Describe the structure and function of human heart |
| Answer» StructureThe heart consists of four chambers, right and left atria above right and left ventricles. The functions of each part are as follows.• The right atrium links to the right ventricle by the tricuspid valve. This valve prevents backflow of the blood into the atrium above, when the ventricle contracts.• The left atrium links to the left ventricle by the bicuspid valve (mitral valve). This also prevents backflow of the blood into the atrium above. • The chordae tendonae attach each ventricle to its atrioventricular valve. Contractions of the ventricles have a tendency to force these valves up into the atria. Backflow of blood would be dangerous, so the chordae tendonae hold each valve firmly to prevent this from occurring.• Semi-lunar (pocket) valves are found in the blood vessels leaving the heart (pulmonary artery and aorta). They only allow exit of blood from the heart through these vessels following ventricular contractions. Elastic recoil of these arteries and relaxation of the ventricles closes each semi-lunar valve.• Ventricles have thicker muscular walls than atria. When each atrium contracts it only needs to propel the blood a short distance into each ventricle.• The left ventricle has even thicker muscular walls than the right ventricle. The left ventricle needs a more powerful contraction to propel blood to the systemic circulation (all of the body apart from the lungs). The right ventricle propels blood to the nearby lungs. The contraction does not need to be so powerful. If blood moved in the wrong direction, then transport of important substances would be impeded. | |

What is wright hand thumb rule how to use it and where |
| Answer» Ur answer is as follows ::RIGHT HAND THUMB RULE :If we imagine the current conductor to be held on that thumb points in the direction of current then the direction in which the figures encircle, represents the direction of magnetic lines of force. It is used to find magnetic field with the help of current. In this you should always be given the current and you should have to find magnetic field. To use this method :you have to put your thumb toward that direction where current is given. and by putting your your thumb in the direction of current you mark the direction of magnetic field....... What is magnetic field? The direction in which your hands get folded. That direction is called the magnetic field that means that the direction of hands is called the magnetic field.Hope this will help U a lot Thanks! | |

Which acidic oxides are responsible for the acid rain |
|
Answer» H2SO4 & HNO3 are acid acidin oxides are SO2 and NO2 Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Sulphuric acid Nitric acid |

What do you mean by chemical equation |
|
Answer» The representation of chemical reaction in the form of formula and symbols It is short hand representation of elements or compound Chemical equation is a method of representing chemical reaction by using symbols and formula of the substances involved in it is called chemical reaction. The symbolic representation of a chemical reaction is called a chemical equation. In the chemical equation reactants are written on the left hand side with a plus sign between them. And the products are written on the right hand side with a plus sign between them. An arrow separates the reactants from the products. The arrow head points towards the products and indicates the direction of the reaction. Symbolic representation of chemical reactions is called chemical reactions |
