Blood vessels are the channel like paths that carry blood throughout the body and our body contains around 60000 miles of blood vessels carrying blood to different cells and body
Different types of blood vessels --
- arteries
- veins
- capillaries
- arterioles
- venules
Importance of blood vessels
- Carry oxygen to the cells and remove CO2 out of cells
- Provide nutrients to cells and tissues

This figure shows the relationship between EDV and SV. Curve 2 is representatíve of a normal individual sitting on a bike, resting. There are two other curves illustrated and there are multiple points landmarked with a "o" and the letters "A to F". You can assume that the only changes in relevant variables are described in each question. If a variable is not mentioned you can assume that it has not changed. The starting point is "A". Select an appropriate pointif there was an increase in cardiac inotropy. 23 D. Stroke Volume (mL)Describe how cardiac performance is measured in cardiac output. In your answer, be sure to describe the role of stroke volume (SV) and HR by defining each and discussing factors that influence SV in particular both during acute exercise and following chronic exercise training.If activation of RAAS is the independent variable and arteriolar resistance is the dependent variable, which graph would best describe their relationship? Please thoroughly explain the effect on the dependent variable if the independent variable increases so I can fully understand the concept.

- Briefly describe the cardiovascular response to an increasing intensity exercise test. Be sure to mention the physiological basis for WHY these responses occur. Do this by discussing the changes in HR, SV, SBP, and DBP.Many of the subdivisions of the CPT manual in which cardiovascular codes are found contain notes. Additional parenthetical notes are sometimes included with the codes themselves in this section. Why is it important to pay attention to these notes? What aspects of cardiovascular system procedures make this even more critical than normal?Define blood pressure and describe and compare specific types (e.g. arterial, MABP, venous, PP). Include their expected values or ranges. Explain what happens to pressure when blood flows further away from the heart. During the rest period before starting an exercise routine where is most of the blood concentrated? Upon initiating exercise what happens to blood flow and pressure?
