Circulatory system-
Transportation system by which oxygen and nutrients reach the body's cells, and waste materials are carried away. s The circulatory system functions in the delivery of oxygen, nutrient molecules, and hormones and the removal of carbon dioxide, ammonia and other metabolic wastes.
Parts
-blood, bloood vessels, heart, and antibodies.
Arteries- Carry blood away from the heart (oxygen-rich blood)
Veins-Carry blood back to the heart (de-oxygenated)
Capillaries-Connect the arteries and vein
·Capillaries are the points of exchange between the blood and surrounding tissues.
·Materials cross in and out of the capillaries by passing through or between the cells that line the capillary.
- O2 to Co2 Exchange in cells and in respiratory system
Blood
· Carries Oxygen to all part of body
· Carries waste products to kidneys
· Transports nutrients to body cells
· Fight infection and help heal wounds
Red blood cells (45%)- Red Blood Cells contain hemoglobin – a molecule that carries oxygen and carbon dioxide.
White blood cells (<1%)- White blood cells fight bacteria, viruses, and other invaders of your body.
Platelets (<1%)-Platelets (thrombocyctes) are irregularly shaped cell fragments that help clot blood via protein fibers called fibrin.
Plasma (55%)- Plasma - Liquid portion of the blood. Contains clotting factors, hormones, antibodies, dissolved gases, nutrients and waste
