Study Notes
- Blood pressure must be sufficiently high so oxygen and nutrients are delivered to cells and waste products are removed
- Elevated arterial pressure can cause a hemorrhage in the brain
- Three factors determine blood pressure: the amount of blood pumped, the volume of blood in the vessels, and the heart rate
- The amount of bood pumped causes blood pressure to rise
- More blood in the vessels causes blood pressure to rise
- The heart beat rising causes blood pressure to rise
- Blood pressure can decrease after a heart attack
- In a circulatory collapse due to dehydration the pressure decreases and will likely cause a drop in arterial pressure
- The arterial pressure increases if the blood vessels constrict
Matching List
- A: Ventricular systole
- B: Auricular contraction
- C: Atrioventricular valves
- D: Myocardial relaxation
- E: Semilunar valves
Heart Valves
- The main function of the heart valves is to prevent blood reflux
Blood Pressure
- 120 mmHg systolic is the maximum blood pressure for an adult
High blood pressure
- High blood pressure results from increasing the volume of blood
Blood Analysis: Hematocrit
- In women, hematocrit reference values are 36%-46%
- In men, hematocrit reference values are 42%-50%
Blood Analysis: Leukocytes
- Leukocytes reference values are 4.0x10^3-10x10^3
Blood Analysis: Platelets
- Platelets reference values are 150,400 x 10^3
Blood Analysis: Glucose
- Glucose reference values are 70-110 mg/dl
Blood Analysis: Total cholesterol
- Total cholesterol reference values are around 190 mg/dl
Altered Hematocrit
- A person with altered hematocrit values are showing the value of altered hematocrit
High Fat Diet
- A person with a diet rich in fat is prone to suffering from atherosclerosis
Digestion
- Digestion stages include Insalivation, Stomach Action, Intestinal Absorption , Fecal Formation, Egestion
