Circulatory system Flashcards
erythrocytes
erythrocytes: red blood cells
leucocytes
leucocytes: white blood cells
plasma
plasma: the yellowish, liquid part of blood that contains water, minerals, food and wastes from cells
red blood cells
red blood cells: living cells in the blood that transport oxygen to all other living cells in the body
haemoglobin
haemoglobin: the red pigment in red blood cells that carries oxygen
oxyhaemoglobin
oxyhaemoglobin: haemoglobin with oxygen molecules attached
white blood cells
white blood cells: living cells that fight bacteria and viruses as part of the human body’s immune system
platelets
platelets: small bodies involved in blood clotting. They are responsible for healing by clumping together around a wound.
circulatory system
circulatory system: the body system that circulates oxygen in the blood to all the cells of the body. The circulatory system consists of the heart, the blood vessels and blood.
arteries
arteries: hollow tubes (vessels) with thick walls carrying blood pumped from the heart to other body parts
