Study Notes
Anemia
- Folic acid deficiency anemia is a common preventable cause of anemia in China
- Loss of cell substance is called atrophy
- Hyperplasia is an increase in cell size
- Active hyperemia is a vascular reaction
- Passive congestion is a vascular reaction
- Platelets aggregation is a mechanism
- Warfarin inhibits factors II, VII, IX, and X in blood clotting
- Pregnant women are most affected by anemia globally
- Folic acid supplements prevent neural tube defects in newborns during pregnancy
- Three-year-old child skin injury from candle is called an ulceration
- Epidemiological triad includes agent, vector, environment
Hemoglobin
- Hemoglobin is a protein that transports oxygen in the blood
- Hemoglobin's structure, specifically the iron-containing heme part, is crucial for oxygen transport
- Hemoglobin contains two identical alpha and two identical beta chains within its structure.
Vitamins
- Vitamin B5 deficiency affects pyruvate dehydrogenase.
- Vitamin B5 is a water-soluble vitamin
Wound Healing
- Organization is a process after wound healing contends, but the injury site may have a prominent raised nodular scar over time
- Dehiscence is when wound healing fails to correctly close
- Keloid is an overgrowth of scar tissue which causes a prominent raised scar
- Organization and dehiscence can occur after injury
Communication
- Attentive listening, confidentiality, knowledge of the patient, and empathy are essential components for effective communication between a doctor and a patient
- Group communication is a type of communication occurring in a physiology lecture setting.
Allergies
- Histamine is a substance that likely causes nasal congestion and secretions in a cat dander allergy.
Blood
- Antibodies are a major part of the plasma proteins
- Antibodies constitute approximately 50% of plasma proteins.
- Antibodies are distributed unequally between plasma and serum.
- Antibodies contain at least two antigen binding sites.
Blood Components
- Hemoglobin content and hematocrit of a young man are 17 Gm/dl and 50%, respectively. MCHC is 32% (g/dl).
Genetic Conditions
- Hemophilia is a genetic disorder.
- If a male with hemophilia has a baby girl, there is a 75% chance that she is a hemophilia carrier.
Other
- Dialysis tubing is permeable to iodine but not to starch.
- Bicarbonate/carbonic acid buffer ratio is 20:1.
- Avidin is a protein that can affect biotin absorption in the small intestine when consumed in raw egg whites.
Other
- Blood-thymus barrier is formed from the presence of occluding junctions between adjacent type 1 epithelioreticular cells.
