Q

Arteries, veins & capillaries.

A

Arteries carry blood away from your heart. Veins carry blood back toward your heart. Capillaries, the smallest blood vessels, connect arteries and veins.

Q

Structure and function of RBC

A

trnsports oxygen. 45% of blood, small round and hollow in centre, no nucleus.

17
Q

What is respiration?

A

Process which cells release the energy they need for their life processes.
Occurs in the mitochondria

18
Q

Diffusion

A

An area of high concentration to an area of low concentration, until reaches equilibrium.

19
Q

what is gas exhange

A

Taking in oxygen and getting rid of carbon dioxide, this process takes place in the alveoli.

20
Q

Breathing vs respiration

A

Breathing = physical process which moves air in and out of lungs
Respiration= chemical reaction where cells break down glucose to release energy.

21
Q

Importance of blood

A

-we have five litres of blood, which takes oxygen to our body cells for respiration.
-blood carries waste products such as carbon and dioxide
-transports nutrients from our digestive system and even moves heat to control our temperature.
