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.
Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [3]

The cortex mainly functions to produce tension under the cell membrane, allowing the cell to change shape. [12] This is primarily accomplished through myosin II motors, which pull on the filaments to generate stress. [12] These changes in tension are required for the cell to change its shape as it undergoes cell migration and cell division. [12]
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 ...
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).

A typical 105-key computer keyboard, consisting of sections with different types of keys. A computer keyboard consists of alphanumeric or character keys for typing, modifier keys for altering the functions of other keys, [1] navigation keys for moving the text cursor on the screen, function keys and system command keys—such as Esc and Break—for special actions, and often a numeric keypad ...
