- What are the 3 components of the circulatory system?
-
-Blood
-Heart
-Blood vessels - What are the 4 types of blood and what do they do?
-
-Red Blood cell. carries oxygen and removes carbon dioxide.
-Plasma. water constituet of blood in which cells are suspended.
-Platlets. Blood clotting and scar/wound healing.
-White blood cell. Neutralise pathagons and their toxins. - what are the 5 types of blood vessels and wha do they do?
-
-veins
-arteries
-capillsries
-arteriole
-venule
The transport blood to and from the heart ensuring all cells and tissues are provided with essential and waste products are removed. - what do the myocordial tissues do?
- They ensure that blood is transported to the body tissues and oxtremetres this create the control pressure for it to be achevied.
- what is the 3 things make up the myocardial tissues?
-
-myocardial. middle layer of the heart.
-Myogenic. orgin of muscle tissue.
-Myocyte. muscular cell - what does the superior vena cava and pulmonary veins do?
-
-superior vena cava carries blood back from the body.
-Pulmonary veins brings blood back from lungs. - What does the right atrium and tricuspid valve do?
-
-the right atrium alows blood to flow through it.
-The tricuspid valve acts as a flap to prevent backflow. - what does the right ventricle and the aorta do?
-
-the right ventricle allows the blood to flow to the lungs.
-the aorta takes blood to the body - what does the pulmonary artery and left atrium do?
-
-pulmonary artery takes blood to the lungs.
-left atrium carries oxygenated blood to body - what does the pulmonary valve and bicuspid valve do?
-
-pulmonary valve contains blood flow from right ventrical to pulmonary arteries.
-bicuspid valve acts as a flap to prevent backflow. - what does the left ventricle and inferior vena cava do?
-
-the left ventricle carries blood to the aorta.
-inferior vena cava brings deoxygenated blood from the body to the heart.
