In order to remember the definition of homeostasis it is useful to memorise the mnemonic ‘MACIE’; the Maintenance of A Constant Internal Environment. Conditions in the body must be constantly controlled because cells depend on the body’s environment to live and function. The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly.

Conditions that must be controlled include temperature, blood sugar level and water content and they are all controlled by different hormonal and nervous systems.

For example, the maintenance of body temperature is controlled by the brain. The body’s temperature must be kept at 37 degrees because this is the temperature at which enzymes optimally function.

Temperature receptors in the skin detect changes in the external environment and pass this information on to the brain’s processing centre, the hypothalamus. The hypothalamus itself also has receptors that detect changes in the blood temperature. If the external/internal temperature changes, the hypothalamus will automatically trigger changes in the body’s effectors (sweat glands and muscles) to keep our temperature constant.

If we are too hot; glands in the skin secrete sweat onto the surface to increase heat loss by evaporation.

If we are too cold; arrector pilli muscles in the skin contract and cause the hair on our arms to stand up straight, trapping a layer of warm air next to the skin to reduce heat loss. It is the contraction of these muscles that causes the appearance of goosebumps when we’re cold.”

Waste is transported from the kidneys in the form of urine.

T or F

Answers

This is true. Waste is transported from the kidneys in the form of urine.

The cellular metabolism generates many by-products which are rich in nitrogen and must be cleared from the bloodstream, as they can be harmful for the human body such as urea, uric acid, and creatinine.

These by-products are expelled from the body during urination, which is the primary method for excreting water-soluble chemicals from the body or all the waste out of the body.

Waste products are removed in the form of urine by the kidney.

Further Explanation:

The kidneys are the major excretory organs of the body. It is a bean-shaped and fist-sized organ that lies in the lower back of the body. It is located behind the peritoneum on the posterior side of the abdominal wall. The system contains two kidneys, extended from last thoracic to a third lumbar vertebra or near the vertebral column. The right kidney is slightly lower than the left, but they are of the same size. It measures about 3cm thick, 11cm long and 5cm wide. Urine is a waste byproduct that contains excess water and waste material formed during metabolic activity. The process involves three steps; filtration, secretion, and reabsorption:

• Filtration: The afferent arteriole supplies the blood into the glomerulus. The blood will then move inside the glomerulus. The glomerulus capillaries filter the blood based on their particle size. It will extract the non-filterable substances such as albumin and cell from blood and transfer the nitrogenous waste and water into the Bowman’s capsule.

• Reabsorption: In this step, the ions and molecules are reabsorbed by the capillaries surrounding the tubules. The glomerular filtrate passes through the tubule part of the nephron.

• Secretion: This step involves the movement of some substances (metabolic byproduct) with toxic properties and drugs that are not normally formed within the body.
