thick walled, muscular, flexible tubes that carry oxygenated blood away from the heart to the capillaries throughout the body.

are minute, thin walled blood vessels that connect smaller arteries to the veins.

controls steady circulation of blood through the body by means of heart & blood vessels.

1. referred to as the body’s pump, is a muscular cone shaped organ about the size of a closed fist.
2. It is enclosed in a membrane known as the pericardium.
3. It normally beats about 72-80 times a minute.

constant & continued circulation from the time it leaves the heartuntil it return.

- process of blood circulation from heart to lungs to be

  purified

circulation of blood from the heart throughout the body & back again to the heart.

tube like structures that transport blood to & from the heart & then on to various tissues of the body.

 a nutritive fluid circulating through the circulatory system.

 thin walled blood vessels that are less elastic than arteries.

- they contain cuplike valves to prevent backflow & carry

  impure blood fom the various capillaries back to the

  heart & lungs.

carry oxygen from the lungs to the body cells.

- produced in the bone marrow, contain 

  hemoglobin & have no nucleus.

 perform the function of destroying disease-causing germs.

aid in the formation of clots

-         fluid part of blood in which the rbc’s, wbc’s, & platelets flow.

-   fluid part of the blood & lymph that carries food & secretions to the cells & CO2 from the cells

iron containing protein in rbc's that binds to oxygen.

- gives blood its bright red color.

exchange of CO2 for O as blood passes through lungs & w/the exchange of oxygen for CO2 as blood circulates throughout the body.

-         Brighter red in arteries (due to oxygen content), darker red in veins (due to CO2 content), except in pulmonary artery color change.

-         Carries H2O, oxygen, food & secretions to all cells of body.

-         Carries away CO2 & waste products eliminated through the lungs, skin, kidneys & large intestine

-         Helps equalize body temp.

-         Aids in protecting body from harmful bacteria & infections through the actions of wbc’s.

-         Closes injured minute blood vessels by forming clots.

-         Is composed of approx 80% water.

-         Norm temp = 98.6°F/36°C

-         Salty & sticky

          -         Brighter red in arteries (due to oxygen content), darker red in veins (due to CO2 content), except in pulmonary artery color change.

- The human body has 8-9 pints.

-Contributes approx. 1/20 of body’s weight.

The interior of the heart consists of 4 chambers:

1. the upper thin walled chambers are the rt & lt atrium.
2. the lower thick walled chambers are the rt & lt ventricles.

One of the two upper chambers of the heart through which blood is pumped to the ventricles.
