Life Science Mr. Petriccione
The circulatory system carries blood to every part of the body
It works with the respiratory system It uses a network of transport tubes, acting like a set of highways and roads.
Arteries-carry oxygen rich blood to the cells Veins-carry carbon dioxide blood away from cells Capillaries-exchanges oxygen and carbon dioxide between cells
The Heart
The heart moves blood through four chambers
What do arteries do?
It enters the right atrium from the vena cava
It goes through a valve to the right ventricle The valve prevents blood from flowing back
It goes to the pulmonary artery that moves blood to the lungs
It picks up oxygen at the lungs
It returns to the heart through the pulmonary vein, entering the left atrium
From the left atrium, it passes through another valve to the left ventricle The valve prevents blood from flowing back
From the left ventricle, it flows to the aorta and out to the body
From the Aorta, it moves to arteries and then to capillaries
From the capillaries, it drops off oxygen and nutrients at the cells
After dropping off the oxygen, the blood moves from the capillaries to the veins to the vena cava
What are the four parts (chambers) of the heart?
The muscle cells of the heart shorten, causing the muscle fibers to shorten, and the heart muscle to contract
Use your own paper What does a valve do?
Blood transports oxygen and nutrients to other parts of the body
Liquid part of blood
Carry oxygen, using hemoglobin
Binds oxygen to the red blood cells, using iron
Help the body fight infection
Help in clotting, to stop bleeding
Who has ever heard of it? What is it?
Shape of Blood Cells is sickle-shaped What is a sickle?
Shortened life expectancy Blood clots are more common because the sickle shape lumps together Oddly, people with sickle cell anemia are immune from malaria It is a genetic disorder
