an abnormal rhythm of the heart.
arrhythmia
1 of 27
an abnormal rhythm of the heart when the atria beat very fast and incompletely.
atrial fibrillation
2 of 27
stimulates the ventricles to contract after imposing a slight delay to ensure atrial contraction is complete.
atrioventricular node
3 of 27
a slow heart rhythm of below 60 beats per minute.
bradycardia
4 of 27
conducting tissue composed of purkyne fibres that passes through the septum of the heart
bundle of his
5 of 27
the events of a single heartbeat, composed of diastole and systole.
cardiac cycle
6 of 27
the transport system of an animal.
circulatory system
7 of 27
a circulatory system where the blood is enclosed in blood vessels and does not come into direct contact with the cells of the body beyond the blood vessels.
closed circulatory system
8 of 27
the stage of the cardiac cycle in which the heart relaxes and the atria and then the ventricles fill with blood.
diastole
9 of 27
a circulatory system where the blood travels twice through the heart for each complete circulation of the body. In the first circulation blood is pumped by the heart to the lungs. In the second circulation oxygenated blood is pumped by the heart to t
double circulatory system
10 of 27
extra heartbeats that are out of the normal rhythm.
ectopic heartbeat
11 of 27
a technique for measuring tiny changes in the electrical conductivity of the skin that result from the electrical activity of the heart. This produces a trace which can be used to analyse the health of the heart.
electrocardiogram
12 of 27
the transport medium or ‘blood’ in insects
haemolymph
13 of 27
modified tissue fluid that is collected in the lymph system.
lymph
14 of 27
white blood cells that make up the specific immune system.
lymphocytes
15 of 27
a transport system where substances are transported in a mass of fluid.
mass transport system
16 of 27
muscle which has its own intrinsic rhythm.
myogenic
17 of 27
the tendency of water to move into the blood by osmosis as a result of the plasma proteins.
oncotic pressure
18 of 27
a circulatory system with a heart but few vessels to contain the transport medium.
open circulatory system
19 of 27
blood that has passed through the gas exchange organs (e.g. lungs) and is high in oxygen.
oxygenated blood
20 of 27
the main component of blood, a yellow fluid containing many dissolved substances and carrying the blood cells.
plasma
21 of 27
tissue that conducts the wave of excitation to the apex of the heart.
purkyne fibres
22 of 27
a circulatory system where the blood flows through the heart and is pumped out to travel all around the body before returning to the heart.
single circulatory system
23 of 27
region of the heart that initiates a wave of excitation that triggers the contraction of the heart.
sinoatrial node
24 of 27
the stage of the cardiac cycle in which the atria contract, followed by the ventricles, forcing blood out of the right side of the heart to the lungs and the left side of the heart to the body.
systole
25 of 27
a fast heart rhythm of over 100 beats per minute at rest.
tachycardia
26 of 27
the solution surrounding the cells of multicellular animals.
tissue fluid
27 of 27
