NCERT Solutions for Class 7 Science Chapter 10: Respiration in Organisms
Respiration is crucial for survival as all living organisms breathe in air to get energy from food. The number of times a person breathes in a minute is called as the breathing rate. On an average, an adult human being at rest breathes in and out 15–18 times in a minute. This number increases during heavy exercise. Find out more about the process of respiration in humans through this chapter.
Animals like cows, buffalos, dogs, and cats have the same respiratory organs and the process of breathing is similar to those in humans. While earthworms exchange gases through its moist skin.

NCERT Solutions for Class 7 Science Chapter 11: Transportation in Animals and Plants
Followed by Repirstaion in Organisms, this chapter will deal with the transportation of food and oxygen in various animals and plants. In most animals, the blood circulates food and oxygen to different cells of the body. It also carries waste products to different parts of the body for excretion. The circulatory system consists of the heart and blood vessels.
In humans, blood flows through arteries and veins and the heart acts as a pumping organ. An adult heart beats about 70-80 times per minute to circulate the food and oxygen. During this, the waste products of the body are removed through a process called excretion. Two kidneys, two ureters, a urinary bladder, and urethra are the body parts involved in the excretory system. Through this Transportation in Animals and Plants chapter, you will learn more in detail about blood vessels, capillaries, haemoglobin, heartbeat, kidneys, phloem, plasma, dialysis, excretory system, urinary bladder, etc.
