Question: Explain how exchange nutrients and waste products between food and tissue cells?

Nutrient and waste exchange between food and tissue cells happens through the bloodstream. Here's how it works:

Digestive System: Food is broken down in the digestive system into smaller molecules like glucose, amino acids, and fatty acids.

Absorption: These nutrients are absorbed into the bloodstream from the intestines.

Transport: The circulatory system transports these nutrients to cells throughout the body.

Cellular Uptake: Cells take up these nutrients from the blood through their cell membranes, using them for energy, growth, and repair.

Waste Production: As cells use nutrients, they produce waste products like carbon dioxide and urea.

Removal: These waste products are transferred back into the bloodstream.

Excretion: The waste is transported to the excretory organs (like the kidneys and lungs) and removed from the body through urine, sweat, or exhaled air.
