The Circulatory System is the system of the Heart, Blood, and blood vessels.
The Body’s Transport System •The circulatory system consists of organs and tissues that transport essential materials to body cells and remove their waste products. •This body system is also known as the cardiovascular system.
Parts of the Circulatory System •Your circulatory system includes your heart, blood vessels, and blood. Your heart pumps blood through two major pathways. – Pulmonary circulation is the flow of blood from the heart to the lungs and back to the heart.

There are three types of blood vessels:
There are three types of blood vessels: Arteries, take blood away from the heart to the body parts.
There are three types of blood vessels: Veins, take blood back to the heart.
There are three types of blood vessels: Capillaries, connect the arteries to the veins. This is where the Oxygen and Nutrients are delivered to the body parts.
The Circulatory System Your heart is an organ divided into four chambers. Each upper chamber is called an atrium, and each lower chamber is called a ventricle. Pulmonary veins carry oxygen­rich blood from your lungs to your heart. Right atrium Left atrium
Pulmonary arteries carry carbon dioxide­ filled blood from your heart to your lungs. Right ventricle Left ventricle Blood Types •There are four different blood types—A, B, AB, and O. These blood types are determined by the presence or absence of certain substances. •Knowing a person’s blood type is essential if the person needs a blood transfusion. Mixing certain blood types can cause dangerous immune responses such as fevers, difficulty in breathing, and possibly death.
Blood Types
Giving and Receiving Blood •People who are between the ages of 17 and 70 and in good health can give blood. •The blood is frozen or refrigerated and stored in blood banks for later use by hospitals. U.S. regulations make it very safe to give and receive blood.
Blood Pressure •As blood is moved through your body, it exerts pressure against the walls of blood vessels. – As your heart contracts to push blood into your arteries, your blood pressure is at its highest point. This is called systolic pressure. – As your heart relaxes to refill, blood pressure is at its lowest point. This is called diastolic pressure.

Let’s follow that drop of blood through the blood vessels. When it leaves the left ventricle of the heart it goes into the Aorta. This vessel is the largest artery in the body. Soon after leaving the heart, this vessel branches so the droplet could move into the smaller arteries leading to The head or arms. Let’s assume this droplet travels down toward the Legs. The largest artery divides to carry blood to each leg. This droplet Of blood goes into one of the branches. From here, the blood travels
In smaller and smaller arteries until it reaches the end of the big toe. The blood vessel here is so small it can not be seen by the naked eye. This tiny vessel is a capillary.

At this point the droplet nourishes the cells next to the tiny vessel and takes away the waste products. Now that the blood has given up its food and oxygen it must return to the heart.

It moves into a larger blood vessel. The blood vessel is called a vein. This droplet joins other blood going back to the heart. The blood vessels become larger and larger. Finally, they all join one large blood vessel that receives all the blood from the lower part of the body. This blood vessel is called the Inferior Vena Cava.
Another blood vessel collects all the blood from the head and arms. This vessel is called the Superior Vena Cava.
Another blood vessel collects all the blood from the head and arms. This vessel is called the Superior Vena Cava. Both then separately enter the right atrium of the heart.
