Study Notes
Transportation in Animals and Plants
- The circulatory system transports useful and harmful materials throughout the body
- The excretory system removes harmful materials from the body
- Plants also transport substances
- Substances like oxygen, nutrients and waste products are transported
- The circulatory system has blood, blood vessels and a heart
- Blood transports digested food, oxygen and waste
- Blood consists of plasma, red blood cells, white blood cells and platelets
- Plasma is the liquid part carrying nutrients and wastes
- Red blood cells carry oxygen
- White blood cells fight disease
- Platelets help clot blood
- Arteries carry oxygenated blood away from the heart
- Veins carry deoxygenated blood to the heart
- Capillaries are tiny blood vessels for exchange
- The heart pumps blood throughout the body
- The right side pumps deoxygenated blood to the lungs
- The left side pumps oxygenated blood to the body
- The heart has four chambers: two atria and two ventricles
- Valves control blood flow direction
Transportation in Plants
- Plants need to transport carbon dioxide and water for photosynthesis
- Food produced is then transported to other parts of the plant
- The transport system in plants is made of tissues
- Xylem and phloem are vascular tissues
- Root hairs absorb water and minerals from the soil
- Water and minerals move from cell to cell in the root then through the xylem vessels
- Water and nutrients move upwards in the stem and branches
- Carbon dioxide enters the leaves through stomata
- The food is transported to other parts of the plant via phloem
- Movement of food is called translocation
- Factors that affect transpiration rate include: temperature, humidity and wind speed
Waste Excretion
- Removal of waste is important for the body
- The excretory system removes waste
- The excretory system is made up of two kidneys, a pair of ureters, the urinary bladder, and the urethra
- The kidneys filter blood to remove urea
- Ureters connect each kidney to the bladder and move urine
- The bladder stores urine
- The urethra excretes the waste from the body
- Waste products like urea are toxic if they accumulate
- Processes involved are filtration, absorption, diffusion, and excretion
- Kidneys contain nephrons, which are small filtering units
- Blood under pressure allows filtration of water, glucose, vitamins and salt
