A lab-glove kit drawn in soft colour — spray bottle, roll of tape and a sample bag held in gloved hands — and a photo of an anatomical heart model with its vessels and arteries.

Biology within Science & Education
Chemistry, Physics and Mathematics sit alongside, and Laboratory, Microscope and DNA have their own pages. Biology covers living things: anatomy, cells, plants, animals and the tools used to study them.
The sample kit
The drawing shows how a specimen is bagged and sealed, step by step. It fits a school lab-safety sheet, a field-work guide or a forensics lesson.
The heart model
A realistic plastic model with the aorta and coronary vessels in reddish brown. It suits anatomy slides, a cardiology clinic's page or a biology exam revision card, where a real-looking organ is clearer than a cartoon.
