Question

Is the spleen superior to the kidney?

Answer 1

The excretory system is a passive biological system that removes excess, unnecessary materials from an organism's body fluids in order to maintain internal chemical homeostasis and protect the body from damage. Excretory systems have two functions: they eliminate metabolic waste products and they drain the body of used up and broken down components in a liquid and gaseous state.

Complete answer:
The spleen is a vertebrate organ that can be found in all vertebrates. It looks like a large lymph node and serves primarily as a blood filter. The spleen is involved in the production of red blood cells (erythrocytes) as well as the immune system. It recycles iron and removes old red blood cells, storing a reserve of blood that can be useful in the event of hemorrhagic shock.

It metabolizes haemoglobin removed from senescent red blood cells as part of the mononuclear phagocyte system (erythrocytes). The globin portion of haemoglobin is broken down into its constituent amino acids, while the heme portion is converted to bilirubin, which is excreted by the liver.

The spleen's anterior end, which resembles a border, is expanded and directed forward and downward to reach the midaxillary line. It rests on the upper pole of the left kidney and has a rounded posterior end that is directed upward and backwards. The superior, inferior, and intermediate borders of the spleen.

Thus, yes, the spleen is superior to the kidney.

Note: Splenomegaly is the enlargement of the spleen. Sickle cell anaemia, sarcoidosis, malaria, bacterial endocarditis, leukaemia, pernicious anaemia, Gaucher's disease, leishmaniasis, Hodgkin's disease, Banti's disease, hereditary spherocytosis, cysts, glandular fever (mononucleosis or 'Mono' caused by the Epstein–Barr virus), and tumours are some of the conditions that can cause Hemangiomas and hemangiosarcomas are primary tumours of the spleen. Splenomegaly can cause the spleen to take up a lot of space on the left side of the abdomen.
