Here is the PowerPoint from yesterday. Just click on the link below:
Here are the notes I took in class to go along with the PowerPoint:
Slide 2:
arterioles are smaller arteries
venules are smaller veins
Slide 3:
do veins pulse? No!! They have a thin middle layer because they do not regulate blood pressure.
arteries constrict or dilate. (see page 292-293).
Slides 4-6:
Exchange of materials: FOG (read page 295) for more information.
F=Filtration
O=Osmosis
G=Gases (move by diffusion)
Slide 7:
Hormones affecting Blood Pressure. Look at the diagram and read page 309.
*know that the kidney excretes Na+ ions and water, which decreases blood volume and lowers blood pressure.
What are organs involved with blood pressure? liver, lungs, kidney…
Slide 8: The Renin-Angiotensin Mechanism
see page 310-311
involves the kidneys. When blood pressure decreases, the kidneys secrete renin.
Slide 9: Nervous mechanisms that regulate blood pressure
