Solution
Excretory system is a biological process that removes unnecessary, excess materials from the body fluids of an organism, which helps to maintain internal homeostasis and to prevent damage to the body. Organs of excretion build up the excretory system which consists of the Kidneys, ureter, urinary bladder, and urethra.
Complete answer:
Henle’s Loop (Loop of Henle): It is a long U-shaped portion of the tubule which is located in the medulla of the kidney that conducts urine within each nephron of the kidney. The main function of Henle's loop is to reabsorb water and sodium chloride from urine.
Ureter: Each ureter is a small tube they are about 8 to 10 cm long. Urine travels from the kidneys to the urinary bladder, about every 10 to 15 seconds a small amount of urine flows from the ureter to the bladder.
Urinary bladder: Urinary bladder or bladder is a muscular organ that is the most elastic organ of the body and situated in the lower abdomen which sits on the pelvic floor. The primary function of the urinary bladder serves as a temporary storage area for urine which delays the frequency of urination.
Malpighian corpuscle: Malpighian corpuscles also known as kidney corpuscles and these structures are involved in the filtration of the process of ultrafiltration during the waste removal from the body and filter out the blood.
Proximal convoluted: Proximal convoluted is the convoluted portion of the nephron which lies in between the bowman’s capsules and loop of Henle’s. The primary function involves the reabsorption of sugars, sodium ions, and water from the glomerular filtrate.
Hence, the correct answer is option (D).
Note: Excretory system plays a vital role in getting rid of excess metabolic waste; eliminates toxic byproducts excreted from cells, and helps in the maintenance of balanced chemical concentration in the body.
