The correct answer is C.
Cardiorespiratory fitness is a medical term used to describe the capacity of an athlete's body to transfer the necessary oxygen to the muscles and the capacity of the muscles to absorb this oxygen. There are various ways to assess the cardiorespiratory fitness of an athlete, such as the VO2max testing, the Bruce protocol treadmill test, and the beep or bleep test. The more appropriate way to assess the cardiorespiratory fitness is to use a combination of tests since this will give a complete image of the body's fitness level.
Breathing starts at the nose and mouth. You inhale air into your nose or mouth, and it travels down the back of your throat and into your windpipe, or trachea. Your trachea then divides into air passages called bronchial tubes.
For your lungs to perform their best, these airways need to be open during inhalation and exhalation and free from inflammation or swelling and excess or abnormal amounts of mucus.
The LungsAs the bronchial tubes pass through the lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has over 300 million alveoli.
The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from the inhaled air passes through the alveoli walls and into the blood.
After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs.
As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs, where it is removed from the body when you exhale.
Innate immunity: Immunity that is naturally present and is not due to prior sensitization to an antigen from, for example, an infection or vaccination. Since it is not stimulated by specific antigens, innate immunity is generally nonspecific. It is in contrast to acquired immunity. Also called natural immunity.
