21
Q

Antihypertensives

A

A class of drug that is used as a treatment for high blood pressure (hypertension).

22
Atherosclerosis
A disease caused by a buildup of fatty deposits within arteries which narrows them and can restrict blood flow.
23
Cardiovascular disease (CVD)
A term used to describe a group of diseases related to the heart and blood vessels
24
Coagulation
The process of blood turning into a gel and forming a clot, often in response to a broken blood vessel to prevent blood loss
25
Risk factor
A factor that increases the likelihood of a person developing a disease
26
Statins
A class of drug that is used to lower cholesterol levels in the blood.
27
Dipole
A molecule which has an unequal distribution of electrons which causes atoms in the molecule to have partial charges
28
Mass transport
The bulk transport of substances to all parts of an organism using mass flow.
29
Solvent
A substance which solutes can dissolve in to form a solution.
30
Aorta
The main artery that carries oxygenated blood away from the heart at high pressure.
31
Arteriole
A smaller type of blood vessel that connects arteries with capillaries
32
Artery
A type of blood vessel that carries blood at high pressure away from the heart.
33
Atrial systole
The phase in the cardiac cycle following diastole where the atria contract and force the blood into the ventricles.
34
Atrium
A type of chamber in the heart which receives blood directly from a vein and passes it on to a ventricle.
35
Capillary
A very small blood vessel with thin walls and a small diameter used for substance exchange in tissues.
36
Cardiac diastole
The phase in the cardiac cycle following ventricular systole where the atria and ventricles are both relaxed and blood flows into the atria.
37
Coronary artery
The main artery that supplies the heart tissue with blood.
38
Left atrium
The chamber in the heart that receives oxygenated blood from the pulmonary vein and passes it on to the left ventricle.
39
Left ventricle
The chamber in the heart that receives oxygenated blood from the left atrium and pumps it out of the heart to the rest of the body.
40
Pulmonary artery
The main artery that carries deoxygenated blood from the heart to the lungs for reoxygenation
41
Pulmonary vein
The main vein that carries oxygenated blood away from the lungs and back to the heart.
42
Right atrium
The chamber in the heart that receives deoxygenated blood directly from the vena cava and passes it on to the right ventricle
42
Right ventricle
The chamber in the heart that receives deoxygenated blood from the right atrium and pumps it out of the heart to the lungs for reoxygenation.
43
Vein
A type of blood vessel that carries blood at lower pressure into the heart from other parts of the body.
44
Vena cava
The main vein that carries deoxygenated blood into the right atrium of the heart.
45
Ventricle
A type of chamber in the heart which receives blood from the atrium above it and pumps it out of the heart.
46
Ventricular systole
The phase in the cardiac cycle following atrial systole where the ventricles contract and force the blood out of the heart and around the body.
47
Venule
A smaller type of blood vessel that connects capillaries with veins.
