Which organ in the lymphatic system does the breakdown of damaged red blood cells take place?

Spleen

The spleen is the organ in the lymphatic system which does the breakdwon of damaged red blood cells. It works as a blood filter and it can be found in the abdominal area.

It has two types of tissues: the red pulp tissue and the white pulp tissue. The red pulp tissue is the one who checks the levels of red blood cells storaged in our body and gets rid of the bad, preventing any risk of getting an infection.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
