Circulatory System
The circulatory system carries energy and blood everywhere in your body. The system is made up of a network of highways that transports nutrients and blood. Your heart pumps blood into your body, allowing a person to function. This system regulates body heat in a process called homeostasis. Blood vessels make up the circulatory system such as arteries, capillaries, and veins.
-Arteries are blood vessels that carry blood away from your heart.
- Capillaries are tiny vessels that allow the exchange of materials between the blood and other parts of the body.
- Veins are larger in diameter than arteries; most veins have a one way valve that keeps blood from flowing backward.
-Plasma fills the blood and acts as a solvent to dissolve other materials called solutes.
-Red blood cells are erythrocytes and their main function is to carry oxygen. The red blood cells get their color from hemoglobin, an iron containing protein that picks up oxygen in your lungs, and transports it to the tissues in the body.
-White blood cells defend the body against disease while a pathogen is a disease that kills blood cells making you sick.
-Platelets form when certain large cells in bone marrow regularly pinch off bits of their cytoplasm. When you get a cut your platelets clump together and seal the wound.

Respiratory System
As blood travels through your body it provides oxygen to the bodies cells allowing cellular respiration. Your body consists of many parts that help this system work. The nose, mouth, pharynx, larynx, trachea, bronchioles, and lungs all work together to make this system work.
Nose/Mouth- Either one of these parts allow you to breath in and out air
Pharynx- Carries warm moistened air to the trachea
Larynx- Voice box the produces sound, located at the upper end of the trachea
Trachea- Long narrow tube, also called the wind pipe
Bronchioles- Terminate by entering little clusters of air sacs called alveoli
Lungs- Picks up oxygen and releases carbon dioxide
