What does blood do?
- Blood is a transporter. It transports nutrients, oxygen, carbon dioxide, hormones, etc. to and from cells and organs.
- It removes waste from tissue that is then sent to organs for excretion.
- When necessary, blood clots which helps to retain body fluids.
- It regulates blood pressure and body temperature.
- Antibodies destroy pathogenic substances and white blood cells attack invading organisms.
- Inflammatory Phase. After injury, bleeding, swelling and redness may occur. This is a vascular response whereby blood flow is increased to the injured area, transporting nutrients to assist in the healing.
- Repair Phase. Collagen fibers begin to repair damaged tissue, most likely in the form of scar tissue. At this stage, the injury begins to feel 'better'. There is an increased risk for re-injury as the tissue is not strong enough to handle intense activity.
- Remodel Phase. Soft tissue strength, quality and elasticity begin to improve, hopefully back to normal.
