Reading List

Here is a (basic) reading list. The descriptions are simply the initial sentences (complete with links and some stylistic markup) from each Wikipedia page. Note that there is no exact correspondence between links found in the descriptions and reading list entries.


Arteries (from Greek ἀρτηρία (artēria), meaning "windpipe, artery") are blood vessels that carry blood away from the heart.


Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

Blood flow

Blood flow is the continuous circulation of blood in the cardiovascular system.

Blood vessel

The blood vessels are the part of the circulatory system that transports blood throughout the human body.


Capillaries (/ˈkæpɨlɛriz/ in US; /kəˈpɪləriz/ in UK) are the smallest of a body's blood vessels and are parts of its microcirculation.

Cardiac cycle

The cardiac cycle refers to a complete heartbeat from its generation to the beginning of the next beat, and so includes the diastole, the systole, and the intervening pause.

Circulatory system

The circulatory system, also called the cardiovascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from cells in the body to nourish it and help to fight diseases, stabilize body temperature and pH, and to maintain homeostasis.


The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system.

Human lung

The human lungs are the organs of respiration.


Microcirculation is the circulation of the blood in the smallest blood vessels, present in the vasculature embedded within organ tissues.

Red blood cell

Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O2) to the body tissues -- via blood flow through the circulatory system.


In the circulatory system, veins (from the Latin vena) are blood vessels that carry blood toward the heart.

White blood cell

White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
