Study Notes
Excretion and Temperature Regulation
- The skin plays a major role in controlling body temperature.
- The lungs excrete both carbon dioxide and water.
- The kidneys are the main organs of excretion and homeostasis in the human body.
- The outer layer of the kidney is called the cortex.
- The thin tube that connects the pelvis of the kidney to the bladder is called the ureter.
- Filtered and purified blood leaves the kidney through the renal vein.
- The production of weak, watery pale urine to increase the concentrations of bodily fluids is called diuresis.
- The production of dark-colored, strong, concentrated urine is caused by dehydration.
- The adrenal glands are located on top of the kidneys.
- There are four organs of excretion in the human body: kidneys, skin, liver, and lungs.
- The nephrons in the kidney do not produce hormones.
- Anti-diuretic hormone (ADH) regulates the amount of water reabsorbed by the kidneys into the bloodstream.
- Ectotherms, such as reptiles, obtain the heat they require from the environment.
Sweat and Temperature Regulation
- Sweat plays a crucial role in temperature regulation by evaporating and cooling the body.
- The hypothalamus acts as the thermostat of the body, regulating temperature control.
- Shivering is not a cooling mechanism of the body.
- During temperature regulation, blood vessels near the skin's surface dilate to release heat.
- The erector muscle is not involved in temperature regulation.
- The loop of Henle is involved in the reabsorption of ions and water in urine production.
- When the blood becomes more dilute due to drinking a lot of water, the kidneys produce more dilute urine.
