What are the parts of the CV system?
These arteries have a lot of connective tissue
- Elastic arteries
- Those closest to the heart
- like the aorta and pulmonary arteries
Exchange of nutrients, wastes and gases happens here
These join to make veins
What is normal resting heart rate?
What is the effect of age on heart rate?
- Resting - none
- Maximum - decreases
What is End Diastolic Volume?
What is End Systolic Volume?
How do you calculate stroke volume?
What is Diastolic Filling Volume?
- 70 ml
- Blood which goes from atria to ventricle during diastole
How do you calculate cardiac output?
What factors affect stroke volume?
- amount of blood in ventricle
- force of contraction
- aortic pressure
How do you calculate venous return?
What is the function of the heart?
- generate pressure to maintain circulation
- overcome resistance
Why is the right ventricle weaker?
It has to overcome less resistance
Where does the lesser circulation go?
right ventrical to lungs to left atrium
The pulmonary and systemic circulations are arranged in this
Within the greater circulation, capillary beds are arranged in this
This is where blood meets most resistance
What does systolic pressure mean?
Pressure of blood exerted on arteries while heart is in systole
What is blood pressure in lesser circulation?
25 / 10
What is the pressure gradient in systemic circulation?
- 93 mm Hg
- MAP - pressure in right atrium
How does old age affect blood pressure?
- blood pressure increases
- cuz kidneys change
- and arteries harden
How do you calculate Vascular Distensibility?
increase in V / (increase in P x original V)
These vessels have high compliance
These vessels have low compliance
What is the formula for compliance?
- distensibility x volume
- "It is the total quantity of blood that can be stored in a given portion of vasculature for each mmHg rise in pressure"
