- What are the 7 types of connective tissue?
- What is active transport and how does it work?
- What is the cell nucleus and what is its function?
- What are the two main body cavities and what is contained in them?
- What is cellular respiration?
- a 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
- b 1. The dorsal cavity which contains the spinal and cranial cavity
2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
- c 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)
- d 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.
- e 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)
5 Multiple choice questions
- A solution with lower salt concentration than in the cells
(cells burst) MORE WATER THAN IN CELL
- Heart and lungs
- A solution with a higher salt concentration than in the cells
(cells shrink) LESS WATER THAN IN CELL
- 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)
- covalent bond formed between two atoms of sulfur
(ex: strand of hair maintains its shape)
5 True/False questions
What are the different kinds of bonding atoms? → - cell membrane
- cytoplasm and organelles
What is a positive feedback mechanism? → bodys response to stimuli reverses the stimulus in effect turning it off for a while and keeps the body within normal range
Point out cell organelles and name →
What is contained in the abdominal cavity? → liver, stomach and intestines
What are the cell organelles and what do they do? → 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.
