Cardiovascular Flashcards
Arteries
The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body.
Blood vessels
Blood vessels are channels that carry blood throughout your body.
Capillaries
Capillaries (CAP-uh-lair-eez) are tiny blood vessels that transport blood, nutrients and oxygen to cells in your organs and body systems.
Deoxygenated
Deoxygenated is defined as oxygen has been removed
Heart
The task of your heart is to pump enough blood to deliver a continuous supply of oxygen and other nutrients to the brain and the other vital organs.
Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8
Oxygenated
Oxygenated chemical compounds contain oxygen as a part of their chemical structure.
Pulmonary circulation
Pulmonary circulation includes a vast network of arteries, veins, and lymphatics that function to exchange blood and other tissue fluids between the heart, the lungs, and back.
Systemic circulation
The systemic circulation provides the functional blood supply to all body tissue. It carries oxygen and nutrients to the cells and picks up carbon dioxide and waste products.
Veins
Veins are blood vessels in humans, and most other animals that carry blood towards the heart.
Size of heart
The heart weighs between 7 and 15 ounces
How many chambers does the heart have?
A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood.
Location of heart
Your heart is located in the front of your chest. It sits slightly behind and to the left of your sternum
Apex
the tip of a pyramidal or rounded structure, such as the lung or the heart
Endocardium
The endocardium is the innermost layer of the heart and lines the chambers and extends over projecting structures such as the valves, chordae tendineae, and papillary muscles.
Myocardium
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle. It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
Pericardium
The pericardium is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly.
Atria
The atrium (Latin: ātrium, lit. ‘entry hall’) is the upper chamber through which blood enters the ventricles of the heart.
Ventricles
each of the two main chambers of the heart, left and right.
Tricuspid valve
The tricuspid valve is on the right side of the heart. It separates the upper and lower chambers, also known as the right atrium and ventricle.
Pulmonary valve
The pulmonary valve is one of four valves that regulate blood flow in the heart. The valve lies between the lower right heart chamber (right ventricle) and the pulmonary artery.
Mitral valve
the valve between the left atrium and the left ventricle of the heart, consisting of two tapered cusps
Aortic valve
The aortic valve—the main outflow valve for the left heart—is the valve between the heart and the body
