Semester 1, Day 11
Digestive and Urinary Systems
Agenda Review for Circulatory and Respiratory Quiz Turn in Homework Take Quiz Lecture on Digestive and Urinary Systems Work/Reading Time
Review for Quiz Relationship between circulatory and
respiratory systems Label the heart diagram Draw movement of blood on a heart
diagram Definitions for circulatory system:
Artery, Atrium, Blood, Blood Vessels, Capillaries, Heart, Plasma, Platelets, Red Blood Cells, Valve, Vein, Ventricle,White Blood Cells
Which side of the heart is oxygenated? How can you tell from the movement of blood?
Definitions for respiratory system: Alveoli, Bronchus, Diaphragm,
Epiglottis, Larynx, Lungs, Nasal Cavity, Trachea
Label a diagram of the respiratory system
Understand how the diaphragm functions
Septum
Homework Turn In Sections 37.1 and 37.2 Questions:
37.1 #1, 2, 4, 5 37.2 #1-5
Quiz on Circulatory and Respiratory System Correction on Question 4 Take quiz silently Eyes on your own paper When finished, flip over
Digestive & Urinary
Digestive System: breaks
down food mechanically
and chemically for
nutrients. Solid Waste
Urinary System: cleans,
balances chemicals &
regulates water for
blood. Liquid Waste.
Digestive System
The Mouth
Teeth: crush food
(mechanical)
Salivary Glands:
Secrete saliva
Digestive enzyme
called amylase breaks
down sugars (chemical)
Tongue: Pushes food
Digestive System
Epiglottis: prevents
food from entering
resp. system
Pharynx: between
mouth & esophagus
(throat)
Esophagus: muscular
tube stomach
Digestive System
Stomach:
Muscles that
mechanically break
down food
Acidic gastric juice
breaks food down
chemically
Digestive System
Stomach Small Intestine
Small Intestine: 20 ft long,
narrow muscular tube.
Nutrients from food
blood.
Liver: bile for SI that breaks
down fats
Gallbladder: stores bile until
it enters the SI
Pancreas: produces insulin
for SI, which regulates blood
sugar
Digestive System
Small Intestine Large
Intestine (Colon)
Large Intestine
Colon: absorbs water from
indigestible food
Rectum: storage site for
feces
Anus: exit for feces
Appendix: a vestigial
structure human no longer
need
Break
Urinary System Kidneys: filter blood to remove
waste (urine)
Aorta: blood from heart kidney
Inferior Vena Cava: blood from
kidney heart
Renal Artery: blood from aorta
kidney
Renal Vein: blood from kidney IVC
Ureter: urine from kidney bladder
Urinary Bladder: holds urine
Urethra: moves urine out of body
Urinary System Kidney
Renal Artery: unclean blood to
kidney
Renal Vein: clean blood away
from kidney
Renal Medulla: regulates water
& salt in blood
Renal Cortex: filters blood
Renal Pelvis: collects urine as
blood is cleaned
Ureter: carries urine to bladder
Homeostasis How are these four systems connected? Cellular Respiration:
C6H12O6 + O2 CO2 + H2O + ATP Glucose + oxygen carbon dioxide + water + energy
1. Digestion breaks down glucose enters blood to go to cells
2. Oxygen obtained by lungs enters blood to go to cells3. Cells use glucose & O2 to create ATP, CO2 and H2O
4. Carbon dioxide picked up by blood released from lungs5. Water & waste removed from blood by urinary system
Homeostasis: all organ systems work to keep body conditions balanced (water, energy, waste, temperature)
