Give a brief outline of the process of excretion, by the kidneys, in human beings.
Answers
There are two processe involved ' n this
Ultrafiltration of blood which is the process that involves the filtration of blood under hydrostatic pressure caused by the blood vessel entering the kidney ( afferent areteriol) being larger than the one exiting the kidney
This causes the filtrate to be collected in the bow Man's capsule as glomerular filtrate
This contains some useful materials needs by the body so these are selectively reabsorbed and the rest is urine so it is. Taken to the ureter then to to urinary bladder to be deposited by through the urethra by the timely contraction and relaxation of the sphincter muscles to the surrounding (toilet)
Explanation:
Answer. Humans have two kidneys and each kidney is supplied with blood from the renal artery. Thekidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in thekidney.
