Understanding Health and Medical Conditions

• The human body is made up of smaller systems that work together.
• Healthy cells make up healthy organs, and healthy organs work together in systems to keep the body breathing, moving, thinking, and releasing energy.
• Tiny molecules can make a person feel better or worse.
• A person has a medical condition when their cells aren’t getting the molecules they need.
• Doctors often look for medical conditions when a patient’s symptoms aren’t caused by bacteria or virus.
• Anemia means having fewer red blood cells and the amount of oxygen in blood is also lower than normal.
• Normally in a healthy person:
• Oxygen from lungs enters the bloodstream.
• Red blood cells pick up the oxygen.
• Oxygen is then released to body cells.
• Reason of anemia:
• Not getting enough iron needed to make enough red blood cells → less red blood cell count → less oxygen carried to the body cells.
• Anemia Patient’s symptoms:
• Feeling tired all the time - Feeling like going to faint sometimes - Not breathing well.
• Anemia Treatment:
• Eating plenty of foods with lots of iron like beans, meat, and greens like spinach.
• Taking iron pills.
• Asthma means the tubes inside lungs swell up during exercise or irritation and get narrow. This allows less air to enter, making it harder to breathe.
• Normally in a healthy person:
• When you breathe in, you pull oxygen molecules from the air into your respiratory system.
• In your respiratory system, the oxygen moves through tiny structures called alveoli.
• In the alveoli, oxygen molecules move from the respiratory system into the blood.
• Your blood carries oxygen delivering it to all the cells of your body.
• Reason of asthma:
• The tiny tubes in lungs are squeezing shut during exercise or dust.
• So less oxygen in the respiratory system → less oxygen moving into the blood → not enough oxygen getting to body cells → cells can’t do any of their functions.
• Asthma Patient’s symptoms:
• Having trouble breathing, especially when during exercise or running - chest is tightening up - Wheezing (to make noise while trying to breathe).
• Asthma Treatment:
• Inhalers to help patients breathe during asthma attacks.
• The inhaler stops the tubes in lungs from swelling, keeping the tubes wide and letting in more oxygen.
• Knowing what causes asthma attacks and how to avoid them.
• Pancreas is part of the digestive system and helps with the digestion of food.
• Pancreas injury can mean that the body doesn't have enough enzymes to break down food and can lead to problems such as being tired all the time and diarrhea.
• Patients with pancreatitis often need to take medicines with enzymes to help them digest food better.
