2 The function and importance of the circulatory system. Transportation of materials. Contains cells that fight infection. Helps stabilize the pH and ionic concentration of the body fluids. It helps maintain body temperature by transporting heat. This is particularly important in homeothermic animals such as birds and mammals.

3 Blood vessels. The three types of blood vessels are arteries, capillaries, and veins. Each blood vessel consists of a layered wall surrounding a central blood-containing space, or lumen. Blood vessels carry the blood throughout the body and supply nutrients to everything.

4 Heart! The route of blood  through our heart.

5 Composition of blood.

6 Erythrocytes As you can see, the structures and functions of erythrocytes, are red blood cells, white blood cells, and platelets.

7 Open vs Closed Systems An open circulatory system is found in all arthropods. The blood is propelled through the body by a tubular heart and collected in areas called sinuses. A closed circulation contains a heart connected to a mass of connected blood vessels that allows the blood to circulate throughout the body without leaving the circulatory pathway.

8 Fish Circulation A fish has a closed circulatory system.

9 Amphibian Circulation Amphibians have a closed circulatory system.

10 Reptile Circulation Reptiles have a closed system.

11 Mammal Circulation Mammals have closed circulatory systems!

12 Hypertension Blood pressure is the force of blood pushing against the walls of your arteries. High blood pressure means that your blood is moving through your arteries with a pressure higher than normal. The higher the pressure inside your arteries, the higher your blood pressure numbers will get.

13 Atherosclerosis A disease in which plaque builds up inside your arteries. Then restricts blood flow.
