Ch. 7.8 Circulatory System
What is Aortic valve
Located between the left ventricle and the aorta, the largest artery in the body.
What is Arrhythmias
Abnormal heart rhythms and can be mild to life threatening.
What is Arteries
Carry blood away from the heart.
What is Blood
Flows through the circulatory system, often called a tissue because it contains many kinds of cells.
What is Capillaries
Connect arterioles with venules.
What is Circulatory system
Also known as the cardiovascular system, the “transportation” system of the body.
What is Diastole
A brief period of rest during the cardiac cycle.
What is Endocardium
A smooth layer of cells that lines the inside of the heart and is continuous with the inside of blood vessels.
What is Erythrocytes
Red blood cells, produced in the red bone marrow at a rate of about one million per minute.
What is Hemoglobin
A complex protein composed of the protein molecule called globin and the iron compound called heme.
What is Left atrium
Receives oxygenated blood from the lungs.
What is Left ventricle
Receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells.
What is Leukocytes
White blood cells, not as numerous as erythrocytes, are formed in the bone marrow and lymph tissue and usually live about 3-9 days.
What is Mitral valve
Located between the left atrium and left ventricle.
What is Myocardium
Thickest layer of heart, the muscular middle layer.
What is Pericardium
A double-layered membrane, or sac, that covers the outside of the heart.
What is Plasma
Make of the blood, approximately 90 percent water, with many dissolved, or suspended, substances.
What is Pulmonary valve
Located between the right ventricle and the pulmonary artery, a blood vessel that carries blood to the lungs.
What is Right atrium
Receives blood as it returns from the body cells.
What is Right ventricle
Receives blood from the right atrium and pumps the blood into the pulmonary artery, which carries the blood to the lungs of oxygen.
What is Septum
Muscular wall that separates the heart into a right side and a left side.
What is Systole
The period of ventricular contraction the follows the diastole
What is Thrombocytes
Also called platelets, usually described as fragments or pieces of cells because they lack nuclei and vary in shape and size.
What is Tricuspid valve
Located between the right atrium and the right ventricle.
What is Veins
Blood vessels that carry blood back to the heart.
