Exam 3 Quiz Flashcards
What factors determine rate of pulmonary and systemic gas
Partial pressure difference of gases
Surface areal available for gas exchange
Diffusion distance
Molecular weight and solubility
What indicates the direction of gases at the pulmonary alveoli of the lungs?
Oxygen in, CO2 out
TX for gangrene if antibiotics don’t work
Hyperbaric oxygenation
Dominant method of CO2 transport in blood
Dissolved in plasma as bicarbonate ions
When blood pH drops, what happens to oxyhemoglobin and oxygen delivery to tissue cells
Oxyhemoglobin decreases and oxygen to the tissue increases
Most important factor that determines % of oxygen saturation in hemoglobin
Po2, Partial pressure of oxygen
Where is the rhythmicity center for respiration?
The medulla oblongata
Neurons of the pontine respiratory group transmit nerve impulses to the
Medulla
What causes lymph from small intestines to appear white?
Lipids
Left subclavian vein receives lymph from
The thoracic duct
Skeletal muscle and respiratory pumps are used in
Lymphoid, immune and cardiovascular systems

Thymi’s (Hassall’s) corpuscles
Name a function of the spleen
Removes worn out RBCs
An anti-microbial substance that promotes cytolysis, phagocytosis and inflammation
Complete proteins
Genetic recombination generates diversity in what part of the immune system?
Antigen receptors
Which cells have the greatest variety in the immune system
Lymphocytes
Site of sperm production
Seminiferous tubules
What hormone stimulates interstitial endocrine cells of testes to secrete testosterone?
(LH) Luteinizing hormone
What structure is posterior to the urinary bladder and anterior to the rectum and secretes an alkaline, fructose filled fluid?
Seminal vesicles
Which are produced and released from the ovaries?
Estrogen, progesterone and secondary ooocytes
What part of the uterus opens into the vagina?

Which hormone triggers ovulation
(LH) Luteinizing hormone

What is the difference between lymph and interstitial fluid?
The location
What is co-stimulation?
A secondary signal that immune cells use to activate an immune response to an antigen cell
Name one mechanism lymphatic vessles use to return fluid to the heart
Respiratory pump/ draw
What is the difference between innate and adaptive immunity?
Innate immunity a baby gets from the mother and is a general response to any antigen.
Adaptive immunity responds to specific antigens and remembers them.
What do help T cells do?
Help activate B cells and cytotoxic cells
Define genetic recombination
Recombining genes on T and B cells to produce new antigen receptors
What is an epitope?
The part of the antigen that the antibody attaches itself to
