[1] [2] Some of the blood entering the right atrium does not pass directly to the left atrium through the foramen ovale, but enters the right ventricle. This blood consists of oxygenated placental blood and deoxygenated blood returning from the fetal circulation. [2] This blood is pumped into the pulmonary artery. At the pulmonary artery, it is ...
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
It makes up about 55% of the body's total blood volume. [1] It is the intravascular part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume), and contains important dissolved proteins (6–8%; e.g., serum albumins, globulins, and fibrinogen), [2] glucose, clotting factors, electrolytes (Na +, Ca 2+, Mg 2+
Red blood cells or erythrocytes primarily carry oxygen and collect carbon dioxide through the use of hemoglobin. [2] Hemoglobin is an iron -containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled.

After the cord is clamped and cut, the newborn wears a plastic clip on the navel area until the compressed region of the cord has dried and sealed sufficiently. The length of umbilical left attached to the newborn varies by practice; in most hospital settings the length of cord left attached after clamping and cutting is minimal.
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
Fresh frozen plasma is made up of a complex mixture of water, proteins, carbohydrates, fats, and vitamins. [1] When frozen it lasts about a year. [1] Plasma first came into medical use during the Second World War. [1] It is on the World Health Organization's List of Essential Medicines. [7] In the United Kingdom it costs about £30 per unit.

Systole (/ ˈ s ɪ s t əl i / SIST-ə-lee) is the part of the cardiac cycle during which some chambers of the heart contract after refilling with blood. [1] Its contrasting phase is diastole , the relaxed phase of the cardiac cycle when the chambers of the heart are refilling with blood.
