The filters inside a kidney are called nephrons. Each kidney contains thousands of nephrons, which are responsible for filtering waste and excess substances from the blood to form urine.
Ultra-filtration within the kidney forces the waste product out, during the process some smaller useful material are also forced out into urine. These are then reabsorbed, this is called selective re-absorption.
The smooth membrane tightly adherent to the kidney's surface is called the renal capsule. It is a fibrous covering that protects the kidney and helps maintain its shape and position within the body.
Porifera are sponges, and many animals eat sponges, including nudibranchs and some specialized fish.
glomerulus is the clusture of cappillaries it is present along with cupshaped capsule called bowman's capsule or it is collectively called renal corpuscle
The cavity within the kidney that collects urine is called the renal pelvis. From the renal pelvis, urine travels down the ureter to the bladder for storage and eventual excretion.
Robert Hooke in 1665 found microscopic spots contained within a slice of cork. He called these spots cells.
Tubules are the tubes running through each little (microscopic) nephrons within each kidney that aid in filtering and collecting of the waste products, and then depending on how much water is in the body it either can reabsorb more water or more salt depending on your electrolyte balance. :-D

No, nephroptosis is not suppuration within the kidney. Nephroptosis, also known as a floating kidney, occurs when the kidney drops down into the abdomen due to inadequate support from surrounding structures. Suppuration refers to the formation of pus within tissues, which is usually a result of bacterial infection.
Cells within the kidney called interstitial fibroblasts produce a substance called erythropoietin, EPO for short, that stimulates production of red blood cells. They doesn't secrete or produce red blood cells themselves. Red blood cells are produced within bone marrow.
