Blood and Blood Vessels
Aim of Lesson: to study the structure of Starter
blood and blood vessels.
What do you already know about blood v
You should be able to identify the components of
blood and body circulations.
You should be able to describe the structure of
blood vessels.
You should be able to explain the blood groups What is present in blood?
and transfusion matching.
Key Terms for the Lesson Capillaries
Veins
Arteries
,Circulation
The human cardiovascular system is a
double circulatory system. This means
____________
that for every complete circulation of the
body, the blood passes through the heart
twice
_______________.
What is the benefit of this?
,Blood Vessel Features
Artery Thick wall containing lots of smooth __________
_________ muscle and _________ elasti
fibres to withstand high pressure of blood form the left ventricle of the
recoil after pulsation of blood as pressures chan
Elastin allows ____________
(higher systolic pressure just after heart has contracted, lower diastolic
between contractions).
lumen
Small ___________.
Vein Thin walls as blood has low pressure.
