Exercise or any other physical activity, increases the oxygen demand in the lungs and affects the flow of air into the lungs.
Tidal Volume: The amount of air inspired (air that leaves or enters the lungs) during breathing is called tidal volume. With the increase in physical activity such as exercise, the tidal volume increases to allow more gaseous exchange. During exercise, the amount of air to be inhaled increases, thus the tidal volume also increases.
Alveolar Ventilation: It is also known as alveolar volume. It is the amount of air that enters the alveoli in one minute. Alveolar ventilation also increases with the increase in the vital volume due to exercise. This is because oxygen demand increases during exercise.
Anatomical Dead Space: It refers to the air that is directed towards the alveoli but does not participate in the gaseous exchange It decreases during exercise due to increase in ventilation.

Answer: Scientist can determine if an object should be classified as living or non-living cells by looking under a microscope with a slide. If the slide has cells in it, it is considered alive and if the cells contain food, water, exposed waste, and environment, it is alive. If the object or slide does not have any cells in it, it is considered non-living because for a cell to be alive, it needs cells in it.</h3>
Answer:
IT IS BEST FOR A CELL TO HAVE A LARGE SURFACE AREA AND A SMALL VOLUME. THEREFORE, A LARGE SURFACE AREA TO VOLUME RATIO IS MORE DESIRABLE.
Explanation:
The answer is C. anatomy because anatomy is the study of structure while physiology is the study of how the function works either mechanically or etc.
Answer:
Tissues-
Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others.
Cells-
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
