1. Circulatory System
Vocabulary

2. Parts of the Blood
54% Plasma – the liquid part of the blood that is mostly water. It contains dissolved nutrients and waste products; such as carbon dioxide.
45% Red Blood Cells – the solid part of the blood that absorbs (takes in) oxygen from the lungs. It also removes the carbon dioxide from cells and returns it to the lungs to remove.
1%↓ White Blood Cells – The solid part of blood that helps the body fight infections. They attack and destroy (kill) viruses and bacteria that enter the body.
1%↓ Platelets – Tiny pieces of blood cells inside membranes. They cause the blood to clot when a vessel is cut and also helps to repair the damaged vessel.

4. Heart Related
Heart – an organ made up of muscle tissue that pumps the blood through the vessels.
Heart Beat – The rhythmic sound from throbbing the heart makes as it pumps the blood through the vessels.
Heart Rate – the number of times the heart beats in a minute.
Pulse – the rhythmic throbbing of arteries produced by the regular contractions of the heart, especially as palpated on the wrist and neck.

6. Vessels
Arteries – Blood vessels that carry the blood away from the heart.
Veins – Blood vessels that return the blood to the heart.
Capillaries – The smallest blood vessel that diffuses (releases, lets go) the oxygen and nutrients to cells and removes the waste from the cells.
Circulatory System – transports oxygen and nutrients through out the body and removes the waste, carbon dioxide.

8. Respiratory System
Vocabulary

9. Respiratory
Respiratory System– the system in which oxygen diffuses into the blood and carbon dioxide diffuses out of the blood.
Lungs– The main organ of the respiratory system. It is a sponge, saclike respiratory organs that function to provide oxygen to the blood and remove carbon dioxide from the blood.
Oxygen– the element that we breathe that is used by the body to produce energy.
Carbon Dioxide – the gas which is exhaled and a waste product formed during respiration that releases energy in the cells.
