A

Absorb

when living cells or blood take in food or oxygen

Absorbs

light energy hits a surface and is converted into heat energy

absorption

what happens when digested food particles pass from the digestive system into the bloodstream.

Accumulate

to build up

Accumulation

the process of building up or gathering together

acidic

has a pH less than 7, for example stomach acid.

Adaptations

changes to organisms which allow them to survive or to do their job

Aerobic respiration

glucose from food reacts with oxygen to produce energy

alkaline

has a pH greater than 7.

Alveoli

air sacs in the lungs where gaseous exchange happens

Amplitude

determines how loud or soft a sound is

amylase enzyme

enzyme responsible for the breakdown of starch.

Anaerobic respiration

chemical reactions that release energy without oxygen

Angle of incidence

angle between the normal and an incident ray

Angle of reflection

angle between the normal and a reflected ray

Angle of refraction

angle between the normal and a refracted ray

antibodies

chemicals produced by certain white blood cells, help to destroy microbes

anus

the end point of the digestive system.

Apparent depth

distance an object appears to be below the surface of a transparent material (due to refraction)

Arteries

blood vessels that carry blood away from the heart

Atoms

the smallest bit of something

Attract

force pulling towards something

Auditory nerve

nerve that carries electrical signals from the ear to the brain so we can hear
