|
Thoracic Cavity |
- Has 3 smaller cavities Pleural - Surrounds each lung Mediastinum - central portion between lungs Pericardial - Surrounds the heart |
|
|
Abdominopelvic Cavity |
Goes from diaphragm to groin Diaphragm separates Thoracic from Abdominopelvic Abdominao - Contains spleen, liver, stomach, gallbladder, SM intestine Pelvic - Contains reproductive organs, bladder, some Lg Intestine |

Sweat glands 2 types Eccrine Glands Apocrine Glands |
|
|
Osteoblasts |
Bone builders and repair Create and secrete collagen fibres for ECM |
|
|
Osteocytes |
Mature bone cells Maintain metabolism by exchanging nutrients and waste with blood |
|
|

|
|
2 Types of Epithelium Cells - Purpose |
Covering/lining glandular` |
|
|
Definition of Membranes |
Flat sheets of pliable tissue that covers or lines a body part |
|
|
Repair Steps in Bones |
- Phagocytes remove dead bone tissue
-Chondroblases form cartilage and bridge the break
-Osteoblasts convert fibrocartilage to bone tissue |
|
|
Form of Epithelium Cells |
Closely packed Rests on basement membrane Formed in layers High capacity for renewal Nerve supplied |
|
|
Cartilage |
