Study Guide for the Circulatory and Respiratory System Test
Be Able to Label Heart Diagrams-Use Diagrams in your journal to study by!!!
Be able to trace the blood’s travels through the heart (see heart diagram)
The job of the circulatory system is to transport oxygen, wastes, and other materials
throughout the body.
The heart is a muscle in your chest that pumps blood.
Red blood cells carry oxygen to the cells and remove carbon dioxide.
Plasma is the liquid part of the blood.
The smallest blood vessel in the body is a capillary.
The upper chambers of the heart are called the atriums.
Platelets are the part of the blood that causes clotting to stop bleeding.
The aorta is the largest artery in the body.
Valves separate the heart chambers and keep the blood flowing in one direction.
The septum is the wall between the right and left ventricles.
The exchange between blood and body cells happens in the capillaries.
The universal donor that can donate to all other blood types is O.
Blood type A can safely donate to types AB and A.
Antigens are the protein markers on a red blood cell that determines blood type.
White blood cells are the part of the blood in charge of producing antibodies for defense.
Red Blood Cells—contain hemoglobin, transport oxygen, don’t have a nucleus, and are
produced in the bone marrow.
White blood cells—fight bacteria, viruses and other invaders, and make up pus
Plasma—consists mostly of water (90%), is colorless, and can leave capillaries
Platelets—help the blood to clot
Arteries---usually carry blood with a lot of oxygen, do not have valves, lie deeper in the
body for protection, and carry blood AWAY from the heart.
Veins---usually carry dark reddish blood, have valves, lie closer to the skin, and carry
blood TO the heart.
Capillaries--- thin microscopic vessels that exchange materials between the blood and the
cells
