Build a Better Body

• Blood that has passed through the vena cava and then passes through the right atrium.
• Once the right atrium contracts blood is forced through the tricuspid valve also called the atrioventricular. Fancy name for something that sits between the atrium and ventricles of the heart. Located on the upper right side of the heart
• Then the blood, once the tricuspid valve opens, flows to the right ventricle
• Blood is pumped up through the pulmonary valve when the right ventricle contracts
• Through the pulmonary valve to the pulmonary artery. This sits in the hole where the aorta wraps around.
• From there the pulmonary artery branches to the left and to the right eventually connecting to the lungs
• From the lungs the now oxygenated blood enters the pulmonary veins
• Then onto the left atrium, located on the upper left side of the heart
• Through the Mitral Valve, also called bicuspid because there are” two little flaps” Bi meaning 2
• Down the the left ventricle the blood is pushed upward defying gravity!Through the aortic valve (that doesn’t get enough credit when compared to its neighbor THE AORTA- which carries blood all over the body

What is your heartbeat? 

• Your heartbeat is an electrical current traveling through the muscles of your heart. This electrical current keeps your heart pumping blood in a rhythm.

What is the flow of the electrical current of your heart?

1. Sinoatrial node (SA)
2. Atrioventricular node (AV)
3. Atrioventricular bundle
4. Left and Right bundle branch

What is blood pressure?

• Blood pressure is the pressure you blood puts on the walls of your heart.

How is your blood pressure measured?

• To measure your blood pressure they use two instruments, the sphygmomanometer and a stethoscope.

1. A physician will find your brachial artery, which is the main artery in your arm. They will wrap a cloth cuff, that has a rubber bag inside of it, around you upper arm. This cuff is part of the sphygmomanometer.
2. The physician will put the head of the stethoscope over the crook of your elbow, right on your brachial artery to hear your heart rate.
3. When they can hear your heart rate, they will inflate the rubber bag that is inside the cloth cuff, by using a hand pump. They will pump the cuff up to 150/ 160 hg, by looking at a gage attached to the cuff and pump.
4. Next they will slowly release air from the rubber bag.
5. Listening through the ear pieces of the stethoscope, the physician will listen for little clicks. They are listening for two specific clicks, the first and last. The first click is the systolic rate. The last click is the diastolic rate. When they hear these clicks they will write down the number of hg the cuff is at by looking at the dial.
6. The average adult heart rate should be around 120 (systolic rate) / 80 (diastolic rate) hg.

What is your diastolic and systolic rate?

• Your diastolic rate is the pressure your blood is putting on your heart when it is resting.
• Your systolic rate is the pressure your blood is putting on your heart when it is contracting or squeezing blood through.

Dysfunctions and Treatments 

• Myocardial Infarction: 
  • Definition: Heart attack
  • Treatment: medications, surgery and/ or rehabilitation
• Bradycardia:
  • Definition: Slow heart rate
  • Treatment: Medications or pacemaker
• Tachycardia:
  • Definition: Fast heart rate
  • Treatment: Medications or pacemaker
• Hypertension:
  • Definition: High blood pressure
  • Treatment: Lifestyle changes or medications
• Congenative Heart Failure:
  • Definition: When the heart cannot pump the amount of blood it needs
  • Treatment: LVAD inserted into the left ventricle, beta blockers, or lifestyle changes
• Mitral Valve Prolapse:
  • Definition: Improper closure of the mitral valve
  • Treatment: Blood thinners or valve thinners/ replacement
• Aneurysm:
  • Definition: Widening of the atrial walls ( Bulge or build up in a blood vessel) 
  • Treatment: Surgery or medications

Do you love someone?

Do you want them to be around a long time to fully flourish with a beating heart?

Get off the coach and exercise, your heart is the organ controlling every other function of the body. Without it working properly…. You are a goner…

610,000 people die of heart disease in the United States every year. That’s 1 in every 4 deaths!!!

To assess a patient's endocrine system, each endocrine organ should be assessed for any anatomical and structural defects, and examine the levels of hormone being secreted by each organ as higher or lower production than average can lead to a disorder.

Assessments

-Spirometry: A test to assess how well your lungs are functioning based on how much air you inhale, and exhale.

-Pulse oximetry: A test to estimate oxygen levels in your blood.

-Lung-Diffusion Capacity: A test used to determine how well carbon dioxide and oxygen are transferred between the lungs.

Dysfunctions and Their Treatments

Asthma- Chronic inflammation of the airways of the lungs. Treatment: Avoiding smoking, oral medications, inhalers.

Lung cancer- Form of cancer that originates in the lungs. Treatment: partial lobectomy, radiation, quitting smoking.

COPD/Chronic Obstructive Pulmonary Disease- A term that covers many diseases, such as emphysema, bronchitis (chronic), and non-reversal asthma. Treatment: inhaled steroids.

Asthma    COPD

Ways To Maintain Your Respiratory Health:

-Do not EVER smoke or use electronic cigarettes

-Understand that coughs lasting more than 2 weeks should be looked into by a physician

-Do what is necessary to treat any dysfunction you may be experiencing (such as using your inhaler if you have asthma)

-Alveoli don't regenerate, so just know the choices you make when your young cannot be reversed completely.
