- What is diffusion and how does it work?
- What are the cell organelles and what do they do?
- What are the serous membranes and where they are located?
- What areas do connective tissue membranes cover?
- Describe an ionic bond?
- 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 ER or endoplasmic reticulum- are tubules that transport materials necessary for cell function within the cell.
Ribosomes- are very small structures made of protein and ribosomal RNA and are found on the surface of rough ER.
Proteasome- is a barrel shaped organelle made of enzymes that cut protein molecules apart.
Golgi apparatus- are flat, membranous sacs where carbohydrates are synthesized and are packed with other materials for cellular secretion.
Mitochondria- are oval organelles bound by a double membrane where cell respiration takes place and site of ATP production.
Lysosomes- are single membrane structures that contain digestive enzymes and eat dead cells and bacteria .
Centrioles- are a pair of rod shaped structures outside the nucleus that spindle fibers during cell division.
Cilia and Flagella- are thread-like projections through the cell membrane that can sweep materials across cell surface and flagellum provide mobility of the cell.
Microvilli- are folds of the cell membrane that increase surface area of membrane when needed. They are good for absorption of nutrients as well.
Cytoskeleton- are the framework and support of the cell. Made of microfiliaments.
- c meninges line the cranial and spinal cavities and cover the brain and spinal cord. They "line" and "cover".
- d 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
- e Involves loss of electron of one atom and the gaining of an electron on another atom (ex: NaCl or salt)
5 Multiple Choice Questions
- 1. The dorsal cavity which contains the spinal and cranial cavity
2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
- name for energy production within cells and involves the respiratory gases: oxygen and carbon dioxide
(ex: glucose and oxygen combine to make carbon dioxide, water, ATP and heat)
- 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.
- Line the body tracts open to the environment
---respiratory , digestive, urinary and reproductive
---mucus keeps the living epithelium we and provides lubrication in the digestive tract
---traps dust and bacteria in the respiratory tract
5 True/False Questions
What is contained in the spinal cavity? → Contains skull and brain (CNS)
Review the types of cells by shape →
What are the 7 types of connective tissue? → 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
Describe a chemical bond? → Covalent bonds share electrons between atoms
(ex: H20 or water)
What is mitosis? → process of cell division that results in the formation of gametes which are egg and sperm cells.
(used for creating human life)
