Circulatory System

Gabriella Camargo

The function of the circultatory system

• The function of this system is to transport nutrients, waste and carbon dioxide throughout the body.

• This system is divided into three different parts; the heart, the blood, and the blood vessels. Lots of things are happening at the same time and that is exactly what you are going learn about.

The heart

• Our heart is one of the many muscles in our bodies, it is about the size of your feet and located in the left of the top of your chest. This muscle is different, it’s special because it transmits blood throught all your body. It also carries away waste and provides the rest of our bodies with oxygen and other nutrients we need

The heart

• . Our hearts are devided into two parts, the left side is where the heart recieves some blood from our lungs and transmits it to the rest of our bodies. The right part recieves the blood from our bodies and later transmits it to the lungs which is the opposite as the left side of the heart. It is a very special organ that plays a really important role in our bodies.

The Blood

• The blood is a dark red liquid that goes all around our bodies providing us oxygen, nutrition and waste removal. Blood is a lot thicker than water because it has some cells and proteins in it. Most of us if we haven’t lost a lot of blood have about 1 gallon of blood in our bodies that is equal to 5 liters

Blood

• . Our blood has blood cells that are; red blood cells that take oxygen to the tissues, white blood cells fight infections and platelets are smaller cells that help the blood clot. Half of our blood is made up of plasma. It contains gluceous and other nutrients that make the blood do it’s function. The blood is put throughout the body by blood vessels.

Blood Vessels

• Blood vessels are a system of tubess that help transport blood all around the body. There are four typess of blood vessels including veins, capillaries, arteries and sinusoids. Veins are the blood vessels that transport blood to the heart, they are elastic

Bloos vessesles

• . Capillaries are really small blood vessels that are in the tissues of our bodies, they transport the blood from the arteries to the veins. Arteries are also elastic blood vessels that transport blood away from the heart. Sinusoids are really really small blood vessels in the liver, spleen and bown marrow.
