What does the transport system do? Carries O 2, CO 2, nutrients, hormones, wastes, cells of the immune system Regulates body temp.
Circulatory System Also known as the Cardiovascular System. It carries needed substances to cells and carries waste products away from cells.
The Heart – pumps blood through body
Inside the heart
Blood Vessels Arteries – carry blood away from heart – thick round muscular walls- no valves
Blood Vessels Veins – carry blood to the heart – has valves to prevent backflow – thin flattened shape
Blood Vessels Capillaries – one cell thick
What’s in blood? Plasma –carries nutrients, wastes, and water Red Blood Cells – carry oxygen and carbon dioxide White Blood Cells – fight infections Platelets – help with blood clotting
How do RBC’s carry Oxygen? Hemoglobin – a protein found on RBC attaches itself to both oxygen and carbon dioxide
Pulmonary Circulation Blood flows from the heart to the lungs where it picks up O 2 and loses CO 2 and water vapor
Artery Transports blood away from the heart. Very Muscular Very Elastic Thick Muscle Walls Aorta Largest Artery Carries oxygenated blood
Veins Transports blood toward the Heart Thinner walls Valves Prevents backflow Carries deoxygenated blood
Capillaries One celled microscopic blood vessels Connect Arteries Veins
Heart Muscular organ pumps blood throughout the body Valve flap of tissue that prevents blood from flowing backwards.
Atrium 2 upper chambers, receive blood that comes into the heart
Ventricle 2 lower chambers, pumps blood out of heart
Pericardium Covers and protects the heart
What are the different types of molecules that are transported throughout the circulatory system?
Molecules that travel through Circ. Nutrients from digested food O 2 from the lungs Metabolic wastes (CO 2 )
Molecules that travel through Circ. Hormones help coordinate activities in body Heat blood vessels constrict or relax
Regulation of Heartbeat Pacemaker located in the right atrium, sends out signals that make the heart muscle contract. It receives messages about how much oxygen is present
A “Real Pacemaker”
High Blood Pressure Disease caused when blood pressure in the arteries is increased by stress, diet, heredity, smoking, & aging.
Stroke When an area of the brain dies because the area didn’t receive enough O 2
Heart Attack Symptoms sharp, crushing, squeezing pain in the chest, cold sweats, nausea, limb numbness An area of the heart muscle dies and stops working
Coronary Thrombosis Type of heart attack caused by blockage in one of the arteries that carry blood to the heart. Blockage of blood flow to the heart, damaged from lack of oxygen
Leukemia Form of cancer in which bone marrow makes too many white blood cells
Anemia When the blood doesn’t have enough hemoglobin or RBC causing body cells to not receive enough O 2
Arteriosclerosis Fatty plaque builds up on wall of artery blocking normal blood flow
Amazing Heart Facts Your heart is about the same size as your fist. An average adult body contains about f five quarts of blood.
By the time you turn 70, your heart will have beat some two- and-a-half billion times (figuring on an average of 70 beats per minute.)
The risk of heart attack is higher on Monday than any other day of the week. Each square inch of human skin consists of twenty feet of blood vessels.
All the blood vessels in the body joined end to end would stretch 62,000 miles or two and a half times around the earth.
1.The heart circulates the body's blood supply about 1,000 times each day. 2. The heart pumps the equivalent of 5,000 to 6,000 quarts of blood each day.

What is the Circulatory System?
3.2 Circulatory System.
The function of the circulatory system is to transport substances such as gases (O 2, CO 2 ), nutrients/wastes, hormones, immune system. It is also.

Circulatory System Mrs. Degl.
Circulatory system made up of 3 parts organ heart tissues & cells blood vessels arteries veins capillaries blood red blood cells plasma.
The Circulatory System /biology/the-human- body/circulatory-system/
The Circulatory System. The human heart beats more than 2.5 billion times in an average lifetime. The heart produces enough pressure each time it pumps.
