How is the circulatory system connected with other systems?

   Circulatory system is connected in many ways with other systems.

   Respiratory system:
   Oxygen deprived blood first enters the right atrium, goes past the right articular tricuspid valve into the right ventricle. Then it goes past the semilunar valve into the pulmonary artery, which leads to the lungs. There, the blood picks up oxygen molecules due to hemoglobin and partial pressures. The blood then returns to the left atrium, past the left atricular mitral bicuspid valve and into the left ventricle. There, the blood goes to the systemic circuit, which flows to the rest of the body. Gas exchange passes through capilaries and into/out of the blood.

   Excretory:
   Blood flows to the kidneys, where the nephrons, the functional units of the kindeys. Blood will be filtered throughout the entire nephron. Arteries and veins surround the ascending and descending loop of henle and water and solutes diffuse through both in and out of the loop to regulate the amount of urea excreted and in the blood. More regulation also occurs at the bowman’s capsule and the collecting duct.

   Digestive system:
   Blood flows to the stomach because it is a muscle. The stomach performs both mechanical and chemical digestion, so cells of the stomach require oxygen. This oxygen is delivered via the blood/hemoglobin.

   I know that you get oxygen from the respratory [idk hpw to spell that] system. The oxygen somehow goes from your lungs to you heart and then the oxygen goes into your blood and is then carried through out your body. Thats pretty much all I know, it’s been a while since I learned about that stuff. Sorry I couldn’t be more help.
