Trace the path of a red blood cell

What is the path blood takes in the circulatory system?

As the right ventricle contracts, it forces the deoxygenated blood through the pulmonary semilunar valve and into the pulmonary artery. S emilunar means half-moon and refers to the shape of the valve. Note that this is the only artery in the body that contains deoxygenated blood; all other arteries contain oxygenated blood. The semilunar valve keeps blood from flowing back into the right ventricle once it is in the pulmonary artery.

The pulmonary artery carries the blood that is very low in oxygen to the lungs , where it becomes oxygenated. Freshly oxygenated blood returns to the heart via the pulmonary veins. Note that these are the only veins in the body that contain oxygenated blood; all other veins contain deoxygenated blood.

The pulmonary veins enter the left atrium.

When the left atrium relaxes, the oxygenated blood drains into the left ventricle through the left AV valve. This valve is also called the bicuspid valve because it has only two flaps in its structure. Now the heart really squeezes. As the left ventricle contracts, the oxygenated blood is pumped into the main artery of the body — the aorta. To get to the aorta, blood passes through the aortic semilunar valve , which serves to keep blood flowing from the aorta back into the left ventricle. The aorta branches into other arteries, which then branch into smaller arterioles. The arterioles meet up with capillaries, which are the blood vessels where oxygen is exchanged for carbon dioxide.

Capillaries bridge the smallest of the arteries and the smallest of the veins. Trace the path that red blood cell would take from the. Share this conversation. Answered in 17 hours by:. M Swenson , Third-year Medical Student. Satisfied Customers: Experience: EMT for over eight years. DearCustomer There are a number of paths that a red blood cell could take, since we have so many arteries and veins in our body.

Here is one possible route: 1 The blood cell enters a dorsal metatarsal vein, then travels up to the heart through the: 2 Great Saphenous vein 3 Femoral Vein 4 External iliac vein 5 Common iliac vein 6 Inferior vena cava 6 Right atrium of the heart 7 Right ventricle of the heart 8 pulmonary artery 9 pulmonary arterioles 10 pulmonary capillaries where oxygen and carbon dioxide are exchanged 11 pulmonary venules 12 pulmonary vein 13 Left atrium of the heart 14 Left ventricle of the heart 15 aorta 16 Common iliac artery 17 External iliac artery 18 Femoral artery 19 popliteal artery 20 posterior tibial artery 21 Medial plantar artery 22 first proper plantar digital branch of medial plantar artery, which goes to the big toe I hope this was what what you were looking for!

As shown in the image above there are actually two circulatory systems in the body. The systemic circulatory system provides food and nutrients to all the organs, tissues and cells in the body. The pulmonary system is the path blood takes through the lungs receiving fresh oxygen and releasing carbon dioxide.

The oxygen in the lungs binds to hemoglobin which is contained in red blood cells. Blood circulation begins when the heart relaxes between heart beats.

Blood then flows from both upper atrium's left atrium and right atrium into the two lower chambers left and right ventricles which then expand. Blood is then ejected ejection phase when the ventricles contract and pump the blood into the arteries. In systemic circulation the left ventricle which is the largest and most muscular chamber pumps blood containing oxygen in the aorta the largest artery in the body.

Blood then branches from the aorta to smaller arteries in the body.
