- What is osmosis and how does it work?
- Describe a chemical bond?
- What is active transport and how does it work?
- What is a negative feedback mechanism?
- What is diffusion and how does it work?
- a 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)
- b diffusion of water through a selectively permeable membrane. water will move from an area with more present to an area with less water present. takes place in the kidneys which reabsorb large amounts of water. FOR WATER
- c requires ATP to move molecules from an area of lesser to an area of greater concentration.
(Example: sodium pumps to move Na+ out of the cells)
- d bodys response to stimuli reverses the stimulus in effect turning it off for a while and keeps the body within normal range
- e Force or attraction between positive and negative charges that keeps atoms closely together
5 Multiple choice questions
- outer boundary of a cell made up of phospholipids, cholesterol and proteins.
its main job is to protect the cell and acts as a barrier for communication and assists in transport
- secretion of an endocrine gland that has effects on target organs
(ex: Insulin - enables cells to take in glucose and lowers glucose levels. Growth hormone - increases protein synthesis and cell division)
- 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
- Positive and negative feedback mechanisms
5 True/False questions
What is mitosis? → Cell division involving one cell with the diploid number of chromosomes dividing into two identical cells.
(used for repair of tissues and growth of the organism)
What are the 3 most popular body planes? → 1. Sagittal plane which divides left from right (cut down the middle would be mid-sagittal)
2. Frontal plane which divides the body front to back (Coronal)
3. Transverse plane which is a horizontal plane that separates the body into upper and lower portions (cuts you at belly button into upper body and lower body)
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 contained in the spinal cavity? → Spinal vertebre
What are the serous membranes and where they are located? → 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
