_Circulatory System_
| Question | Answer |
|---|---|
| What is the function of the Circulatory System? | Supplies a continuous amount of oxygen and nutrients throughout the body. Also works with excretory system to remove wastes. |
| -Major organ of this system -Made of cardiac tissue -Causes blood to flow through the body by it’s pumping action. -Made of cardiac muscle -4 Chambers a) 2 upper and 2 lower -Blood flows in one direction a) From atrium to ventricle to a blood | The heart |
| -Carry blood that has oxygen and nutrients to all parts of the body. -Carry blood away from the heart. | Arteries |
| Carry waste products from all parts back to the heart. | Veins |
| -Very small vessels where oxygen and nutrients leave the blood and go into the cells and carbon dioxide and other waste products enter the blood from the cells. | Capillaries |
| -Composed of: a) Red blood cells b) White blood cells c) Platelets d) Plasma | Blood |
| -Atherosclerosis -Hyperextension -Heart Failure | Cardiovascular Disease |
| -Erythrocytes -Carry oxygen throughout the body -Look like flattened basketballs -Carry hemoglobin- what gives blood the red color and delivers oxygen to all parts of the body. | Red Blood Cells |
| -Leukocytes -1% of our blood -Bigger than red blood cells -NOT floating around when you are not healthy. | White Blood Cells |
| -Thrombocytes -1% of our blood -Tiny round cells that makes sure you don’t bleed too much when you get cut. | Platelets |
| -Yellowish liquid carrying important nutrients, hormones, and proteins. -Carries away cellular wastes -54% of our blood | Plasma |
| -Right Atrium a) An atrium is an entrance room... it collects blood that is poor in oxygen and sends it to the right ventricle. | Right Atrium |
| -Right ventricle a) This ventricle pumps the deoxygenated blood to the lungs so it can get oxygen through the alveoli. | Right Ventricle |
| -Left atrium a) Collects oxygenated blood from the lungs and sends it to the right ventricle. | Left Atrium |
| -Left ventricle a) The ventricle that has the thickest muscle wall so it can pump oxygenated blood to every part of the body. | Left Ventricle |
