Double circulation refers to the circulation of blood through two separate pathways: pulmonary circulation and systemic circulation. The heart plays a central role in pumping blood through these pathways. I’ll describe the process of double circulation step by step.
1. Deoxygenated Blood Enters Right Atrium: Deoxygenated blood from the body returns to the right atrium of the heart through the superior and inferior vena cava.
2. Right Atrium Contracts: The right atrium contracts, pushing blood through the tricuspid valve into the right ventricle.
3.Right Ventricle Contracts: The right ventricle contracts, forcing the deoxygenated blood through the pulmonary valve into the pulmonary artery.
4. Pulmonary Circulation: Deoxygenated blood travels through the pulmonary artery to the lungs. In the lungs, carbon dioxide is exchanged for oxygen through the process of pulmonary gas exchange.
5. Oxygenated Blood Returns to Left Atrium: Oxygenated blood returns to the heart through the pulmonary veins, entering the left atrium.
6. Left Atrium Contracts: The left atrium contracts, pushing blood through the bicuspid (mitral) valve into the left ventricle.
7. Left Ventricle Contracts: The left ventricle contracts, sending oxygenated blood through the aortic valve into the aorta.
8. Systemic Circulation: Oxygenated blood is distributed throughout the body through the network of arteries. Oxygen is delivered to tissues, and carbon dioxide is picked up from them.
9. Deoxygenated Blood Returns to Right Atrium: Deoxygenated blood, now carrying carbon dioxide, returns to the right atrium, and the cycle begins again.
Remember, this is a simplified representation, and in a flowchart, each step would be represented by a box with arrows indicating the flow. Additionally, valves play a crucial role in ensuring the one-way flow of blood. Diagram:

a) Noopur is suffering from myopia, also known as nearsightedness. In myopia, distant objects appear blurry, while close objects can be seen more clearly.
b) For myopia correction, a concave lens is needed. The power of the lens is given as -4.5D. The negative sign indicates that it is a concave lens. The focal length (f) of the lens can be calculated using the formula:
f= (-1)/4.5= -0.22 cm,as concave lens.
c) Defective Eye (Myopia):
Parallel rays from a distant object converge in front of the retina, causing a blurry image.The image formed is in front of the retina.
Correction with Concave Lens: Parallel rays are diverged by the concave lens.
The diverged rays appear to come from a virtual focus point, resulting in the formation of a clear image on the retina.
Please note that drawing accurate ray diagrams requires specific measurements and angles, but a basic representation can be made to illustrate the concept.
d) Causes of Myopia:
Eyeball Shape: Myopia is often associated with an elongated eyeball, where the distance from the cornea to the retina is too long. And secondly, Due to excess curvature of eye lens.
Genetics: Family history plays a significant role, and individuals with myopic parents are more likely to develop myopia.
Environmental Factors: Excessive near work, such as reading or using digital devices for extended periods, can contribute to the development and progression of myopia.
It’s important for Noopur to consult an eye care professional for a comprehensive eye examination to determine the exact prescription and appropriate corrective measures. Regular eye check-ups are recommended for the timely detection and management of vision-related issues.

Both overproduction and underproduction of growth hormone (GH) can lead to disorders in the body, impacting growth, development, and various physiological functions. Growth hormone is produced by the pituitary gland, a small gland located at the base of the brain. Here’s an explanation of the disorders associated with both overproduction (hypersecretion) and underproduction (hyposecretion) of growth hormone:
A) Overproduction of Growth Hormone (Hypersecretion):
Condition: The overproduction of growth hormone is often associated with a medical condition called acromegaly in adults or gigantism in children.
Causes: Hypersecretion of growth hormone is commonly caused by a noncancerous tumor (adenoma) in the pituitary gland, which leads to excessive GH production.
Effects: In children (gigantism): Excessive GH before the closure of the growth plates in bones can result in abnormal and excessive growth, leading to abnormally tall stature.
In adults (acromegaly): Excess GH after the closure of the growth plates can cause the thickening of bones and tissues, leading to enlarged hands, feet, and facial features. It can also affect internal organs and metabolism.
B) Underproduction of Growth Hormone (Hyposecretion):
Condition: The underproduction of growth hormone results in a condition known as growth hormone deficiency (GHD).
Causes: Hyposecretion can be caused by congenital factors, damage to the pituitary gland, genetic factors, or certain medical conditions.
Effects: In children: Growth hormone deficiency can lead to stunted growth and short stature if not treated. Children with GHD may have delayed physical development.
In adults: Growth hormone deficiency can result in decreased bone density, decreased muscle mass, increased body fat, and changes in overall body composition.
In both cases, the imbalances in growth hormone levels can impact not only the growth and development of bones and tissues but also various metabolic processes in the body. Treatment approaches may include hormone replacement therapy to restore normal growth hormone levels or surgical intervention to address the underlying causes, such as the removal of a pituitary tumor in cases of hypersecretion. Regular monitoring and medical management are essential to mitigate the effects of these disorders and ensure overall health and well-being.

a) AIDS (Acquired Immunodeficiency Syndrome) belongs to the category of viral diseases. The causative organism of AIDS is HIV (Human Immunodeficiency Virus). HIV attacks the immune system, specifically CD4 cells (T cells), which help the immune system fight off infections.
b) The government, by conducting programs related to AIDS prevention, testing, and treatment, is trying to develop public health awareness and promote values related to public health and well-being. The key values being emphasized include:
1) Health Consciousness: Encouraging citizens to be aware of their health and take preventive measures against diseases such as AIDS. This involves promoting regular testing, adopting safe practices, and seeking timely medical intervention.
2) Responsibility: Promoting a sense of responsibility for one’s own health and the health of the community. This includes practicing safe behaviors to prevent the spread of HIV and taking steps to get tested and seek treatment if necessary.
3) Empathy and Compassion: Fostering a sense of empathy and compassion for individuals affected by HIV/AIDS. By providing information and support, the government aims to reduce stigma and discrimination associated with the disease.
4) Community Well-being: Highlighting the interconnectedness of individuals within a community and emphasizing the importance of collective efforts to prevent the spread of infectious diseases. This involves promoting a sense of shared responsibility for maintaining a healthy community.
In summary, the government is trying to instill values related to health awareness, responsibility, empathy, and community well-being through its campaigns on AIDS prevention and treatment.

1. pH are sensitive for Plants and animals. Living beings can survive only in narrow or small range of pH change.
2. pH of the soil. Plants require a specific pH range for their healthy growth.
3. pH in our digestive system. In digestive system, during digestion the stomach produces too much acid that cause irritation and pain. But remember, our stomach produces hydrochloric acid (HCL) that helps in the digestion of food also.
4. pH is also acts as self-defense by plants and animals through chemical warfare agents. Sting of Bees, leaves some residue and acid causing irritation and pain. Applying a mild base like (baking soda, apple cider vinegar) on the area of stung, provides relief from pain and swelling.
5. pH that responsible for tooth decay. When the pH of the mouth is lower than 5.5 tooth are going to start to decay. And, when pH in the mouth is below 5.5, tooth enamel gets corroded.
