-density lipoprotein (LDL) and high-density lipoprotein (HDL) carry lipids within the blood. However‚ low-density

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

Pacemaker The human heart is an essential organ of the human body. Its sole purpose is to supply the body with oxygen by pumping blood through a complex system of veins and arteries. However‚ it is often common for the human heart to suffer from various heart conditions‚ such as a heart block‚ slow heart beat‚ heart attack or heart failure. Such heart conditions can lead to weakness‚ fainting‚ shortness of breath‚ or even possibly death. These can usually be treated with medication but in cases

heart is simple a pump which forces the blood around our bodies through the pipe work we call our arteries and veins. We can measure this force on our vascular system by measuring our blood pressure. Blood pressure is measured in millimeters of mercury (mmHg) and it is recorded as two figures. Normal blood pressure is normally around 120/80. When the heart beats (pumps) the pressure in our arteries increases‚ this is the top figure our Systolic pressure. When the heart isn’t beating (resting in-between
