Question 1 - 10 Draw a picture of the heart and label the following: Visceral pericardium Parietal pericardium Myocardium Epicardium endocardium

Answer 1 – 10

Question 1 - 20 Draw a picture of the heart and label the chambers.

Answer 1 – 20

Question 1 - 30 Draw a picture of the heart and label the 4 tubes coming out of the heart AND the valves

Answer 1 – 30

Question 1 - 40 What are some structural differences between arteries, veins, and capillaries

Answer 1 – 40 Capillaries: thin walls (1 cell layer thick) Arteries: thick, muscular walls Veins: thin walls

Question 1 - 50 The RIGHT side of the heart is responsible for ________________ circulation. The LEFT side of the heart is responsible for ___________ circulation.

Answer 1 – 50 RIGHT = pulmonary LEFT = systemic

Question 2 - 10 What is the tube called that dumps into the right atrium?

Answer 2 – 10 Superior/inferior vena cava

Question 2 - 20 When the right ventricle contracts, what happens?

Answer 2 – 20 Shuts the right atrioventricular valve Opens the pulmonary semilunar valve

Question 2 - 30 Put the following in order of blood flow if you were to start at the RIGHT ATRIUM: Venuoles Right atrioventricular valve Aorta Left atrium Lungs Artery

Answer 2 – 30 RIGHT ATRIUM Right atrioventricular valve Lungs Left atrium Aorta Artery Venuoles

Question 2 - 40 True or false: Blood pressure is measured in veins.

Answer 2 – 40 FALSE

Question 2 - 50 Draw a picture of the heart and draw arrows showing the blood flow.

Answer 2 – 50

Question 3 - 10 What is the little flap called that prevents food from going down your trachea?

Answer 3 – 10 epiglottis

Question 3 - 20 What is the difference between a bronchus and a bronchiole?

Answer 3 – 20 Brochi = main branch that branches off of the trachea Bronchiole = smaller branches found in the lungs

Question 3 - 30 When you INHALE, what does your diaphragm look like? When you EXHALE?

Answer 3 – 30

Question 3 - 40 What organ has C-shaped rings of hyaline cartilage?

Answer 3 – 40 Trachea (windpipe)

Question 3 - 50 Put the following in order: Bronchioles Pharynx Nasal cavity alveoli Larynx Trachea Bronchi

Answer 3 – 50 Nasal cavity Pharynx Larynx Trachea Bronchi Bronchioles alveoli

Question 4 - 10 What is the difference between internal and external respiration?

Answer 4 – 10 External respiration: gas exchange between the blood and the outside of the body (air in the alveoli) Internal respiration: gas exchange between the blood and internal tissues

Question 4 - 20 How is oxygen transported within the blood?

Answer 4 – 20 Either attached to hemoglobin or dissolved in the plasma

Question 4 - 30 How is CO2 transported within the blood?

Answer 4 – 30 Attached to hemoglobin Dissolved in plasma as a bicarbonate ion

Question 4 - 40 How does air enter the lung?

Answer 4 – 40 The intrapulmonary volume increases, which creates low pressure within the lungs. Pressures move from high to low so air is sucked into the lungs.

Question 4 - 50 How is inspiration an active process?

Answer 4 – 50 It requires muscle contraction

Question 5 - 10 What is residual volume?

Answer 5 – 10 The volume that always remains inside the lungs and is never breathed in/out

Question 5 - 20 When taking a blood pressure reading, the pressure on the cuff when you hear the first sound is the ___________ pressure and the pressure when you hear the last sound is the ____________ pressure.

Answer 5 – 20 Pressure at first sound = systolic pressure Pressure at second sound = diastolic pressure

Question 5 - 30 Draw a picture of a graph showing the pressure changes that occur as blood circulates systemically within your body.

Answer 5 – 30 The blood pressure decreases as you get closer to the heart

Question 5 - 40 What is tidal volume?

Answer 5 – 40 The volume of air that you breathe in and out during normal, quiet breathing

Question 5 - 50 If you are reading this slide, that means you went home and practiced. Write the word “pertussis” at the top of your test for extra credit. Do not share this with anyone. YOU are the one who took the time to review outside of class, so don’t be a doormat for those who were too lazy to take advantage of their resources.
