Digestive, Circulatory and Respiratory Review

  1. What is the function of the cardiovascular system?

Carry oxygen, glucose, and other needed materials to cells.
Carry waste products away from cells and fight disease.
2. The upper chambers of the heart are called the:
Left and Right Atrium.
3. The function of the atrium is to:
Receive blood that comes into the heart.
4. The lower chambers of the heart are called the:
Left and Right Ventricles.
5. The function of the ventricle is to:
Send blood out of the heart.
  1. Blood vessels that carry blood away from the heart are
called__Arteries______.
  1. Blood vessels that carry blood to the heart are called
Veins
  1. The tiny blood vessels that reach every cell of the body
are called______Capillaries______.
  1. The main parts/components of blood are:
__plasma______.
__platelets______.
__red blood cells______.
__white blood cells______.
10.The part/component of the blood that carries oxygen is :
red blood cell
11. What substance in the blood helps to attract oxygen
molecules and gives blood it’s bright red color?
Iron
12. The functions of the respiratory system is:
Bring oxygen into the body
Remove carbon dioxide and other from the body
Help fight disease
13. Define the parts of the respiratory system.
  • Nasal Cavity-warms & filters air as it enters body
  • Trachea-air passageway from head to lungs
  • Pharynx- the throat open at the back of mouth
  • Larynx--(voice box) - upper part of trachea
  • Epiglottis-flap of skin that covers the larnyx
  • Bronchi-tubes that carry air from trachea to lungs
  • Bronchioles-smaller tubes that branch from bronchi
  • Alveoli-grape-like clusters at the end of bronchioles. The site of blood the gas exchange
14. What is the blood gas exchange and where does it occur?Gas exchange occurs in the alveoli in the thin walls of the capillaries. Co2 for O2
15. What is pneumonia and how does it affect the blood gas
exchange?Pneumonia is an infection in the lungs that causes the lungs to produce large amount mucus that covers the alveoli and prevents the blood gas exchange.
16. What is the function of the digestive system?To break food down into small molecules that can be absorbed into the body.
17. List the path of food through the digestive system starting with the mouth.Mouth-esophagus- stomach-small intestine- large intestine-rectum.
18. What nutrient is broken down in the mouth? starch
What nutrient is broken down it the stomach?protein
Where are the rest of the nutrients broken down?Small intestine
19. What is the force that moves food through the digestive system? Smooth muscle contractions-peristalsis
