Anatomy of Circulatory System

Anatomy 

What are the circulatory system  corridor?  

The  corridor of your circulatory system are your   

Heart, a muscular organ that pumps blood throughout your body.  

Blood vessels, which include your  highways,  modes and capillaries.  

Blood, made up of red and white blood cells, tube and platelets.  

What are the circulatory system circuits?  

Your circulatory system has three circuits. Blood circulates through your heart and through these circuits in a  nonstop pattern   

The pulmonary circuit This circuit carries blood without oxygen from the heart to the lungs. The pulmonary  modes return oxygenated blood to the heart.  

The systemic circuit In this circuit, blood with oxygen, nutrients and hormones  peregrination from the heart to the rest of the body. In the  modes, the blood picks up waste products as the body uses up the oxygen, nutrients and hormones.  

The coronary circuit Coronary refers to your heart’s  highways. This circuit provides the heart muscle with oxygenated blood. The coronary circuit  also returns oxygen-poor blood to the heart’s right upper chamber( patio) to  shoot to the lungs for oxygen.  

What are the types of blood vessels?  

There are three main types of blood vessels   highways highways are thin, muscular tubes that carry oxygenated blood down from the heart and to every part of your body. 

Arteries The aorta is the body’s largest  roadway. It starts at the heart and travels up the  casket(  thrusting aorta) and  also down into the stomach( descending aorta). The coronary  highways branch off the aorta, which  also fan  into  lower  highways( arterioles) as they get  further from your heart. 

Veins These blood vessels return oxygen- depleted blood to the heart. modes start small( venules) and get larger as they approach your heart. Two central  modes deliver blood to your heart. The superior vena cava carries blood from the upper body( head and arms) to the heart. The inferior vena cava brings blood up from the lower body( stomach, pelvis and legs) to the heart. modes in the legs have  faucets to keep blood from flowing backward.  

Capillaries These blood vessels connect  veritably small  highways( arterioles) and  modes( venules). Capillaries have thin walls that allow oxygen, carbon dioxide, nutrients and waste products to pass into and out of cells.
