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 ...
Watermelon is grown in favorable climates from tropical to temperate regions worldwide for its large edible fruit, which is a berry with a hard rind and no internal divisions, and is botanically called a pepo. The sweet, juicy flesh is usually deep red to pink, with many black seeds, although seedless varieties exist.
A feedback loop involving erythropoietin helps regulate the process of erythropoiesis so that, in non-disease states, the production of red blood cells is equal to the destruction of red blood cells and the red blood cell number is sufficient to sustain adequate tissue oxygen levels but not so high as to cause sludging, thrombosis, or stroke ...
Erythrocyte rosetting or E-rosetting is a phenomenon seen through a microscope where red blood cells (erythrocytes) are arranged around a central cell to form a cluster that looks like a flower. The red blood cells surrounding the cell form the petal, while the central cell forms the stigma of the flower shape.
1. This is the Rh-positive blood cell. 2. This is the Rh-negative blood cell. 3. These are the antigens on the Rh-positive blood cell that make it positive. The antigens allow the positive blood cell to attach to specific antibodies. Rh phenotypes are readily identified through the presence or absence of the Rh surface antigens.
Citrullus consists of the following species and subspecies: [2] [3]. Citrullus amarus Schrad. – citron melon; Citrullus colocynthis Schrad. – colocynth; Citrullus ecirrhosus Cogn. – tendril-less melon
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. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40–45% of its volume. Red blood cells are circular ...
The organic compound citrulline is an α-amino acid. [2] Its name is derived from citrullus, the Latin word for watermelon.Although named and described by gastroenterologists since the late 19th century, it was first isolated from watermelon in 1914 by Japanese researchers Yatarō Koga (古賀彌太郎) and Ryō Ōtake (大嶽了) [3] [4] and further codified by Mitsunori Wada of Tokyo ...
