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.
The Truck will take more force to stop the truck moving at a speed of 55mph weighing 4000kg has alot more momentum and will require a force equal to its speed and mass to stop it therefore the truck is the most obvious answer hope this helped bud
<span>Python is Highly case sensitive language. We can use > , < , <= , <= , == , != to compare two strings. Python compares string using ASCII value of the characters.
For example name as "MIDHUN" and name1 as "Midhun" . The first two characters from name and name1 ( M and M ) are compared. As they are equal, the second two characters are compared. Since the ASCII values are not equal the result is not equal.</span>
