Lymphatic, Respiratory, & Digestive Systems Flashcards
Define: internal respiration
At systemic capillaries, gas exchange is made between the blood and tissue cells within the body
What two parts are used only as passageways in digestion? (2)
- Esophagus
2. Pharynx
What do you call a cluster of lymphatic tissue?
Lymph node
List 2 functions of the spleen. (2)
- Cleans and filters blood
2. Destroys worn-out erythrocytes (red blood cells)
Define “thymosin” and state its main function. (2)
- Hormone produced in the thymus
2. Programs certain lymphocytes
State the differences between the left and right bronchi. (3)
The right bronchus is
- Wider
- Shorter
- Straighter (superior to inferior)
Which bronchus is the main bronchus?
Right bronchus
Define: passive immunity
Immunity obtained through the antibodies from another human or animal donor
List the 2 antimicrobial proteins. (2)
- Complement proteins
2. Interferons
What is inflammation is when is the response triggered? (2)
- Non-specific response
2. Occurs when body tissue is injured
List the 4 indicators of inflammation. (4)
- Pain
- Swelling
- Redness
- Heat
What is the body’s thermostat and where is it located? (2)
- Hypothalamus
2. In the brain
What is hypothermia?
Extremely low body temperature resulting from long periods of cold exposure
What is hypothermia? (1)
Extremely low body temperature resulting from long periods of cold exposure
State the 4 distinct events that occur to make the respiratory system function. (4)
- Pulmonary ventilation
- External respiration
- Respiratory gas transport
- Internal respiration
What is the adaptive response and 3 important aspects of it? (4)
- Immune system’s response to a threat = mounts an attack
- Anti-gen specific
- Systemic
- Has “memory” = recognizes and mounts a stronger attack on previously-encountered pathogens
