Question

Homeostasis is the defined as the maintenance of an internal environment. A subset of this is Thermoregulation , which is the maintenance of body temperature. A reptile is an example of an Ectotherm , which means that its body temperature fluctuates with the external environment.

Answer 1

When body temperature increases, blood flow increase to the surface of our skin and we begin to dilate. When there is excess salt of water, blood is filtered by the kidneys so urine can be formed by the functional unit of the kidney known as nephrons. Urine leaves the nephrons and travels through the collecting duct to ureters. Ureters then send urine to the urinary bladder for storage until it is expelled from the body through the urethra.

Human excretory system helps in the removal of excess salt from the body. This is caarried out in the organs known as kidneys. The functional unit of kidney is nephron. Nephrons are small filters which removes excess salt and collect it in collecting duct from where it is transported to the ureters. Ureters carry urine to urinary bladder and then it is expelled through urethra. The process of expulsion of urine from body is known as micturition
