Level 3 |
I know that oxygen is required for aerobic respiration and that oxygen and glucose are transported in the blood. I can describe differences between inhaled and exhaled air. I can name and identify the position of heart and lungs on a body outline. I know that humans breathe and how and why during exercise breathing changes. |
|
Level 4 |
I can describe differences between inhaled and exhaled air % of gases in and out during breathing. I can explain simply how the heart and lungs work together to enable oxygen, food and waste to be transported to different places in the body. I can label and position on a simple diagram/model parts of breathing system, such as trachea (wind pipe), bronchioles, diaphragm. |
|
Level 5 |
I can describe the role of blood in transporting carbon dioxide from, and oxygen to, the lungs and explain why tissues need a good blood supply. I can describe aerobic respiration as a reaction with oxygen and some effects of an inadequate oxygen supply. I can describe and explain differences between inhaled and exhaled air and identify similarities in aerobic respiration in plants and animals. I can understand the ways in which parts of the mammalian breathing system works, linked to gas exchange between the lungs and the blood system. |
|
Level 6 |
I know human respiration is aerobic (involves oxygen). I can represent the process of aerobic respiration as a word equation. I can compare aerobic and burning fuels. I can distinguish between breathing (external respiration) and internal respiration in cells. |
|
Level 7 |
I can represent the process of aerobic respiration as a symbol equation and explain the underlying chemical change involved. I can describe the features of alveoli and explain how damaged alveoli result in less gas exchange. I can describe how the breathing system is adapted to its function. I can understand chemical change involved in aerobic respiration and can link this with nutrition. I appreciate that some cells are adapted to their function. |
