A ________________ separates each _____________ from the ____________________ below it so that the blood flows in only one direction. Your heart is a “2-pump” system. Valve cells neededproduced heart arteries veinscapillaries muscular organ 4 atriaventricles valveatrium ventricle blood

3. The Right Side: The ____________ ___________-filled blood from the body cells is brought into the __________ __________ through the _________ ___________ (the largest veins in the body).

The Left Side: The ________________-rich blood then goes through the ________________ _____________ to the ___________ _____________. From there, the blood goes down through a _____________ into the ___________ __________________, the largest and strongest chamber in the heart. From there, it goes up and out through the ______________, the largest artery in the body. This vessel then goes around behind the heart and digestive organs down through the middle of the _______________. carbon dioxide right atrium vena cavas valveright ventricle pulmonary arteries carbon dioxideoxygen pulmonary veinsleft atrium valve left ventricle aorta trunk

4. B. The chambers: 1. The ____________ (singular is ___________) receive blood from the body or lungs. They are ______________ and _____________ than the other chambers. 2. The ____________________ are the pumping chambers. They are _______________ and ____________________, and pump blood out of the ______________ to either the lungs or the body. 2.Blood vessels: A. Arteries carry blood ____________ from the heart. (A= artery, A= away) The ______________ is the largest artery and comes directly out of the _______________ and then branches into _____________ which go to the whole body. Arteries carry __________________ blood, except for the ________________ arteries which go to the ______________. Arteries have ________________ which contract every time the heart beats. This bumping feeling is the ___________. atriaatrium smallerthinner ventricles largemuscular heart away aorta heart arteries oxygenated pulmonary lungs muscles pulse

5. B. Veins carry blood ______ the heart. They have one-way ______________ that keep blood moving toward the heart. Blood in veins carries __________ _____________ from the cells and is low in ______________. The one vein that carries oxygenated blood is the __________________ ____________ which leads from the ____________ to the _____________. The largest veins in the body are the ___________ ____________. C.Capillaries – Arteries continue to branch, getting smaller and smaller until they are ________ _________ ____________. Food and oxygen can then _______________ out of the cells and back into the blood vessels, which are now called ___________ and direct the blood back to the _______________. The intersection of the artery and vein where this diffusion takes place is a ____________________. tovalves carbon dioxideoxygen pulmonary veinlungs heart vena cavas one cell thick diffuse veins heart capillary

6. Flow of blood through the circulatory system: ____________ -> __________ _________ -> ___________ _____________ -> ___________ ______________ -> _________________ _______________ -> ______________ -> _________________ _____________ -> __________ __________ -> ____________ _____________ -> __________________ -> _________________ 3.Blood – Blood consists of _______ _______ ___________, __________ ___________ ___________, _____________, and ___________________. A. Red blood cells contain ________________, a chemical that carries _______________ and turns red, and carries ___________ ___________ and turns purplish red. B. White blood cells fight _____________, ________, and other body _______________. C. Platelets are cell _______________ that help ___________ blood. bodyvena cavaright atrium right ventriclepulmonary arteries lungspulmonary veins left atrium left ventricleaortabody red blood cells white blood cells platelets plasma hemoglobin oxygen carbon dioxide bacteria viruses invaders fragments clot

7. The Lymphatic System 1.Lymph is the _______________ made up of ___________, __________ _____________, and ______________________ (cells like white blood cells) and is found between cells. 2.The lymphatic system consists of a network of vessels that pick up lymph through _____________________ which join with larger vessels that drain into large _________ ___________ near the heart. Before being added to the blood, the lymph is filtered in ____________ ____________. One well known lymph node is the _________________, found in the back of the throat, which catch micro-organisms. The largest lymph node is the ______________ which filters blood, breaks down old, worn out blood cells, and contains cells that engulf and destroy ______________. The ______________ is another lymph organ that produces _________________________. fluid water dissolved substances lymphocytes capillaries veins neck lymph nodes tonsils spleen bacteria thymus lymphocytes

8. 3.Lymphocytes are a type of ____________ __________ ____________ that engulf __________________________________. 4.Lymph is circulated through the body by the action of _____________ and _________________ muscles. In the morning, you _________________ your arms and legs which gets your ______________ moving. white blood cell microorganisms voluntary involuntarystretch lymph
