Terms in this set (37)
The functional unit of the Respiratory System is
Which of the following is the last (caudalmost) structure included in the UPPER respiratory tract?
Which medical term means the "throat"
The functional unit of the Cardiovascular System are
the heart and vessels
The QRS complex on a normal, Lead II ECG (EKG) represents
Which of the following is usually not associated with the 2nd Line of Defense?
Which of the following corresponds to immunity involving lysozymes and phospholipases?
Sweat, tears and Saliva
Which of the following cells are most likely to contribute to initiating the inflammatory response?
Mast cells: they release histamine (vasodilator) and heparin (anticoagulant) at the site of injury/infection/ or trauma which contributes to the inflammatory response.
The 3 essential functions of the nasal cavity are to
humidify, warm, filter air
In the image below, "B" represents
Which of the following in blood is NOT involved in triggering the chemoreceptors that would enable an animal to regulate or adjust respiratory patterns?
The higher the CO2 level in the blood, the
lower the blood pH.
When placing an endotracheal tube into the trachea of animals, which structures does the tube have to go between and through?
between the arytenoid cartilages and through the glottis.
Which of the following is a leaf-shaped musculocartilaginous structure that projects from the larynx and functions like a trapdoor when swallowing?
Which of the following muscles are responsible for EXpiration?
internal intercostal muscles and abdominal muscles
Exchange between inhaled oxygen and the carbon dioxide from the red blood cells in capillaries occurs at the alveolus and is known as internal respiration.
Internal respiration occurs within the body's tissues, at capillary beds where oxygen and carbon dioxide are exchanged. External respiration occurs between external oxygen in the alveolus and the carbon dioxide from the RBCs in the lung capillaries (at the alveolar-capillary interface).
Which of the following muscles are responsible for INspiration?
external intercostal muscles + diaphragm
The trachea branches into the
left and right bronchus.
Mechanical control of respiration is determined by mechanoreceptors found in which of the following?
smooth muscle of the trachea and lower respiratory tract
The space or area between the lungs is called the
In the image below, #1 is the
In the image below, "A" refers to a/an/the
Which region of the brain can control your respiration?
medulla oblongata in the brain stem
In the image below, #2 is the
What structure divides the rostral part of the pharynx into the oropharynx and nasopharynx?
What type of epithelium lines the upper portion of the respiratory system and plays an important role in the body's defense mechanism?
Pseudostratified ciliated colmnar epithelium
The alveolus is able to exchange oxygen and carbon dioxide with capillaries because it is one cell layer thick and is composed of simple squamous epithelium.
The single cell layer alveolus (w/simple squamous epithelium) allows diffusion of CO2 and O2.
Which of the following spaces is behind (caudal) the soft palate and dorsal to the larynx?
The functional unit of Immunity and Defense are
leukocytes, immune cells, and antibodies.
What 2 anatomical similarities do fishes and humans have in common?
Back bone, Skulls
What features did the creature Dr. Shubin set out to find, have or was expected to have?
limbs with 2 bones, little bones and digits
Dr. Shubin visited a woman whose genes expressed the phenotype (physical traits) of what fish feature?
During development, swellings in the embryo called gill arches become
components of the gill apparatus in fishes and the lower jaw, middle ear and voice box in humans.
How does human development of testes mirror that of fishes during embryonic development?
They start out in the chest near the heart in both.
The gene that was discussed and present in many terrestrial animals that controls the formation of digits (number and morphology) in both terrestrial animals and aquatic is called
In general what can we conclude about all the terrestrial vertebrates and their limbs in respect to the team's findings in the earliest fishes to come onto land?
Terrestrial vertebrates evolved from Tiktaalik as seen in the limbs
