Which of the following would increase blood pressure?
Group of answer choices
Increased parasympathetic activity
Decreased heart rate
Vasodilation of blood vessels
Increasing resistance in blood vessels
An example of a positive feedback mechanism is blood clotting in which certain clotting factors active other factors until a plug forms to stop bleeding. Is this process involved in homeostasis?
no, positive feedback mechanisms cannot regulate homeostasis
no, it is not a negative feedback mechanism
no, it does not fit into a classic "push-pull" action
no, because it does not result in restoring blood volume
O yes, because it is part of a bigger negative feedback mechanism to maintain optimal levels of blood volume.
E O O O O C
Which of the following is an example of positive feedback?
Arterial blood pressure homeostasis.
Blood glucose homeostasis.
None of the above
Blood pH homeostasis.
Blood oxygen content homeostasis.

- Which of the following statements about our heartbeat is incorrect? Group of answer choices Pulse rate of a person generally changes throughout the day. Each heartbeat has a pulse. Our pulse rate can be increased by exercise. Our pulse rate changes with age. The number of heartbeats increases while we sleep.arrow_forwardPart i) Label & describe what is happening at each letter in the following process. Part ii) List the 2 types of feedback systems. B A C Receptor IMBALANCE Control Center BALANCE D Effector IMBALANCE Earrow_forwardFigure 33.21 State whether each of the following processes are regulated by a positive feedback loop or a negative feedback loop. A person feels satiated after eating a large meal. The blood has plenty of red blood cells. As a result, erythropoietin, a hormone that stimulates the production of new red blood cells, is no longer released from the kidney.arrow_forward

O positive feedbackarrow_forwardOrder the following in the correct sequence that reflexes are trasmitted through the nervous system: brain stem integrates this and other information low pH detected by chemoreceptors affarent neuron sends signals to brain stem efferent neuron travels to the lungs breathing rate is increasedarrow_forwardTrue or false Blood pressure is a product of cardiac output and resistance. Blood pressure is lowest in the vena cava The pulse is felt at the large veins Arterioles are the most important vessels in regulation blood pressure. Veins and lymph vessels have valves Only arteries have smooth muscles Veins always carry deoxygenated blood.arrow_forward
- Describe in detail the negative feedback mechanism that regulates blood pressure. ANSWER SHOULD INCLUDE: Cardiovascular system response to a fall IN BP: Name location of receptors Afferent pathway - how signal is sent to CNS ( i.e. branch of ANS involved, name of neurotransmitters/ hormone) Name and location of control of control centre in CNS Efferent pathway - how signals is sent to effectors . Name and location of effectors How effected bring about change in BP LINK to BP equation Cardiovascular system response to a rise in BP ( AS BOVE )arrow_forwardWhich of the following happens in zero gravity due to the re-distribution of fluids in your body? you frequently feel the need to urinate your blood no longer clots properly when your skin gets cut your mouth becomes dry your lower legs become bloated and increase in circumference Due to the malfunctioning of certain systems in the inner ears in zero gravity, astronauts will frequently experience extreme mood swings have impaired hearing during a mission feel thirsty and drink more fliuds than necessary experience some dizziness and nauseaarrow_forwardA behavioral physiologist is studying the homeostatic control of blood pH. In a trial, a lizard runs on a treadmill for a set amount of time and the blood pH is measured. The blood pH drops as carbon dioxide is released into the bloodstream. Which component of the homeostatic feedback system is responsible for determining if the blood pH is far enough from normal that a response is necessary?

- 32°C Vein Artery 15°C 8°C 0-5°C Heat This example of a seagulls leg on a cold surface illustrates: O Blood shunting: which shunts heat from warm arteries into nearby cold veins O Acclimation; which will allow the gull to acclimate to lower temperatures where the brain does not register the cold any longer O Countercurrent blood circulation: which allows the temperature of the feet to stay just above freezing, while maintaining a warm core temperature Heterothermy: which keeps the blood at a constant temperature as it travels down the bird's legarrow_forwardA negative feedback system is one in which a variable is changed in the same direction as the original change that initiated the system the initiating variable is always reduced (made more negative) a variable is changed in the opposite direction to the original change that initiated the system two opposing variables are played against one other the initiating variable is always increased (made more positive)arrow_forwardWhich of the following is incorrect? Select one: Equilibrium requires a constant input of energy. Positive feedback is less common in nature than negative feedback. Homeostasis does not imply that a given variable is unchanging. Fever is an example of resetting a set point. Efferent pathways carry information away from the integrating center of a reflex arc.arrow_forward
