The arteries always take out blood from the heart.Most arteries carry oxygenated (oxygen-rich) blood from the heart to the rest of the body.3VeinVeins differ from HYPERLINK http//www.wikipedia.org/wiki/Artery o Artery arteries in structure and function for example‚ arteries are more muscular than veins‚ veins contain valves.Most veins carry deoxygenated (containing less oxygen and more carbon dioxide and other

the heart‚ arteries‚ capillaries and veins. As blood begins to circulate‚ it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for the cells in the brain and the body to do their work. The oxygen rich blood travels throughout the body in its system of arteries into the smallest arterioles. On its way back to the heart‚ the blood travels through a system of veins. As it reaches

through the Superior Vena Cava which is the large vein at the top of the heart‚ and the Inferior Vena Cava‚ which is the large vein at the bottom of the heart. Blood flows into the right atrium‚ passes through the tricuspid valve‚ and makes its way into the right ventricle. It then moves through the pulmonic valve‚ into the pulmonary artery to the lungs.” After picking up oxygen in the lungs‚ the blood moves out of the lungs into the pulmonary vein‚ into the left atrium‚ through the mitral valve‚

elasticity. State why each of these properties is necessary for muscle function. a. Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces more than a local effect- The local electrical change triggers a wave of excitation that travels

Blood Clots What are blood clots? Blood is a liquid that flows within blood vessels. It is constantly in motion as the heart pumps blood through arteries to the different organs and cells of the body. The blood is returned back to the heart by the veins. Veins are squeezed when muscles in the body contract and push the blood back to the heart. Blood clotting is an important mechanism to help the body repair injured blood vessels. Blood consists of: · red blood cells containing hemoglobin that

Due to his mitral valve prolapse‚ blood can back up into the left atrium and eventually into the pulmonary veins. The backing up of blood into the lungs causes increased pressure buildup in the blood vessels of the lungs‚ causing fluid to be released into the lung tissue. This leads to pulmonary edema. Pulmonary edema causes shortness of breath because the excess

They also remove the waste products of metabolism‚ for example: the final products from the haemoglobin breaking down‚ urea from extra amino acids‚ “creatinine from creatine in muscle and uric acid from nucleic acids” as stated by (Stretch et.al: p174). In addition‚ they remove unnecessary chemicals from the blood‚ for example toxins‚ pesticides‚ drugs and food additives. Last of all‚ they secrete a hormone that manages the production of renin and blood cells. This is known as erythropoietin
