1. Heart Disease
3. (Respiratory Diseases)
Notes will be taken over the bulleted
Oxygen, returns to the heart by way of veins and enters the right atrium through the Superior or Inferior
With one contraction,
The blood that has filled the ventricle is pushed down into the right ventricle.
Contraction, the blood in the right ventricle is pushed through the pulmonary artery to the lungs.
2 upper Atria
2 Lower Ventricles
Anatomy of the heart
Blood, high in oxygen, returns to the heart from the lungs and enters the left atrium. From there, it’s pumped to the left ventricle. When the ventricle contracts, it forces the fresh supply of blood into the aorta to be circulated through the body.
In the lungs, carbon dioxide will be
dropped off and fresh oxygen will be
Arteries that supply the heart muscle
(myocardium) with oxygen-rich blood.
Angina (left shoulder/chest pain)
- A warning sign of coronary artery
Heart Attack (Myocardial infarction)
- Blood supply has stopped in one or more
of the coronary arteries. Heart muscle
Besides CAD, another form of
heart disease is:
Sudden Cardiac Death
Also called Hypertrophic Cardiomyopathy,
- What happens? This genetic condition causes the heart muscle thicken and loses its ability to sustain a regular rhythm.
- Athletes should have their heart screened during their yearly physical exam.
- It’s normal for athletes who are out of shape to have symptoms of a racing heart, shortness of break, or unusual fatigue during workouts. But, athletes who find these symptoms to be regular or unusual should be evaluated by a___________________________.
According to the CDC, About 70 young athletes in the United States die each year from Sudden Cardiac Death.

Which of the 3 risk factors for lifestyle-related diseases are most associated with causing heart disease?
“Uncontrolled growth of abnormal cells that have the ability to migrate from the original site and spread to distant sites.”
There are over 100 different types of cancer.
Malignant: A tumor that is cancerous. It will metastasize.
Benign: A tumor that remains in one place and does not consist of malignant cells.
Cancer of white blood cells
Plasma: the liquid part
Red Blood Cells: they carry oxygen
*White Blood Cells: they fight infection
Platelets: cause blood to clot
*White blood cells
(55% of whole blood)
White blood cells and platelets

Red blood cells

Organs. It is one of the most common cancers found in children.
Any cancer that occurs on the lips, gums, tongue, roof, or inner cheek of the mouth.
Tobacco is the prime risk factor:
1. Avoid the known risk factors such as excessive exposure to the sun and carcinogens.
2. The key to surviving cancer is early
diagnosis and treatment.
3. Once cancer has a chance to metastasize, it’s much more difficult to treat.
Brain damage caused by a loss of blood circulation. The blockage usually occurs when a clot or (less often) piece of plaque breaks away from an artery elsewhere in the
body and lodges within a blood vessel of the brain.
A stroke is often called a “brain attack” and the risk factors are the same as for heart attack.Heredity + Lifestyle Choices(family history)(tobacco, poor diet, lack of exercise)*Women are at an increased for cardiovascular disease, such as heart attack or stroke, if they are a smoker and use hormone-based birth control such as birth control pills, vaginal ring, patch, or injections.
Characterized by high levels of blood glucose resulting from defects in insulin production, insulin action, or both.
Most of the food we eat will end
up as glucose in our bloodstream.
Another term for glucose is “blood sugar”.
Glucose is the body’s main energy supply
to fuel bodily processes.
Too much glucose in the bloodstream at once can be fatal. This is where insulin comes into play....
Insulin is a hormone produced by the pancreas responsible for transporting glucose out of the bloodstream to be delivered to the body’s cells.
Besides secreting pancreatic juice and digestive enzymes, the
pancreas produces several important hormones, including insulin,
glucagon, and somatostatin).
An autoimmune disease
The person’s immune system destroys
the cells of the pancreas (beta cells)
responsible for creating insulin.
the person must put
Insulin into his body
since the beta cells
are unable to produce
and release insulin.
Most Common Type of Diabetes
In type 2 diabetes, either the body does not produce enough insulin or the cells ignore the insulin.
Obesity is the prime risk factor for Type 2 Diabetes
Can often be treated through
diet and exercise.
