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 |
