Study Notes
Human Respiratory System
- The respiratory system is responsible for gas exchange, taking in oxygen and releasing carbon dioxide.
- Key structures include the nose, pharynx, larynx, trachea, bronchi, and lungs.
- The lungs contain millions of alveoli, tiny air sacs where gas exchange occurs.
- Inhalation involves the diaphragm contracting and expanding the chest cavity, drawing air into the lungs.
- Exhalation involves the diaphragm relaxing, reducing the chest cavity volume and pushing air out.
- The respiratory system is vital for maintaining homeostasis by regulating blood pH through carbon dioxide levels.
- Various factors can affect lung function, including smoking, air pollution, and respiratory illnesses.
- Respiratory disorders like asthma, chronic bronchitis, and emphysema impact air flow and gas exchange.
- The process of breathing is controlled by the respiratory center in the brainstem, which adjusts the rate and depth of breathing based on blood gases.
- The respiratory system protects against pathogens through mucus and cilia in the airways.
- Gas exchange is driven by pressure differences; high pressure in inhaled air drives air into the lungs, and the lower pressure in the lungs allows gas exchange across the alveoli.
Human Excretory System
- The excretory system removes waste products from the body.
- Key organs are the kidneys, ureters, bladder, and urethra.
- The kidneys filter blood, removing waste products like urea and excess water.
- Filtering blood in kidneys involves glomerular filtration, tubular reabsorption, and tubular secretion.
- Filtered waste is expelled from the body as urine via the ureters to the bladder, and then through the urethra.
- The excretory system regulates water balance, electrolyte levels, and blood pressure within the body.
- Kidney function helps maintain acid-base balance in the body, contributing to overall homeostasis.
- The excretory system is integral to homeostasis as it balances water and electrolyte, controls blood pressure, eliminates waste, and maintains pH.
- Failure or damage to the kidneys can lead to serious health problems, and necessitates treatments like dialysis.
- The bladder stores urine until excretion.
- The urethra carries urine out of the body.
Human Reproductive System
- The reproductive system is responsible for the creation of offspring.
- The male reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis.
- The testes produce sperm, and the accessory glands produce seminal fluid.
- The female reproductive system includes the ovaries, fallopian tubes, uterus, and vagina.
- Ovaries produce eggs (ova), and the fallopian tubes transport eggs to the uterus.
- Fertilization occurs in the fallopian tubes.
- Implantation occurs when the fertilized egg attaches to the uterine wall.
- During pregnancy, the fetus develops inside the uterus, supported by the placenta.
- Hormones play a critical role in regulating reproductive function, controlling the menstrual cycle and influencing sexual characteristics.
- The male and female reproductive systems differ significantly in their structures and functions.
- External genitalia vary greatly between sexes, including anatomical differences for sperm and egg maturation and transport.
- Common reproductive health concerns include sexually transmitted infections, infertility, and various cancers.
- Menstruation is a periodic discharge of blood and uterine tissue occurring in females of reproductive age.
