Third order
Continents & ocean are first order. Mountain,pleated & plains are second order of relief features.
the pulmonary artery
Well um.... there are a few more than just one I'll list them all.... coronary Arteries; the brachiocephalic artery; left common carotid artery; left subclavian artery; oesophageal artery; right and left bronchial artery; mediastinal artery; poterior intercostal arteries; subcostal arteries; inferior phrenic artery, celiac trunk artery, middle suprarenal artery; superior mesenteric artery; renal artery; 1st through 4th lumbar arteries; and finally the artery bifurcates.
The right ventricle pumps blood into the pulmonary artery.
Selective catheter placement
Vena cava --> Right atrium --> Tricuspid valve--> Right ventricle --> Pulmonary artery --> Pulmonary semilunar valve --> Lungs --> Pulmonary vein --> Left atrium --> Mitral valve --> Left ventricle --> Aortic semilunar valve --> Aorta --> Carotid artery, Brachial artery, femoral artery, etc... --> Arterioles --> Capillaries --> Venules --> Veins --> Vena cava
Second-order consumers feed on first-order consumers. An eagle is an example of a second-order consumer. Examples of first-order consumers are rabbits and mice.
Producer- first order consumer- second order consumer- third order consumer etc
Linear system of arbitrary complexty can be viewed as being composed of first and second order
Continents & ocean are first order. Mountain,pleated & plains are second order of relief features.
Here is the order it goes from right thumb to left thumb. 1. radial vein 2. brachial vein 3. axillary vein 4. left subclavian vein 5. brachiocephalic vein 6. superior vena cava 7. right atrium 8. right ventricle 9. pulmonary trunk 10. pulmonary arteries 11. lobar arteries 12. pulmonary capillaries 13. pulmonary venules 14. pulmonary veins 15. left atrium 16. left ventricle 17. aorta 18. brachiocephalic artery 19. right subclavian artery 20. axillary artery 21. brachial artery 22. radial artery

in second order filter attenuation to the frequencies in stop band is higher then first order filters.
The first thing is to determine what artery provides blood to the lower right first molar. The lower teeth sit in the mandible and are supplied by branches of the The major artery in the mandible supplying the teeth is the inferior alveolar artery, which sends branches to supply the roots of each tooth (including the first molar) in the lower jaw. Next is to find the origin of the inferior alveolar artery and work backwards until we get to the ascending aorta. The inferior alveolar artery is a branch of the internal maxillary artery, which itself is a branch of the external carotid artery. The external carotid artery is a branch of the common carotid artery. So far everything has been symmetrical, so it hasn't mattered whether we specified that the artery was on the right or the left side. But the common carotid arteries behave a little differently. The right common carotid is a branch of the innominate artery, which branches from the aortic arch. The left common carotid artery branches directly from the aortic arch. Since we're concerned with the lower right first molar, we'll work backwards from the right common carotid, innominate artery, and aortic arch. The last bit is just to know that the aortic arch is an extension of the ascending aorta. With that, we're done. Now we just sew the whole thing together, artery by artery, in the reverse order: Ascending aorta -> aortic arch -> innominate artery -> right common carotid artery -> right external carotid artery -> right internal maxillary artery -> right inferior alveolar artery -> branch to lower right first molar.
Second order questions are questions about other questions. First order questions can stand by themselves. "Do you like blue?"-first order. "what kind of blue"-second order. Hopefully someone can verify that. More examples: "How to go to library?" - 1st order "Is there a better way to go to library?" - 2nd order
