Hello again crystal4290-ga,
Several of the websites I gave you in my answer had references to the
dimensions of the human heart (sometimes in conjunction with the
weight) along with very detailed illustrations and diagrams. I?ve
included these plus some additional references with more precise
measurements as well as explicit references to the measurement of the
aorta and aortic valve.
Since you said that you are making a 3D animation, I thought you would
find the many detailed illustrations I included helpful for your
design. Many of them are very complete and show all the structures of
the human heart. I trust that the additional measurements I?ve
included will meet your needs.

Size.
The heart, in the adult, measures about 12 cm. in length, 8 to 9 cm.
in breadth at the broadest part, and 6 cm. in thickness. Its weight,
in the male, varies from 280 to 340 grams; in the female, from 230 to
280 grams. The heart continues to increase in weight and size up to an
advanced period of life; this increase is more marked in men than in
women. 2
Right Atrium (atrium dextrum; right auricle).?The right atrium is
larger than the left, but its walls are somewhat thinner, measuring
about 2 mm.; its cavity is capable of containing about 57 c.c. It
consists of two parts: a principal cavity, or sinus venarum, situated
posteriorly, and an anterior, smaller portion, the auricula. 11
Left Atrium (atrium sinistum; left auricle).?The left atrium is rather
smaller than the right, but its walls are thicker, measuring about 3
mm.; it consists, like the right, of two parts, a principal cavity and
an auricula

Subject: Re: heart dimensions
The normal values for the diameter or thickness of each cardiac
structure are listed below in cm. These values shouldn't change much
with exercise although the LV systolic diameter may be smaller at peak
exercise since the left ventricle is beating more forcefully.
Aorta: 2.5-3.5
Left Atrium: 3.0-4.0
LV Diastolic: 3.5-4.5
LV Systolic: 2.5-3.5
IV Septum: 0.8-1.2
Post. Wall: 0.8-1.2
Ejection Fraction: >55% (not measured in cm)

The average adult heart is about the size of a clenched fist and
weighs about 11 ounces (310 grams).

The heart weighs between 7 and 15 ounces (200 to 425 grams) and is a
little larger than the size of your fist.

Each person's heart is about the size of the person's fist. A newborn
baby's heart weighs about 2/3 ounce (19 grams). An adult's heart
weighs from 9 to 11 ounces (255 to 312 grams).
-------------------------------------------------
http://www.jdaross.cwc.net/heart1.htm
Although it is not much larger than a clenched fist and weighs less
than a pound, (approximately 300 grams) the human heart is a truly
incredible organ.
The heart rests on the muscular diaphragm and is attached via its
covering to this muscular partition that separates the chest and
abdominal cavities. It measures about 120mm (4.75") in length, 90mm
(3.5") in width at its broadest part, and 60mm (2.4") in thickness.

2. The Aorta
The aorta is the main trunk of a series of vessels which convey the
oxygenated blood to the tissues of the body for their nutrition. It
commences at the upper part of the left ventricle, where it is about 3
cm. in diameter, and after ascending for a short distance, arches
backward and to the left side, over the root of the left lung; it then
descends within the thorax on the left side of the vertebral column,
passes into the abdominal cavity through the aortic hiatus in the
diaphragm, and ends, considerably diminished in size (about 1.75 cm.
in diameter), opposite the lower border of the fourth lumbar vertebra,
by dividing into the right and left common iliac arteries. Hence it is
described in several portions, viz., the ascending aorta, the arch of
the aorta, and the descending aorta, which last is again divided into
the thoracic and abdominal aortę.
-------------------------------------------------
http://www.bartleby.com/107/141.html
The pulmonary artery conveys the venous blood from the right ventricle
of the heart to the lungs. It is a short, wide vessel, about 5 cm. in
length and 3 cm. in diameter, arising from the conus arteriosus of the
right ventricle. It extends obliquely upward and backward, passing at
first in front and then to the left of the ascending aorta, as far as
the under surface of the aortic arch, where it divides, about the
level of the fibrocartilage between the fifth and sixth thoracic
vertebrę, into right and left branches of nearly equal size.

aorta
primary artery of the circulatory system in mammals, delivering
oxygenated blood to all other arteries except those of the lungs. The
human aorta, c.1 in. (2.54 cm) in diameter, originates at the left
ventricle of the heart.

Anatomy of the Human Heart
Coronary Arteries
The initial segment of the left coronary artery is called the left
main coronary. This blood vessel is approximately the width of a soda
straw and is less than an inch long. It branches into two slightly
smaller arteries: the left anterior descending coronary artery (2) and
the left circumflex coronary artery (3).
Just like branches on a tree, the coronary arteries branch into
progressively smaller vessels.
The aorta is the largest single blood vessel in the body. It is
approximately the diameter of your thumb.

http://www.pbs.org/wgbh/nova/eheart/facts.html
The aorta, the largest artery in the body, is almost the diameter of a
garden hose. Capillaries, on the other hand, are so small that it
takes ten of them to equal the thickness of a human hair.

The aorta is an inch in diameter and has thick walls to withstand the
force of the blood that courses through it.

Various features of the aortic valve were measured: circumference,
length between the commissural end point and central point of
coaptation, surface diameter, and surface area.
