Venous blood is deoxygenated blood which travels from the peripheral blood vessels, through the venous system into the right atrium of the heart. Deoxygenated blood is then pumped by the right ventricle to the lungs via the pulmonary artery which is divided in two branches, left and right to the left and right lungs respectively.
Arterial blood is the oxygenated blood in the circulatory system found in the pulmonary vein, the left chambers of the heart, and in the arteries. [1] It is bright red in color, while venous blood is dark red in color (but looks purple through the translucent skin). It is the contralateral term to venous blood. [citation needed]
The formed elements are the two types of blood cell or corpuscle – the red blood cells, (erythrocytes) and white blood cells (leukocytes), and the cell fragments called platelets [12] that are involved in clotting. By volume, the red blood cells constitute about 45% of whole blood, the plasma about 54.3%, and white cells about 0.7%.
Blood vessels function to transport blood to an animal's body tissues. In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. Blood vessels also circulate blood throughout the circulatory system.
This blood vessel is called your aorta. An aortic aneurysm often doesn’t cause symptoms, but it can lead to severe, sudden bleeding from a ruptured aneurysm. A ruptured aneurysm has a high risk ...
The colour blood red is a dark shade of the colour red meant to resemble the colour of human blood (which is composed of oxygenated red erythrocytes, white leukocytes, and yellow blood plasma). [2] It is the iron in hemoglobin specifically that gives blood its red colour.
Movat's stain is a pentachrome stain originally developed by Henry Zoltan Movat (1923–1995), a Hungarian-Canadian Pathologist in Toronto [1] in 1955 to highlight the various constituents of connective tissue, especially cardiovascular tissue, by five colors in a single stained slide. [2]
The inferior vena cava is the lower ("inferior") of the two venae cavae, the two large veins that carry deoxygenated blood from the body to the right atrium of the heart: the inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of
