Ch. 7.8 Circulatory System Key Terms
What is aortic valve?
aortic valve is located between the left ventricle and the aorta, the largest artery in the body.
What is circulatory system?
The circulatory system, also known as the cardiovascular system, is often referred to as the "transportation" system of the body.
What is left atrium?
The left atrium receives oxygenated blood from the lungs.
What is Pericardium?
The pericardium is a double-layered membrane, or sac, that covers the outside of the heart.
What is Septum?
The septum is a muscular wall that separates the heart into a right side and a left side.
What is Arrhythmias?
Arrhythmias are abnormal heart rhythms and can be mild to life threatening.
What is Diastole?
The cycle consists of a brief period of rest, called diastole
What is left ventricle?
left ventricle receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells.
What is Plasma?
Blood is made of the fluid called plasma
What is Systole?
The cycle consists of a brief period of rest, called diastole, followed by a period of ventricular contraction, called systole
What is Blood?
-a vital bodily fluid that circulates through your arteries and veins, delivering oxygen and nutrients while carrying away waste products.
What is Endocardium?
endocardium is a smooth layer of cells that lines the inside of the heart and is continuous with the inside of blood vessels. It allows for the smooth flow of blood.
What is Leukocytes?
Leukocytes, or white blood cells
What is pulmonary valve?
The pulmonary valve is located between the right ventricle and the pulmonary artery, a blood vessel that carries blood to the lungs.
What is Thrombocytes?
Thrombocytes, also called platelets, are usually described as fragments or pieces of cells because they lack nuclei and vary in shape and size.
What is Arteries?
carry blood away from the heart.
What is Erythrocytes?
erythrocytes, or red blood cells, are produced in the red bone marrow at a rate of about one million per minute.
What is mitral valve?
mitral valve is located between the left atrium and left ventricle
What is right atrium?
The right atrium receives blood as it returns from the body cells.
What is tricuspid valve?
The tricuspid valve is located between the right atrium and the right ventricle.
What is Capillaries?
Capillaries are also connected to the venous system, and one-way venous valves allow blood flow return to the heart.
What is Hemoglobin?
Hemoglobin carries both oxygen and carbon
What is Myocardium?
The thickest layer is the myocardium
What is right ventricle?
The right ventricle receives blood from the right atrium and pumps the blood into the pulmonary artery, which carries the blood to the lungs for oxygen.
What is Veins?
This oxygenated blood is then carried to the left side of the heart by the pulmonary veins.
