Chemostasis - maintenance of pH and electrolyte balance
Haemostasis - maintenance of circulatory system
Thermostasis - maintenance of internal temperature

What does the cardiovascular system compose of? (5 things)
veins
capillaries
arteries
heart
blood
3 of 10
how does the heart function?
The heart uses electrical
signals to make the
heart’s walls contract.
When the heart
contracts, blood is
pumped to all parts of
the body.
4 of 10
What is the bundle of his and what is it's function?
The bundle of his is a bundle of cardiac muscle fibres that conducts the
electrical impulses that regulate the heartbeat.
5 of 10
What do the Purkinje fibres do in relation to the bundle of his?
the Purkinje fibres carry the
contraction impulse from both the left and right bundle
branch to the myocardium of the ventricles.
6 of 10
what are the layers of the heart?
The epicardium (outer layer)
The myocardium (middle layer) - composed of cardiac muscle
The endocardium (inner layer)
7 of 10
What are the 4 chambers of the heart?
Right ventricle
Left ventricle
Right atrium
Left atrium
8 of 10
What are the 4 valves?
Tricuspid valve - Separates right atrium from right
ventricle
Pulmonary valve - Separates right ventricle
from pulmonary artery
Mitral valve - Separates left atrium from left
ventricle
Aortic valve - Separates left ventricle from aorta
9 of 10
what is the circulation of blood?
Superior/inferior vena cava - right atrium - tricuspid valve - right ventricle - pulmonary valve -pulmonary arteries - lung
lungs - pulmonary veins - left atrium - left ventricle - aorta - rest of body.
