Human Physiology Charts, School Education

Quick Answer: Human Physiology Charts are school wall charts that explain how the human body works, showing processes such as digestion, breathing, blood circulation, reflex action, kidney filtration and hormone control as labelled flow diagrams. They are used in secondary biology.

Processes Rather Than Parts

Physiology charts show the body in action. A circulation sheet traces double circulation: from the right side of the heart to the lungs and back (pulmonary circulation), then from the left side to the body and back (systemic circulation). A digestion sheet follows food through the enzymes that act on it in the mouth, stomach and small intestine, and the absorption of nutrients through the villi.

Other typical topics include the mechanism of breathing (diaphragm and rib movements changing chest volume), gas exchange in the alveoli, the reflex arc from receptor to spinal cord to effector, filtration and reabsorption in the nephron, and the endocrine glands with the hormones they release. Arrows and numbered steps make these processes easier to follow than a paragraph of text.

Applications

• Explaining double circulation and the path of blood
• Teaching the mechanism of breathing with a bell jar model
• Reflex action lessons with a simple knee-jerk demonstration
• Revision of processes for examinations

Specifications

Care & Handling

• Hang physiology sheets in the order the processes are taught, so students can follow one system into the next.
• Keep the flow arrows readable: avoid pinning through the diagram or hanging other notices over it.
• Store flat or loosely rolled in a dry place.

Why Choose LabEquip

Biology departments commonly order these with the Human Body Charts on anatomy, and some add torso or organ models from the anatomy models range. Orders go through the LabEquip contact page.

Frequently Asked Questions

What is double circulation?

Blood passes through the heart twice in one complete circuit: once through the pulmonary circulation to the lungs to collect oxygen, and once through the systemic circulation to deliver it to the body. This keeps oxygenated and deoxygenated blood separate.

How does breathing work?

When the diaphragm contracts and flattens and the ribs move up and out, chest volume increases, pressure falls and air flows in. When they relax, the volume decreases and air is pushed out.

What is a reflex arc?

The pathway of a rapid, automatic response: a receptor detects a stimulus, a sensory neuron carries the impulse to the spinal cord, a relay neuron passes it on and a motor neuron carries it to an effector muscle, often before the brain is aware.

How does the nephron make urine?

Blood is filtered in the glomerulus into Bowman’s capsule, useful substances such as glucose and most of the water are reabsorbed along the tubule, and the remaining fluid with urea and excess salts passes on as urine.

What do physiology charts show about hormones?

They usually show the main endocrine glands, such as the pituitary, thyroid, adrenals, pancreas and gonads, with the hormones each releases and what those hormones control, such as growth, blood sugar and metabolism.

How can the charts be used with simple demonstrations?

Pair the breathing sheet with a bell jar and balloon model, the reflex sheet with a knee-jerk test, and the digestion sheet with a starch and iodine test before and after adding saliva.
