Human Circulatory System
Small organisms dont have a bloodstream, but instead rely on the simple diffusion of materials
for transport around their cells. This is OK for single cells, but it would take days for molecules
to diffuse through a large animal,
The kidneys remove urea and other toxic wastes from the blood, forming a dilute
solution called urine in the process. The two kidneys have a very extensive blood supply
and the whole blood supply passes through the kidneys every 5 minutes, ensu
Just over half of the blood volume is made up of a pale yellow fluid called plasma.
The rest of the blood is made up of cells (red blood cells and white blood cells) and
Blood has several vital functions:

Homeostasis literally means same state and it refers to the process of keeping the
internal body environment in a steady state. The importance of this cannot be overstressed, and a great deal of the hormone system and autonomic nervous system
Ecology is the study of inter-relationships between organisms and their environment. Its
aim it to explain why organisms live where they do. To do this ecologists
study ecosystems, areas that can vary in size from a pond to the whole planet.
Energy and Matter
Before studying ecosystems in any further detail, it is important to appreciate the
difference between energy and matter. Energy and matter are quite different things and
cannot be inter-converted.
Energy comes in many different forms (s
Metabolism refers to all the chemical reactions taking place in a cell. There are thousands of these in a
typical cell, and to make them easier to understand, biochemists arrange them into metabolic pathways.
