1. Quick review of the system
1. Quick review of the systems
• A) cellular respiration– We are able to survive because of cellular
respiration (explained by the following formula)
C6H12O6 + O2 CO2 + H2O + energy
1. Quick review of the systems
C6H12O6 O2 CO2 H2O
1. Quick review of the systems
Lungs (O2) + Digestion (Nutrients)
• Cells (location of cellular respiration)
C6H12O6 + O2 CO2 + H2O + water
Lungs (CO2) + Sweat glands and kidneys (H2O)
2. Sweat Glands
Not only for eliminating excess water
2. Sweat Glands
A) Function: - Regulates the internal body temperature- Sweat can be produced as a result of stress,
heat or exercise
B) Anatomy:- Sweat glands are located in the dermis of the
skin (inner most layer)
- Long coiled tube that connects to pores on the skins surface
2. Sweat Glands
C) Types:1. Eccrine sweat glands:
- Located all over, especially hands, feet and forehead
2. Apocrine sweat glands :- Usually ends with a hair
- Larger and sweat produced contains fatty acids and proteins
- When bacteria on the persons hair and skin metabolizes the fatty acids an odor is produced
2. Sweat Glands
• Fun Facts:– We have about 2.6 million sweat glands
– Dogs and cats do not sweat: They pant to regulate their temperature
3. Urinary System
3. Urinary System
A) Function- Produces and expulses urine and other waste products
from the body- Ensures that the volume of the blood and its concentration
remain constant
B) Anatomy1. Kidneys
2. Ureters
3. Bladder
4. Urethra
3. Urinary System1. Kidneys
i) Function:• Regulates the water content in the blood• Filter about 1500 L of blood a day
ii) Appearance:• Looks like a bean• Left kidney higher by 2.5 cm
iii) Each Kidney has three parts• Pelvis• Medulla Nephrons filter the blood• Cortex

iv) Nephrons:– Working unit of the kidneys
3. Urinary System
2. Ureter- 25 cm long tubes that brings the urine from the
kidneys to the bladder
3. Bladder- Expandable reservoir (1L)
4. Urethra- 3-4 cm long for women: 20 cm long for men- Brings urine out of the body
3. Urinary System
C) Physiology:
3. Urinary System
D) Urine Composition– Urine is a homogeneous mixture:
• 95% of water• 2.5% urea (made from the oxidation of amino
acids)• Minerals• Excess substances
– Drugs and medications– Proteins, glucose, lipids, blood cells (presence of these
components indicates a health problem)
3. Urinary System
E) Concentration
– Definition:• Concentration is the quantity of dissolved solute in a
given amount of solution• Concentrations can be measured in g/L, %
– C=m/V where …C equals the concentration in g/Lm is the mass of solute (g)V is the volume of the solution
(L)
3. Urinary System
F) Dilution– Definition:
• Dilution is the process of decreasing the concentration of a solution by adding solvant (liquid)
– C1V1 = C2V2
• Where C1 is the concentration of the initial solution
V1 is the volume of the initial solution
C2 is the concentration of the final solution
V2 is the volume of the final solution
3. Urinary System
F) Diagnosing Disease– Doctors used to taste urine to diagnose diabetes (it
would be sweeter)
– What about the color?• Green/blue Food coloring• Purple Blackberries• Brown Black water Fever• Orange Carrots• Clear Drank a lot of liquids• Dark Yellow Sweated alot
