Answer 1

Answer:

1. The respiration rate is the number of breaths a person takes per minute. The rate is usually measured when a person is at rest and simply involves counting the number of breaths for one minute by counting how many times the chest rises.

2. The process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

3.The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.

4. Breathing out is known as exalation.

5. Breathing in is known as inhalation.

6. Gills are the organs that help fish to breathe underwater. They are located on the backside of the eyes. Gills enable fish to absorb dissolved oxygen from water.

7. Spiracles are basically openings or tiny pores located in different parts of some animals. Insects' bodies are covered with holes called spiracles. Once the oxygen enters these holes, it reaches the trachea helping to circulate throughout the body.

8. Trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs. ... When you inhale, air travels from your nose, through your larynx, and down your windpipe. The windpipe splits into two bronchi that enter your lungs.

9.The ribs are the bony framework of the thoracic cavity. The ribs form the main structure of the thoracic cage protecting the thoracic organs.

Answer 2

Q1)The respiratory rate is the rate at which breathing occurs. This is usually measured in breaths per minute and is set and controlled by the respiratory centre.

Q2)Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Q3)The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily.

Q4)We refer to exhalation as 'breathing out'.

Q5)Inhalation is the process or act of breathing in, taking air and sometimes other substances into your lungs.

Q6)Gills are the organs that help fish to breathe underwater. They are located on the backside of the eyes. Gills enable fish to absorb dissolved oxygen from water.

Q7)Spiracles are basically openings or tiny pores located in different parts of some animals. Insects' bodies are covered with holes called spiracles.

Q8)The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people.

Q9)The ribs are the bony framework of the thoracic cavity.
