100 - QWhat is pulmonary

circulation & systemic circulation?

Which side of the heart does each?

100 - APulmonary circulation: blood from right side of heart to lungs and back.

Systemic circulation: blood from left side of heart to body and back.

200 - QPractice labeling all the parts of the heart!

200 - ANote: you do NOTNeed to know the names of the valves.Just be able to label “valve” forEach.

300 - QWhich side of the heart has oxygenated blood?

300 - ALEFT!

400 - QDefine White blood cells

400 - AWhite Blood Cells (WBCs) fight off pathogens like viruses & bacteria to keep you healthy!

500 - QWhat type of vessels have valves?

500 - AVeins have valves!

Arteries and capillaries don’t

100 -QWhat are the four parts of blood and their

functions?

100 - ARed blood cells: carry oxygen/carbon dioxide.White blood cells: fight infections.Platelets: helps blood clot.Plasma: liquid part of blood, has dissolved

nutrients and waste.

200 - QIs this capillary found in the body or in the

lungs? How do you know?

200 - AIt is found in the body because oxygen is being delivered. (also there are

no visible alveoli).

300 - QDefine arteryCapillary Vein

300 - AArtery: blood flows away from the heart in

these vessels; most contain oxygenated blood (except pulmonary artery)

Capillaries: gas exchange occurs between cells & blood here

Veins: blood flows back towards the heart in these vessels; most contain deoxygenated blood (except pulmonary vein); contains valves to keep blood moving one way

400 - QDefine atriumVentricleValve

400 - AAtrium: upper chamber of heart; collects blood

Ventricle: lower chamber of heart; pumps blood

Valve: one-way doorway to prevent the backflow of blood; found in heart & veins

500 - Q

What is gas exchange and how is it different in the lungs and in the body?

500 - A

In the lungs, oxygen is being picked up and carbon dioxide is being dropped off.

Gas exchange is the exact opposite in the cells of the rest of the body; oxygen gets dropped off and CO2 gets picked up.

100 - QGive the major organs/structures of each body system:

Excretory systemDigestive system

100 - A Give the major organs/structures of each body

system:

Excretory system – bladder, kidneysDigestive system – stomach, intestines

200 - QCompare and contrast the job of the atria and ventricle

200 - ACompare and contrast the job of the atria and ventricle

The atria collects blood

The ventricles pump blood out of the heart

300 - QHow is the gall bladder related to the villi?

300 - AThe gall bladder stores bile. Bile is used to help break down fats in the small intestines so that they can be absorbed by the villi.

400 - QHow is the alveoli related to the circulatory system?

400 - AHow is the alveoli related to the circulatory system?

The alveoli are surrounded by capillaries from the circulatory system. When air moves into the alveoli, oxygen is absorbed into the capillaries and carbon dioxide is diffused into the alveoli from the capillaries.

500 - QIf your valves in your heart stop working well, what will happen?

500 - AIf your valves in your heart stop working well, what will happen?

Blood will be able to go backwards in the heart (for example, some blood from the ventricle will go back into the atrium). The result will be that the heart will not work as well to be able to pump blood.

100 - QLabel the following:

100 - A

200 - Q What happens in the alveoli?

200 - AGas exchange! Oxygen is picked up by the blood and carbon dioxide is released.

300 - QDescribe inhalation and exhalation.

300 - ADuring inhalation, your rib muscles contract and make your rib cage bigger. Your diaphragm contracts and pulls in air. When you exhale, the diaphragm relaxes, the rib muscles relax, and you expel air through your nose/mouth.

400 - Q What systems work together for respiration?

400 - AYou breathe in through your respiratory system, but then the oxygen is picked up by the blood and delivered throughout the body via the circulatory system.

500 - QWhat is cellular respiration?

500 - ADuring cellular respiration your mitochondria use oxygen and glucose (sugar) from your food to make energy in the form of ATP. The waste product is CO2, (and a little bit of water).

100 - QA group of tissues working together is a

100 - AOrgan!

200 - QRed blood cells….

200 - ARBCs Carry oxygen!

300 - QPlatelets…

300 - APlatelets… help clot the blood

400 - Q

If your white blood cell count is low, what would happen?

400 - AIf your white blood cell count is low, what would happen?

You are more prone to infection (remember that white blood cells fight pathogens/infection).

500 - QOther than the veins, what other part of the cardiovascular system has valves?

500 - AOther than the veins, what other part of the cardiovascular system has valves?

THE HEART!!!
