Is On HistoWeb

12. Objectives: Respiratory System
Functions of components of the respiratory system.
Histological structures in the succession of airways
Histological features in each part of the airways.
Cells in each part of the respiratory system & function.
Histological structure adaptation to function.
Explain the blood-air barrier.
Changes due to diseases.

13. Tasks: Respiratory System
Study the supplied diagrams and slides. Annotate each. Where possible, give the function of each labelled structure or cell.
Complete the table.
Describe the path of oxygen from outside the body until it takes part in a metabolic process, and the corresponding reverse path followed by carbon dioxide.
Make an annotated diagram of the complete respiratory system, indicating the function of each part.
Describe the histology seen in a cross-section for each of the following passages of the respiratory system:
Nasal cavities
Trachea
Bronchioles
Respiratory bronchioles
Alveolar duct
Alveoli
List the functions of each part of the respiratory system.
Name the cells present in each part of the respiratory system and the function of each.
Make an annotated diagram of the blood-air barrier, clearly indicating the components and surrounding cells and tissues.
Correlate each of the described histological structures with its corresponding view on a microscopic slide.
Complete the relevant slides in the practical workbook.

15. Objectives: Skin
Know the three layers of skin and the main tissue component of each.
Know the functions of skin and how it is modified in different parts of the body.
Know how skin is pigmented, and the function of pigmentation.
Know the structure, components and functions of the layers of skin (epidermis, dermis and hypodermis), and its derivatives.
Know the three modes of exocrine section, and give examples of each.
Know the glands present in skin.
Know the process of keratinization.
Know the distinct nervous endings present in skin (Meissner's and Pacinian corpuscles).

16. Tasks
1. List the various types of skin, the derivations of skin and the functions of each.
2. Make an annotated diagram showing the three main layers of skin and the structures found within each layer. Within each layer, indicate the component layers, where applicable. What are the functions of each layer and structure?
3. Correlate each of the described histological structures with its corresponding view on a microscopic slide.
4. Complete the relevant slides in the practical workbook.
