Test questions 2 Flashcards
what is located on the anterior region of the body
patella
what pair of common anatomical terms is mismatched
inguinal/foot. (inguinal is groin)
what organelle is not involved in synthesis or packaging of proteins
lysosomes
what type of tissue functions as a protective barrier
epithelial tissue
in anatomical position, the body is
upright, arms at the sides, palms facing anterior
the skin is ___ to the bones
superficial
correct sequence of the path of air from the upper to lower respiratory tract
nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles
surface tension of the alveolar fluid is reduced by the secretion of ___ by lung cells
surfactant
exchange of oxygen and carbon dioxide occurs across the alveolar membrane by the process of
diffusion
contraction of the diaphragm and external intercostal muscles results in
a decrease in alveolar pressure
lung cancer causes what type of compliance
low
what condition causes the highest compliance
emphysema
what parts of the upper respiratory tract is a shared pathway for both food and air
pharynx
what prevents food from entering the air passage
epiglottis
gas exchange between the blood and the alveoli would be compromised by an increase in
membrane thickness
what happens normal expiration
the diaphragm and external intercostal muscle relax and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.
what happens in a normal inhalation
your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
when someone continuously holds his breath, eventually he will
automatically start to breath when the CO2 levels in the blood reach a high enough level
erythrocytes of the blood
transport oxygen and some carbon dioxide
what 2 vessels carry deoxygenated blood
pulmonary arteries and vena cava
the arteries are thicker and more elastic than the veins because
arteries are under greater pressure
a blood pressure might read 120/70. What is the highest number and what does it signify the heart is doing
systole and is the phase when the heart is contracting
what is function of lymphatic tissue
collect excess fluid, immune response, filtration of interstitial fluid
what is the consequence of increased hemoglobin in the blood
increased ability of the blood to carry oxygen to the tissues
