#1
Front (Question)

4 components of the blood

Back (Answer)

plasma, red blood cells, white blood cells, platelets

#2
Front (Question)

function of red blood cells

Back (Answer)

Transport oxygen around the body

#3
Front (Question)

function of platelets

Back (Answer)

blood clotting at a wound

#4
Front (Question)

Function of plasma

Back (Answer)

It carries many substances dissolved in it including glucose for body cells

#5
Front (Question)

Function of white blood cells

Back (Answer)

defend the body against infectious organisms

#6
Front (Question)

adaptation of red blood cells

Back (Answer)

Shape increases the surface area to allow more oxygen to be absorbed efficiently. No nucleus, so the whole cell is full of haemoglobin.

#7
Front (Question)

What allows red blood cells to carry oxygen?

Back (Answer)

haemoglobin

#8
Front (Question)

What does plasma contain?

Back (Answer)

Hormones, antibodies, nutrients, waste substances

#9
Front (Question)

Name of process of white blood cells engulfing bacteria

Back (Answer)

Phagocytosis

#10
Front (Question)

product of oxygen and haemoglobin

Back (Answer)

oxyhaemoglobin

#11
Front (Question)

Name the 3 blood vessels

Back (Answer)

arteries, veins, capillaries

#12
Front (Question)

Function of arteries

Back (Answer)

carry blood away from the heart

#13
Front (Question)

Adaptations of arteries

Back (Answer)

small lumen - pressure and flow is high thick walls - withstand high pressure elastic tissue - allows blood vessels to stretch and recoil to smooth blood flow

#14
Front (Question)

What type of blood does arteries carry

Back (Answer)

oxygenated blood

#15
Front (Question)

function of veins

Back (Answer)

carry blood back to the heart

#16
Front (Question)

Adaptation of veins

Back (Answer)

Wide lumen - keeps blood flowing smoothly, at a low pressure Valves prevent back flow of blood Thin outer wall - muscles can squeeze vein: keeps blood moving up the body

#17
Front (Question)

What type of blood do veins carry?

Back (Answer)

deoxygenated blood

#18
Front (Question)

What do veins contain?

Back (Answer)

valves

#19
Front (Question)

function of valves

Back (Answer)

prevent back flow of blood

#20
Front (Question)

function of capillaries

Back (Answer)

to exchange of materials such as oxygen & carbon dioxide between the blood and body cells.

#21
Front (Question)

Adaptation of alveoli

Back (Answer)

• millions of tiny capillaries (large surface area) • thin wall/one cell thick (short diffusion distance) • narrow lumen (increases diffusion time, decreases diffusion distance) • circulation maintains concentration gradient (low oxygen, high carbon dioxide)

#22
Front (Question)

What do capillaries link?

Back (Answer)

arteries and veins

#23
Front (Question)

What does double circulatory system mean?

Back (Answer)

The heart pumps blood around the body in two circuits.

#24
Front (Question)

4 chambers of the heart

Back (Answer)

Right atrium, right ventricle, left atrium, left ventricle
