Study Notes
Nervous System
- Cerebrum: Largest part of the brain, responsible for higher brain functions such as thought, action, and emotion.
- Cerebellum: Coordinates movement, balance, and posture; essential for motor control and learning new physical skills.
Endocrine System
- Adrenal Gland: Produces hormones like adrenaline that regulate metabolism, immune response, and stress reactions.
- Thyroid: Regulates metabolism through hormones such as thyroxine; influences growth and energy levels.
- Ovaries: Produce estrogen and progesterone, crucial for female reproductive health and regulation of the menstrual cycle.
- Testes: Responsible for producing testosterone, vital for male sexual development and sperm production.
Cardiovascular System
- Heart: Muscular organ that pumps blood throughout the body; ensures the delivery of oxygen and nutrients to tissues and removal of waste products.
Respiratory System
- Lungs: Main organs of respiration; facilitate gas exchange—oxygen intake and carbon dioxide expulsion.
- Trachea: Air passageway connecting the throat (pharynx) to the lungs; contains cartilage rings for structure.
Digestive System
- Stomach: Breaks down food using acid and enzymes; churns food into a semi-liquid form known as chyme.
- Liver: Produces bile to help digest fats; also processes nutrients and detoxifies harmful substances.
- Pancreas: Produces digestive enzymes and hormones like insulin, which regulates blood sugar levels.
- Small Intestine: Site of most digestion and nutrient absorption; consists of three segments: duodenum, jejunum, ileum.
- Large Intestine: Absorbs water and salts from indigestible food matter; compacts waste into feces for excretion.
Lymphatic System
- Spleen: Filters blood, recycles iron, and plays a role in immune system responses by storing white blood cells.
Urinary System
- Kidneys: Filter blood to produce urine, regulate fluid and electrolyte balance, and remove waste products.
- Urinary Bladder: Stores urine until it is excreted from the body; controls urination process.
