Question: Differentiate the following with respect to x: $\sin x \sin 2 x$ Solution: To Find: Differentiation NOTE : When 2 functions are in the product then we used product rule i.e $\frac{d(u, v)}{d x}=v \frac{d u}{d x}+u \frac{d v}{d x}$ Let us take y = sin x sin 2x So, by using the above formula, we have $\frac{d}{d x}(\sin x \sin 2 x)=\sin x \frac{d(\sin 2 x)}{d x}+\sin 2 x \frac{d(\sin x)}{d x}=\sin x(2 \cos 2 x)+\sin 2 x(\sin x)=$ $2 \sin (x) \cos (2 x)+\sin 2 x(\sin x)$ Differentiation o...

Question: What is the significance of the hepatic portal system in the circulatory system? Solution: The hepatic portal system directs deoxygenated blood from the parts of the gastrointestinal tract to the liver and finally taking it to the heart. This provides the liver with metabolic substrates....
Read More →Explain the advantage of the complete partition
Question: Explain the advantage of the complete partition of ventricle among birds and mammals and hence leading to double circulation. Solution: In birds and animals, the two ventricles are separated by the inter-ventricular septum. Oxygenated blood received by the left atria passes to the left ventricle and Deoxygenated blood received by the right atria passes to the right ventricle without getting mixed. Deoxygenated and oxygenated blood remains separated and do not mix....

Question: Briefly describe the followings: a. Anaemia b. Angina Pectoris c. Atherosclerosis d. Hypertension e. Heart failure f. Erythroblastosis foetal Solution: a. Anaemia is a disorder that occurs due to the lesser count of RBC or a reduced amount of haemoglobin than the normal value. b. Angina Pectoris is caused when adequate oxygen does not reach the heart muscles leading to chest pain and discomfort. c. Atherosclerosis is the cause of disease when the fat takes place at the walls of the art...

Question: Differentiate between a. Blood and Lymph b. Basophils and Eosinophils c. Tricuspid and bicuspid valve Solution: a. Blood is a part of our circulatory system which is red due to the presence of haemoglobin whereas lymph is a part of our lymphatic system which is colourless due to the absence of haemoglobin. b. Basophils are bean-shaped nucleus stained with basic dye whereas the eosinophil is two-lobed nuclei which are stained with acidic dyes. c. The tricuspid valve is formed by three f...

Question: Evaluate the following integrals: $\int x^{3} \cos x^{4} d x$ Solution: Assume $x^{4}=t$ $d\left(x^{4}\right)=d t$ $4 x^{3} d x=d t$ $x^{3} d x=\frac{d t}{4}$ Substituting $t$ and $d t$ $\Rightarrow \int \frac{1}{4} \cos t d t$ $\Rightarrow \frac{1 \sin t}{4}+c$ But $t=x^{4}$ $\Rightarrow \frac{1}{4} \sin x^{4}+c$...
Read More →The walls of ventricles are much
Question: The walls of ventricles are much thicker than atria. Explain. Solution: Ventricles function as a pumping agent of blood to all organs so that they have to exert more pressure. The atria receive blood so they have fewer loads to take, hence thinner walls....

Question: Differentiate the following with respect to x: $\cos 3 x \sin 5 x$ Solution: To Find: Differentiation NOTE : When 2 functions are in the product then we used product rule i.e $\frac{\mathrm{d}(\mathrm{u} \cdot \mathrm{v})}{\mathrm{dx}}=\mathrm{V} \frac{\mathrm{du}}{\mathrm{dx}}+\mathrm{u} \frac{\mathrm{dv}}{\mathrm{dx}}$ Let us take y = cos 3x sin 5x So, by using the above formula, we have $\frac{d}{d x}(\cos 3 x \sin 5 x)=\sin 5 x \frac{d(\cos 3 x)}{d x}+\cos 3 x \frac{d(\sin 5 x)}{d ...

Question: How will you interpret an electrocardiogram (ECG) in which time taken in the QRS complex is higher? Solution: The normal duration of the QRS complex is less than or equal to 0.10 seconds. If the QRS complex is longer than 0.10 seconds and the wave is enlarged it indicates the person is having Myocardial Infarction or Heart Attack....
Read More →What is the significance of the time gap in the passage
Question: What is the significance of the time gap in the passage of action potential from the sino-atrial node to the ventricle? Solution: It allows relaxation to the ventricles. This causes ventricular pressure to fall leading to the closure of semilunar valves which prevents the backflow of blood into the ventricles....
