 circulatory system The group of organs and tissues that act as transfer stations carrying needed materials to cells and removing their waste products Blood vessels that carry blood away from the heart to various parts of the body Blood vessels that carry blood from all parts of the body back to the heart  arteries  veins

 pulmonary circulation When blood travels from the heart, through the lungs, and back to the heart When oxygen-rich blood travels to all body tissues except the lungs The force of blood pushing against the walls of the blood vessels  systemic circulation  blood pressure

In this lesson, you will be able to  identify the functions of the circulatory system.  describe how blood circulates through the body.  recognize how to care for your circulatory system.

Your Heart and Blood Vessels The circulatory system includes the heart, the blood vessels and the blood itself. circulatory system The group of organs and tissues that act as transfer stations carrying needed materials to cells and removing their waste products

Your Heart and Blood Vessels The heart pumps blood around the body through a network of arteries, veins, and capillaries. arteries Blood vessels that carry blood away from the heart to various parts of the body veins Blood vessels that carry blood from all parts of the body back to the heart capillaries Tiny blood vessels that carry blood to and from almost all body cells and connect arteries and veins

The Process of Circulation The process of circulation involves pulmonary circulation and systemic circulation. pulmonary circulation When blood travels from the heart, through the lungs, and back to the heart systemic circulation When oxygen-rich blood travels to all body tissues except the lungs

Blood Pressure A certain amount of blood pressure is needed to make blood circulate. blood pressure The force of blood pushing against the walls of the blood vessels

Blood Pressure A blood pressure reading measures two numbers. The first is systolic pressure and the second is diastolic pressure.

What Makes Up Your Blood? Blood is made up of plasma, red blood cells, white blood cells, and platelets. plasma The yellowish, watery part of blood Plasma makes up over half the volume of blood.

Blood Types Red blood cells are one of four types: A, B, AB, or O. Most people’s blood contains a substance called an Rh factor, a type of protein.

Blood Types and Compatibility Type O Type A Type B Type AB
