the organ in the excretory system which filters waste products from blood plasma and controls water balance

a combination of urea, and excess water and ions which is stored in the bladder until urinated

Controlling water balance: the kidneys, nephron structure and kidney failure

Biology

Pupils will learn about factors that affect the rate of photosynthesis in plants, including temperature, light intensity and carbon dioxide concentration.

Pupils learned how substances essential for chemical reactions, and the products of the reactions, are transported into, around and out of plants, and about factors affecting the rate of water uptake by a plant.

Coordination and control: maintaining a constant internal environment

Which substances are reabsorbed by the kidney tubules?

Match each part of the kidney tubule (nephron) to its correct name.

If you drink too much water, which of these will happen?

causes the concentration of urea and ions in the blood to increase

the blood is filtered by an external machine

a damaged kidney is removed and replaced with a donated kidney

contains dissolved substances such as glucose and ions

Match the constituent of blood to its description.

Label these parts of the excretory system.

The process that uses glucose as a fuel to transfer energy for life processes is called cellular {{}}.
