PHYSICAL WELLNESS
your body’s pumping engine
THE HEART
The heart is like the main engine of your circulatory system. It continuously pumps blood, delivering oxygen and nutrients to every part of your body while removing waste products.
Pumps oxygen-rich blood to the body and oxygen-poor blood to the lungs
Maintains blood pressure and circulation
Supports nutrient delivery and waste removal
Coordinates with the nervous and endocrine systems to adjust heart rate and strength
Helps maintain body temperature through blood flow
THE HEART BASICS
Common Terms + Simple Definitions
Here’s a mini glossary for heart related words you’ll see throughout the site:
Atrium - Upper chamber of the heart that receives blood
Ventricle - Lower chamber that pumps blood out of the heart
Valves - Flaps that keep blood moving in the right direction
Cardiac Muscle - Specialized heart muscle that contracts rhythmically
Pacemaker (SA Node) - Heart’s natural “timer” controlling heartbeat
Coronary Arteries - Blood vessels that supply the heart muscle itself
WHAT THE HEART WORKS WITH
THE HEART + OTHER SYSTEMS
Arteries & Veins → Carry blood away from and back to the heart
Capillaries → Tiny vessels where gas and nutrient exchange occurs
Lungs → Oxygenate blood and remove carbon dioxide
Blood Cells → Red blood cells carry oxygen, white blood cells fight infection, platelets assist clotting
Nervous System → Regulates heart rate and rhythm
Endocrine System → Hormones like adrenaline influence heart function
A HealthY HEART…
