Capillaries

Veins&nbsp;carry deoxygenated blood from the body to the heart, where it can be sent to the lungs.

The capillaries have very thin walls, and through them,&nbsp;nutrients and oxygen&nbsp;are delivered to the cells. Waste products are brought into the capillaries

The heart is there to pump enough blood to deliver a continuous supply of oxygen and other nutrients to the brain and the other vital organs

Arteries transport blood away from the heart and branch into smaller vessels

The heart pumps about 100 gallons of blood through the body each hour&nbsp;– enough to fill 1,600 drinking glasses Your heart doesn’t stop when you sneeze, but a sneeze can briefly change its rhythm

High Blood Pressure- If you have high blood pressure, also called hypertension, it means the force is higher than it should be. High blood pressure can damage your heart and lead to heart disease, stroke, or kidney disease. Heart Attack- A&nbsp;heart attack&nbsp;occurs when not enough blood reaches your heart. This can happen due to artery blockage. Heart attacks damage the heart muscle and are medical emergencies.
