Study Notes
Respiratory System
- Function: Provides oxygen to the body and removes carbon dioxide.
- Main Organs:
- Lungs: Main organ where gas exchange occurs.
- Trachea: Air passageway to the lungs.
- Bronchi and Bronchioles: Tubes that direct air into the lungs.
- Alveoli: Tiny air sacs where oxygen enters blood and carbon dioxide exits. Alveoli have adaptations like thin walls which allow easy gas exchange, a rich blood supply to assist in the transfer of gases, and a large surface area to maximize gas exchange.
- Diaphragm: Muscle that helps in breathing.
- Process:
- Oxygen is inhaled into the lungs.
- Oxygen diffuses into the blood at the alveoli.
- Carbon dioxide is removed from the blood and exhaled.
- During Exercise:
- Breathing rate increases to supply more oxygen.
- More carbon dioxide is removed.
- Deep breathing improves oxygen intake.
Digestive System
- Function: Breaks down food into nutrients the body can use.
- Main Organs:
- Mouth: Breaks down food using teeth and saliva.
- Esophagus: Moves food to the stomach.
- Stomach: Uses acid and enzymes to digest food
- Small Intestine: Absorbs nutrients into the blood. Villi are adaptations with thin walls, a large surface area, and blood capillaries to maximize nutrient absorption
- Large Intestine: Absorbs water and forms waste.
- Liver and Pancreas: Help in digesting fats and regulating blood sugar
Circulatory System
- Function: Transports oxygen, nutrients, and waste around the body.
- Main Organs:
- Heart: Pumps blood around the body.
- Blood Vessels:
- Arteries: Thick walls, carry oxygenated blood away from the heart.
- Veins: Thin walls, carry deoxygenated blood back to the heart.
- Capillaries: Tiny vessels for gas exchange.
- Blood Components:
- Red Blood Cells: Carry oxygen.
- White Blood Cells: Fight infection.
- Platelets: Help with blood clotting.
- Plasma: Carries nutrients and waste.
- During Exercise:
- Heart rate increases to pump more oxygen to muscles.
- More carbon dioxide removed through the lungs.
Endocrine System
- Function: Produces hormones to regulate body functions.
- Main Glands & Hormones:
- Pancreas: Produces insulin to control blood sugar.
- Adrenal Glands: Produce adrenaline for the "fight or flight" response (e.g., excited, scared).
- Thyroid: Produces thyroxin, regulates metabolism.
- Pituitary Gland: Controls other glands and produces growth hormone.
- Reproductive glands:
- Ovaries: Produces estrogen and progesterone in females.
- Testes: Produces testosterone in males.
Nervous System
- Function: Controls body movements and responses.
- Main Parts:
- Brain: Processes information and controls actions.
- Spinal Cord: Sends signals between the brain and body.
- Nerves: Carry messages to and from the brain.
- Neurons: Nerve cells made of cell body, dendrites, axon, and myelin sheath; dendrites receive impulses, axons transmit.
Reflex Arc
- A response to a stimulus
- Stimulus -> Receptor -> Sensory neuron -> Spinal cord -> Motor neuron -> Effector -> Response.
