Q.1. Give one example to show that organ systems work in unison. You may mention two or more organ systems to support your point.

The respiratory system, digestive and excretory systems, circulatory and urinary systems, integumentary system, skeletal and muscular systems, endocrine system, lymphatic system, neurological system, and reproductive systems are among the 11 organ systems. Other than organ systems, the human body has other systems. The immune system, for example, defends the body from infection, yet it is not an organ system because it lacks organs. Some organs are found in multiple systems.

Q.2. “Physical activities are  necessary for developing a healthy body and healthy mind.” Give two examples in support of this statement.

• Assume there are two boys who are the same age. One of the boys participates in a variety of sports and physical activity. The other child, on the other hand, is a couch potato who does not engage in any physical activity. Over time, we will undoubtedly notice that the first boy has built a healthy physique while the other lazy boy has gained a significant amount of weight. This example demonstrates the importance of physical activity in maintaining a healthy body.
• On the other side, there are several team games in which we must maintain our composure and cooperate with one another. Regular involvement in such team sports is undoubtedly beneficial to the development of positive mental characteristics.

Q.3. Mention two changes that take place in each of the circulatory and respiratory systems due to regular physical activities.

Wait a few seconds before releasing it. Humans, on average, breathe 15 times a minute while they are not exerting themselves. This works out to around 900 breaths per hour, or 21,600 per day. Water fills the lungs with each inhalation and rushes out with each exhalation. The air in the chest cavity does more than just inflate and deflate the lungs. The oxygen in the air passes into the lungs, reaches the bloodstream, and continues to the organs and tissues. There, oxygen is substituted for carbon dioxide, a waste product of the cell. CO2 leaves the cells and reaches the bloodstream.

Q.4. Ravi is a good athlete. Give one permanent effect of being an atlete on of systems his muscular system, and respiratory system.

Doping is a topic of public, legal, and medical controversy, and it has been linked to a variety of sports in recent years, including athletics, cycling, bodybuilding, soccer, and swimming. The integrity of sports competitions, as well as the safety of drugs and other techniques used to increase athletic strength, are both ethical concerns when it comes to doping. Because drugs on the banned list are easily accessible by medically unregulated means such as the Internet, these issues are gaining in popularity and significance.

Q.5. Complete the sentence:
The respiratory system gets positively affected by undertaking yoga exercises regularly because ______.

The air is brought into close contact with the blood by these tiny air sacs, which have a plentiful blood supply. The trachea, which branches into the two main bronchi in the middle of the chest, is the largest of the airways, or hollow tubes, that connect these air sacs to the outside world. These enter the lungs and branch into a succession of smaller tubes called bronchioles, which branch into secondary and tertiary bronchi that are progressively narrower. The respiratory system consists of organs and tissues that assist in breathing. Your airways, lungs, and blood arteries are all part of it.

Q.6. Some of your friends avoid physical activity. Other friends are always eager to participate in physical activities. Prepare a health profile of your friends who indulge in games and yoga regularly. Indicate what physical activities they undertake regularly. What is the time duration?   How do those who are physically active get the motivation to play some games or exercise regularly? Present your findings in class and allow your peers in the classroom to add to the profiles you prepared.

Food is digested and processed in the digestive system into a shape that can be broken down in the cell to release energy. The respiratory system ensures that each and every cell in the body has a constant supply of oxygen for food oxidation. It's also in charge of removing the carbon dioxide that's formed as a result of the oxidation.

• When you have a workout buddy, particularly a friend, you're less likely to get bored. You're getting better as you're catching up, laughing, and supporting each other. It's a win-win situation.
• During exercise and breaks, chatting with a friend can also help pass the time. You'll also have more choices, such as playing tennis or squash.
