Flashcards in Respiration And Circulation Review Deck (37):
What are the organs of the upper respiratory tract and lower?
Upper-nasal cavity, pharynx, trachea, larynx, epiglottis, esophagus
Lower-trachea, larynx, main bronchi, secondary bronchi, visceral pleura, parietal pleura
Be able to label the upper and the lower respiratory tract diagrams
What is the function of mucus?
Mucus protects the lungs from getting tiny particles into it like dust, dirt, germs, and pollen
What is the function of Cilia?
It traps smaller dust and bacteria
What are goblet cells?
It secrets mucus in order to protect the mucous membranes where they are found.
What is the pathway of air from the environment to the alveoli (organs involved)
Thorough the nasal cavity, pharynx, larynx, trachea, bronchi, alveoli
Approximately how many alveoli are there in the lungs? Why are there so many?
300 million alveoli
It increases the surface area in the lungs for more gas exchange
How do we make sounds?
We make sounds with our vocal chords. Our vocal chords stretch and loosen up making the high and low sounding voice.
What muscle are involved in breathing? What are their functions?
The diaphragm and the muscle associated with the ribs
The diaphragm contracts and allows the lungs to take in more air or grows bigger and pushes the air out of the lungs. The muscles with the ribs tighten pushing air out of the lungs or the raising the rib cage or expands, allowing air in the lungs.
Define internal and external
External-situated on the outside
Internal-situated on the inside
Define cellular respiration
The process by which a cell releases energy stored in the nutrients specifically glucose
What are the three main parts of the of the circulatory system?
The heart, blood vessels, and blood
List the functions of blood
-Transports substances to lungs and body
-carries nutrients from the digestive tract
-is a storage site to the rest of the body
What are the four components of blood and in what percentage do they exist?
Leukocytes and platelets-1%
What are the functions of each component of blood?
Plasma-regulates body temp helps with clots
Platelets-aid in blood clotting to protect wounds
erythrocytes(RBC)-contains hemoglobin, an iron-containing molecule, for building and carrying oxygen.
erythrocytes with type A surface antigens, plasma with anti -B antibodies
Erythrocytes surface type B antigen, plasma with Anti-A antibodies.
Erythrocytes with both type A, type B surface antigens, plasma with neither
Erythrocytes with neither type A/type B surface antigens, plasma with both Anti-A and anti-B antigens
What is the RH factor?
RH is an antigen found in blood plasma
Know the rules of blood transfusions.
Define agglutination? What is another term for agglutination?
Agglutination, also know as clumping, is the process that occurs if an antigen is mixed with its corresponding antibody.
structure and function of arteries
-lead blood away from heart
-thick rigid elastic wall
-carry oxygen rich blood (except the pulmonary artery)
-smooth inner lining
Structure and function of vein
-lead blood to heart
-carry oxygen poor blood (except pulmonary vein)
-thinner more flexible walls
-have valves to prevent back flow.
Structure and function of Capillaries
-running along cells of all body tissue
-cell thick wall of efficient exchange of fluids
-work as a network
What are the smallest arteries know as? Smallest veins?
Arterioles and venules
Which artery carries deoxygenated blood?
Which vein carries oxygenated blood?
Which is the most rigid artery? Why?
Where is the easiest place to find an artery? Why?
The neck is the easiest place to find a pulse because thats where the biggest artery is located
What are varicose veins?
Swollen and enlarged veins that usually occur on the legs and feet
What are the upper chambers of the heart know as? Lower chambers?
Upper = atrium
Lower = ventricles
What divides the left and the right sides of the heart?
Which carries deoxygenated blood away from the right ventricle of the heart, to the lungs and returns to the left atrium and ventricle of the heart with oxygenated blood.
system that carries blood away from your heart, delivers it to most of your organs and tissues, and returns it to your heart again.
Label the heart parts
