Lynna [10]

Answer:

Explanation:

1- the purpose of blood flow-circulatory system- is to convey  Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries  and capillaries  away from the heart,  to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.

2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied  through the bicuspid valve into the Left.Ventricle.

During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces  the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary  valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.

Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is  forced through the aortic valve  to empty into the aorta into  the systemic circulation,branches of the carotid artery supplies the heart from the aorta.

The Whole cycle continues.

More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.

Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
