Study Notes
Urinary System
- Main function: Disposes of waste and excess materials, regulates internal conditions (body temperature, water content, blood content) in collaboration with cardiovascular and respiratory systems.
- Homeostasis: Maintains internal environment relatively constant.
- pH: Power of Hydrogen, level of acidity, blood pH ~7.0-7.5.
- Temperature ~ 30°C.
- Organs:
- Kidney: Main filtering organ.
- Ureter: Delivers urine from kidneys to bladder.
- Bladder: Stores urine until release.
- Urethra: Disposes urine from body.
- Skin: Part of the system.
Urinary System - Health
- Urine contains waste materials, excess water, and urea.
- Body reabsorbs proteins and sugars (carbohydrates).
- Excess ions are also components of urine.
Urinary System - Organs Detail
- Nephrons (filtering tissues):
- Glomerulus: Filtration structure.
- Tubule: Connector.
- Henle Loop: Reabsorption of usable materials.
Homeotherm
- Maintains constant body temperature despite environmental changes, also known as warm-blooded or endothermic.
Cold-blooded Organisms
- Body temperature changes with the environment, also known as ectothermic.
Skin Functions
- Forms a tough outer layer resisting damage.
- Acts as a barrier against pathogens.
- Prevents water loss from the body.
- Acts as a sensor for touch and temperature.
- Regulates heat loss.
Skin Color
- Color variations based on melanin amounts.
- Fair Skin: Low melanin content, low UV resistance.
- Medium Skin: Moderate melanin content, medium UV resistance.
- Dark Skin: High melanin content, high UV resistance and protection.
Skin Health
- Radiation (UV): Exposure to too much UV light can cause burns, skin cancer; sunscreen use is important.
- Albinism: Lack of melanin.
- Sanitary: Dirt and particles can block pores, causing acne, microorganisms infections.
Other Body Systems Notes
-
Sense Organs
- Eyes: Components, function.
- Skin: Sensory receptors for touch, pressure, pain, temperature, and texture.
- Ear: Hearing and balance, components.
- Nose and Tongue: Sense of smell and taste.
-
Skeletal System
- Functions: Gives shape and structure to the body, point of attachment for muscles.
- Composition of bone: 70% inorganic materials (calcium & phosphorus).
-
Muscular System
- Main function: Allows movement.
- Creates heat in body, important for temperature regulation.
- Different types of muscles (skeletal, smooth, cardiac) have different placements and functions.
-
Skeletal, Muscular & Nervous system - table data summarizes details about these systems.
