Blood flow, lymph and regulation of the heart
Answers are for parents and teachers.
1
Explain in 3 sentences the difference between blood pressure and pulse.
Pressure is the force of blood on vessel walls (mmHg); pulse is artery vibration (beats/min); both depend on the heart.
2
Draw a scheme of nervous and humoral heart control.
Receptor → centre → sympathetic/parasympathetic nerve → heart; adrenaline, calcium → heart.
3
Write the importance of lymph circulation.
Returns excess tissue fluid to blood; lymph nodes filter microbes and produce lymphocytes.
4
Add 3 changes to your daily routine for heart health.
For example: more walking, less salty food, less screen time sitting, sleeping on time.
5
If you notice signs of stroke or heart attack, whom do you call and what do you say?
Call 103: what happened, address, signs; tell adults immediately and watch the patient without moving them needlessly.
