Circulatory System I
The purpose of the circulatory system.
What is to transport materials (nutrients, oxygen, gases, hormones, wastes) around the body?
What is plasma?
Main organ of the circulatory system; pumps blood.
What is the heart?
Gas obtained from the air we breathe in; needed for cell respiration.
Main organs of respiration; we have 2.
What are lungs?
Blood cells that carry oxygen.
What are red blood cells?
Blood vessels that carry blood away from the heart.
What are arteries?
Top chambers of the heart; receive blood
What are atria?
Where air is inhaled; also filters and warms air.
What is the nose?
Large muscle under lungs that contracts and relaxes to allow for inhalation and exhalation
What is the diaphragm?
Blood cells that fight infection and disease.
What are white blood cells?
Blood vessels that return blood to the heart.
What are veins?
Bottom chambers of the heart; pump blood.
What are ventricles?
Also known as the windpipe; this tube conducts air to the lungs.
What is the trachea?
Tubes that branch off of the trachea; one goes to the right lung and the other goes to the left lung.
What are bronchi?
Fragments of blood cells that are involved in clotting.
What are platelets?
Tiny blood vessels that allow for the exchange of materials between blood and nearby cells.
What are capillaries?
Large artery leaving the left ventricle; delivers oxygenated blood to body
What is the aorta?
Small air passageways in the lungs; branch off of the bronchi.
What are bronchioles?
Small "balloons" at the end of bronchioles in the lungs; where gas exchange between the air and capillaries takes place.
Proteins on the surface of red blood cells that determine blood type.
What are antigens?
System that collects leaked fluid and returns it to the circulatory system.
What is the lymphatic system?
Circulatory loop leaving the right side of the heart, going to the lungs, then returning to the left side of the heart.
What is the pulmonary circulation loop?
Process by which oxygen passes from the air in the alveoli to the blood in the capillaries.
What is diffusion?
This covers the trachea during eating or drinking to prevent food from entering it.
What is the epiglottis?
