Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body. (powered by the heart)
the muscle that pumps blood received from veins into arteries throughout the body. It is the size of your fist, located slightly left of the center of your chest, and has four chambers.
fluid form of connective tissue that has three functions; regulation, protection, and transportation. Transports oxygen from lungs, nutrients from digestive system and fat cells, and hormones, maintains homeostasis, regulates body temp.
transports nutrients, proteins, and hormones to the parts of the body that need it. Plasma also helps remove waste from the body and assists the movement of all the elements of blood through the circulatory system.
a tube like structure carrying blood through the tissues and organs (such as a vein, artery, or capillary)
blood vessel that carries oxygenated blood away from the heart to the body
a small branch of an artery leading into capillaries
tiny blood vessels that connect the smallest arteries (arterioles) to the smallest veins (venules)
blood vessel that carries blood toward the heart
a very small vein, that collects blood from the capillaries
outermost layer surrounding the heart
double wall sac; consisting of two layers, visceral and parietal; the space between the layers is the pericardial cavity.
layer between the fibrous pericardium and visceral pericardium. It is continuous with fibrous pericardium and provides an additional layer of insulation for the heart.
the inner layer of the serous pericardium, which is in contact with the heart and roots of the great vessels. (epicardium)
a serous membrane that forms the innermost layer of the pericardium and the outer surface of the heart
muscle tissue of the heart
innermost lining of the heart
an anatomical cavity or passage (a chamber of the heart that receives blood from the veins and moves it into the ventricles)
a chamber of the heart which receives blood from a corresponding atrium and from which blood is forced into the arteries
the wall that separates right from left atrium.
inter ventricular septum
the wall that separates the right and left ventricles of the heart
right upper chamber that receives deoxygenated blood from the body from the venacava and pumps it into the right ventricle, thus sending it to the lungs to be oxygenated.
superior vena cava
large vein that receives deoxygenated blood from the head, neck, upper extremities, and delivers it to the right atrium of the heart.
inferior vena cava
large vein that carries the deoxygenated blood from the lower part of the body to the heart.
the right atrium passes blood through the tricuspid valve and into the right ventricle, which pumps the blood through the pulmonary valve and pulmonary artery to the lungs.
includes the tricuspid and bicuspid valve that connect the atrium to the ventricles
a valve located between the right atrium and the right ventricle; consists of three triangular membranous flaps.
sequence of events when the heart beats; it is completed when the heart chambers are filled with blood and then blood is pumped out of the heart. 2 phases: in the diastole phase, the heart ventricles are relaxed and the heart fills with blood. In the systole phase, the ventricles contract, pumping blood out of the heart.
the blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. (top number)
the time period when the heart is in a state of relaxation and dilatation (expansion and minimal arterial pressure) (bottom number)
the artery carrying blood from the right ventricle of the heart to the lungs for oxygenation
transports deoxygenated blood to the lungs to absorb oxygen where then the oxygenated blood flows back to the heart.
upper right chamber; receives oxygenated blood from the lungs and pumps it down into the left ventricle, which delivers it to the body.
left lower chamber; receives oxygenated blood from the left atrium and pumps it out under high pressure to tissues all over the body
same as mitral
a valve in the heart that is situated between the left atrium and the left ventricle. It allows blood to flow from the left atrium into the left ventricle (also known as bicuspid valve)
a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck
system of blood vessels that forms a closed circuit between the heart and the lungs where blood is oxygenated.
this is a diagnostic test that uses x-rays to take pictures of your blood vessels.
this is usually a barium or iodine dye that is injected into the area under investigation. It increases the contrast of an image on an x-ray.
this circulation carries oxygenated blood from the heart to the body and returns deoxygenated blood back to the heart
the aorta (main blood supplier to the body) branches off into two main coronary blood vessels. These coronary arteries supply oxygenated blood to the entire heart muscle.
a surgical connection between two structures. Typically means a connection that is created between tubular structures, such as blood vessels.
structural formations found between the myocardial cells of the heart. They bond cardiac muscle cells together and transmit signals between cells.
