Human Organs
- Skin: Protects and senses
- Lungs: Takes in oxygen, removes carbon dioxide
- Liver: Processes substances
- Small Intestine: Digests food, absorbs into blood
- Bladder: Stores urine
- Blood Vessels: Carry blood
- Heart: Pumps blood
- Diaphragm: Aids breathing
- Stomach: Aids digestion
- Kidneys: Filter blood, produce urine
- Large Intestine: Removes water from undigested food
Blood Composition
- Plasma (55%): Water, ions, proteins, nutrients, wastes, gases
- Red Blood Cells (41%): Carry oxygen
- White Blood Cells & Platelets (4%): Important for immunity and blood clotting
Red Blood Cells
- Shaped like biconcave discs
- No nucleus
- Filled with hemoglobin, which carries oxygen
- Made in bone marrow
- Transport oxygen
White Blood Cells
- Phagocytes: Capture and destroy microorganisms
- Lymphocytes: Produce antibodies to fight infection
Blood Transport in Mammals
- Blood transports oxygen and nutrients to cells.
- It also removes carbon dioxide and other waste products.
Microscopy
- Microscopes enable viewing blood components
- Parts of a microscope include eyepiece lens, objective lens, slide, stage, and mirror.
