Carotid Artery
The carotid arteries are major blood vessels in the neck
that supply blood to the brain, neck, and face.
Subclavian Artery
Either of a pair of arteries, one on each side of the body, that carry the main supply of blood to the arms.
Subclavian Artery
Either of a pair of arteries, one on each
side of the body, that carry the main
supply of blood to the arms.
Lungs
Each of the pair of organs situated within the rib cage, consisting of
elastic sacs with branching passages into which air is drawn, so that
oxygen can pass into the blood and carbon dioxide be removed. Lungs
are characteristic of vertebrates other than fish, though similar
structures are present in some other animal groups.
Heart
The heart is a hollow, pump-like organ of blood
circulation consisting of many muscles. It is
located in the chest, between the lungs, slightly to
the left.
Vena Cava
a large vein carrying deoxygenated blood into the heart. There are
two in humans, the inferior vena cava (carrying blood from the
lower body) and the superior vena cava (carrying blood from the
head, arms, and upper body).
Aortic Artery
The aorta is the largest and the main artery in the body. It extends
all the way down to the abdomen and splits into two where it
distributes oxygenated blood to all parts of the body.
Femoral Artery and Vein
The femoral artery is the main artery that provides oxygenated
blood to the tissues of the leg. It passes through the deep tissues of
the femoral (or thigh) region of the leg. There, it splits into the two iliac arteries
in the legs.
• The cardiovascular system consists of veins and arteries
• The arteries send oxygen-rich blood from the heart and veins
send oxygen depleted blood to the heart
• transports nutrients and wastes to and from all body tissues
Heart Attack
When the heart doesn’t get enough oxygen and blood nourish, a heart
attack occurs. This is because fatty matter, calcium, proteins, and
inflammatory cells build up within the arteries to form plaques of
different sizes which can clog the arteries. The plaque deposits are hard
on the outside and soft and mushy on the inside.
Symptoms include
•Irregular or rapid heart beat
•Nausea and stomach problems
•Fatigue
•Insomnia
•Joint pain
•Arm pain
•Pressure on the chest
•Shortness of breath
•Sweating
•Spasms in the chest
Blood Clot
When plaque builds up within the arteries, a blood clot is formed. This causes all
the blood within the arteries to stop flowing and the process of blood flow can
stop.
Symptoms include
•swelling
•pain
•tenderness
•a warm sensation
•pain in your calf when you
stretch your toes upward
•a pale or bluish discoloration
Congenital Heart Disease
Doctors don’t always know why babies have a congenital heart defect. They tend
to run in families. Some things that can cause this disease are problems with
genes or chromosomes in the child, such as down syndrome, or taking
certain medications or alcohol or drug abuse during pregnancy.
Symptoms include
•shortness of breath
•problems of exercise
•A bluish tint to the skin
•Fast breathing and poor feeding
•Poor weight gain
•Getting a lot of lung infection
•Not being able to exercise
Heart Valve Disease
Certain conditions can change the form and position of the heart valve. Extremely
high blood pressure can enlarge the heart or the main arteries.
Atherosclerosis is a condition in which a waxy substance called plaque builds up
inside the arteries.
Symptoms include
•Chest pain
•Shortness of breath
•fatigue
•weakness
•Lightheadedness or loss of consciousness
•Swollen ankles, feet or abdomen
Heart Failure
Alcohol or drug abuse can cause heart failure over time. High blood pressure
is another factor of heart failure occurring, the blood pushes up against the
walls of the arteries. If the pressure continues to rise or stay at the same
level there is plaque build up and that will lead to heart failure.
Symptoms include
•congested lungs
• dizziness
• fatigue
• weakness
• rapid and irregular heartbeats.
