Do Now: Biology Review
1. Which human body system unit did you find the most difficult this year?
2. Which one did you find the least difficult?
HW: Study for 20 min. each night to prepare
for the final exam.
Units we studied: Digestion, Circulation, Excretion, Respiration, Nervous, Endocrine, Muscular, & Skeletal
Biology Review Today
Homeostasis
Cell membrane
Iodine molecules were small(diffused into the baggie), starch molecules were too big, (did not diffuse into water)
Chemical change (color changed)
EnergyTissue growth & repair
Energy, insulation & protection
Fats
PHYSICAL BREAKING DOWN OF FOOD!!
Occurs in the mouth and stomach.
CHEMICALLY BREAKING DOWN FOOD
BY ENZYMES (amylase in mouth, pepsin in stomach)
Mouth Stomach
Mouth Stomach and the Small Intestine
Small Intestine
Increases absorption of nutrients
a. Which part of the blood is responsible for carrying OXYGEN around the body?
b. What is the liquid portion of the blood called?
c. What is the disease fighting portion of the blood called?
d. What helps your blood clot?
e. In which blood vessel does DIFFUSION of oxygen and carbon dioxide take place?
f. Which blood vessel transports blood AWAY from the heart?
g. Which blood vessel transports blood TO the heart?
Red Blood Cells
Plasma
White Blood Cells
Capillaries
Arteries
Veins
Platelets
5. CIRCULATORY SYSTEM
R. Atrium
R. Ventricle
L. Atrium
L. Ventricle
Left atrium and ventricle
Right atrium and ventricle
Capillaries
Cell respiration
Gas exchange
Capillaries
Diffusion
Remember, inside the capillaries, there are red blood cells waiting to pick up the oxygen to carry it back to the heart, where it will go to the body.
e. Below is the pathway of air in the respiratory system. Fill in the missing organs:
Nose ___________ Larynx ____________ Bronchi ____________
Alveoli
Pharynx Trachea Bronchioles
Carbon dioxide, heat, water, urea, and salt
Sweat cools off the body!
Label each part of the Urinary System Diagram:
Sensory Neuron --> Interneuron --> Motor Neuron
This system coordinates with the Muscular system when you are in danger!!
b. Name the 3 parts of the brain: Cerebrum, Cerebellum, Medulla
Hormones
a. Bones are living ___________________
b. Bones make blood cells _________________
c. Bones do not store minerals like calcium and phosphorus ______________
