- What is hypotonic?
- a 1. The dorsal cavity which contains the spinal and cranial cavity
2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities

- c 1. Blood- plasma, RBC, WBC and platelets
2. Areolar- Subcutaneous. Connects skin to muscles. Mucous membranes
3. Adipose- Subcutaneous. Sores excess energy in fat. (insulation)
4. Fibrous- Tendons and ligaments and dermis of skin (strong)
5. Elastic- Walls of large arteries and alveoli in lungs (promotes normal exhalation and helps maintain blood pressure)
6. Bone- Support the body, protect internal organs, store calcium and contain and protect red bone marrow
7. Cartilage- Wall of trachea to keep airway open, on joint surfaces to prevent friction, tips of nose and outer ears. Absorbs shock between vertebrae

5 Multiple Choice Questions
- Requires energy of mechanical pressure. Water and dissolved materials are FORCED through a membrane from an area of higher PRESSURE to an area of lower PRESSURE
(Example: formation of tissue fluid and the first step in the formation of urine)
- Nucleus is within the cytoplasm and has a nuclear membrane with nucleoli and chromosomes of the cell. Nucleolus is where DNA and all genetic info for human traits lies.
- Serous membranes are in closed body cavities where the serous fluid prevents friction between the two layers of the serous membrane.
---Thoracic cavity: partial pleura lines chest wall and cisceral pleura covers the lungs.
---Pericardial sac: parietal pericardium lines the fibrous pericardium and the visceral pericardium covers the heart muscle.
---Abdominal cavity: peritoneum lines the abdominal cavity and mesentary covers the abdominal organs
- 1. Epithelial membranes
2. Connective Tissue membranes
- the response to stimuli does not stop but rather keeps the sequence of events going. (requires an external brake)
EX: cervical stretching during childbirth
5 True/False Questions
What are the two types of epithelial membranes? → Serous membranes: line some closed body cavities and cover the organs in those cavities (thoracic and abdominal cavities) CAVITIES THAT AREN'T OPEN TO AIR
Mucous Membranes: line the body tracts that have openings to the environment and have a mucous membrane to keep the lining of the cells wet (vagina, trachea, esophagus and stomach)
What is facilitated diffusion and how does it work? → movement of molecules from an area of greater concentration to an area of lesser concentration along the concentration gradient. Very slow process. FOR MOLECULES
(Example: exchange of gases in lungs or body tissues)
What is hypertonic? → A solution with a higher salt concentration than in the cells
(cells shrink) LESS WATER THAN IN CELL
Where is genetic coding found? → In the DNA of our chromosomes or our genome. It is found in the cell nucleus.
What is contained in the cranial cavity? → Spinal vertebre
