Multiple Choice

Why is excretion important for achieving osmotic balance in the body?

Excretion prevents the absorption of nutrients, maintaining energy levels.

Excretion removes excess salts and wastes, helping to maintain fluid balance.

Excretion directly regulates the body's temperature by releasing heat.

Excretion increases the production of red blood cells, enhancing oxygen transport.

Verified step by step guidance

Understand the concept of osmotic balance: Osmotic balance refers to the regulation of water and solute concentrations in the body to maintain homeostasis. It is crucial for the proper functioning of cells and organs.

Identify the role of excretion in osmotic balance: Excretion is the process by which the body removes waste products and excess substances, including salts and water, to maintain osmotic balance.

Recognize the importance of removing excess salts: Excess salts can disrupt osmotic balance by altering the concentration of solutes in body fluids, which can affect cellular function and fluid distribution.

Consider the removal of waste products: Waste products, such as urea and creatinine, need to be excreted to prevent their accumulation, which can affect osmotic balance and overall health.

Connect excretion to fluid balance: By removing excess salts and waste, excretion helps regulate the volume and composition of body fluids, contributing to osmotic balance and homeostasis.
