1. Macromolecule - ANSWER ✓ A type of giant molecule formed by joining
smaller molecules which includes proteins, polysaccharides, lipids, and
nucleic acids.
2. Molecule - ANSWER ✓ Two or more atoms held together by covalent
bonds.
3. Monomer - ANSWER ✓ The subunit that serves as the building block of a
polymer.
4. Monosaccharide - ANSWER ✓ A single sugar molecule such as glucose or
fructose, the simplest type of sugar.
5. Angiogram - ANSWER ✓ The radiographic visualization of blood vessels
after the injection of radiopaque substance.
6. Angioplasty - ANSWER ✓ Surgical repair or recanalization of a blood
vessel.
7. Coronary Bypass - ANSWER ✓ A surgical bypass operation performed to
shunt blood around an obstruction in a coronary artery that involves grafting
one end of a segment of vein removed from another part of the body into the
aorta and the other end into the coronary artery beyond the obstructed area to
allow for increased blood flow.
8. Heart Attack - ANSWER ✓ An acute episode of heart disease marked by
death or damage of heart muscle due to insufficient blood supply to the heart
, muscle usually as a result of coronary thrombosis or a coronary occlusion
and that is characterized especially by chest pain.
9. Cardiovascular System - ANSWER ✓ The transport system of the body
responsible for carrying oxygen and nutrients to the body and carrying away
carbon dioxide and other wastes; composed of the heart, blood vessels, and
blood.
10.Cell - ANSWER ✓ The smallest structural unit of living matter capable of
functioning independently.
11.Inferior Vena Cava - ANSWER ✓ A vein that is the largest vein in the
human body and returns blood to the right atrium of the heart from bodily
parts below the diaphragm.
12.Mitral Valve - ANSWER ✓ A valve in the heart that guards the opening
between the left atrium and the left ventricle; prevents the blood in the
ventricle from returning to the atrium. Alternative name is bicuspid valve.
13.Pulmonary Circulation - ANSWER ✓ The passage of venous blood from the
right atrium of the heart through the right ventricle and pulmonary arteries to
the lungs where it is oxygenated and its return via the pulmonary veins to
enter the left atrium and participate in systemic circulation.
14.Superior Vena Cava - ANSWER ✓ A vein that is the second largest vein in
the human body and returns blood to the right atrium of the heart from the
upper half of the body.
15.Systemic Circulation - ANSWER ✓ The branch of the circulatory system
that supplies all body organs and then returns oxygen-poor blood to the right
atrium via the veins.
16.Tissue - ANSWER ✓ An integrated group of cells with a common function,
structure, or both.
17.Tricuspid Valve - ANSWER ✓ A valve that is situated at the opening of the
right atrium of the heart into the right ventricle and that resembles the mitral
valve in structure but consists of three triangular membranous flaps.
