Increase
Decrease
Select ALL of the Following Factors that CAN affect Blood Flow.
Blood Pressure
Heart Rate
Respiratory Rate
Viscosity

What carries oxygen around the body?
Plasma

White Blood Cells
What is the function (job) of the white blood cells?
To transport oxygen around the body.
To carry dissolved sugars.
To clot and cover wounds like cuts and grazes.
To release antibodies to help destroy infections.
What is the function (job) of the red blood cells?
To transport oxygen around the body and to the muscles.
To release antibodies to fight infections.
To carry dissolved nutrients and sugars.
To clot and form scabs if there is a wound on the body.
Pressure exerted on the walls of the blood vessels is termed
Hypertension
Vesicular pressure
Blood Pressure
Heart pressure
Which of the following best describes the connection between cardiovascular disease and age?
As people age, their blood vessels become more elastic leading to less cardiovascular disease.
As people age, the heart becomes more efficient with each pump, increasing cardiac output.
As people age, blood pressure decreases leading to more cardiovascular disease.
As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
An infectious disease can be caused by:
a virus
a bacteria
a fungi
the environment
food
Select all that apply to the term pathogen:
A disease causing agent
cancer, diabetes, and asthma are examples
Bacteria, Fungi, Parasites, and Viruses are examples
Can't be transmitted from one person to another
Can be transmitted from one person to another
A secondary immune response will be faster when...
The individual has encountered the pathogen already
The individual's macrophages are on high alert
The individual has encountered the pathogen and has memory B cells circulating
Antibodies are produced by T cells
How do T cells differ from B cells?
T cells fight pathogens by killing pathogens directly, while B cells fight pathogens by making antibodies.
T cells only make memory cells, and B cells only make antigens
T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.
T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.
defense again pathogen by antibody production in the body after an infection by pathogen is...
Active Immunity
Cell-Mediated Immunity
Passive Immunity
Natural Immunity
What can we do to reduce the rate of development of antibiotic resistant strains of bacteria
Always finish a course of antibiotics
Only take antibiotics when they are really needed
Take antibiotics whenever it is possible
Reduce the amount of antibiotics given to animals in the farming industry
The following organisms can be killed by antibiotics
Viruses
Fungi
Protists
Bacteria
Antibiotic resistant bacteria are a problem because:
It is more difficult to treat people infected with them
bacteria smell pretty bad
viruses them grow out of control
they are not a problem, I love being sick
The process on the right is:
Right: meiosis
Right: cloning
Right: meiosis
Right: mitosis
SC.912.L.16.17
There are two types of reproduction: sexual and asexual. Each type has multiple mechanisms that allow for that type of reproduction and benefits. Mitosis and meiosis are two examples of mechanisms for reproduction. Why does the process of meiosis allow for greater possibility of genetic diversity than the process of mitosis?
Mitosis is the process by which new cells are generated, thereby increasing genetic diversity, and meiosis is the process where exact replica daughter cells are produced.
Meiosis increases the chromosome number by 4, enabling sexual reproduction to occur while mitosis decreases the chromosome number by half and does not increase possible combinations.
During meiosis, cross over in Prophase I allows for the random swap of genetic material while the process of mitosis does not include cross over.
During mitosis, mutations in genes that encode cell-cycle proteins can lead to unregulated growth and genetic variation while the process does not occur during meiosis.
What is an advantage of sexual over asexual reproduction?
Asexual reproduction provides greater genetic variation
Sexual reproduction provides greater genetic variation
Asexual reproduction provides identical offspring
Sexual reproduction provides identical offspring
White blood cells are an important part of the human immune response. Two types of white blood cells, neutrophils and macrophages, act as phagocytes. Phagocytes perform which of the following functions in the human body?
They produce antibodies.
They bind to antigens and develop into plasma cells.
They form a barrier against pathogens.
They engulf and destroy bacteria.
An activity that occurs in the human body is shown below.
This activity helps to do which of the following?
provide protection against pathogens
produce antibiotics to control disease
eliminate harmful gene alterations
regulate production of ATP by the cell
How do human diseases caused by bacteria and diseases caused by viruses react to antibiotics?
Neither responds to antibiotics.
Both respond to antibiotics.
Viral diseases respond to antibiotics; bacterial diseases do not.
Bacterial diseases respond to antibiotics; viral diseases do not.
The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow?
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.
The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.
The narrowing of blood vessels increases pressure and leads to a faster blood flow.
Which of the following factors would most directly affect blood flow through the circulatory system?
blood pressure
blood sugar
respiratory rate
outside temperature
What causes blood pressure?
cholesterol in the blood
stress that exercise puts on heart muscle
contraction of the ventricles in the heart
removal of oxygen from the blood
Which of the following best describes the connection between cardiovascular disease and age?
As people age, their blood vessels become more elastic leading to less cardiovascular disease.
As people age, the heart becomes more efficient with each pump, increasing cardiac output.
As people age, blood pressure decreases leading to more cardiovascular disease.
As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
A fertilized egg undergoes several stages before it is successfully implanted. The diagram below shows these stages as the fertilized egg travels through the female reproductive system.
