3. What does the systolic value represent?
- When the atria relaxes
- When the ventricles contract
- When the atria contracts
- When the ventricles relax
4. Which of the following is not an example of negative feedback?
- When nerve signals are transmitted, presence of sodium ions cause the membrane potential to be changed. The change in potential allows more sodium ions through
- When BP increases, receptors send a message to the brain. The brain then causes the heart rate to decreased and the blood vessles to constrict. BP falls as a result.
- If external body temp. decreases , heat is produced by shivering, hairs on skin stand up to insulate, and arterioles constrict to avoid heat loss.
- If water conc. of blood falls, ADH production is increased so less water is lost in urine
