Medical (Nursing) Charts-II, School Education

Quick Answer: Medical (Nursing) Charts-II is the second part of a series of nursing physiology charts, wall diagrams explaining how body systems function, such as blood and circulation, breathing, digestion and kidney function, for nursing and health science teaching. It follows the anatomy foundation of Part I.

From Structure to Function

Part II of a medical nursing series typically moves from where organs are to what they do. Blood sheets show the components of blood (plasma, red cells, white cells and platelets) and the ABO and Rh blood groups. Circulation sheets show the chambers and valves of the heart, the pulmonary and systemic circuits, and how blood pressure arises from the heart’s contraction and the resistance of the vessels.

Respiratory sheets in a set of nursing physiology charts explain ventilation and gas exchange in the alveoli, digestion sheets follow enzymes and absorption along the gut, and renal sheets show the nephron filtering blood and adjusting water and salts. For nurses these processes explain routine observations, such as why a dehydrated patient passes little urine or why the pulse quickens with fever.

As with the other parts, the titles included in Part II vary by edition and are worth checking against the course plan.

Care & Handling

• Hang the circulation and blood-group sheets of Part II near the skills station where pulse and blood pressure are practised.
• Sleeved or laminated copies suit skills labs, where hands are often still wet from hand-washing practice.
• Mark each sheet “Part II” on the back and store the set in its own tube.

Specifications

Applications

• Physiology lessons in nursing and paramedical courses
• Explaining the basis of observations such as pulse, blood pressure and urine output
• Teaching blood groups and transfusion compatibility
• Revision before semester examinations

Frequently Asked Questions

What are the components of blood?

Plasma, a straw-coloured fluid making up just over half the volume, carries dissolved nutrients, hormones and wastes. The cells are red blood cells, which carry oxygen, white blood cells, which fight infection, and platelets, which help blood to clot.

Why is O negative called the universal donor?

O negative red cells carry no A, B or RhD antigens, so they are unlikely to be attacked by a recipient’s antibodies. In emergencies they can be given before the patient’s blood group is known, although matched blood is preferred.

What produces blood pressure?

Contraction of the left ventricle pushes blood into the arteries, and the resistance of the vessels keeps the pressure up. The higher (systolic) reading is taken during contraction and the lower (diastolic) reading when the heart relaxes between beats.

How do the kidneys control water balance?

Each kidney has around a million nephrons that filter blood and then reabsorb water, glucose and salts. When the body is short of water, the hormone ADH makes the tubules reabsorb more, producing a small volume of concentrated urine.

Where does gas exchange take place in the lungs?

In the alveoli, tiny air sacs surrounded by capillaries. Oxygen diffuses from the air into the blood and carbon dioxide diffuses out, across walls only one cell thick.

Why is physiology taught after anatomy?

Function makes sense only once structure is known. After learning where the heart, lungs and kidneys are, students can follow how they work together, which is the basis of observing and caring for patients.
