Procedure
Part A:
Respiratory System

• Answer questions 1-8 in Part A of the Lab Report.
• Use this image to answer questions 9-13 in Part A of the Lab Report.

The image shows the opened thoracic cavity and neck of a diagram of a fetal pig. The letter A is pointing to a structure that is found on either side of the heart. These 2 respiratory organs occupy most of the thoracic cavity. The letter B is pointing to a hollow muscular enlarged organ in the upper part of the throat found above the structure that the letter C is pointing to. The letter C is pointing to a hollow pipe surrounded by rings of cartilage. The letter D is pointing to a gland that is normally butterfly shaped and surrounds the trachea. The letter E the organ that pumps blood and is located in the middle of the thoracic cavity.

• Use the list of organs provided here to answer questions 14-21 in Part A of the Lab Report. Use the Clickable image is in the "Respiratory System" section of the lab manual for help with these questions.

Image is a list of words; Alveolar duct, Alveoli, Bronchiole, Bronchus, Larynx, Nose, Pharynx and trachea.

• Answer the remaining questions in Part A of Lab 11 Lab Report.

Part B:
Breathing Rate

• Take your breath rate by gently placing your hand on your chest and count the number of inhalations or exhalations you take in one minute. You may use a watch or cell phone timer to count the 60 second interval.  
• Record your breath rate in the table below.  
• Take your breath rate two more times and record in the table below.  
• Calculate the average of the breath rates you measured and record the average in the table below.
• For the average, add the three trial values and divide by three.

Table to complete asks for the Breath Rate in BPM for Trial 1, Trial 2 and Trial 3 and then the average of the 23 trials.

Part C:
Circulatory System

• Answer questions in Part C of the Lab Report
• Use this image to answer questions in Part C of the Lab Report.

Image shows an anterior view of the heart. The letter A is pointing to a large red blood vessel on the top, middle of the heart. It is attached below to the left atria and above it branches off. The letter B is pointing to a large blue blood vessel is leading from the top of the image into the right atria. The letter C is pointing to a blue blood vessel that is on the top and middle of the heart. It is leading from the right ventricle and then branches off to the left and right. The letter D is pointing to two small red blood vessels on the hearts right side that lead into the left atria. The letter E is pointing to a space on the upper right side of the heart (left side in the image). The letter F is pointing to the space below the letter E. The letter G is pointing to one of the two blue branches coming off of letter C. The letter H is pointing to the upper space on the hearts left side (the right side of the image). The letter I is pointing to two small red blood vessels on the hearts left side that lead into the left atria. The letter J is pointing to the space below the letter H. The letter K is pointing to the lower tip of the heart.

• Use the list of organs provided here to answer questions 47-57 in Part B of the Lab Report.
Starting with the right atria, place the following in the order through which the blood will flow. Start by selecting “Right Atria” for number 47 and continue from there.
Use the Clickable image in the "Flow of Blood section"

Image is a list of words that read, Aorta, capillary bed of the lungs, capillary bed of the body, left atria, left or right pulmonary artery, left ventricle, pulmonary veins, pulmonary trunk, right atria, right ventricle, and superior or inferior vena cava.

• Answer the remaining questions in Part  of the Lab Report.

Part D:
Heart Rate & Pulse

• Take your pulse at the wrist by using two fingers (not the thumb) and gently pressing them against the thumb-side of the wrist on the palm side.
• Record your pulse in the table below.  
• Take your pulse two more times and record in the table below.  
• Calculate the average of the heart rates you measured and record the average in the table below.
• For the average, add the three trial values and divide by three.

Table to complete asks for the Pulse in BPM for Trial 1, Trial 2 and Trial 3 and then the average of the 23 trials.

After you have submitted your Lab Report Via Google please go to Blackboard, select the Lecture & Lab Materials folder for this week and then select "Lab 11 Lab Report: Post Statement here when completed". Select "Write Submission" and type in "I have submitted my Lab Report Via Google docs"
This will allow me to enter a grade that you can see on Blackboard in your grade book for each lab.
