HSB CRAM #3 Flashcards
What is Respiration?
The absorption of energy from food.
Why does Respiration occur?
This occurs to provide the body with energy.
What is cellular respiration?
involve the release of energy from the chemicals within a cell.
What is the chemical equation for Cellular Respiration?
C6 H12 O6(glucose)+ 6O2—->6CO2+6H2O(water)+energy.(2880 KJ)
Anaerobic Respiration Definition.
occurs without the use of oxygen. EXAMPLE: yeast cells
Anaerobic Respiration Equation.
C6H12O6—>2C2H5OH+2CO2+energy.
Aerobic Respiration Definition.
this cannot occur without the presence of oxygen.
What is ‘AIDS’?
AIDS (acquired immunodeficiency syndrome), transmissible disease of the immune system caused by the human immunodeficiency virus (HIV).
Name TWO methods of transmission of HIV, OTHER THAN sexual transmission.
- Syringes and Surgical Tools
* Blood Mixing
TWO ways in which babies become infected by mothers with HIV.
Breast Milk
the fetus is infected with HIV through the mother’s blood crossing the placenta.
TWO ways in which babies become infected by mothers with HIV.
- Breast Milk
* the fetus is infected with HIV through the mother’s blood crossing the placenta.
Describe TWO ways of purifying water.
Water Chlorination
Boiling
Suggest TWO water-borne diseases that can be contracted if bacteria are NOT removed
from drinking water.
*Pathogen: HAV (Hepatitis A Virus)
Disease: Hepatitis A
*Pathogen: Cryptosporidium
Disease: Cryptosporidiosis
State TWO functions of water in the human body.
- Participates in many chemical reactions. As a chemical reactant, water is involved in many processes and pathways of the body.
- Helps maintain normal body temperature
Name the vitamin which, when deficient, is responsible for night blindness and
identify TWO food sources of the vitamin.
VITAMIN: A
SOURCE: dark leafy greens, cantaloupe, lettuce
the stages in the digestion
- Ingestion
- Mechanical Phase of 3.Digestion
- Chemical Phase of Digestion(Carbohydrates, protein, and fats)
- Absorption
- Excretion (Elimination)
What is ‘testosterone’?
a steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex.
State TWO functions of testosterone.
- Promotes the development and growth of the penis, testicles, scrotum, and sexual secretory glands.
- *follicular development
In which part of the male reproductive system are sperm made, and where is it stored?
A man’s sperm, which is carried in semen that’s made by glands such as the prostate, is kept in a duct called the vas deferens. Sperm are kept in the epididymis till completely established
Explain how a prostate gland that is NOT functioning properly will affect the fertilization of an egg.
