Cardiovascular System

Heart

• Fist sized muscular organ that pumps blood

• Small organ that filters toxins from the blood

• Large organ that stores bile for digestion

• Thin-walled organ that absorbs nutrients

Valve

• Flaps that open and close to control the passage of blood

• Muscles that pump blood throughout the body

• Tissues that form the outer layer of the heart

• Cells that produce red blood cells

Artery

• Muscular walled tubes which carries oxygenated blood away from the heart

• Thin-walled vessels that carry deoxygenated blood to the heart

• Smallest blood vessels where gas exchange occurs

• Large vessels that transport lymph throughout the body

Right Atrium

• Heart chamber that receives deoxygenated blood and drives it into the right ventricle.

• Heart chamber that pumps oxygenated blood to the body.

• Heart chamber that receives oxygenated blood from the lungs.

• Heart chamber that regulates blood pressure.

Lungs

• Part of the digestive system; where food is broken down

• Part of the respiratory system; where the O2 and CO2 transfer occurs

• Part of the circulatory system; responsible for blood filtration

• Part of the nervous system; involved in reflex actions

Pulmonary Veins

• Blood vessels that carry oxygenated blood from the lungs to the heart

• Blood vessels that carry deoxygenated blood from the heart to the lungs

• Blood vessels that supply blood to the lungs

• Blood vessels that transport nutrients to the heart

Carbon Dioxide

• A colorless, odorless gas produced by respiration; CO2

• A green gas used in photosynthesis; O2

• A liquid used in refrigeration; H2O

• A solid mineral found in rocks; CaCO3

Left Atrium

• Heart chamber that receives oxygenated blood and drives it into the left ventricle

• Heart chamber that pumps deoxygenated blood to the lungs

• Heart chamber that receives blood from the body

• Heart chamber that regulates blood pressure

Superior Vena Cava

• Carries deoxygenated blood to the right atrium from the upper body veins; largest vein

• Carries oxygenated blood from the lungs to the left atrium

• Transports nutrients from the digestive tract to the liver

• Drains blood from the lower body to the right atrium

Inferior Vena Cava

• Carries deoxygenated blood to the right atrium from the lower body veins; largest vein

• Carries oxygenated blood from the lungs to the heart

• Transports nutrients from the digestive system to the liver

• Drains blood from the upper body to the left atrium
