1.2 Know about the structure and function of the cardiorespiratory system

TermDefinition
cardiovascular system The body system that comprises the heart, blood vessels and blood.
heart A muscular organ which pumps blood around the body via the blood vessels. It is made of a special type of muscle (cardiac muscle) that never gets tired and can therefore work continuously.
blood vessels The channels through which blood is circulated. They form a network that covers the entire body.
blood A fluid that delivers vital chemicals, including oxygen, nutrients, and hormones to the body’s organs, and also removes waste products from them.
arteries Blood vessels that carry blood away from the heart, including the delivery of oxygenated blood to all of the body’s other organs.
veins Blood vessels that carry blood towards the heart, including de-oxygenated blood from all of the body’s other organs.
capillaries Small blood vessels that transport blood from arteries to veins. Nutrients, oxygen and waste products are exchanged with the body through the cell walls of these vessels.
delivery of oxygen One function of the cardiovascular system is d..... o..... o..... to the body's cells from the lungs.
removal of carbon dioxide One function of the cardiovascular system is r..... o..... c..... d..... from the body's cells to the lungs.
delivery of nutrients One function of the cardiovascular system is d..... o..... n..... to the body's cells.
removal of waste products. One function of the cardiovascular system is r..... o..... w..... p..... from the body's cells.
regulation of body temperature One function of the cardiovascular system is r..... o..... b..... t..... (also known as thermoregulation).
thermoregulation The maintenance of a stable core body temperature (around 37°C). The cardiovascular system helps to achieve this by decreasing or increasing the blood flow to the body’s extremities.
respiratory system The body system comprising the lungs, the airways through which we breathe, and the muscles that control breathing. Its purpose is to take in oxygen for respiration, and to expel carbon dioxide, which is a waste product of respiration.
inspiration and expiration Breathing in and breathing out, controlled by muscular movement, especially in the diaphragm.
diaphragm A large muscle located below the lungs. It contracts to expand the lungs and draw air inwards (inspiration), and relaxes to force air outwards (expiration).
respiration A chemical process that takes place within all living cells, when energy is released from glucose.
aerobic respiration The type of respiration that takes place when oxygen reacts with glucose, releasing energy. The waste products of this process are carbon dioxide and water.
anaerobic respiration A type of respiration that does not require oxygen. It takes place when not enough oxygen is available to produce the energy needed, for example during short sharp bursts of physical activity. Lactic acid is a waste product of this process..
gaseous exchange A process occurring in the lungs, when oxygen is taken from the air into the blood, and carbon dioxide is expelled from the blood into the air.
diffusion The movement of any substance from an area of high concentration to an area of low concentration. During gaseous exchange, oxygen and carbon dioxide move across capillary cell walls via this process.
alveoli Tiny structures within the lungs which increase the surface area of capillary cell walls available for diffusion in gaseous exchange.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
