Anatomy
Study of the structure and parts of the body
Anatomy
Body system that circulates blood throughout the body; main parts are blood, heart, and blood vessels
Circulatory system
Blood cells that defend the body by fighting disease and infection
White blood cells
Liquid tissue that carries substances throughout the body; main parts are plasma, red blood cells, white blood cells, and platelets
Blood
Main organs of the respiratory system; absorb oxygen from the air into the blood and release carbon dioxide from the blood into the air
Lungs
Main organ of the circulatory system; powerful muscle that circulates blood throughout the body
Heart
The continuous flow of blood within the body
Circulation
The pressure of blood against the artery walls
Blood pressure
Smallest unit of any living thing
Cell
Complete well-being of a person; includes the material body and immaterial spirit
Health
Blood cells that absorb oxygen in the lungs and carry it throughout the body
Red blood cells
Body system that brings oxygen into the body and exchanges it with carbon dioxide
Respiratory system
Main muscle of breathing; moves down to inhale and up to exhale
Diaphragm
The process of inhaling (breathing in) and exhaling (breathing out) air
Respiration
Tubes that carry blood throughout the body; arteries, capillaries, and veins
Blood vessels
The expanding of the arteries after each heartbeat; used to measure heart rate
Pulse
Group of cells working together to perform a single function for the body
Tissue
Managing what belongs to someone else as a caretaker
Stewardship
Straw-colored liquid part of blood; makes up over 50% of blood
Plasma
Upper chamber of the heart
Atrium
Windpipe
Trachea
Lower chamber of the heart
Ventricle
Blood vessel that returns blood to the heart
Vein
The amount of air that the lungs can hold
Lung capacity
Structure made of several types of tissue to perform a definite function for a system
Organ
The smallest air tubes in the lungs
Bronchioles
Part of blood that covers open wounds and enables blood to clot
Platelets
Large vein that brings blood from the body to the right atrium of the heart
Vena cava
The air tubes that allow air to enter the lungs
Bronchi
The body's largest artery; receives blood from the left ventricle of the heart; branches into arteries that carry blood to the rest of the body
Aorta
Blood vessel that takes blood away from the heart
Artery
Ability of the body to do strenuous work over long periods of time
Group of organs working together to do a specific job for the body
System
Throat
Pharynx
Special protein that red blood cells use to carry oxygen; contains the mineral iron
Hemoglobin
Larynx
The tiny air sacs in the lungs; thin walls allow the exchange of gases between the air and the blood
Alveoli
Buildup of fatty deposits in the artery
Atherosclerosis
The smallest type of blood vessel; links arteries and veins
Capillary
Wall of muscle that separates the right side of the heart from the left side
Septum
