The board exam for class 10 comes with a lot of requirement for thorough requirement on the part of students. In addition to completing the theoretical and practical aspects of more subjects than the fingers can count, every subject comes with some other demands. For some subjects, it’s to memorize a lot of formulae while for others it’s inevitable to learn a lot of diagrams.
This stands particularly true in the case of Science subjects which need diagrams ranging from the laboratory instruments in Chemistry, the ray diagrams in Physics and various aspects of human and plant life in Biology. A very common question that has been asked on several occasions by the Board is to draw or label parts of the human heart.
Not everyone is an artist so some class 10 board exam aspirants must be dealing with a lot of trouble for their diagrams. Well, you are in the right place as this article will help you find the easy and fast way to draw the human heart correctly.
But first, let us look at some other details related to biology for class 10.
What are the things to keep in mind while preparing for class 10 Biology?
Biology is one such subject that needs a lot of details to be remembered and as a result, it is time-consuming. As an outcome of that, it may even become boring. The key here is to find out interesting ways to finish the syllabus in the most comfortable way. Some tricks and tips will surely do you good. But before you begin, take a detailed look at the syllabus for class 10 Biology board exams:
- CBSE has its syllabus designed in a way that all units of Physics, Chemistry and Biology come under the category of the Science syllabus.
A brief but detailed Biology syllabus forming unit 2 of Science looks like:
Unit 2: World of Living
- Life processes: ‘Living Being’. The basic concept of nutrition, respiration, transport and excretion in plants and animals.
- Reproduction: Reproduction in animals and plants (asexual and sexual) reproductive health-need and methods of family planning. Safe sex vs HIV/AIDS. Childbearing and women’s health.
- Heredity and Evolution: Heredity; Mendel’s contribution- Laws for inheritance of traits: Sex determination: brief introduction;
So under life processes, as you study the different human organs functioning in their own ways, the human heart comes and occupies a major probability of being asked in the paper.
- Apart from that, to score well in Science, it would also be necessary to score equally well in Physics and Chemistry.
- Since Biology demands more time, you must start it beforehand so as to have more time for practice and revision.
- All tips and tricks will work only when you have the entire syllabus covered and revised.
Let us now take a look at the steps that will guide you to a simple and easy diagram of the human heart.
What are the steps to draw the human heart?
If you take a look at the previous year’s papers of CBSE class 10 Science, you will find that the diagram of the human heart is a favourite of the question paper setters. So it is wise to have a comfortable hold and understanding of the topic with the diagram.
The steps are as follows:
- On a piece of paper, Start drawing the pulmonary veins that go to the lower left of the Aorta. They will be two in number with the top vein being slightly smaller than the bottom vein.
- Below the pulmonary veins, a bit towards the to the right, draw the bottom of the inferior vena cava.
- Next, start drawing the base of the heart, with the right and left ventricles, the right and left atriums. The pulmonary veins will be adjacent to the right atrium, and the inferior vena cava will be adjacent to the right atrium and right ventricle on your diagram.
- You can make a few changes to the diagram as per your convenience of drawing. But make sure the labelling is done properly and all the parts are drawn in the proper place.
You do not need a beautiful diagram to score full marks, just a basic diagram with the correct labels will be more than enough. So follow these steps and understand your concepts, you will be good to go!
