Heart Anatomy
The heart is the organ that helps supply blood and oxygen to all parts of the body. Heart anatomy focuses on the structure and function of this amazing organ.
The Heart
The heart is the organ that supplies blood and oxygen to all parts of the body.
Anatomy of the Heart: Aorta
Information and resources pertaining to the aorta of the heart.
Anatomy of the Heart: Pericardium
Information and resources pertaining to the pericardium of the human heart.
Anatomy of the Heart: Valves
Information and resources pertaining to the human heart valves.
Atria of the Heart
The atria of the heart receive blood returning to the heart from other areas of the body.
Ventricles of the Heart
The ventricles of the heart function to pump blood to the entire body.
Cardiac Cycle
The cardiac cycle is the sequence of events that occurs when the heart beats.
The Spinal Cord
The spinal cord is a cylindrical shaped bundle of nerve fibers that convey messages to and from the brain. The spongy spinal cord is protected by the irregular shaped bones of the spinal column called vertebrae.
The Lungs
The lungs are the organs responsible for breathing, the alternate inhalation and exhalation of air. The heart and lungs work together to provide oxygen to the cells of the body.
Blood Vessels
Blood vessels are intricate networks of hollow tubes that transport blood throughout the entire body.
Vena Cavae
The superior vena cava and inferior vena cava are the two largest veins in the body.
Brachiocephalic Artery
The brachiocephalic artery supplies oxygenated blood from the aorta to the head, neck and arm regions of the body.
Microcirculation
Microcirculation deals with the circulation of blood from the heart to arteries, capillaries and veins.
Capillary
A capillary is an extremely small blood vessel located within the tissues of the body.
Vein
A vein is an elastic blood vessel that transports blood from various regions of the body to the heart. Veins can be categorized into pulmonary, systemic, superficial, and deep veins.
Artery
An artery is an elastic blood vessel that transports blood away from the heart. Pulmonary and systemic arteries are two main types of arteries.
Pulmonary Artery
Information and resources pertaining to the pulmonary artery of the heart.
Cerebral Cortex
The cerebral cortex is the layer of the brain often referred to as gray matter. It is the outer portion of the cerebrum.
Amygdala
The amygdala is an almond shaped mass of nuclei located deep within the temporal lobe of the brain.
