How do we bring air into our lungs?

Contraction of the diaphragm and muscles in between our ribs, this opens up the lungs and decreases the air pressure which pulls air into them
100

What are the 3 types of blood vessels, and what are their functions/directions?

Arteries carry blood away from the heart, veins carry blood back to the heart and have valves in them, capillaries connect arteries and veins

100

Which enzyme is produced by our salivary glands?

Amylase. What does it digest?

100
What is the purpose of the kidneys?

Filters the blood to remove excess water, salts, drugs, and urea

100

How do we speak?

Passing air through our larynx causing our vocal cords to vibrate

200

Which molecule carries oxygen throughout our bodies?

Hemoglobin

200

Which chamber of the heart receives freshly oxygenated blood from the lungs?

The left atrium

Bonus: Which blood vessel delivers blood to the left atrium?

200
What would happen if the pH of chyme was not adjusted before it entered the small intestine?

Digestive enzymes like lipase and amylase would not function as needed, possible damage to the tissues of the small intestine

200
Which organ of the digestive system do the kidneys closely rely upon to keep our blood clean?

The liver

200
Amylase, pepsin, and lipase digest _____, ______, and ______ respectively

Carbohydrates, proteins, lipids/fats

300

What structure prevents food from entering our lungs?

The epiglottis 

300

What is the purpose of the right ventricle?

Pumps deoxygenated blood out to the lungs

300

T/F: Peristalsis is an example of chemical digestion

False - peristalsis is the contraction of muscles that moves around our food as it is digested, this is mechanical

300
What is the order of organs through which urine passes through the body?

Blood enters the kidneys, passes through the ureter into the bladder, then ultimately out of the body through the urethra

300
Describe the stages of a heart contraction

Relax - blood fills heart

First contraction - blood pumped into ventricles from atria

Second contraction - blood pumped out of the ventricles

400

Why are red blood cells good at exchanging CO2 and O2?

Hemoglobin can bind both gases, but binds CO2 more loosely than O2, allowing it to release the CO2 at the lungs

400

Describe the flow of blood throughout the heart, starting with the vena cava and ending with the aorta

I & S Vena Cava -> Right Atrium -> Right Ventricle -> Pulmonary Artery -> Lungs -> Pulmonary Veins -> Left Atrium -> Left Ventricle -> Aorta

400

How does our small intestine absorb nutrients?

Lined with villi that have a high surface area

Active transport of nutrients

400

Identify the parts of the nephron that perform the following steps:

Filtration occurs in the ____________

Reabsorption occurs in the ___________

Bowman's capsule, Loop of Henle or Proximal Convoluted Tubule

400

What are the 6 "nutrients" we discussed?

Water, Vitamins, Minerals, Fats/Lipids, Proteins, Carbohydrates
