Circulatory and Lymphatic Systems

The circulatory system moves substances in to and from ____________ where theyare _______________ or __________________, responding to changing demands.The circulatory system includes the _______________, _________________, ___________________, ________________, and ___________________.

1. The Heart The heart is a __________________ _________________ in your chest. Itis made up of ____ chambers. The 2 upper chambers are called_____________ and the 2 lower ones are called ____________________. A ________________ separates each _____________ from the ____________________ below it so that the blood flows in only onedirection. Your heart is a “2-pump” system.

The Right Side: The ____________ ___________-filled blood from thebody cells is brought into the __________ __________ through the _________ ___________ (the largest veins in the body). From the rightatrium it goes down through a _____________ into the ______________________________ below it. This then pumps the blood through the_________________ ________________ to the lungs where it will dropoff the _____________ _______________ and pick up ________________.The Left Side: The ________________-rich blood then goes through the ________________ _____________ to the ___________ _____________. From there, the blood goes down through a _____________ into the

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 ___________.

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 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 filtersblood, breaks down old, worn outblood cells, and contains cells thatengulf and destroy ______________.The ______________ is anotherlymph organ that produces_________________________.
