- What are the 6 types of epithelial tissue?
- What is osmosis and how does it work?
- What is an enzyme and what does it do?
- What is contained in the abdominal cavity?
- What is the cell nucleus and what is its function?
- a 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
- b 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.
- c liver, stomach and intestines
- d 1. Simple squamous -one layer of flat cells (alveoli of lungs, permits diffusion of gases)
2. Stratified squamous- many layers of cells (epidermis, lining of esophagus and vagina)
3. Transitional- many layers of cells (lining of bladder, permits expansion)
4. Cuboidal- one layer of cube shaped cells (thyroid gland, salivary gland, kidney tubules) excretory
5. Columnar- One layer of column shaped cells (lining of stomach, lining of small intestine and absorbs products in digestion)
6. Ciliated- one lay of columnar cells with cilia on free surfaces (lining of trachea to sweep mucus and dust pharynx and lining of fallopian tube to sweep ovum toward uterus)
- e Catalyst: speed up reactions without the use of external energy or heat
5 Multiple choice questions
- 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)
- Involves loss of electron of one atom and the gaining of an electron on another atom (ex: NaCl or salt)
- the response to stimuli does not stop but rather keeps the sequence of events going. (requires an external brake)
EX: cervical stretching during childbirth
- process of cell division that results in the formation of gametes which are egg and sperm cells.
(used for creating human life)
- In the DNA of our chromosomes or our genome. It is found in the cell nucleus.
5 True/False questions
What is filtration and how does it work? → 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)
Describe a disulfide bond? → covalent bond formed between two atoms of sulfur
(ex: strand of hair maintains its shape)
What is homeostasis? → 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 mucous membranes and where are they 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
What areas do connective tissue membranes cover? → meninges line the cranial and spinal cavities and cover the brain and spinal cord. They "line" and "cover".
